Hi Chris, since the original topic was for the power supply I didn't mention any details about the machine. This is a Daewoo Puma 12L turning center with a Fanuc OT-C control. The machine is from 1996. As for the power supply, they are very hard to debug if you don’t have a > schematic. But what about replacing it entirely? > That would be a way to stick with the original control a little longer until something more critical fails, but the problem is, this PSU has a connector that goes directly on the motherboard of the CNC. Most of the pins are grounded but there are several others that I don't really know what they do. I can't find any schematic to see what each pin does, and since I can't power up the PSU I can't measure them either. These PSUs are like 1500 USD and up brand new (this is nuts if you ask me, we're talking about a switching PSU), there are cheaper used ones on Aliexpress but I'm not sure about them. And of course, this is a 1996 machine, something eventually will fill again, so I'm seriously considering the LCNC conversion right now. If I can solve the servo motors issue this should take 2 weeks maximum. > Good motors are always expensive. But encoders have gotten cheap and easy > to use. The last one I bout was an AS5048.
