Hi everyone,

As it turns out, it was the grblShield. I ordered another one last week with the Shapeoko modification from Synthetos, LLC, and it came yesterday. I replace the old one with the new one just now and everything is now working. Just want to let everyone know in case anyone else run into this situation again. More than likely it was something I did to the old board to cause it to misbehave!

Thanks everyone for your help and suggestions.
John.

I am glad you found the problem and am sorry you had the problem. If you return the old board we'll give you a refund for it. I'd like to figure out what went wrong - so perhaps we can have an offine discussion to try to narrow that down.

Hello,

I had the same problem.

I know how I caused the problem though. I was half asleep and was hitting the +Z button instead of -Z button and kept driving my motor into the ground. It must've sent some big surge backwards or something and damaged that terminal. Bc i now have a confused Z axis.

This happened to me as well, turned out it was a loose wire on the z axis stepper. Fixed.
