You might try Petegruende...@att.net
Years ago he put together a sinker driven by basic code. One of the 
demo's was a thread cut
in a file. ;-)  There is a massive thread on emc_dev about feed and gap 
control. Also you might
want to contact Steve Stallings as he did  some work on a board some 
years ago.

[Emc-users] EDM

[Nicklas Karlsson]

Finally I start to get together both hardware and software including generator 
for my EDM machine.

I work with electronics and are new to mechanical machining and EDM in 
particular. Do anybody know if anything more than adaptive feed rate including 
backwards have been done for EDM?

Re: [Emc-users] LinuxCNC as laser cutter?

[Danny Miller]

I've been inside Universal Laser Systems lasers.  The laser doesn't have 
a throttle, just an on/off for the beam, and it's like this:

The beam is about 0.008" dia, 1/125th of an inch.

If you specify <100% power in vector mode, there is a Pulse Per Inch 
(PPI) factor used.  If you specify 50% power 300 PPI, it cuts at 1/600th 
in on, 1/600th in off. When it's on it's full power. That's not wide 
enough of a stop to leave any unburned length. For any given point, it 
receives less exposure to the beam.

When hitting the corners of a square, of course, acceleration rules 
apply to full stop/full start the vectors, and since it's less than the 
commanded speed, the exposure would be increased past the specification. 
So it does add a  DIFFERENT pwm to reduce power when the speed is below 
the target command, but it's fast- like 1000 pulses per inch, or might 
be in the time domain, I don't know.  It's not affected by the commanded 
PPI.  This does seem to mean that if you command 50% power and 500PPI, 
when it does the start/end of vectors and isn't at commanded speed, 
there's a series of 1/600th in on/off segments, AND within the ON 
segment it's pulsing at 1000PPI.

With rastering, there's two modes.  One is more "analog" and does high 
frequency PWM based on shade as it passes.
The other uses a fixed-length PWM as it goes, based on shade. Like on 
333 vertical raster lines per inch, it has a 60-lines-per-inch 
horizontal resolution.  That is, a 127 value in an 8-bit greyscale is 
1/120th in on, 1/120th in off.  It's an offset pattern, every other line 
starts 1/120th of an inch offset, to make a diamond-shaped grid.

There's also random-density mode, where it makes dots.  But it's hard to 
really nail down what it's doing- the laser must burn in a line.  It 
can't actually do a circular dot without stopping, which it doesn't do.  
It can burn pill-shapes of varying lengths.

Just thinking on this- you COULD specify that a straight 50% power 
vector line is a long string of G-codes- M62, one  G11/600th in segment 
on, M63, one G1 1/1600th off, interleaved over and over. It would be a 
VERY long file, and might have slow execution, and won't take into 
account acceleration.  Also, it is not uncommon to want to change power 
on the fly, and that'd be impossible- you'd have to regenerate the whole 
G-code.

FYI, in my experience with ULS lasers, yes you can change the speed & 
power of VECTORS on the machine after the job is generated.  However you 
cannot change the number of vertical lines per inch on rastering.  You 
can change the raster speed.  Which makes sense.

So the way I interpret it, no, that's all totally wrong to generate 
G-code pulses within the vectors, instead you'd generate the PWM within 
LinuxCNC's software.

But, now, rastering- that's genuinely complicated.  Like I say, at least 
2 modes here.  In either case I can't imagine how to do it with 
LinuxCNC's software.  In the case of the "analog raster mode" (using a 
high speed PWM and changing it rapidly), well I still don't get how 
you'd specify all the raster data.  You could use the Z to specify the 
power, but then it'll want to ramp into and out of pixels, which sounds 
pretty wrong.  e.g. with 100 DPI 50% gray, it would be:
G1 X0  Y0 Z0
G1 X0.05 Y0 Z1
G1 X0.10 Y0 Z0

And you'd end up with a sawtoothed path, instead of a square pixel.  
That's not quite right.  It would have to be:
G1 X0 Y0 Z0
G0 Z1
G1 X0.05 Y0
G0 Z0
G1 X0.10 Y0

Which might work, but it sure sounds awkward.

Re: [Emc-users] LinuxCNC as laser cutter?

[Sarah Armstrong]

Linuxcnc works fine for Laser cutting ,

Laser rasterising is a totally different matter , and needs to be looked at
from a different perspective
it also depends on how your laserbeam is switched , and the modulation type
used .
their is some limited information regarding rasterising on the Wiki Pages .

If you have problem with PWM signal generation there are plenty of cheap
micro controller development board available although protocols may be
worse. I guess it could be an idea to search m-codes for "professional"
laser cutters or maybe reuse codes usually used for spindle.

This might be doable with halstreamer and streamer, and might be used 
with a base-thread clocking rate.  The man pages do not indicate there 
would be a line length limit other than the size of the shared memory.

Would that offer fine enough detail, switching the laser on and off in 
base-thread time slices?

I can see that since the data would best be described as random, that it 
would need to be fetched in bit counts that would represent one full 
line scan per line since there would not be a unique EOL character to 
such data.

The laser would need to be turned off by the fifo empty, motion paused or 
moved to the next line while the fifo is being reloaded from the file as 
that would take an arbitrary amount of time.  Details of the startup 
acceleration I see as a positioning problem because you would want the 
laser carrier moving at full speed and at the true starting position of 
the image when the first bit was clocked out.  The inclusion of the 
enable bit mentioned in the man page for streamer would make some of the 
other timing requirements much easier to meet.

To work in both directions would be desirable as a retrace move would be 
a huge time waster, but inverting the order of the fifo clockout as 
opposed to pre-ordering as the data file was being generated seems like 
the better idea.  I can sure see a lot of cpu being used during the fifo 
reloading time at the end of each scanned line to accomplish this.  If 
clockout from whichever end of the fifo is needed, it seems the 
direction bit of the axis doing the scanning might be usable for that.

Details TBD of course. Size of the scanned image and its scaling to fit 
the image being cut would have to be preprocessor problems as any change 
in the size and scaling would require the source file to be regenerated.
I could also see the potential for 3D by clocking out a byte at a time 
which controlled the lasers power for that base-thread slice of time.  
The files size would of course be 8x the size of an on-off bitfile.  
That might, from available memory limits, constrain the size of the 
image being constructed as I can't imagine a mid line reload without 
artifacts in the image.

Food for the concept at least, I'll get me coat. :)

Cheers, Gene Heskett

That's Mach :-)

LinuxCNC turns on the output and starts the associated move at the same time.

However, for rastering you really want to be moving at constant speed
and "clock out" the image data depending on position.

Re: [Emc-users] A bit OT: DNC - NC file server from microcomputer?

[Nicklas Karlsson]

Simplest to understand would be one program automatically loaded on each USB 
stick. With a label on each USB stick a minimum of computer knowledge would be 
required.

[Emc-users] Animatics 5000 controller info, dropbox link this time.

[Gregg Eshelman]

Big Thanks to Chuck Searcy at Moog Animatics for digging through old backups to 
find this technical and programming information, and software for the 5000 
series servo controllers. One thing to note, small programs can be uploaded to 
the controller to have it run headless. Light Machines and Intelitek only used 
the DNC mode.

https://www.dropbox.com/s/8o87wzopl4yyjae/CD5XX6.zip?dl=0
Hopefully there's the info there to enable adding support to LCNC. Get that 
going and the value of PLM2000 mills will go up more since they won't have to 
be used with crusty old DOS software or have the control electronics replaced.
