    Also, the wing nuts work loose. Once, during a carve, one of them actually fell down on the the rubber belt. I didn't notice it until the carve was finished so I was just lucky that it didn't bind anything up. A lock nut behind the wing nuts solved the problem.

    I put lock nuts (regular nuts) on the other side of the tubes. Once the wing nuts were close, I spin the lock nuts up to the tubes and then tighten the wing nuts against them.

    The calibration needs to be run for each carve is the way I understand the instructions.

    I see that you also replaced the wing nuts with knobs. I like your solution. I'll give it a try.

    That's the way I understand it also but, I usually have the same calibration errors between each carving.

    Choose large diameter knobs so they are easy to "spin" up and down the threaded rod.
