Brenden,
we have been experiencing some stuttering of the step motors in various directions.
- Jog and use commands to move around with the motor turned off and see if the problem goes away.
- There are a number of reasons for the whatever you mean by "stuttering".
- If skipping try retuning the steppers / reduce accel and velocity settings
Before you do that make sure the machine axes are lubricated and move easily.
- Confirm that proper amp settings of the stepper drives are being used
- I know nothing about your "blue box" controller. You are on your owne for any problems associated with it and that includes the plug-in
if used. You can post the manuals for the the controller, drives etc. and maybe another user will help.
Experience has shown me to not waste time on Chinese stuff unless proper documentation
is available and is correct.
FWIW,
RICH
