I recently bought a 2006 Hardinge GS-200 with a fanuc oi-tc control, and I'm tryin to get the C axis up and running. I see M45, M19, and M91 on different sites all saying that it engages c axis mode, but none of them work. The control just pauses at M45 and M91, the only one that has done anything is M19, but it just looks like a spindle orient command.
If I command a:
G28 C0
or a
G00 H0,
the control gives me a "C AXIS COMMANDED IN SPINDLE MODE". Could the code possibly have been changed in parameters? If so, how would I find and change it?
