General Mach Discussion / DIY plasma no movement after first arc
« on: January 17, 2018, 02:57:31 PM »
Hello , looking for some help with an issue with my plasma table. I had everything working, all axis were jogging in the right direction, Relay to fire the plasma was working. Cut a whole bunch of air patterns making sure that there would be as few surprises as possible when I fired up the plasma torch for the first time. Well that didn't work... At the first arc all motion stopped, I'm guessing it was a HF problem from the older Easab I was trying to use. I have since acquired a new Thermal dynamics, and redid all the grounding. So I should be good if I ever get this thing going.
Mach (licenced) seems to be working, the DRO's change with the jog buttons or when I run some code. The E stop works. I can see the limit switches operate on the diagnostics page and I can see the relay for the plasma working with the button so the connection to the computer is working,I think. I've changed the BOB (CNC4PC C-10), no change. I replaced one of the stepper drivers(CWD230), no change, checked the serial cable for continuity, all good, I went over all the wire connections and did not find anything wrong. I'm running out of things to try. I would appreciate any advice. Thanks for any replies
