Bryan, I have tracked down the issue and implemented some workarounds. The Z axis stepper does seem to be locking during process as it should but the issue is apparent when jogging the z-axis small increments upward. On close inspection the spindle does slide back down sometimes particularly closer to Z0. This situation occurs as the stepper is not instructed to hold when jogging and the issue is exasperated as the software indicates that the spindle has risen the required amount.
I have run several programs with this in mind and have not had an incorrect cut depth. I will investigate further a mechanical counterweight to fully overcome this issue.
