Stepper Motor Failure

Hi everyone,

Thanks for taking the time to read my post.

I have a 100mm x 60mm 100W CO2 laser machine and while doing certain jobs the laser head intermittently will not move along the X or Y axis, meaning it just cuts along the same line over and over again. The display shows the job is working fine.

When the failure occurs the error light on the X or Y stepper motor will come on.

Has anyone experienced this before or have any ideas?

I replaced the controller power supply and the stepper motors (https://www.oyostepper.com/) .

Thanks so much for all the replies
