Is it possible with Axis to have a GladeVDP side panel, and have a different 
GladeVCP embedded in a tab at the same time? How about multiple embedded tabs?

I've not seen examples how to do this.

The man page for Mitsub_vfd mentions the required settings. Check the scaling 
of the command.

Subject: Re: [Emc-users] Mitsubishi VFD control

I recently set up a Mitsubishi D700 to work with Mitsub_vfd

These inverters are highly flexible in how they are configured to respond to 
control commands. I spent many hours of trial and error to get the correct 
combination of parameters to even get it to respond to network commands. What 
tripped me up initially was that the drive must be reset by cycling the power 
to make any changes take effect.

It has a handy list of all the non-default parameters. I have attached them 
below. Everything appears to work, though there is some inconsistency in how 
manual seed control works in gmoccapy.


The E500 could be a whole different animal but maybe this will help.

Close, but no cigar, it seems.

There is an equation in an online document
(https://archiwum-bazakonkurencyjnosci.funduszeeuropejskie.gov.pl/file/download/587886)
that isn't actually correct:

x'= Dm/2×cosØ −2×e×cos(2Ø)+e×cos(4Ø)
y'= Dm/2×sinØ -2×e×sin(2Ø)+e×sin(4Ø)

However, after getting hold of a pirate copy of the standard, it turns
out that it was only slightly wrong. This is what it should be. ( -+++
not -+-+)

x'= Dm/2×cosØ −2×e×cos(2Ø)+e×cos(4Ø)
y'= Dm/2×sinØ +2×e×sin(2Ø)+e×sin(4Ø)

Plotted out this is very close to the shape that I had but differs by
about 30 microns at the worst spots.

The good news is that this is very easy to convert to either XY
offsets for boring, or a radius for computed offset on a lathe as it
is already in terms of spindle angle Ø.

Re: [Emc-users] c++ gui module

[Chris Morley]

Andy is right there is a functional pyqt5 based VCP component on that branch.

While it is missing some of the fancier widgets that gladeVCP has there is a 
sparce,

but functional demo of controlling linuxcnc.

It is beta for sure and more work is needed but tyer is even some docs...


I should probably put it in master soon...

Not 100% relevant to this discussion, but related: There has been some work
done on integrating QT with LinuxCNC.
See, for example, this feature branch:
https://github.com/LinuxCNC/linuxcnc/tree/qt5vcp_master
[https://avatars2.githubusercontent.com/u/5650508?v=3=400]

LinuxCNC/linuxcnc
github.com
linuxcnc - LinuxCNC controls CNC machines. It can drive milling machines, 
lathes, 3d printers, laser cutters, plasma cutters, robot arms, hexapods, and 
more.


(I know nothing about this branch other than that it exists, though)

Hi Gene,

The docs had a bad example... I've fixed it.

One problem there, is it's supposed to be 'disable_pin' not 'disable'.
Also there needs to be commas between the labels.

Too bad the error message leaves you no clue that is the problem []

I use mitsubishi VFDs particularly the e700 series.

They use a rs-485 serial connection.

I have a python program to communicate with them.


I've also toyed with a Yaskawa drive with Classicladder over modbus.


These are expensive drives to buy new, but can be found on Ebay.

Re: [Emc-users] EDM machining, user interface, increments

[Chris Morley]

I pushed a fix for hal_dial to 2.7 - not sure what you are using.

eventually it will cycle thru to master (and later releases)



The fix is simple (two lines) if you wish to just add it for now.


in gladevcp/hal_dial.py



# handle the scroll wheel of the mouse
def _scroll(self, widget, event):
if event.direction == gtk.gdk.SCROLL_UP:
self._count += 1
self._minute_offset +=1
self._delta_scaled += self.scale #<<<<<<<<<< this one
if event.direction == gtk.gdk.SCROLL_DOWN:
self._count -= 1
self._minute_offset -=1
self._delta_scaled -= self.scale #<<<<<<<<<<< and this one
self._last_offset =  self._minute_offset
self.redraw_canvas()
self.emit("count_changed", self._count,self.scale,self._delta_scaled)

I tested on my machine it seemed to work fine after that.

In sort of the delta scale is a little bit slippery. It slip while using the

Re: [Emc-users] EDM machining, user interface, increments

[Chris Morley]

Hal dial has a pin called delta scale I think. Then changing the scale (by 
clicking) only changes the scale of future dial moments, which is what I think 
you want.

I discovered the limitations of the hal inputs, what is needed is:
  min
  max
  scale
  increment value
  increment value change from GUI
  A choice to between actual or scaled value

None of the do it all.The hal dial may change the scale but what is really 
needed is possibility to change increment value for fine tuning.

Despite these small limitations I still think glade user interface designer is 
really good. Since source code is available it is also possible change, if 
anybody could give me a hint maybe I could look into it but I better start with 
the unfinished g-code database, I think where will be  few hours for it this 
weekend.

If you need truly independent motion, then that it probably correct. I
think that this means two independent PCs, though it _might_ be
possible to have two separate LinuxCNC instances with separate
shared-memory areas.

If almost-independent is good enough (and it might well be) then you
can consider breaking moves in one axis to start another axis moving.

LinuxCNC can drive up to 9 axes, but they do all move in a coordinated way.

Another possibility for things like a cut-off slide would be to
fire-off instances of the simple_tp HAL component.

Hi,
thank you all for you help.

I thought about that, but I could not find 'net' command.

Can this be done from the Python script without calling halcmd?


I just tried this and it worked very well:

h=hal.component("mycomp")
h.newpin("com-pos", hal.HAL_FLOAT, hal.HAL_IN)
h.ready()
msg=Popen('halcmd net emcmot.03.pos-cmd mycomp.com-pos', shell=True,
stdout=PIPE).stdout.read()

h['com-pos'] = newpos


you can make a signal name in python with:
hal.new_sig.(SIGNAME,hal.HAL_PIN_TYPE)

you can connect pin to signal in python with:
hal.connect(PINNAME,SIGNAME)

there are a couple other methods to check for component names and whether a pin 
has a writer.
It's in the source - not officially documented.
Pncconf uses these things - or did I mean.

Does anybody know if the touch probe gcode (G38) obeys
motion.feed-hold?  (I'm guessing it should, but wondered if
anybody knew?)

This Blum probe I got has IR communication, and sends a
single serial byte every 16 ms when there is no event, and
sends a byte immediately when there is a change of state of
the probe.  So, I was thinking I could have a watchdog timer
that causes a feed hold if the IR pickup fails to report for
50 ms or so.  That might prevent ugly crashes if things go
wrong.

Thanks for any comments,

Re: [Emc-users] Spindle control panel breaks LinuxCNC?

[Chris Morley]

Iirc Pressing axis spindle buttons sets the rpm to 1 rpm. Maybe this is the 
problem. Some how that errors the vfd. Depending on what version of lunuxcnc 
there is an INI switch to change that default rpm.You should be able to test 
this by setting the rpm to 1 in the MDI window.
Worth a try.

It's every single time.  If I use M3, spindle runs 100% reliably.  Or, if I use 
my XHC wireless mpg, that runs it fine too.

But on the Manual Control tab, there's a Spindle button with a CW button 
flanking it on the right and a CCW button on the left and +/- buttons 
underneath.  Hovering over the CW says "Spindle CW (F9)".  Clicking on that 
results in no effect from the spindle, and the VFD will not respond to M3, 
nothing can make it run.  It won't run g-code because spindle-at-speed will 
never become true and that's required to be true for G1 moves.  That will 
persist until the VFD power is cycled.  Rebooting LinuxCNC alone will have no 
effect and it's not necessary to reboot LinuxCNC along with cycling VFD power.

This is weird.  The VFD is controlled by a complied .c, which has a limited 
range of communication with the VFD, using a few regs.  LinuxCNC has to have 
sent something that breaks the VFD communication but I'm not sure what it could 
even send that would cause that failure that stores IN the VFD's states rather 
than a state of LinuxCNC's code.  It has to be on the VFD's registers because 
cycling VFD power is essential to recover, while restarting LinuxCNC is 
irrelevant to recovery.

I have a branch somewhere that has a variable spindle speed selection 
incorporated into the motion Component.
The variance range and period are configurable. I wanted it to use a m code or 
g code to set it ..it was roughly patterned after okuma's if someone wants to 
finish the gcode part

There is no need for a new component, it could be easily done with siggen:
http://linuxcnc.org/docs/2.7/html/man/man9/siggen.9.html
Wire the spindle speed request into the "offset" pin and run the
spindle control from the output, enable and alter the dither amplitude
from a slider in PyVCP (or even enable a fixed amplitude with the mist
checkbox, for example).

Just to finish this issue (hopefully).
I contacted Michael H (the coder of remap) about this.
He suggested that codes in remap that create queue-busters
can create problems do to some flow control weakness in
tastaskk/interp.

his refereences 

 https://github.com/machinekit/machinekit/issues/106
 
https://github.com/mhaberler/asciidoc-sandbox/wiki/Interpreter-control-flow-explained

He suggested changing the M6 in the remap code to use emccanon calls
directly:

emccanon.SELECT_POCKET(index, tool)
emccanon.CHANGE_TOOL(index)

I send Rick a new version of the remap and he said it seemed

Linuxcnc doesn't actually support the beaglebone.
It was supported for a while on a branch that was not and will not be merged.
It may be that you are using that old branch of linuxcnc or you may in fact
be using machinekit (a fork of linuxcnc) that does support the beaglebone.

That said if the beaglebone driver supports velocity step mode then it would be
easy to add a stepper as a spindle drive.

 I just switched it over to signal the motion.feed-hold input instead, it 
 stops motion, but how do you get it to resume?
 
 Nothing I push resumes motion.

motion.feed-inhibit is the pin to use as it can't be overridden with an m code.
it will finish a thread move before pausing.

having the pin true pauses, false allows movement.

[Emc-users] FW: Okuma Absolute Encoder

 Subject: [Emc-users] Okuma Absolute Encoder
 
 I'm getting ready to start retrofitting a 1981 Okuma LC30 (OSP-3000
 control).
 
 The axis drives seem to take simple +/-10V commands and use tachs on the
 motors for feedback.
 
 However, from what I can tell, the encoders are some sort of absolute setup
 that doesn't use any sort of battery backup and have about 18 wires. There
 are also no limit or home switches.
 
 I have no diagrams or documentation on anything for this machine. The
 encoders have no visible markings (one looks like it used to, but is worn
 off) except for one that simply says D6.
 
 Does anyone know anything about the pinout on these things or if there is
 any hope of using them?
 
 -Chris Kelley

I have an Okuma flat bed lathe I have converted to linuxcnc (not fully finished 
but works).
I replaced the drives and motors.
I have the manuals for it - OSP2200
I have a pic of the page that shows pinouts.
not much info there.
I sent one encoder to Stuart Stevenson as they were interested in trying one.
Not sure if they ever got it working.

If you figure it out I'd love to hear about it.

 Greetings;
 
 To be specific, I'll have to go someplace and find me at least a 9 pack 
 of switches to setup the homes and limits, else it will not let me pass 
 the x axis config page.
 
 'Twould be nice to be able to bring a 5i25 to life one function at a

 roller lever microswitches is at Lowes if the shack in Bridgeport has 
 also closed.  Last time I looked, Lowes was marked up 4x, and their 
 version of small means you can get 2 of them in a polo shirt pocket.
 
 Sigh...

PNCconf does not require limit or home switches.
It does require the stepper scale to allow past the config page.

 Back to this, I am not sure why, but both of the Milacron controls in

 I guess my question would be, how would I facilitate the line 
 TOOL_CHANGE_POSITION= to disregard the X and Y positional data, and 
 only use the Z value, so as to have no table movement, only a full Z 
 movement, to whatever I tell it to make the tool change.
 
 Our Post Processor that we use already figures in a safety zone to allow 
 for the tool change, and avoid a collision, by moving the X and Y to the 
 appropriate positions.
 
 
 I only ask this to keep continuity among the controls,

Rick you will need to remap M6.
It's a similar idea as the remapping of T for the fanuc style offsets.

The manual has some info:
http://www.linuxcnc.org/docs/2.7/html/remap/structure.html#_specifying_the_m6_replacement

I prefer all python code (no O words) but apparently you can do it either way.

 Chris,
 
 I was mistaken.  There is indeed a 7i84 in the second combo box.  I can 
 select that but then I get the wrong designation for the I/O bits.  That is, 
 I get
 hm2_5i25.0.7i84.0.1.input-00 rather than hm2_5i25.0.7i84.0.0.input-00 (for 
 example).  I assume that is because, as you say, I cannot select the 7i84 on 
 the Connector 3 tab?  Or is it just a bug with the numbering (starting at 1 
 rather than 0)?
 
 -Tom
 

Tab 3 has the lowest numbered 7i84, tab 2 would be the next. that's how the 
firmware describes them.

Pncconf only supports mode 1 and 3 ( question on your other email).
If you need something else then you need to hand edit.

 Yes - if you pick an x axis stepper and x axis encoder (but not an x axis

 I haven't check this in a long time so it might need some tweaks.

 Firmware XMLs must be put in /lib/firmware/hm2/BOARDNAME for pncconf
 to notice them.

I created a directory /lib/firmware/hm2/5i25 and put the 7i85sx2.xml and

add a 7i84.xml file for that to work?  Not sure where to find that, it doesn’t

I down loaded 5i25_7i85_x2.xml from mesa and added to pncconf.
on the connector 2 tab I could select the 7i84 on the second combo box down on

 I thought about using classicladder and few timers there, but the
 thing is that this solution is not easy to adjust for operator.
 Correct timing pattern is unknown at the moment, and I do not think I
 want to provide instructions over the phone on how to use
 classicladder, so I thought that 2 spinboxes in vcp panel as a source
 for the time (in seconds, number of servo periods or whatever) and few
 HAL modules (like oneshot etc) might do the trick, but did not come up
 with anything reasonable, so I was hoping for some hints.
 
 Viesturs
 

In classicladder you can dynamically change the timer time with an assignment 
element.
http://www.linuxcnc.org/docs/2.6/html/ladder/classic_ladder.html#_iec_timers

%TM0.P=%IW0

will set IEC timer 0 at whatever classicladder.0.s32in-00 is

This could be connected to a vcp spinbutton to select the time.

 No text editor to be found. Pressing edit on the File menus does
 nothing ?? Where is gedit ?

It is a configurable item in your .ini file.

BUT!!! Do not use gedit, it has bugs like a 10 day old roadkill carcass.

Geany seems clean and has never trashed a file for me yet, where gedit
has, several times.

They are quite similar, so no new hot keys to learn for most editing.

 I have set the acc and velocities up high using the config editor but
 when running the program, the velocity is about 1/10 I specified. What
 is wrong and how do I change this ?

Is there firmware available for the 7i43, so 
I can use the 7i44 sserial card?
The other connector can be anything.
I looked on Mesa's site but found nothing

ultimately I will use the 7i73 with the 7i44.

Unfortunately the developers that could do this don't see the need nor are

If the developers are not interested it's not going to get done.

You could place some tool change spots using block delete around where tool

block delete on and change your tooling.  Restart program and toggle BD off.

Re: [Emc-users] Problem pncconf in master (patch attached)

[Chris Morley]

  I will look into the kernel check error next.
 
 I have some data for you on that.  I see that pncconf uses the hal 
 python module to learn about the system it's running on.  This is a 
 sensible thing to do.
 

 
 So in other words, in all three of the expected situations, the hal 
 module has good, accurate data.  I did not test the unexpected 
 situations: --with-realtime=rtai on a non-rtai kernel and 
 --with-realtime=uspace on an rtai kernel.
 
 

Ok thanks for that info.
It seems the real problem is the missing kernel version when using uspace.

I'll dream up a patch for you to test with - but tomorrow - bed time :)

There are two new checks in module HAL

is userspace

Can you explain exactly what I can assume if each is true?

is_rt and is_sim basically meant: can drive real hardware/ couldn't drive real

  {
function= BOX
recolorable = TRUE

add to  it:

style spin

  ythickness = 20
  engine pixmap

It is easy to over do this.
In fact to really do this right it is possible to only change the size of

 Subject: [Emc-users] Lathe conversion with Mesa 5i25 / 7i76
 
 I'm back at work on my lathe conversion, reviewing what I have so far, 
 cleaning up documentation, etc. I've run into an issue / question, hopefully 
 I'm just missing something.
 
 I have my spindle encoder connected to the Mesa 7i76 TB3 encoder inputs, 
 which seems to be ok (still have to test operation). I'm looking to connect 
 my MPG encoder somewhere on the 7i76, and I though that could be done on 
 regular inputs due to it's relatively low frequency operation. Looking in 
 PNCConf I don't seem to see an option to put the MPG encoder elsewhere. Am I 
 missing something? Is it supported but not in PNCConf?
 
 Thanks,
 
Pete C.
 

It is supported but not by pncconf.
I believe you have two options.
If the firmware is right, I believe there is a different 5i25/7i76 mode that 
has an MPG input.
That MPG will be specific pins though (check the manual form Mesa)
This is a nice option as there is a x1 mode just for MPGs.

The other option is to load a software encoder counter and use any GPIO
inputs to supply it (even a spare parport)
I'm not sure if you would need a base thread or if the servo thread would be
fast enough - but I would bet the servo thread is fast enough.

Surely others can give you more specific answers.

 The 7i76 only provides one encoder input since it's a stepper card not a 
 servo card. Can you point me in the direction of some docs on loading a 
 software encoder counter and configuring it for MPG use (one MPG, with axis 
 and step select switches). I'm new to LinuxCNC so it takes me a while to find 
 things in the docs (if they're there).
 
 Thanks,
 
Pete C.
 

Here is the example in the manual for an MPG using the parport:
http://www.linuxcnc.org/docs/2.6/html/examples/mpg.html
You would need to change all the parport pins names to mesa GPIO names.

 I seem to have found an earlier point to stall at.
 
 The application is a GUI for my hobber. I want to be able to enter DP

 If I enter a Mod number I want the DP box to be updated to show the
 equivalent DP, And vice-versa.
 
 Unfortunately this ends up in an infinite loop of calls, as the change
 to one invokes a callback that changes the other which invokes a
 callback. ]
 
 In VBA you get round this with Application.ProcessEvents = 0 (IIRC).
 
 Does anyone know how to do the equivalent thing with Python and Glade.
 (Using Glade to create the GUI means no chance to grab the event
 handler ID at event connection time)
 
 module.handler_block_by_func(module.on_change)
 dp.handler_block_by_func(dp.on_change)
 
 Looked like it might work, but doesn't.

Probably the easiest is to add a ignore flag to your handlers.

Then set the ignore flag, call the handler then unset the flag,
ready for the next real entry.

Ugly but it works - This is what Chris R did in TOUCHY.

I have never found a cleaner/easier method.

 Hmm. What I didn't mention is that there are 4 boxes in practice (mm

 them, and just decide who was the new-one on entry.
 
 Maybe I just have to re-think the GUI design.

The caller sends a reference of the widget. So you can check what called the 
handler.

I am not sure what style of handler you are using..

def my_handler(self,widget):
if widget == SOME WIDGET REFERENCE and flag:
return True

again hard to suggest without code in front of me.

 Does that help me distinguish between programatic changes to the value
 and User changes?
 ie it was me, it was you?
 
 Thinking about it, if I end up using a pop-up keypad this might all be
 moot, the keypad can call the update values code.
 
 

Unfortunately not, it only tells you who sent the message.
but since you know _you_ sent the message (by using the flag)
you probably can make it work.

Glade signals options using the glade editor is weak.
In general I create my signals and handlers programmically because of this.
and this particular problem, updating a widget without endless loop seems
common but I have not seen a well thought out (by GTK creators) way.

PNCconf goes to great lengths to overcome this and I would do it different if I
did it again (I'd use flags)

[Emc-users] building a linuxcnc computer

[Chris Morley]

I am interested in building a computer using this mb:
http://www.newegg.ca/Product/Product.aspx?Item=N82E16813157565cm_re=j1900-_-13-157-565-_-Product

( Peter from Mesa mentioned it at some time - I want the PCI and parport)
I do understand it will require a recent kernel.

Can anyone recommend the rest of the required pieces for it?
memory, power supply, ssd etc.

looking for some fairly specific info, I am not up on or very interested
in researching every option.

Thanks for any help.

 I was a bit surprised to see that LinuxCNC didn't have an unconditional 
 jump, ie a GOTO.  I chalked it up to LinuxCNC being written by 
 programmers, and the structured programming Nazis have beaten it into 
 their heads that GOTO statements are evil, and only stupid BASIC 
 spaghetti programmers use them.
 

I tend to agree with you. bad use of goto is .. bad.
good and sparse use of goto is fine, possibly good.

Just look at our beloved HAL code ( coded in C )
you will see lots of goto statements for error cleanup/messages.
makes the code easy to follow and clean.

besides if someone wants to write 'bad' gcode with gotos that
work, who are we to tell them how to program :)

I connected my spindle cmd signal to an abs component. When I set the

Nor does any of the polarity indicators function.
The setup uses a 5i25 with a 7i76 so I had to load EMCMOT with the base

Any ideas?

Re: [Emc-users] Where to get latest PncConf?

[Chris Morley]

  I looked into PNCconf with the  prob_x2   XML file.
  I found a bug caused by Peters's XML's not using the same labels as
  linuxcnc's XMLs. It caused some of the GPIO pins not to show.
  I will push a fix.
  
 Great.  Downloadable by itself?  URL?

I will push to 2.5.x but it is a one line fix in pncconf.py :

line 4683: pinconvertnone = {NOT USED:GPIOI}


  
  It might be nice to add the PIN info to the XML file, then pncconf
  might be able to display better numbers, but it gets complicated when
  using daughter boards.
 
 I got a pinout from mesaflash, by interrogating the card, which does show 
 both component and pins.  Very, very helpful. :)
 

Yes I hand wrote some files for some of the firmware and pressing the help key 
will show them but there isn't any for your particular firmware :(


 
 Basically, all I really need out of the 5i25 is its much higher sample 
 speed encoder, I am happy with the way everything else runs right now.
 
 PncConf makes that encoder config needlessly complex, making me enter a 
 bunch of numbers I don't have instant access to. If we could get the 50 
 slots/rev and x4 settings out of the hal file by default, it would be much 
 easier to setup correctly.
 

Did you realize you can set the scale directly? You don't need to calculate it
using pncconf.  Just type it in the scale box.
I don't understand what you mean by getting the info from the HAL file.

 Once the 5i25 has been setup by disabling what I don't need, does this 
 hold over a powerdown?
 
 Thanks Chris.

After you flash a custom firmware, the firmware will always be the same after
a powerdown. The (de)selection of components to change to GPIO,
is done at load time so will need to be done correctly each time you start 
linuxcnc.

 I believe you just explained it.  And I can't home using the present BOB 
 wiring, home switches are on no pin because I'll have to edit that into 
 the .hal file which I have not done yet. PncConf does not know about home 
 switches yet, or at least I've not found them in the menu's.

Don't press the calculate button, just enter the scale in the spinbox beside it.

 In a manner similar to how it gets the stuff from the .ini file. Could it 
 not read the .hal file too?
 

Pncconf was not made with converting configs in mind, so usually there is no HAL
file to look into and it also doesn't look in the INI file either.

 By loading what file?
  

This is loaded in the HAL file by a line similar to this:

loadrt hm2_pci config= num_encoders=6 num_pwmgens=0 num_stepgens=0

This particular line says: 
enable 6 encoders, (so if the firmware defines 10 the rest after 6 would be 
GPIO)
enable none of the PWM (so all the pins are GPIO)
enable none of the step gens (so all the pins are GPIO)

 I can see some logic in the max-velocity approach, but it is

I can see the utility of a rapid-override pin, in addition to the
feed-override and max-velocity pins we currently have.

The addition of rapid-override would make it easy to implement the
behavior that Mark Tucker desires.

I would be happy to review a patch against master that adds this pin.

Perhaps I should revert to 2.5.x but I moved to 2.6 for the 5i25 support.

I believe I am filling in all the tabs correctly.  This is my first
go-around. I am trying to get a close-enough sample lcnc configuration that
I can start retrofitting an older vmc.

Mesa 5i25/7i77/7i73. Field power applied, red led indicators on both
daughter cards.  Error is the same whether the 7i73 is plugged in or not.

The error:

 I dont know if this has been asked before but hear me out please.
 I wondered why we could not have a number of INI files with an #INCLUDE

 into usable sections like all the AXIS tuning parameters in one file for 
 instance. And then place all the display related stuff into another.

While this is surely doable, I don't think it will be a popular idea with devs.
Mostly because it complicates the INI retrieval code with out much benefit
 
You don't mention why this would be particularly handy

Also the dev list would probably be a better place for this question, unless
you were polling users for support of the idea.

 What files would i have to transfer to machinekit to get gaxis_no_plot 
 to work?
 gaxis_no_plot_handler.py and gaxis_noplot.glade etc.
 Or will i have to do a full install of ubc3?
 Charles did give me the instructions to install your ubc3 and i did try 
 gaxis_no_plot but is it possible to give it another go without this process?
 Also how easy is it to drive from the keyboard?
 

I'm sorry I am not up to speed on machinekit or UB3 but
if you transfer gaxis_no_plot.ini, gaxis_no_plot.glade and 
gaxis_no_plot_handler.py
into the configs/sim/gscreen folder it just might work for testing as a sim.

The INI would be found in confgs/sim/gscreen/gscreen_custom/
The other two in share/gscreen/skins/gaxis_no_plot
These would be in a current master of course.

There is more we can do to lower CPU drag ...
I guess I need to acquire a BBB.. sometime :)

Gaxis_no_plot uses the cursor keys for x and y and page up and down for Z
The manual tab must be showing to jog.

F1 is estop
F2 is machine on.
F10 pops the menu and that is navigable with the cursor keys.

Others could be added

 This is a stepper system, trivkins, 3 axis mill.
 I kind of assumed that the tuning in pncconf is using the configuration 
 that it will write, it's not very useful if one tunes things but then 
 the parameters to use are different...
 
 so you are referring to these
 
   *
 
 /STEPGEN_MAXACCEL = 21.0/- Acceleration limit for the step
 generator. This should be 1% to 10% larger than the axis
 MAX_ACCELERATION. This value improves the tuning of stepgen's
 position loop. If you have added backlash compensation to an axis
 then this should be 1.5 to 2 times greater than MAX_ACCELERATION.
 
   *
 
 /STEPGEN_MAXVEL = 1.4/- Older configuration files have a velocity
 limit for the step generator as well. If specified, it should also
 be 1% to 10% larger than the axis MAX_VELOCITY. Subsequent testing
 has shown that use of STEPGEN_MAXVEL does not improve the tuning of
 stepgen's position loop.
 
 looking at the hostmot driver
 
   *
 
 /maxaccel/- (Float, RW) Maximum acceleration, in position units per
 second per second. If set to 0, the driver will not limit its
 acceleration.
 
   *
 
 /maxvel/- (Float, RW) Maximum speed, in position units per second.
 If set to 0, the driver will choose the maximum velocity based on
 the values of steplen and stepspace (at the time that maxvel was set
 to 0).
 
 seems like it would be best to specify 0 for both of those as the per 
 axis limits would still be in place ?
 I am going to play with that and see... thanks for the reply
 

Don't set them to 0. It doesn't work reliably.
Pncconf sets them to 25% more.

Does your drives require an enable ? I would check that signal with
halmeter or a real meter.

While pncconf uses the same numbers as it tunes ( as long as you clicked accept)
It doesn't use the same HAL code in the test as in linuxcnc so problems can
creep in and bugs are always possible.

Re: [Emc-users] mesa 5i25, pncconf working but not linuxcnc

[Chris Morley]

 I played with those values, setting stepgen.maxvel and maxaccel to 0 
 like the doc says in order to not limit it. Not much improvement. Then I 
 tried to increase vastly the MIN_FERROR, and that allows to go through 
 but I get some occasional grinding noise (missed steps I think) when 
 doing a test (back and forth on one axis)


 One thing I noticed is that the .hal file written by pncconf does not 
 specify the servo_base_period on the EMCMOT line.
 
It's specified in the INI file - the HALfile looks it up there.

 What is infuriating is that within pncconf, I can test one axis with 
 fast movement back and forth and it is real nice, smooth, no missed steps...
 
 Is there a way to find out which exact parameters pncconf is using when 
 it launches the tuning applet ?

Well it should use the parameters shown in the test. If you close the test 
with cancel it won't copy those parameters to the axis page.

But to answer your actual question:
yes there should be a halmeter showing and you can look up the pins
that specify acceleration, velocity and drive timing.
here is a list of the relevent pinnames:
http://www.linuxcnc.org/docs/2.5/html/drivers/hostmot2.html#_pins_3

or you can open a terminal and while the test is running type:
halcmd show 

by the way what version of linuxcnc are you using?

  It might be that Pncconf doesn't teack following error, or has higher

  However, if this is a stepper system then following error means
  something slightly different to what it means in a servo system. It
  means that the system has not been able to make the number of steps
  requested.
 
  What this typically means is that the system stepgen accelleration
  numbers are bigger than the step generator limits. Have a look through
  your INI file and check that the step-generator accel limits are a
  bit higher than the system and axis limits.
 
  Is the machine a gantry system? The other possibility is that the
  step-generator feedback is going to the wrong axis.

Looking at the source code pncconf actually sets maxacc and maxvel to 0
during the test. but that should make the test possibly worse not better.
( and also something I should fix as it should be 25% there too more )

I had already changed the comment to your version but i still have the
same results.
Everything works fine with axis and Gscreen but it will not work with my
custom Gui.
At the end of the day it must be something in the Gui.
I just followed JT's tutorials and it worked fine until i try to put it
in a real setup.

All i wish to do at the end of the day is write a simple Gui for
machinekit that shows the needed info for running a cnc,but without the
cpu usage that Gscreen etc uses.

The simpler standard Gui examples like Mini etc do not even show the
current feedrate etc.

I thought it might be easier to write my own but unfortunately there
seems to be a total lack of current up to date info on this
process,other than johns tutorials.

As an example when using Gscreen/Machinekit cpu usage is about 90% when
idle???
When using mini etc it is around 14%.

I added the emc_stat widget as requested.It put it in objects and shows
up as hal-stat
the power button is still grayed out.?

 There is no emc_stat widget present and no mention of power on in the
 handler file.
 It seems to be purely using the power and estop widgets.
 But the estop widget is useless because we have bypassed it in the hal
 file as stated.

 Chris

 I don't recall any emc_stat widget in the tutorial but i may be wrong.
 I will load up the glade file on my developer os and check

 Yes i did try the Gaxis no live plot but i had lots of errors etc and
 thought i would write my own.
 Big mistake!!!
 1 week later and a lot less hair,and i am just scratching the surface.

 When you say gscreen uses 90% cpu, which skin if gscreen? Gaxis no-gui 
 should be the least cpu hungry. Gaxis second least.

 I had already changed the comment to your version but i still have the
 same results.
 Everything works fine with axis and Gscreen but it will not work with my
 custom Gui.
 At the end of the day it must be something in the Gui.
 I just followed JT's tutorials and it worked fine until i try to put it
 in a real setup.

 All i wish to do at the end of the day is write a simple Gui for
 machinekit that shows the needed info for running a cnc,but without the
 cpu usage that Gscreen etc uses.

 The simpler standard Gui examples like Mini etc do not even show the
 current feedrate etc.

 I thought it might be easier to write my own but unfortunately there
 seems to be a total lack of current up to date info on this
 process,other than johns tutorials.

 As an example when using Gscreen/Machinekit cpu usage is about 90% when
 idle???
 When using mini etc it is around 14%.

 I can confirm the very hight CPU Usage of gscreen gaxis! I use an AMD 
 ATHLON X2-4800+ with 2 GB Ram, not optimized, so no isolcpus etc, 
 because I use this one as development PC.
 
 Gcsreen Gaxis uses 70 % of CPU 2 and 30 % of CPU 1.
Gaxis with or without gremlin?
Sounds like with.
Do you use software opengl or hardware accelerated
Sounds like software.
 
 
 If I startAXIS; It uses aprox the samne amount of CPU Usage.

Yes most of that is the graphics plot

 Original gmoccapy with gscreen background uses 99 % of CPU 1 and 35 % of 
 CPU 2.
 
 I am just making gmoccapy stand alone and I try to optimize as much as 
 possible.
 I can't give values of the CPU  usage yezt.

Cutting the update rate of Gremlin helps a lot - I toyed with the idea of 
making it
settable.
The source_view widget uses a lot too.
We could probably optimize the widgets to use hal_stat rather then their own.

 We're using Mesa 5i25+7i76s in a couple Emco stepper based machines w/
 2.5mm pitch leadscrews.  PNCConf seems to be truncating that 2.5 back to
 2.0 every time we revisit the step calculator page (the pop-up where you
 check off/enter the pulley info, step multiplier, etc.) that calculates the
 main steps/unit box.  It seems to get it right when you enter it as 2.5,
 but if you go back though sometime later (say to change the microstep
 multiplier), it shows 2.0 and you have to catch that and fix it every
 time.  FWIW, I'm running the latest release (2.5.3)
 
 SMD

Thanks for the report.
Yes PNCconf doesn't keep track of the data used for calculation of each axis.
So the data from one axis calculation will be used on the next.

I am in the middle of refactoring pncconf for 2.6 and have fixed it there, due
to your bug report.
When I'm finished I will try to remember to look again at 2.5

Re: [Emc-users] Machinekit Gui

[Chris Morley]

 
 (a) Gremlin needs lots of CPU - I don't know whether it is screen rendering
 without the hardware accelerators that is the culprit.
 

Gremlin's update rate is set at 50ms which is quite high.
I once set it to 100 the plot was only a little more jerky.
(I use software rendering on my laptop.)
maybe we should make it configurable.

 
 (e) The GUI is surprisingly useable at very low rates of updating the
 toolpath, G code and even axis DROs. 1 second is OK. This makes significant
 average CPU savings. The this low rate is tested when running a real
 machine. The audio/visual feedback from the hardware makes the system feel
 snappy even though the screen is lagging. Tests with no machine are
 misleading.


In Gscreen you can set the update rate from the INI
[DISPLAY]
CYCLE_TIME = 100
100 is the default update rate

 A BBB ought to be plenty powerful enough. Perhaps the proper GPU graphics
 will fix things. It would be nice to design an experiment to dummy out the
 graphics work that could be done by hardware or to verify in some other way
 that there are not other bottlenecks.
 
graphics acceleration surely would help a lot.

Re: [Emc-users] Machinekit Gui

[Chris Morley]

 Charles/Chris
 
 How long before these changes with gscreen are merged with the 
 machinekit git repo?
 Or how do i pull the changes from master into machinekit?
 I have done the git pull from master on my developer desktop and the sim 
 works great,now just try and get it into machinekit.

while in a branch of machinekit enter: git merge master
whether it merges cleanly I don't know, but probably.
machine kit is based on UB3 and master is regularly merged into UB3.
So merging UB3 into machinekit may be all you need.

 I also did a git pull in machinekit but could not see any gscreen 
 changes yet.
 I know charles is wanting a 3d printer gui,but i would like to alter it 
 for milling etc,so it should be easy to remove the extra 3d printer 
 stuff like heated beds etc.

Since it is so easy to create skins for Gscreen I would create one specifically
for 3d printers, the Gaxis  skin is just an easy starting point for testing / 
basing.
In fact Gaxis is for milling type machines right now. If you are ambitious you 
can
create your very own skin using Gscreen - Norbert created Gmoccapy as a skin.

 Mark
 
 
 Don't tell it is nearly impossible, as it is easier than ever bevore!
 Take a look at gscreen. It has been designed specialy for that purpose!
 
 As an example gmoccapy is based on that. If you do not want a live plot,
 it is just two steps away, as it can be deleted very easy.
 
 Norbert
 
 

It depends on the skin you want to use, some are more tightly integrated then 
others.
Gaxis is the least integrated:
The process to modify it is to copy the glade and or handler file to your 
configuration folder.
Then Gscreen will use that copy instead of the stock one.
You can then modify them as you like.
You would open the glade file (in the config folder) in the glade editor and 
deleting gremlin.
You made need to delete some references to gremlin in the python handler file.
I have not tried this recently (remove gremlin) so there may be another couple 
other things
 to do as well.

In a RIP linuxcnc the stock glade and python handler files are found in 
share/gscreen/skins/'skinname'

To use the Gscreen skin add this in the INI under [DISPLAY]:
DISPLAY = gscreen -c gaxis
gaxis is the base name for the glade and python handler files.
eg it looks for gaxis.glade and gaxis_handler.py in the configuration folde, 
then the skin folder.

One caveat, is by using a modified glade/handler file , you risk having it 
break do to updates
in gscreen, as your modified files are not updated too.
The risk is fairly low as Gscreen development has slowed and it's easy to fix. 
just redo your changes
on the new stock files.

 The other Gui's like gscreen are just to cpu intensive for the BBB.Even 
 after turning liveplot off.

What skin versions did you try?
gaxis should be the least intensive particularly if you remove the live plot.
(see my other email)

If you tried Gmoccapy without live plot, i am pretty sure it just hides it,
which is not the same as removing it.

There is also a possibility that a second screen was loaded but not displayed
and this screen has a live plot on it as well so would slow things down.
I believe the sample configs always load this second screen... I should check.

So I did check and yes the second screen seems to always be loaded.
on my laptop, using gaxis as is , CPU usage was 20-24 %
I removed the second screen then it was 12-20%
I removed the second screen and the live plot  it was 0-4% (mostly 0)

I will need to push a proper fix for the second screen loading.
I could add a sample Gaxis without a liveplot if you are interested.
(please look at Gaxis to see if it close to what you like - it's AXIS like)

Simply deleting the child block containing gremlin in a text editor

Ok I pushed a second screen fix and a new gaxis_no_plot sample config.
you can find it in sim/gscreen/green_custom/gaxis_no_plot

This has the DRO still available.
It ends up the Gcode view uses up a fair amount of CPU cycles too.
tab to manual while running a gcode program lessens the load considerably.

Switching to less fancy DRO widget may lower it too.

This screen is still geared toward milling machines (it has spindle controls)
but that can be changed.
It is the smallest screen I have made but could be narrower yet if we specified
smaller DRO text.
Note that you can adjust the division between the auto tabs and the DRO by 
mouse click and drag the dividing line.

I'm sure this screen still needs tweaks - it was actually only proof of concept,
feel free to request changes/report bugs.

I remind you this is in master - you will have to merge master into what ever
you are using - UB3?

 Understood.  It seems like a good staring point for a custom interface,
 since there isn't a lot of extra stuff already cluttering up the display.

It looks good, but for some reason the CPU usage on my BeagleBone is
around 50%!

I don't know if this is specifically BeagleBone related, or perhaps due
to the fact that I just pulled the configs/sim/gscreen and
share/gscreen/ directories from Master (skipping anything else updated
outside these two directory trees).

Regardless, it seems responsive enough when I use keyboard jog, so I'll
try and get it working with a real configuration and try moving motors.

Re: [Emc-users] Classicladder with modbus and no GUI

[Chris Morley]

. You will have to find the 
 version that matches the one used in LCNC. For some reason the classic 
 ladder program was not upgraded as time went by. 

This is because it is a lot of work to convert it for LCNC, and there has
been no compelling reason to. If CL supported floats for instance,
I would probably do it again.

In fact LCNC is on it's third version of CL.
Currently we use 7.124

Re: [Emc-users] Python interface: program_open() does not show a preview in AXIS

[Chris Morley]

 in principle those two are unrelated ; of course they should work on the same 
 ngc program. UI's deal with that by telling the preview interpreter to 
 generate preview, and tell milltask to actually execute the program driving 
 the machine.
 
 what happened with your program: you talked to the milltask interpreter, 
 which bypassed the UI - it cant possibly know of the new file
 
 you might want to study axis-remote and the code in UI's to achieve the 
 desired effect: http://linuxcnc.org/docs/html/man/man1/axis-remote.1.html
 
 -Michael
 

If you use master and  Gmoccapy or Gscreen then you could tap into
Gstat's Gobject signal (in your program) and that can emit a 'reload file' 
signal.

another possible way is to use your program as an AXIS filter (master or 2.5.3)
AXIS can load a python program that when finished emits gcode and then you can 
run that.
http://www.linuxcnc.org/docs/2.5/html/gui/axis.html#_program_filters

Not sure if you can make that work...

 Here is a picture of the error that I got when I try to finish a
 configuration using PNCCONF.

 I don't have any idea of what it's talking about.
 

What version of linuxcnc are you using? was this from the livecd and not 
updated?
It seems you are using an old version based on the line number quoted.

We should not be afraid to break things (if it makes sense) on major versions.
Since we will break things anyways if we add ja4 that is the time to break 
everything
else.

I now am wishing we had released 2.6 as it is and worked hard on 2.7 that will 
break
everything.
2.6 is going to take forever to be ready and it's over due now.
Since it seems quite a few people are using 2.6 now we will be breaking their 
configs
anways. (I realize that they knew that could happen, but if you wait so long to 
release
features that are wanted/needed then we are part to blame)

 yes, but automatic migration is possible:
 
 parse the config values out of the ini file, create a .hal fragment using 
 these values to init pin values, and add that to HALFILES=.. after the .hal 
 file which loads  motmod
 

I think we need to plan for changes that will break things occasionally rather 
then 
kludge two ways to do things.
