I bought a compact machine for the home shop from a guy in Kansas. When I drove up to inspect it he had it un-wired and moved into the corner for space. He had a recent video of the machine running properly without issue.
Machine is a 1985 Takisawa TC-2, with a Fanuc 3T-C control.
After i got the machine home, wired and fired, Everything seems to work(chuck, tailstock, lube, coolant, spindle, X&Z axes), but no matter what I cannot get the control to execute code in MDI or AUTO. Hitting the cycle start button just illuminates a "?" light on the control panel, and the machine does nothing. In the manual the "?" light is labeled "operation error". It will not operate with any of my code or the programs left on the machine. The screen shows no alarms.
Its acting like a door switch or lube switch isn't happy. If this machine has either, I cant find them.
I do not have a ladder diagram or wiring schematic for this machine. I only have the base operator manual and the basic Fanuc programming manual. I also found the a fanuc maintenance manual in pdf.
Ive spent some time in the diagnostic screen, although i don't really know what each diag number stands for. I actuated all the controls on the panel while looking though the diag screens trying to spot a changes in bits. As far as I can tell, it seems that all the controls work properly.
I have already re-seated all the connections on the main board, with no change. I changed the batteries even though there was no battery alarm.
Anything else I should check? I feel like this may a lost cause without a ladder, but I'm hoping someone here can shed some light for me.
