3. HM5-4EH - 4 axis 100 MHz PWM clock
Modified so basic clock for PWM and interrupt rate is 100 MHz
ID/REV reads AA020004 (low half is # of axis), MCLK reads 100 MHz
I can send the source and bit files tommorow. (where?)
Peter, if the files are not too large (5Mb) you can email me the
Yes, that is true :-), But if you make some ~1000 microsteps on a
stepper, you will start to notice that no more is a step in
question, but rather an increase in torque, or pressure and that the
accuracy dropped down in load conditions... So, in smaller machines,
where only slow speeds are

Voltage doesn't mean much to a servo motor. Current is what
Dear fellow EMC users and developers,
Several months ago I asked a question about remote control of EMC. I
received many excellent responses - thank you all.
As the system architecture progresses, it has become clear (or clearer)
that what I need is the ability run EMC2 from within a
Why python? If it is because you already know python, then I'd suggest you
start by examining AXIS. My guess is that everything you need is in there.

Jeff made a program to do the DRO part of that.
It's here: http://emergent.unpy.net/index.cgi-files/sandbox/dro.py
It may be easier to start there instead of with Axis. One thing to
think about is whether you want the buttons to actually tell emc that
it's at zero, or if you just want it to
I have EMC2 running on a three axis Mill. It runs great however
whenever I start up the HMI program an error is reported. It says that
I should check dmeg. I have included a copy of the dmesg output. I'm
sure I need to change the configuration of RTAI but I don't have the
slightest idea of what
I've just put an example program, called jdi (just do it) on the
AXIS blog:
jdi.py is an example of controlling emc with a simple Python program
that sends NML messages. It will turn off estop, turn the machine on,
enter AUTO mode, open the named file, and then run it.

Glenn,
See if this is of any value. I haven't checked the released version lately,
so this may only be in head at this time. But do a CVS check out and compile
of 'HEAD'. In there you will find a program called emcrsh (in bin). It
basically supports the same functions as emcsh only over a telnet
This problem is being solved by increasing the jitter tolerance from
+-5% to +-10%, it will be in the next release of EMC.
(see my ~20-mails long conversation on this topic in emc-developers)
The message is only a warning, not a catastrophic error, no need to be scared...

Thanks,
I'll look into these items.

Greetings.
I was looking through my collection of parts and pieces and found an USB to parallelport adapter (for a printer). I was wondering if it would be possible to use it to controlrelays etc with Hal. I am sure that a driver would need to be coded and a hal module ( unfortunately a little
