Hey KnotAproblem,

have you ensured that your machine is accurately rectangular (“squared”) and coplanar (“not twisted”)?

Also Onefinity provides a help document which deals with many kinds of blocking of an axis:

I would check all points one by one to see why your carriage moves so strangely.

Besides this, there are three causes that are not mentioned in the document above:

  1. Should your machine not be properly rectangular (“squared”), the Y movement can stutter or even block.
  2. And the second possible cause not mentioned in the document above is: This mysterious issue some time ago.
  3. Electromagnetic interference (EMI), as e.g. mentioned here.
