I am having a problem with one of my B machines and I don't know what to do to fix it.
During a carve it works fine, but if I push the STOP button or raise the clear cover the truck stops but the bit stays down in the carving area and does not raise above the level of the project. I have been physically raising the truck before I continue with the carve so that I don't break the bit. The same thing happened when the project finished carving and the machine shut off.
The machine has been upgraded with the Carvetite and rubber belts.

Thanks in advance for your thoughts and ideas on how to fix the problem.
Mike
