Hello! There are few more things to sort out with the plasma build.
First thing is that I am stuck at getting some pulses from THCAD board reflected in encoder rawcounts or whatever HAL pin value. Here is a picture of THCAD board in the cabinet: https://www.picpasteplus.com/v.php?i=0cbcca94b0 My first question - is the wiring correct? I mean, what is minimum wiring required? I have +5V and GND to power the THCAD and the third is FOUT+, all three wires connected to "encoder" on 7i96 - 5V and GND to the respective pins, FOUT+ to A. Here is the 7i96 board: https://www.picpasteplus.com/v.php?i=d238f584b4 Am I missing something? I think that the jumpers are correct for single-ended pulse signal. And I have set it in HAL for counter_mode = 1. Second thing is that I have to use an existing plasma source that they already have - "Telwin enterprise plasma 160 hf", which is meant for manual cutting. So there are 2 challenges - get the plasma voltage and arc-ok signal. Does anybody happen to know, if the controller board of this machine has dedicated outputs for these 2 things? I have connected 2 wires to plasma ground and torch cables respectively and connected them to THCAD board. I hope that it would work and not cause too much of EMF noise. Cable is shielded, shield is connected to ground at a single point with all the other cable shields. How do I obtain arc-ok signal? Can I do it in HAL by watching plasma voltage and trying to assume that it is ok, when voltage drops below some preset treshold?
