I finally got my Hillbilly BOB/Mach3 retrofit going on my Bridgeport Series I Boss machine. I cut a part, and then after doing something else for a few minutes, I came back and pushed Page Up to get the spindle up. I only pressed it momentarily, but it must have decided that going up was a good thing, because it rapided right up to the top, made a bad noise, and I punched the Emstop button. I got everything reset, and tried pushing Page Down. No go - another bad noise (sounded like the belt slipping), and no movement. I took off the belt cover, and the belt looks ok. I was tempted to put an aluminum bar in there and try tapping the spindle pulley to turn it, but I might just make it worse. Any ideas on getting it unstuck? Is the ballscrew ruined?
Don't bother telling me that I should have checked the limit switches before I started using it. Obviously, I should have. After using the machine for years with the Boss controller, and never seeing such behavior, and never imagining that Mach3 would do such a thing... Any ideas on why it did that?
