x axis don't go no more
« on: August 22, 2009, 07:35:58 PM »
I have a four axis setup on my router, running G320's with a Campbell board. Last week when I fired up a program, the gantry moved into position across both x and y axis,  then router promptly started cutting in only one dimension- Y.  For some reason after moving into position, the x axis quit. Did all the gyrations of trouble shooting by swapping cables, popped in a spare 320 controller, etc. Still no X movement.
Shows motion on Mach 3 display, DRO counts off, etc, but aside from the servo on the x axis just locking into position, there's nothing happening. Yes the Gecko shows fault, when I unhook the drive voltage to the motors and I move the gantry on it's rack and pinion. The controller sees the motor, but can't make it move.
What makes me mental, is that a few days later without doing anything, I fire up the cnc machine and everything works perfectly...until today that is. The x axis quit again, and that's after moving to its start position.
Ideas? Anyone? Anyone?
