Re: [Emc-users] Spindle control

[Todd Zuercher]

That is fine if he has spindle feed back, but if not, then the best option is 
to use the at speed output from his VFD.

All you need to do is net the input pin motion.spindle-at-speed to the signal 
from your VFD, it is that simple.  So if your VFD signal is connected to the 
parallel port pin #15, the line in your hal file would be:
net spindle_at_speed <= parport.0.pin-15-in => motion.spindle-at-speed

arh ,
if i'm reading correctly , you wish to use an external output form your vfd
to trigger ? , hence an input pin

the spindle at speed signal is internally generated within linuxcnc , using
the spindle rpm encoder
so therfore does not need an input from the vfd directly to use . so long
as your spindle speed rpm is correct or within bounds of a few rpm
it will work fine ,

I used a near module to develop an at-speed on my lathe.

Grepping for near in the .hal files shows this:
gene@lathe:~/linuxcnc/configs/my_LinuxCNC_machine2$ grep near *.hal
my_LinuxCNC_machine2.hal:loadrt nearnames=near.speed
my_LinuxCNC_machine2.hal:addf   mult2.buttonscale   servo-thread# s/b 
in front of near.speed
my_LinuxCNC_machine2.hal:addf   near.speed  servo-thread
my_LinuxCNC_machine2.hal:netspindle-velocitysumenc.out  
pid.s.feedback near.speed.in2
my_LinuxCNC_machine2.hal:netspindle-drive0  
motion.spindle-speed-out-rpsrvsaccel.in near.speed.in1
my_LinuxCNC_machine2.hal:netspindle-at-speednear.speed.out  
motion.spindle-at-speed
my_LinuxCNC_machine2.hal:# near.speed.in1 is from pid.s.command
my_LinuxCNC_machine2.hal:netspindle-at-speed   <=  near.speed.out
my_LinuxCNC_machine2.hal:setp   near.speed.scale[SPINDLE_9]NEAR_SCALE
my_LinuxCNC_machine2.hal:setp   near.speed.difference   [SPINDLE_9]NEAR_TOL

and a grep for at-speed:

gene@lathe:~/linuxcnc/configs/my_LinuxCNC_machine2$ grep at-speed *.hal
Gearchange_snippet.hal:#sets spindle-at-speed true
my_LinuxCNC_machine2.hal:netspindle-at-speednear.speed.out  
motion.spindle-at-speed
my_LinuxCNC_machine2.hal:netspindle-at-speed   <=  near.speed.out
pyvcp_options.hal:net spindle-at-speed=>pyvcp.spindle-at-speed-led

sumenc.out is the output stage of a lashup that sums the last 4 encoder 
samples and outputs the average, a de-noising technique I have cobbled up.
It lets me run higher gains in pid.s and results in a quite stiff
maintenance of the spindle speed even at speeds down to about 60 rpm
without rattling the gear clearances in the backgear too badly as the 
encoder slots go by.  The fly in that soup is there is not a signal I
can get directly from a Mesa 5i25 card that indicates an edge has gone 
by, so I save the last velocity reading, and declare an edge clocking 
pulse if the next reading has changed by more than a couple counts. 
It probably miss-fires at the higher rpms, missing an edge here and 
there as the shop made encoders slots are going by faster than the 
servo-thread can read it, but by 500 rpm, inertia takes over and the 
speed control remains quite stiff.

I hope its helpfull.

Cheers, Gene Heskett

Re: [Emc-users] Rewiring the BP

[Jerry Scharf]

Hi,

RS232 is an old connection from terminals (DTE) to modems (DCE). at some
point, every wire in the 25 line cable had active signals.

To connect two DTEs together, you need a "null modem" crossover. The most
typical null modem does the following. (I will note the pin number on the
DB25 conector):

Exchanges RxD(3) and TxD (2)  on the two sides
Connects signal ground(7) on the two sides
Connects RTS(4) to CTS(5) on the same side
Connects DTR(20) on one side to both DCD(8) and DSR(6) on the other

The other signals are for things like synchronous modems and the like.

You can get a RS232 Breakout box like
http://www.altex.com/RS232-Breakout-Box-BRB-232-P140389.aspx
to debug things. This allows you to connect and disconnect signals, set
them to values...

Data lines are negative true and signalling lines are positive true.

Yes, I remember debugging 300 baud modems. Then again, people think I also
remember the dinosaurs. :)

DTE/DCE is whether you need to cross the Tx/Rx lines (straight or
cross-over cable).

In a three-wire serial connection you only have two options:
- straight cable (rx-rxd, tx-txd, gnd-gnd)
- cross-over cable (tx-rxd, rx-txd, gnd-gnd)

Most of these serial isolators are powered from the TX lines, so you
must have them connected correctly.

If it has such a beast. I'd assume todays stuff would be expected to have 
that as a given.  But that means you are taking some elses idea of at 
speed at face value.  Since I built the encoder on my lathe, I'd trust 
what I see with a bit more confidence.

OTOH, if the vfd is sufficiently programmable, I'd expect its "near" 
output to be just as valid.  The docs for our near module aren't as 
self-explanatory as I'd like, with my formal schooling I get lost in the 
higher math pretty easy, so I had a bit of trouble setp-ing it to  work 
well most of the time.  Being able to set its target on one input, and 
feed the result into the other ought to work, but there is a scale and a 
tolerance that isn't well explained to this mathematically challenged 
person.  I'd assume that feeding desired rpms into one pin, noise 
filtered rpms from the encoder to the other, setting scale to 1.000, but 
the tolerance exhibited doesn't seem to a +- percentage about matched 
speeds.  I've not looked at it in a while but ISTR I had to apply a 
non-1.000 scale to center its response and that didn't do quite as I 
expected.  But its working well enough to do some rigid tapping OK.

It shouldn't entail very much more than copying the entire config
directory (from ~/linuxcnc/configs) to the new machine.
There are a couple of minor config changes needed, look at "Updating
configuration files" here:
http://linuxcnc.org/docs/2.7/html/getting-started/updating-linuxcnc.html#_updating_configuration_files

You may also need to alter the parallel port base address in the HAL
or INI files

[Emc-users] Spindle control

[lloyd wilson]

I'm trying to add a pyvcp panel to control a spindle vfd. To take 
advantage of the 'at-speed' signal from the vfd to inhibit motion until 
ready, the motion component of LCNC needs to be aware of the spindle 
command state- from the documentation:

*motion.spindle-at-speed* IN BIT

Motion will pause until this pin is TRUE, under the following 
conditions: before the first feed move after each spindle start or speed 
change; before the start of every chain of spindle-synchronized moves; 
and if in CSS mode, at every rapid->feed transition.

but I can't find a reference to HAL input pins for spindle control in 
the motion control component documentation. Is that communication done 
by other methods (NML??- gasp!).

Can someone point me to a sample configuration that properly integrates 
an 'at-speed' signal into LCNC?

Thanks in advance

Re: [Emc-users] Cutsim update

[Les Newell]

Hi Anders,

Just a note to add to the instructions. On a pretty bare Ubuntu install 
I needed

apt-get install libqglviewer-dev libboost-all-dev

I tried opening a file as per the instructions but when I hit play I 
just get an error:

Interpreter exited with error
Unable to a open file.

I have attached the complete debug log.

Hi all,

I was delighted to see that Kasuyasu Hamada has picked up my old cutsim
work from 2011 and made it into a working 5-axis prototype application. It
now looks like this:

and code over here:
https://github.com/KASUYASU/cutsim

It uses a linuxcnc-derived g-code interpreter in a crude way: the rs274
binary chews through the g-code and spits out canon-lines which are then
used as input for the simulator.

I don't have a lot of time to work on this myself but the code-base should
be quite familiar so I can help if someone wants to contribute. I am
interested in the low-level octree stock model and 3D representation - the
stumbling hurdles for me earlier were UI-code, multithreading, and the
g-code interpreter. I've posted this on g+ also in the hope that we'd find
a team of programmers wanting to take  this further.

happy new year!
