Crossfire Pro not cutting circles properly

Having troubles with my Cross Fire pro not cutting circles correctly. The circles are only 1.5 inches in diameter, it’s cutting them more like an oval shape
. Any help much appreciated Thanks

Leadscrew couplers are probably slipping.


Switch out the 3 lead screw couplers with these. I got tired of dealing with egg shaped circles and tightening and tightening them so I went with these.


Did they come with 4 clamping screws or 2? Looking at the only review from June of this year it looks like they sent out a 2 screw version instead of a 4.

Each coupler that I purchased came with 4 screws. 2 on one side for the motor and 2 on the other side for the lead screw.
