    When my y axis moves in the positive direction I get a lot of wobble and it is pretty loud.  I was going to order new bearings,  but I thought I would check here first.  Maybe an alignment issue.  I tightened the zip ties pretty tight when I built the machine.  Maybe too tight?

    Sounds like you have a loose wire or poor connection on one of them. Or you are trying to move it too fast, no more than 100mm/s just to make sure.

    I am only running 40mm/s max. I will check the wiring,  but I suspect a bearing is at least part of the problem.

    Then loose connection, if one wire is loose it is only running both steppers on 1 of 2 coils.

    You were right.  I reseated the stepper cables in the ramps board and it is smooth now.  Thanks for saving me from tearing apart the machine!
