OK,I am sure this has happened to someone...

When I am working on a project and my machine is going through the calibrations (Insert bit, measure, insert next bit measure....) and it goes to work. Here is where I run into problems.

After is gets done with an operation, and requests the next bit, I insert it, the machine makes sure it is the correct bit, then it gets ready to carve/cut/route (whatever) however, sometimes the cut motor wont start up. The bit goes to the desired location, and starts dragging on the wood until I get a "Z axis stall' by then the piece is usually damaged, and I cant back up a step or two and start over again... so wasted piece.

Has this ever happened to anybody, where the cut motor fails to start again after a bit change.

I now watch closely and if the motor does not start, I lift open the cover and close it again, which usually starts the motor up.

Do I have a bad sensor or is this a normal glitch for a machine that has multiple sensors calibrated so close in tolerance?

Thanks,

Woody

Check your motor brushes. May be wore out or stuck.

Your problem is probably that right cut motor cover switch. Maybe you have a dust collector holding the cover up a little?

I will check, I do have a dust collector and ocassionally the grounding wire rests against the cover, thanks,
