Hello, gentlemen!
I am trying to load 3-phase pwmgens on 7i43 for 7i39, but I receive error.
With this one EMC loads correctly:
CONFIG="firmware=hm2/7i43-4/SVST4_4_7I39.BIT num_encoders=3
num_pwmgens=3 num_stepgens=2"
Note that this line requests single-phase pwm generators.
So according to thi

I'm writing a user-space program to manage spindle speed on a machine
with a VFD for the motor, and drive ratios set by belt and gear changes.
From available HAL signals I would like to determine whether a spindle
speed change is due to the speed override slider in axis, or due to a

This doesn't answer your question, but are you aware that there are
realtime modules available to d
I was looking at this encoder, http://www.usdigital.com/products/e2#description
It says:
Tracks from 0 to 100,000 cycles/sec
32 to 1250 cycles per revolution (CPR)
128 to 5000 pulses per revolution (PPR)
I don't understand the difference between CPR and PPR, I am thinking it has
something to do

Hi EMC users,
I have EMC running on an old pc, latency number about 25000. I got an
occasional real time error with latency number set at 22000.
I drew a part in CamBam, generated some g-code and cut a part. The part
looked right but the caliper says every dimension cut a little small. A

What is the range of deviances? What I mean, how consistent is the
deviance in dimensions? Is it very close in all directions, is the
error along one of the joints or is it completely rando
