General Mach Discussion / Step pins being changed by Mach3, motors stop
« on: June 29, 2015, 05:01:30 PM »
Hi,
I have mach3 tied to a bladerunner system (trying) to control my plasma machine. I set the STEP pins in the Pins and Ports menu, jog the machine for about 30 seconds, and then (usually) the x axis stops working. Go back to the Pins and ports menu > motor outputs and the step pin for whatever motor is not working (usually the x) is changed to a random number. In most cases it is 0, but at times all of the motors change and the machine stops responding.
The machine is a Dell Optiplex 780 connected to the bladerunner via LPT1 and onboard serial. I was running on windows xp 32 bit, sp3, I tried switching to Win 7, the problem persisted.
Any ideas?
