I’m having a location problems on my X axis. The problem has creeped in slowly, but continues to happen more, and more often. I’m running Artcam Pro 2008 —> MACH3 —> Gecko G540—> XZero Viper X2 with KL23H286-20-8B motors. I’ve run this setup for 4 or 5 years with no problems. I do a lot of highly detailed inlay work, so location is critical. I’m loosing location on the X axis only. It seems to be in increments of approx .024”. Most of the time when it happens, the machine is in the middle of a multiple step-down cycle. It will correctly mill a portion of the pocket, then when it returns to the safe Z to start the next stepdown, it shifts about .024” on the X axis, and continues the pocket. Where & when the problem creeps in seems completely random. If I re-run the same program, the error does not come up in the same spot, or doesn’t come up at all, so that rules out a corrupt file.
I have slowed the motor velocity in Mach3 config, but that hasn’t made any difference. Am I looking at a bad motor, or could it be something else?… Thanks
