hi i have a 3 axis ebay controller and the problem i have is iam using the spindle relay to turn the gun on/off, ive tapped into the two wires off the plasma gun but when the relay fires the gun the control board trips a limit for the e/stop. even if i disable the e/stop in the input setting its still doing it. and ive even tryed running a extra relay but it still trips the control board. the relay runs a 12v bulb ok wired to a power supply so i no the relay is working ok. i think its down to the feedback off the gun.
anyone no if it is the feed back off the gun or got any ideas how i can stop the feedback off the gun.
thanks adam
