Juddering Y axis

[dazza]

My next job then, is to get the machine unbolted from the bench and slacken, jiggle, check and retighten the rail mountings. I'll probably take out the Y motor and check the feel of the Y slide on the rails.

first just disconnect the ballnut mount from the back of the plate,that will free up your z without removeing motors or screw,then slide left to right,if somethings not aligned or theres bother with the bearings you'll feel it tighten as you go,.
