Ray X axis judder

Hi all

Just switched on the ray (20w) and using lightburn.

Not quite sure what I’m doing yet as its all new to me but did manage to home the module (back left) and make it move around a bit.
I made a shape on the LB screen and pressed start, and the module moved from left to right side with a bit of a juddering noise on the x axis as it travelled.

It seemed smooth and quiet enough in other little moves and Homing so I’m wondering if it could be a speed issue.

Sorry I dont have any settings to post as I had to leave it and go elsewhere. I thouht I’d just ask the question incase its a common or recognised issue.
