loadrt remora-eth-3.0 PRU_base_freq=500000
Yep this fixed the problem (kind of)
Initially I still had a joint following error, so I played with the PGAIN a bit further.
x=80 y=300 z=80
Strange to say when the fault went away for one axis, it went away for all of them.
As always thenks for taking the time to reply.
PS is there some way to create some sort of online database that we could all put out faults with the fixes?
That way we could look up these thing & have a reply... "here are the top 5 solutions" type of thing.
Thanks

No, but that seems like a good idea.

are you using steppers without feedback?
i think recommended value of P is 1000 for 1000000ns servo thread (500 for 2000000) and ff=1
check the config example of this guy here:
forum.linuxcnc.org/49-basic-configuration/42385-config-steppers

hello, is it possible to make an nvem card work with qtplasmac?

Shouldnt be a problem, the THC would be an encoder module I think, but Im not sure what the plasma output would be, (PWM or analog?) and which is supported

Torch ON = digital output (through relay for safety)
ARC OK = digital in , optional as it can also be derived from arc voltage quite reliably
ARC Voltage = encoder input in counter/velocity mode, directly from Mesa THCAD if it can handle 5V, use a resistor for 3.3V input.

hello
I made some modifications to see if I can modify the graphical interface from axis to qtplasmac, I get an error message I have to modify other parameters?

yes I think that on this side it will not be too difficult for me, the most complicated thing will be to modify the ini file, hal.......

beauxnez, its probably going to be easier to setup qtplasmac first with the installer thing, then add remora to your qtplasmac config, instead of the other way around

Hello, I would like to add to this last topic about height control and the use of a QDC module or ENC software for the EC500 and EC300 boards, which, as I mentioned previously, the optocouplers that have the inputs on these boards do not allow the use of an encoder directly because they are too slow and lose pulses and the QDC module loses counting, so the hardware would have to be modified. I have made a design for a board to connect up to 4 encoders. I leave you the schematic and a 3D image of the encoder. of the board, obviously we would have to have the ENC_BOARD manufactured and that has an added cost, it would be great to find optocouplers fast enough that share the same footprint as the L246 used in the EC500/EC300 boards, I have not found them but if anyone has Anyone in mind to report, I have used RJ45 connectors thinking about crimping the same cable that the encoders of my motors have, however feel free to give ideas in this regard, the spaces located within the 4 DIPs are two 24->5V regulators/ 24->3V3 that I had before and will be assembled later, later I will see how I can share the project through EasyEDA or the *.json files on Github greetings
