BAD vibrations!

Thanks for helping me before, another problem has developed.

I use an atomstack 20 pro with lightburn and win 11.

Randomly during a cut, my laser stops and vibrates. This may last seconds or minutes. then the vibration stops and everything is normal and the laser starts moving again, there is no set time between events, happens without warning. It also upsets the framing. This tends to fhappens for E-W movement. If I move N-S quiet as a mouse, but E=W, terrible

I tried different computers, different usb cables, different usb comms, have tightened the runners

Would really appreciate some advice.

Seems like something maybe binding on your X axis.

Thanks for suggestion, will have a look at that, something is clearly affecting e-w but not n-s movement
