Looks like a mesact bug.

In the mean time you could just copy/paste/renumber
the stepgen section from another axis to get it working.

Can you please try this later version of the linuxcnc image

I believe the screen issues are solved because the underlying Pi code had some fixes

Note, I only skipped the first 4 inputs pins so they are available for (up to 2)
MPGs.  If you do not have a MPG, starting a pin 1 (input 0) makes more sense.

How to configure pause/resume over pin 10 of parallel port?

Category: HAL

LinuxCNC does not really resume when the E-Stop button is released (unlocked).

You have to start the G-Code over again.

Can you also post the output of "ethercat pdos". It is likely the drives may not have all the PDOs you are referencing configured. Did you use the drive manufacturers software to configure them?

@Grotius,

I was suggesting you would need ESI support if you wanted to be able to avoid having to have special code for specific devices like linuxcnc-ethercat does. Ie, if you were wanting it to work something like twincat or other commercial products do.

@Endian,

Have you seen any issues on ethercat with the current position dropping to zero intermittently...noticed on the DRO? I've been attempting to use LCNC on a machine that has G1 acceleration of 1m/s and G0 acceleration of 3m/s (feed is 25-50m/min) and I keep getting following errors.

Minimum would probably be 1:10 for a Nema 23 or 34 motor, should be usable up to 1:30.
I would reference from the other side of the equation, 2-3 meters per minute of cut feed rate for 40A to 60A plasma, so for 150mm tube that would make 4 turns per minute roughly, easily done, but for 50mm tube that would be roughly 15 turns per minute.
The good thing with steppers in this case is more torque at lower speed, so start form 3 to 5 turns per minute and see what you can get on a high side.

my understanding so far was the THCAD-2 can be used but you have to add the HV resistor for ir to work and the THCAD-300 does not need the external resistor in my application;

That is correct.

In MesaCT I configured 6 axis on 7i95T and one on 7i78, but for that one there are no stepgens defined in .hal file:

# Mesa hardware step generators at every servo thread invocation, the step
# generator hardware is given a new velocity. Without feedback from the PID
# controller the hardware position would slowly drift because of clock speed and
# timing differences between LinuxCNC and the step generator hardware.
# The PID controller gets feedback from the actual (fractional) step position and

Nah, not my channel,

Yeah, it is probably Meister's channel, sorry for the mix up.

...got none of that online exposure, maybe one day but I doubt that. Same reason as yours, so little time for those sort of things :( 

I just had two friends in the shop, fixing 3 PC's, all the time they were screaming at me for not recording that and putting it online as they would like to watch that again and again! I am a pedantic p.o.s when i work with PC, so i always think that would be boring as hell ! :)

All the best to you & family. And be safe in that shop!!

Thank you very much. Been quite some time since i injured myself... aaah good times :)
