New Rotary Jig. Calibration error.

I plan to use one machine solely for that job.

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.

I am having the same issue with my machine that is only 6 months new. Head pressure is normal 80 lbs on a new scale.All alignment marks line up perfectly, I ran the calibration 15 consecutive times with the same result, calibration error _calibration out of range!What next
