I have just brought home a Daewoo Puma 6 lathe. It has the Fanuc OT control. It was running parts at a local shop when I bought it.
This machine was nasty, so I took off the door and front cabinet, and steam cleaned it. Then when I turned it on in the shop for the first time it seemed to work fine. I ran the spindle, changed gears, changed tools, ran tailstock in and out. ect. Then I shut off the power and went to eat dinner. Later that evening I came back out to play with it and now the spindle drive will not light up. The other boards do, just not the spindle drive LEDs. when I attempt to power the front operators panel it gives an 04 code on the operators panel alarm readout. There are 3 small automotive type glass fuses on the board underneath this top spindle drive board and they check out OK on the volt meter.
The Spindle Drive board is # A06B-6059-H212
Any Ideas ???????
