New here, just bought a 2000 MiniMill for use in a home shop.

One of the issues I ran into is an issue with the door interlock circuit. The control reports door open even though the circuit is good all the way to the IO board (so the switch itself and wire seem good). I can run the machine by using the door override setting (51) but have to do that each power-up.

I am an EE with computer design experience, scopes, etc. Does anyone know where I can find the schematic for the IO board?


Side issue: There are no o9xxx programs on the machine (specifically the QC file, 09999, and the spindle warmup routine, etc.). I suspect someone accidently cleared these when clearing the machine when they sold it. Is there a place I can get a copy of all the o9xxx programs I should have?


BTW: Anyone else in/neat Tampa operating a MiniMill?
