Hello all, I have a knockoff brand bed mill (Long Chang Machinery RB-1) with a Fanuc 0m-a CNC.
Up until last week when I finished manually facing off a piece of aluminum, I stopped the spindle like I always do... Then I went to turn it back on (MDI mode -> spindle cw button), and nothing.
Lights don't change, diagnostics bits pick up the button presses, but they don't do anything.
Any calls to m3/m4 just hang the program and MDI until you hit reset.
I'm assuming there's a limit or something that needs to be met, but there aren't any on the spindle (only the typical axis switches).
I've checked all the relays and wires, but I don't have any schematics for this thing either.
Anyone have any ideas? I don't need the machine right now, but I'm sure I will soon.
Edit:
Oh and its just a basic spindle, not a servo driven unit, so the CNC only controls a reversing contactor.
