I am starting to hear an audible click/jerk noise when the machine is moving in the Y axis, but only when the spindle is powered on. At first it was difficult to hear when the machine was running a program. However, the machine nearly crashed during a very light DOC during an adaptive clearing toolpath.
The Z axis began to slowly drop into my fixture as it traveled in the Y direction, as if it was ramping down but it should not be. Luckily I stopped the program in time.
Has anyone experienced this? This only happens when traveling in the Y and only when the spindle is powered.
Does the Z axis DRO move along with the corresponding Z movement?
i wonder if there’s some crosstalk going on. Check your wires, see if Y and Z are right next to each other. I’d start with the wiring in the control box since the outputs to the servos aren’t logic level. If so try moving them apart and seeing if that has any effect on your issue.
