Hello,
We have a QT20 lathe, 1995, great shape, we do not use it much. Warming up the machine, on its own, parts catcher starts going up and down, turret unclamps, control rolls several screens. It happens in about 10 minutes after startup, consistently. I can shut the machine down, restart and everything is ok so probably not the ladder.
Mazak and Mitsubishi stumped, I re-seated all the boards, undid all the connectors on the control panel, checked voltage, 200v, 100v, 24v. At the end of the day I noticed the fan sucking air out of the drive area was off, I spun it and it went on but a little slow seemed like everything was ok. I ordered a new one from McMaster but as I turned the machine back on it did it again but the fan was blowing strong, I am thinking the fan was over-amping and screwing up the IO board? I ran out of time and I was just wondering if anyone else ever had this happen before,
