GTXL Servo Jitter & Drift
Having trouble with our trusty old GTXL...
Just started happening today, so far about 10 times, for no apparent reason.
Y axis occasionally 'jitters' during cutting, at which time it loses its position control, so that it becomes several mm or up to several cm out of position in the Y axis.
No error message on the screen, it just keeps cutting as if nothing was going wrong.
Also, sometimes when the cutting head should be stationary, it jitters and 'drifts' out of position, at which time we have to hit the e-stop to stop the movement.
We tried swapping in a new Y-axis motor, no luck. Also checked all connectors and wires, all looking good.
Thanks in advance for any advice!
