NVUM non correct g-code execution

Post by Term1nUS » Mon Jul 23, 2018 10:46 am

Dear Sirs,
We bought NVUM controller from your company and when we mounted and tested it we found that there are non correct g-code executions in MACH3.
For example G-code:

N060 G1 Y200 ; MOVE TO X200
N070 M3 ; FIRE PLASMA TORCH
...
N060 G1 X200 ; MOVE TO X200
N070 M5 ; SHUT DOWN PLASMA TORCH

So, we have next situation:
Machine starting to move to Y200, then I see that MACH3 moves to next line and fires the torch. But movement still remains. It is have place in next step, torch moving to X200, but after start moving it skips to next line in G-code window and shuts plasma down. Movement with shut plasma torch is going on.

What can it be? It looks like MACH3 or NVUM I don't know can't count step/dir impulses correct. Frequencies were examined from 25kHz to 100kHz. The results are the same. Or it reacts on M macroses. With @dumb@ break board all works fine.

Help please. I have found one more case with common sympthoms in internet, and this man have problem with firing/shutting laser before movement stops. And he also use NVUM controller.

Thanks for your attention.

Yours, Andrii Romanovskyi.
