Hi I have had this cutter for several years and in that time I have run into this problem before. The carriage wont drop to make the cut. I have been lucky in the past and just replaced the Z axis chip...but not this time. I just for the first time grounded the unit with a wire and made sure the surface was clean from paint at that point.
Then install Z axis chip...no luck. If you shut down the cutter the blade will drop. when powering up the unit the blade will raise. I tried a test cut, again the blade wont drop to even make the test cut, and now two jobs pending I am in panic mode. I have read several posts about mother board and a new carriage, but what would be my next avenue to attack?
Thanks for those who reply to my cry for help.
