Jon,

I guess you just have to 'love' standards huh?  heh.  Not to give away my age, 
but the last 'standard' I tried to decipher was NAPLPS.

Now, overlook my ignorance here, please.  What boards do you make?  Mesa boards?

Re: [Emc-users] Looking fro some input from the community

Tomp,

Perfect, the chipset is MCS9865IV and looking at the specification sheet looks 
like it can be configured in a number of formats.  Since yours has a header 
available for the second PP and no UART populated I just listed it as 2 
parallel ports.  One last question and I will leave you alone.  Is the card, 
ISA, PCI or PCIe

I have added it to the list.

Jon,

running the following command will give the Vendor ID and Device ID

lspci -vvknn

vv = verbosity
k = kernel driver loaded
nn = gives both the names and ids of the vendor and device.  The numbers will 
be listed as [:]

The chipset I have discovered is best read from the chip on the card.

[Emc-users] Looking fro some input from the community

2019-04-22 Thread Joe Hildreth

Hello everyone.

I have been working on a series of videos about linuxcnc targeted towards new
user just starting to learn about the controller. In one of my videos I talked
about LCNC and the Parallel port. What I didn't realize was that all parallel
ports are not the same. Some are not really parallel ports at all but rather do
a little VooDoo with the driver to make them work, which will not work with
LCNC. I have a few startech.com parallel addon cards that work fine with LCNC
and have saw others on different websites that work. I also think I read
somewhere about some cards that do not support EPP so don't work with some FPGA
hardware.

So the little side project I want to do, with your help, is to create a list of
parallel port cards and their status with LinuxCNC. Currently, this page is
located at
http://www.myheap.com/cnc-stuff/linuxcnc-emc2/80-my-heap-articles/computer-numerical-control/linuxcnc/196-lcnc-parallel-port-cards.html

I would be more than happy to place a copy on the LinuxCNC wiki, forums and
other places so that its usefulness can be fully realized. The fields of
interest I am looking for are:

Vendor ID:
Device ID:
Chipset:
Manufacturer:
Model:
Notes (This will include any extra information known about the card that would
be helpful to the end user)

There may be more information that should be added to the list of fields, but I
am unsure of what it would be. Leaning on your expertise can help here.

If any of you are running LinuxCNC using an addon parallel port card, if you
would be willing to share the information so I can add it to the list, that
would be very helpful. If any of you have an idea on additional information
that should be added to make it better for the next person to use, that would
be awesome too.

If you want to share but keep the noise down on the mailing list, feel free to
email me at xav...@gtec.com direct.

If you are curious, the playlist I have created from the videos is on the
LinuxCNC forums, or you can get there direct by
https://www.youtube.com/playlist?list=PLaamliiI72ntlrHKIFjh2VjmehRGgZpjm

Thanks for your time and patience with me.

[Emc-users] Parallel Port Docs revisited

2018-07-12 Thread Joe Hildreth

I think I done a poor job of explaining my question, although I believe Andy 
Pugh got it. I created a video demonstrating what I mean, although not the 
great. Was wondering if someone would correct my mis-information or confirm 
what I think to be true. If I am correct, can we get it changed in the 
documentation. 

Here is the video 

https://www.youtube.com/watch?v=QE6tW6W_5Po 

I am sorry if I am being a pain in the a$$

Re: [Emc-users] Parallel Port Driver Docs

Thank you Andy.

  I think the driver works just fine.  I agree that the control port is 
bidirectional.  I would think that the entire control group of pins is set to 
either output (for modes in and out) and set to input (for mode x).  I am just 
trying to confirm this.  This is why I think there is a typo in the table in 
the docs.  If this is the case, can the documentation be corrected?  Honest, I 
am not trying to be a PITA.  Just trying to prepare accurate information for my 
next tutorial.

[Emc-users] Parallel Port Driver Docs

Hello all,

I have been working on a series of tutorial videos on YouTube on CNC for the 
Home Hobbyist.  In the tutorial I am currently working on, I am discussing the 
parallel port.  I want to give as accurate information as I am able.  My 
question is about the documentation found at [ 
http://linuxcnc.org/docs/2.7/html/hal/parallel-port.html | 
http://linuxcnc.org/docs/2.7/html/hal/parallel-port.html ] This documentation 
primarily talks about adding additional Parallel ports to LCNC.  It states that 
there are three modes in which LCNC can use a PP.  These are in, out and x.  It 
also provides a chart showing the pin direction based on the mode that the port 
is set in.

On this chart or table, it shows for the "in" column that pin 14 is an input 
pin.  I think this is in error and should be labelled as an output.  To test my 
theory, I installed a second PCI PP in a computer and run the stepper config 
wizard.  I set up the first port as output and the second as input.

In both output modes and input modes (for the ports) pin 14 is labelled as an 
output pin.  This would make sense considering that pins 1, 14, 16 and 17 
belong to the control group.

So if this is correct, then the documentation needs to be updated to reflect 
that.  If I am incorrect, can someone explain why this pin is input when the 
mode is set to input?

I also understand that in mode x, that the control port (pins 1, 14, 16 and 17) 
are set to inputs but at risk because the physical pins on the port may not be 
open collector.

If you are interested, the play list for the tutorials can be found here: [ 
https://www.youtube.com/playlist?list=PLaamliiI72ntlrHKIFjh2VjmehRGgZpjm | 
https://www.youtube.com/playlist?list=PLaamliiI72ntlrHKIFjh2VjmehRGgZpjm ] I 
have 9 tutorials there and working on number 10.  The idea behind them is to 
give enough information over time that a new hobbyist can get into some form of 
CNC.  Rather than giving specific case examples, I want the information to be 
applicable to whatever they are wanting to set up.  Router, mill, plasma, 
lathe, 3D printer or whatever.  Constructive criticism is welcome, but I do 
give a disclaimer.  I am not a teacher, engineer or a machinist.  Just a home 
hobbyist who wants to give back to the community.

Thanks for your help and input.  It is greatly appreciated.

Re: [Emc-users] parallel ports configuration

I think that would depend on the machine you are placing the cards in.  A SFF 
(Small Form Factor) machine will require a low profile card while a regular 
desktop will take a full size card.

[Emc-users] Beginner Development questions concerning github and git

2017-04-07 Thread Joe Hildreth

Hello all, 

I am new to using git and github and have run into a problem. I apologise for 
the length. 

So first the back story. 

I created a manpage for the hal_manualtoolchange userspace component and I 
would like it added to the linuxcnc repo. These are the steps I took. 

1) I forked the linuxcnc repository to my github account. 
2) I cloned my copy of the repository to my local machine. 
3) While in the master branch, I copied the manpage to 
docs/man/man1/hal_manualtoolchange.1 
4) In git, I added the file to the staging area. 
5) I done a commit and signed it 
6) I pushed the changes back to my repository on github. 
7) I made a pull request to add my changes. 

At this point, I went to the linuxcnc-devel channel on the IRC to make sure 
that I done it correct. Chris Radek was very kind and helpful to me there. He 
seen the changes and merged them. Now when I signed, I misread the docs and 
obfuscated my email address. Chris, seeing this changed the email address so 
that it was not obfuscated and also merged it with the 2.7 branch. Well, the 
next thing I know, as whatever magic happens there, when I go to the website I 
see the manpage in both the 2.7 docs and the 2.8-pre docs. I am happy and feel 
like I accomplished something. 

So I come back here to brag, and sebastian suggests that I am in error about a 
portion of the document. So I want to fix it, so I do the following. 

1) On my local machine, I create am upstream remote pointing to the main 
linuxcnc repository 
2) I pull the upstream to my computer 

This is where it gets fuzzy. 

3) I merge the upstream to my local master and get a message about a conflict. 
4) I done a commit and was supposed to edit the file, but didn't and now it 
shows both changes merged. 

Rememeber Chris changed my email to be correctly formatted. 

5) I committed and signed the pushed to my copy of the repo on github. 

Then I made the following observations. 

It updated the pull request, reflecting my new commit. When I look at the 
changed files, you will see that I didn't make the edit and it shows the plus 
lines and minus lines etc. 

So I need to fix this, and need some advice. My thoughts are to do the 
following. 

1) run a git reset to the previous commit on my local machine, which is Chris' 
merge to branch 2.7. 

If I do this, then commit again, will I get the chance to edit the file? 

What is the best way for me to handle this, so that everything in the pull 
request is right. 

Additionally, When Chris merged the file to branch 2.7, why is the pull request 
still open? 

I am sorry for all the blabber here, but it is kicking my arse a bit. 

Joe

I will be happy to do that.  Did you notice any other discrepancies with the 
man page.  It was a shot from the hip in a way since I am trying to learn and 
document at the same time.  :-)

Sebastian,

Well, what a learning experience that was.  Have the manpage written, forked 
the linuxcnc project, added my page, committed and signed, and done a pull 
request. (With some help from some folks on the devel IRC channel).  At any 
rate, it shows up in the documentation for 2.7 and 2.8-pre so I am happy.  
Hopefully, I didn't butcher the manpage up too bad.

Thanks for the encouragement.

Re: [Emc-users] Documentation - hal_manualtoolchange manpage

2017-04-05 Thread Joe Hildreth

OK, I see what you mean, the change_button is an input pin of the component, 
when it is triggered the component will set the changed pin high.

Some days, I wonder why I get out of bed.  haha

Sorry for all the chatter.

Re: [Emc-users] Documentation - hal_manualtoolchange manpage

2017-04-05 Thread Joe Hildreth

Sebastian,

Thanks for the information and the patience with me.  In the config created by 
stepconf on my machine I see the following in the hal file.

loadusr -W hal_manualtoolchange
net tool-change iocontrol.0.tool-change => hal_manualtoolchange.change
net tool-changed iocontrol.0.tool-changed <= hal_manualtoolchange.changed
net tool-number iocontrol.0.tool-prep-number => hal_manualtoolchange.number
net tool-prepare-loopback iocontrol.0.tool-prepare => iocontrol.0.tool-prepared

So to add the external button, assuming it is on parallel port pin 15 I would 
add the following?

net tool-changed-btn iocontrol.0.tool-changed <= parport.0.pin-15-in

I thought that there would need to be some separation of the two output pins, 
parport.0.pin-15-in and hal_manualtoolchange.changed in order to feed it to the 
input pin iocontrol.0.tool-changed.  That is why I thought of using the OR 
gate.  I was led to this reasoning from the 
http://linuxcnc.org/docs/2.7/html/hal/basic-hal.html page with this line ( I 
have Marked with ***):

=
A pin can be connected to a signal if it obeys the following rules:

An IN pin can always be connected to a signal

An IO pin can be connected unless there’s an OUT pin on the signal

***An OUT pin can be connected only if there are no other OUT or IO pins on 
the signal
===

It looks like I didn't quite understand that.

Joe

[Emc-users] Documentation - hal_manualtoolchange manpage

2017-04-05 Thread Joe Hildreth

I have a good portion of the manpage written for this user component, but have 
a question. 

If one wanted to use the hal_manualtoolchange.change_button as an external 
button, should this input be ORed with the hal_manualtoolchange.changed and 
then the OR output sent to iocontrol.0.tool-changed this giving the option of 
either the dialog continue button OR an external button? 

Thanks, 

Joe

Re: [Emc-users] Missing Documentation - I think

Looking at the ha;_manualtoolchange.py file, I see the following:

h = hal.component("hal_manualtoolchange")
h.newpin("number", hal.HAL_S32, hal.HAL_IN)
h.newpin("change", hal.HAL_BIT, hal.HAL_IN)
h.newpin("change_button", hal.HAL_BIT, hal.HAL_IN)
h.newpin("changed", hal.HAL_BIT, hal.HAL_OUT)
h.ready()

So this tells me what pins are created, the only one I am unsure of is the 
change_button, can someone explain this one?

I know this seems petty, but I am trying to wrap my head around it enough so I 
can teach a few high schoolers what is going on.  Or maybe a little glimpse of 
how the parts fit and work together.  Before I can do that, I need to teach 
myself.

My impression is the hal_manualtoolchange component does the following:

a) receives the tool number via hal_manualtoolchange.number pin
b) receives a command to change the tool via hal_manualtoolchange.change pin
c) The component then opens the dialog informing the user to change to tool #X
d) User does the tool change and clicks the okay button.
e) the okay button send signal via hal_manualtoolchange.changed

am I close?

Gene,

I commented out the following variables:

[EMCMOT] section
 COMM_TIMEOUT = 1.0
 COMM_WAIT = 0.010

[TRAJ] section
 CYCLE_TIME = 0.010

Fired up the machine with the link on the desktop and didn't see any warnings

machine.  I didn't have time before leaving for work to do any more testing.  
(After reading your response a second time, I see you also removed the 
CYCLE_TIME for [EMCIO].  That was not one I was asking about because I found it 
in the INI documentation. although I see your point.)

My setup is parport driven stepper system with configs created by stepconf 
using the axis gui.  I launched the controller with the link that stepconf 
placed on the destop.  Should I be starting it from command line to see the 
error you have or something else?

John suggest I open an issue on this but want to make sure I am not including 
something that I shouldn't or vice versa before I do.

Regards.

Re: [Emc-users] Documentaion Question / Addition

John,

These entries were generated with stepconf, should stepconf be updated so as 
not to include them.  Also, just to verify, all three variable can be removed 
from these two sections?

[EMCMOT] section
COMM_TIMEOUT = 1.0
COMM_WAIT = 0.010

[TRAJ] section
CYCLE_TIME = 0.010

Re: [Emc-users] Looking for advice on LinuxCNC Version

John,

Thank you again for the help and information.  I will try this out when I get 
home.  One last question, when 2.8 is released, is it a matter then of just 
changing the software sources to be on that release or would it be best to just 
keep on the buildbot sources?

Thank you again for your help.

Thank you for the information.  Todd mentioned that I could run the 2.8-pre 
version, but I am unsure how to get it to my wheezy box.  Are there software 
sources I need to point to to do this, or something else.  I would be happy

Also, is there a time line for the 2.8 release?  Should I just wait?

[Emc-users] Looking for advice on LinuxCNC Version

Hello all, 

I built a gantry type router a year or so ago and was more interested in 
getting it running than anything else. My gantry runs along the Y axis and has 
2 motors (joints). I am running the Axis GUI on LinuxCNC 2.6.x. 

My current setup has the ystep and ydir signals driving two motors. Slaved 
together is maybe the word I am looking for. See HAL snippet: 

net ystep => parport.0.pin-04-out 
net ydir => parport.0.pin-05-out 
net ystep => parport.0.pin-06-out 
net ydir => parport.0.pin-07-out 

I have cut loads of stuff with the machine and feel like I am at a point I want 
to make it better. Up to now, I would bump the gantry against a hard stop to 
square it and home the axes by hand. I want to add homing switches which brings 
me to my first observations. 

1) I know that the 2.7 version of LinuxCNC has the gantry component and I have 
looked at a couple of configurations on how that it set up, so I believe the 
gantry joints can be homed independently and squared by adjusting how far the 
joint is moved off the switch. 

2) I have seen a couple of post from BigJohnT were he recommends using the 2.8 
pre version (JA14 branch) as trivkins now handles an axis with multiple joints. 
I have found a little information on this but may be able to muddle my way 
through configuration. 

So, my questions are: 

1) If I am going to go through all the work of setting this up, which would be 
the recommended version? 2.7 with the gantry component, or the JA14 using 
trivkins? 

2) If the JA14 branch is the recommended version to use, how do I get it 
installed? My controller computer was installed using the Debian Wheezy hybrid 
ISO. 

3) Will the JA14 branch eventually be released as version 2.8? If I use the 
JA14 branch and it is released as 2.8, how does that affect me? Does it 
auto-magically become 2.8 or am I still on a developmental branch? If not, how 
do I switch back over to the 2.8 stable release after it comes out. 

If you have references you would recommend for reading, I will be happy to read 
them. Or other advice. I know you guys get a lot of gantry homing question 
stuff and I hope I am not being too much of a pain. 

Thank you for your advice, 

Joe Hildreth

Re: [Emc-users] Documentaion Question / Addition

2017-03-29 Thread Joe Hildreth

It's me again ... :-)

While in the [TRAJ] section of the INI file is see the variable CYCLE_TIME = 
0.010, but is not mentioned in the INI config documents.  I am only guessing 
that this is the polling interval time for the trajectory planner but am not 
sure.  Can I add this to my list?

Thanks again, sorry to be a pain.

[Emc-users] Documentaion Question / Addition

2017-03-29 Thread Joe Hildreth

Hello all, 

I am going through the INI file of my stepper based Gantry machine and am 
looking at the [EMCMOT] section. In this section I see two variables: 

COMM_TIMEOUT = 1.0 
COMM_WAIT = 0.010 

I am guessing they have something to do with the communication times, but the 
INI Configuration section of the documentation does not mention these, and I 
see no reference to them in the core component motion section of the 
documentation. 

Can someone explain these to me and maybe add them to the INI config docs? 

Many thanks for your help, patience and time.

[Emc-users] Documentation Clarification

2017-03-24 Thread Joe Hildreth

Hello all, 

Was reading in the HAL documentation and I found an inconsistency. 

 
2.2 Examining the HAL 

In the section under Show Pins the following text appears: 

"... hundreds of pins. But right now there are only nine pins. All eight of 
these pins are floating point, and carry data out of the siggen component. 
Since ..." 

I think the work "All" in the "All eight of these pins" Should be removed, or 
perhaps the text changed to mention the other "bit" pin. 
 

I hope this was the place to mention it. 

Thanks, 

Joe

Andy,
You linked a site that sells ball nuts. Is it possible to change a ball nut
only, assuming the screw has even wear? I realize that there are there are
considerations for mounting and such, but I had the feeling that the screw
and the nut were made as a set.
Sorry to interject slightly off topic, I'm trying to educate.

Re: [Emc-users] OT: Grind a hemisphere or ball end on rod

2015-06-06 Thread Joe H

That set up sounds sensible. It made me envision  a simple arrangement
using a mounted angle grinder on a fixture with different pivot points.
Maybe CNC not needed at all.

 In point form

 - lay the rod in a long V (angle iron will be fine)
 - rotate the rod at about 10RPM from the far end with a small reduction DC
 motor and a 3-jaw chuck
 - at the working end, support the rod with two large (80mm) overlapping
 rollers (like used for balancing)
 - have a third roller lightly pressing down
 - make a small X-Y table and mount a grinding wheel on it (axis of grinding
 wheel is parallel to rod)

 - system is easy to load and unload
 - you can program the X-Y to any arc you like, and is easy to edit the code
 - have a sharp point nearby so you can dress the wheel automatically
 - since the X-Y is very light duty, you could use as small as 4mm threaded
 bar for the feedscrew. Light spring pre-load and brass nuts.
 - best to use rollers instead of slides for the axes.

  I thought I'd throw this out here because some of the ideas passed around
  are really good.  I thought someone might have a helpful suggestion.
 
  I have an application where we need to grind a ball-end on the end of rod
  that can be between 0.5 meters to 2 meters long and vary in diameter from
  about 1.25mm to 8mm.  Currently, it's done by hand on rotary disk sander.
  The material is stainless steel or titanium.
 
  It seems like a solution might be a small cnc'd lathe and bar feeder type
  application and it needs to be easy to use and quick.
 
  1.  How do I cut/grind the hemisphere?
  I'm thinking a small CNC type lathe should do it?
  I read on practicalmachinist.com that for manual lathes they often use a
  custom tool at the radius they want to cut, but I have varying radii, so
 it
  didn't seem like that would be a good solution.  Using a CNC would solve
  the varying radii problem.  Either a sensor or operator manually enters
  dia.
 
  2.  How do I hold and spin the rod?  Especially, w/ differing diameters
  that can show up at any time.  Here were some ideas, but they don't
 handle
  the differing diameters?
  http://www.processwelding.com/standardLathes.php
  http://www.4machining.com/4m-Tooling/Harig-All/Harig-Air-Collet-Closer
 
  What about a large rolling wheel driving against two idlers to rotate the
  bar?
 
  3.  Lastly, controlling the whip while the stock is rotating?
  I could see a barfeeder type application and then something to keep the
 rod
  from whipping?
 
  Thanks,
  Mark

[Emc-users] Classic Ladder and PyVCP Question in Stepconf

2015-04-28 Thread Joe Hildreth

Hello all, 

I posted the stuff below to the forums, but thought I would ask here as well. 

I was playing around with StepConf Wizard last night, looking at what exactly 
was added to the configuration files when you make selections on the Advanced 
Configuration page. I have determined the following. 

To keep it short, when selecting the check box under PyVCP to include 
connections to HAL seems to produce no new code, but I suspect that is where 
the line 

POSTGUI_HALFILE = custom_postgui.hal 

is added to the [HAL] section of the machine's INI file. 

Is mu assumption correct on this? 

Second, when selecting the checkbox for including connections to HAL under the 
classic ladder section seems to produce no changes in the config files, but 
again I suspect that this line 

HALFILE = custom.hal 

is added to the [HAL] section of the machine's INI file. 

Is this assumption correct. 

Also, I noted on a new Stepconf Wizard config, without using PyVCP or HALUI, or 
Classic Ladder, the same two files are added to the machine's INI file. 

Now, I understand that custom.hal is where you can put connections for your 
ladder program and not worry about them being overwritten if you use Stepconf 
again, and the custom_postgui.hal file exits to create connections after the 
GUI has been created. So I suppose my question is the following? 

Are the two above mentioned check boxes meant to perform this function or do 
they actually do something else? 

If they are meant to provide this functionality, then they seem unneeded 
because stepconf will create the entries whether you want them or not. 

I know it is an obtuse question, but I just want to make sure I understand what 
is happening behind the scenes.

Re: [Emc-users] Adding linear scales to stepper system - any advantage ?

2015-04-25 Thread Joe H

I put encoders directly on the screws of my knee mill. It was tricky to
mount on the y axis. I used one with a through hole and put it where the
micro dial was. I'll see how it works out if I ever get it going.

 An encoder anywhere on the ball screw would work.  It's usually easier
 to mount an encoder on the end of a ball screw or motor shaft rather
 than between the motor and the ball screw.  There are motors with a
 shaft protruding on each end and it's common practice to mount the
 encoder on the back shaft of the motor, with the shaft coupling to the
 ball screw on the other side of the motor.  That's what I was
 discussing.  There's nothing wrong with mounting the encoder on the back
 of the motor if you want to catch the common problem of missing pulses
 on a stepper motor, but an encoder on the back shaft of the motor would
 have no way to detect positional errors caused by a slipping shaft
 coupler.  It would see the motor turning as commanded, and would have no
 way to see that the screw isn't turning with the motor because the
 coupler is slipping.

 BTW - For very precise machines, even a large diameter ball screw is not
 a solid screw.  There is measurable torsional twist when accelerating
 and decelerating that can cause minor positional error that is
 significant in some precise applications.  One trick that's used is to
 place an encoder on each end of the ball screw and detect the slight
 difference in rotation from one end of the screw to the other due to
 twisting.  Some math is done to compensate for the positional error that
 would be caused by the twisting ball screw between the motor and the load.

 LinuxCNC does a good job of compensating for backlash when it can, but
 software can only do so much.  Backlash is still a limiting factor that
 degrades CNC performance.  Position feedback isn't really needed for
 backlash compensation as backlash can be measured and is repeatable and
 predictable.  However, position feedback is very useful in detecting
 other positional errors and shutting down the machine, possibly before
 ruining a part and probably before crashing the machine.  These would be
 the errors that occur because a stepper motor loses steps or a shaft
 coupling is slipping.  Most stepper motor based machines use large
 enough stepper motors that they aren't on the edge of losing steps, to
 provide confidence that the stepper motors are moving as commanded.
 Servo motor based systems can run closer to the edge, because the
 position feedback is constantly monitoring the position.  Closed loop
 control is needed for servo systems, but it provides good peace of mind
 in stepper systems as well.

 A relatively easy way to add position feedback is to put a rotary
 encoder on the lead screw or ball screw, on the end opposite the motor.
 Adding an encoder on the other shaft of a dual shaft motor would detect
 lost steps, but would be unable to detect a slipping shaft coupling.
 Your linear scales should detect all positional errors.

2015-04-14 Thread Joe H

I'm having problems getting started with 5i20 7i33 7i77. I began this
project a couple of years ago and was delayed for various reasons. I have a
mid 80's  Mill with brushed servos that run. Nothing has been done to the
wiring of it yet. I want to get it running with Linux CNC. I am going to
ask some questions that I'm sure will show my ignorance. I have Ubuntu
10.04 with Linux CNC  installed on a P-4 that shows good latency. The 5i20
is in the PCI bus, the 7i33 and 7i37 are plugged in I believe the correct
way. I have used the wizzard to configure for 5i20 and 3 axis servo to the
best of my abilitiy. I believe that the card is recognized (lights up red,
then goes out when I start Linux CNC). Should i get pin-out info by
typing   dmesg  hm2.txt   in terminal? I believe I it showed up once
yesterday but haven't been able to get it today. dmesg does show
information, but no pin out.I could use a pointer in the correct
direction.  I've been reading the manual but I am stuck.

2014-11-10 Thread Joe Hildreth

All,

I just wanted to take a minute and thank all of you for the help, links, 
advice, (c).  I really appreciate it.

I have decided that I will bring the software estop out and use it with the 
mechanical estop(s) to just drop all the power from the motor drivers, Router, 
Vacuum, (c).  I will also bring the estop condition back into LinuxCNC, not 
because it really matters, but just so the software recognizes the stopped 
condition.

Again, thanks so much for all you help and advice.  I really was over thinking 
it or something.  Having been in computer networking in the healthcare industry 
for the last 15 years, I have got into the habit of over thinking as part of 
the CYA you perpetually have to do because the government constantly mandates 
it.

You folk really are a blessing to have as a community.

 You don't wire the coils of relays in series for relay logic.  The coil
 voltage is selected to match the voltage you want to use to activate
 it... 5VDC, 12VDC, 24VDC, 120VAC, etc.  You wire the relay contacts in
 series to implement an AND function (as is the case with your E-stop
 switches and a relay that mirrors the status of the internal LinuxCNC
 E-stop signal, and any other relay controlled signal you want to
 generate an E-stop).  You'd wire the contacts from different relays in
 parallel to implement an OR function.
 
 The reason I suggested using relay logic for this application is
 simplicity.   You'll need a relay to externalize the internal E-stop
 status anyway, so just wire the contacts in series with any E-stop
 switches you have and you're finished.  Why add any discrete logic ICs
 to that?  It's needless complexity.
 
 I'm generally a big fan of implementing logic in software or firmware.
 I've replaced a lot of goofy 1950s technology relay logic where relays
 and electromechanical timers were used in the 1990s because someone
 didn't know how to use a PLC or (my favorite) a one dollar RISC
 microcontroller.  But if you already have the relay and that's all you
 need, why add an Arduino to drive the relay?
 
 If you search for E-stop circuit and look at the images, you'll see
 lots of examples and it'll make sense.
 
 There are also some standard circuits for input power disconnects (I
 don't go to that formality for my small CNC machines) with
 fuses/breakers, ON and OFF pushbutton switches that latch the ON
 condition until the OFF button is pressed, etc.

[Emc-users] A beginners question about E-Stop and Charge Pumps

Hello everyone, 

I am sure these questions are asked all the time but I have found nothing that 
really covers what I am looking for. (But maybe I am not too good with the 
search.) 

I have built a CNC Gantry router based on the KRMx01 design from Kronos 
Robotics. But instead of using the electronics and Mach3 he suggested, I am 
using electronics, motors and Linux CNC. 

The basic machine is up and running and I am using it to cut more parts for the 
machine. I am to the point now that I need to think E-stop, limit and home 
switches, vacuum control (dust collection) and router PID. 

My setup is a C10 (cnc4pc) BOB, (4) CW230 stepper drivers, (2) 36vdc power 
supplies (each feeding 2, CW230 drivers) and (1) 5vdc supply enabling the BOB. 
The CW230 drivers do not have a charge pump or anything like that, though they 
do have a pin called REST that according to the sparse documentation says will 
allow the motor to free spin. (I guess it may be considered an enable) 

Because I have a couple of teenage boys and a wife who have expressed an 
interest in using the machine, I need to make sure it can be stopped in the 
event something unplanned happened. Here is my thought and also where I need 
some guidance on best practice or acceptable practice. 

1) Connect external E-Stop to input pin on controller 
2) Use HAL to logic glue the AXIS GUI estop and AXIS GUI Power button together 
so that IF both E-Stops are on the closed position AND the power is on in AXIS 
GUI THEN allow charge pump signal on output pin of BOB 
3) Connect cnc4pc part C4 (charge pump) inputs to charge pump signal on the 
corresponding output pin on the BOB. The output of the charge pump is a relay 
with the choice of NO or NC contacts. If the charge pump frequency falls above 
or below the operating threshhold, then use this output as a trigger. 
4) Connect the output to (2) C8 (cnc4pc part number) AC relays with 5 volt 
input to connect / disconnect the AC side of the (2) 36vdc power supplies that 
power the CW230 stepper drivers. 

In my simple mind, this should provide the following safety feature. 

A) The machine will only run if both E-Stops (external E-Stop and AXIS GUI 
E-stop) are in the closed positions AND the power button (AXIS GUI) is on. 
Allowing the Charge pump signal to be generated on the output pin of the BOB 
enabling the power to the motors through the Charge Pump and AC Relays. 

B) If either Estop is opened, then the Charge pump signal will be stopped 
causing the power to the supplies to be cut by the AC Relays from the Charge 
Pump. 

C) If the computer crashes and the LPT port is left in an unknown state, the 
charge pump signal should be gone causing the power to the motors to be cut. 

D) Avoid any start up random signals to the LPT port being sent to the motors 
because the drivers will not be powered up. 

Kind of long, but am I on the right track here. Just want to have a margin of 
safety if my boys or wife is trying to use the machine. 

If you are interested, I have a detailed build of this machine, including 
screen casts of LinuxCNC hybrid install, configuration to this point, etc on my 
website which you can see by going to 
http://myheap.com/krmx01-cnc-router/krmx01-build-log.html 

I will be adding this (E-Stop, charge pump, AC relays) to the pages too 
including how to configure and the logic behind the solution. I am hoping it to 
be a resource to others like me who are only in it on the hobby level and still 
have the HUGE learning curves to make it over. 

Many thanks, 

Joe

Re: [Emc-users] A beginners question about E-Stop and Charge Pumps

Bruce,

Thanks for taking the time to explain it to me.

So I can take this approach then:

1) Use the internal E-Stop as an output on the BOB (Use this as in input to my 
AND gate)
2) Use the external E-stop which is normally closed as the second input to my 
AND gate)
3) Use the output of the Charge pump signal from the BOB as the third input to 
the AND gate.

4) The output of the AND gate to drive the TTL inputs of my AC Relays to 
enable/disable power to the motors.

This way, I still have both E-Stops (Or additional ones by cascading E-stops) 
and the charge pump signal to rely on?

I could make a PC board for an AND gate with Vcc and ground in with a 
decoupling cap and just bring the inputs and out puts to screw terminals.  This 
way, it would be nice and modular, cheap and fit in any corner of my 
electronics drawer that slides in the computer rack.

My spindle is a Hitachi router, so not sure if it is even possible to brake.  
It will get wired to a SuperPID so that I can control on/off and motor speed 
via software.  I need to look at the documentation and see what I have 
available in terms of E-Stop control.  It may be that I have to treat it like 
the stepper driver power supplies.  I am just not there yet.  I still consider 
myself a newbie so am trying to take it in digestible BYTES.

As far as the external charge pump.  I am thinking that LinuxCNC will only 
generate the carrier frequency (charge pump signal) when it has control.  This 
way if the computer hangs or crashed I would at least have an additional level 
of safety.  Or am I just over thinking it?

Thanks again for your help.

Joe

 Hi Joe,
 
 The industry preferred method of implementing an E-stop would be the
 opposite of what you propose.  Rather than using the mechanical E-Stop
 switch as an input and logically ANDing the external E-stop switch and
 the internal E-stop machine state, you should use the internal E-stop
 machine state as an output and use electronic hardware (relay logic) to
 AND the E-stop switch and the E-stop machine state to enable the spindle
 motion and the X/Y/Z motion.  To be clear, you're actually ANDing the
 non-E-stop conditions, or NANDing two E-stop signals.  However you want
 to say it, motion should only be possible when the PC based controller
 says it's OK to run, and when the E-stop switch says it's OK to run.
 
 The issue is the reliability of computer hardware and software. These
 have greatly improved, but are still not up to the reliability standards
 of relays.
 
 I like solid state relays, although E-Stop relays are usually clackity
 relays with mechanical contacts.
 
 Consider using multiple E-stop switches if someone could be pinned by
 part of the machine.  Try think of all of the things that could go wrong
 and make sure someone could quickly reach an E-stop.
 
 When wiring your E-stop circuit, make sure the E-stop switch contacts
 are closed when you want the machine to run, and open when the E-stop
 switch is activated.  That way, if there is any loose connection in your
 E-stop circuit, the wiring fault causes the machine to fail in the
 E-stopped condition.
 
 The simplest E-stop wiring would cut power to the spindle motor and all
 of your stepper motor power supplies, even though the spindle could
 probably be actively stopped faster if left under power and commanded to
 stop rather than coasting to a stop.

Re: [Emc-users] A beginners question about E-Stop and Charge Pumps

Bruce,

One more question.  If I wired it like my last email, then LinuxCNC would not 
have any clue that I hit the external E-Stop.  Would it be benifitial to bring 
the signal back in anyway, just to let the software know we killed it 
externally?  Otherwise, I imagine that the software will continue to send 
motion information and continue to plot like nothing ever happened.

Thank you.  I see your point.  Sometimes I get tunnel vision.  Would you

 Joe,
 
 Your last request is what happens where you hit 'pause', e-stop is for
 emergencies.  It should be used to keep from loosing a hand, or to
 keep the equipment from tearing itself apart.  Pause is to stop in a
 restartable manner.  The machine may have to finish a cut before it
 can pause, but using e-stop means you are willing to lose the piece or
 repair it if something is wrong.
 
 I hope that helps.

Re: [Emc-users] A beginners question about E-Stop and Charge Pumps

Bruce,

Thanks for the information.  You gave me quite a bit to chew on.  Having a 
computer and electronic background I tend to think of logic being implemented 
via discreetly or through a micro-controller.  I never really thought about 
relay logic.  I have never tried to implement a logic circuit with relays, so 
would have to look at some samples.  Off the top of my head it would seem that 
driving coils in series would be an AND and the same coils in parallel would be 
an OR.  But beyond that no clue really.

You said I shouldn't use IC to implement logic, but aside from the Y and !Y (NO 
and NC contacts) output logic why do you recommend against it?

Currently, I have 5Vdc, 36Vdc and 110Vac that I am dealing with.  Seeing that 
the 5Vdc power supply supplies my BOB, and other future devices, TTL logic just 
seemed natural.

I agree with you about the software E-Stop versus the Hard E-Stops.  I will 
insist to my Boys and wife that if SHTF, ALWAY hit the big red buttons!

Thanks again for all the support, advice, direction and resources.  I 
appreciate it.  I see I have a little reading on the subject to catch up on.

Regards,

Joe

wrote:

 You shouldn't use integrated circuits to implement the AND logic.
 Instead, use relay logic.
 
 The output from the BOB that represents the internal E-stop state in
 LinuxCNC is wired to a relay.  If the BOB can't source enough current to
 drive the relay, you might need to use a small relay to operate a larger
 relay, but you don't need a high current relay for the relay logic.  You
 only need a small ice cube relay and the BOB output should be able to
 drive it directly.  If you select a relay with normally open and
 normally closed (NO and NC) contacts, you can select the correct set of
 contacts as you wire it to negate any signals that may be an opposite
 logic state than you assumed. That's a handy feature for flexibility and
 can come in handy for future add-ons.  It's easy to make one wrong
 assumption about signal polarity and have the opposite of what you need
 at the final relay in the circuit, and having NO and NC contacts on your
 relay is never having to say DOH!
 
 The logic relay that represents the LinuxCNC internal E-stop state is
 wired in series with any E-stop switches you installed.  That way, if
 you push any E-stop switch, or click the E-stop button in LinuxCNC, the
 machine goes into an E-stop state and all motion stops.  The signal that
 passes through the E-stop switches and your small relay contacts then
 operates a larger power relay that supplies power to all motion control
 (spindle, steppers, etc.). This power relay can have multiple sets of
 contacts, so each motion producing device can be controlled separately
 if they use different voltages.  A set of contacts can be used to
 control your Hitachi router.  Another can control the stepper motor
 powers supply or power supplies.
 
 You can also include a set of contacts to control a digital signal that
 feeds back as an input to the BOB so LinuxCNC can determine that you
 pressed an E-stop switch, although for my simple machines like routers,
 I generally don't bother because that takes a bit of messing around in
 HAL, and I like being able to install a new copy of LinuxCNC, select a
 generic stepper gantry router configuration, tweak the machine limits
 and steps per inch, and Bob's your uncle. I don't plan on pushing the
 E-stop switch, and if I do, I don't mind if the program keeps running as
 long as the motion stops.  I'm going to reset everything, anyway.
 
 Similarly, for a simple machine, you might skip the relay that
 externalizes the internal LinuxCNC E-stop state.  You'll probably press
 a physical E-stop switch on the machine, but clicking the E-stop button
 in LinuxCNC would still stop the motion even if it didn't generate a
 real E-stop.  The difference is, the motors would still be powered and
 would be holding position, potentially keeping the operator pinned.  If
 you trained everyone to ignore the E-stop button in LinuxCNC and push
 the E-stop mushroom head switch on the machine, it wouldn't be too much
 of a safety problem IMO.  If it's an emergency, the operator shouldn't
 be mouse clicking or trying to press hot keys on the keyboard, and I
 don't think they should be trusting any PC software, even if LinuxCNC is
 very robust.  I don't believe in software E-stops.
 
 If I was wiring it, I'd probably use a solid state relay ($6 each or
 less on eBay) for each motion device I needed to control and use the
 E-stop signal to control them all.  I know they'd work for the 120VAC
 power for your Hitachi router and the DC power supplies that dive the
 stepper motors.  If I had any three phase devices, I'd use a three pole
 relay (actually, a motor starter) to ensure that all three phases were
 switch on and off at the same time.
 
 If you do an online search for E-stop circuit, I'm sure you

I was reading through the Getting Started V2.6.3-19-g06655d0, 2014-09-16 
manual. 

Section 4.6 Mechanical Information. 

In the first example calculation, the text list 8 microsteps in the formula, 
but should read 10 microsteps 

I hope it is OK to pass along corrections. 

Regards, 

Joe

Re: [Emc-users] CoreXY Kins and the BeagleBoneBlack with MachineKit

I actually did try that, but with no luck. I tried a couple  other kinemtatic 
models. Gantrykins and delta, with similar results. 

The net Pin assignments are all the same as they are in the example K9 PRU 
config.

 Moving in the x only moves the X motor, same for y.
 
 Is there something I will have to hook together in my net pins? Im
 guessing it would be similar to slaving two axes together like in
 gantrykins?
 
 Again thank you for the help.

When you start LinuxCNC with non-trivial kinematics, you're in joint
mode by default, where you move each joint independently for homing.

Once you've homed all the joints, switch to world mode and X/Y/Z jogs
should work as expected going through the kinematics module.

Re: [Emc-users] CoreXY Kins and the BeagleBoneBlack with MachineKit

Here is my config. At this point its still the same config that Probotix 
supplys with the exception of changing to from trivkins to core_xy_kins.  

A CoreXY or Hbot machine works on the same principle, driving the X and Y axis 
from the same belt that is routed along the lengths of the axes. Its all 
explained here, http://corexy.com/theory.html. In this setup to move in say X 
both Motors will have to move together, in the same direction. If you are 
driving to a 45deg angle, one motor moves. So somehow I have to connect the xy 
motors to deal with this. I imagine it would work similarly to how a delta bot 
is configured. 

I just attached the config. If I need to post it in plain text just let me 
know.

What sort of machine is this anyway?  I only briefly reviewed the
foreign language links you provided...partly because I can't read the
text, and partly because I hate forums.  ;-)

Here is the kinematics file as well. 

Thanks again for all the help!
