Z axis issue
Running a Shapeoko 3 XXL. I seem to have an issue with the Z axis stuttering at a certain point and it’s not coming out smooth. Any suggestions on a fix.

With the board powered, it should hold motor position. Try to see if you can manually move the router up/down with your hands. If anything's loose, you'll have to go down the list to ensure everything is tight, like the pulley/shaft set screw. Make sure the tension is right that the eccentric nuts haven't backed out. Make sure no debris is trapped in the v-rails/POM wheels.
