Thanks for all your input, I greatly appreciate it. I finally caught up with it. I got to the Y-scale and it definitely needed cleaning, but it did not remove the error message. I also measured the voltages on the power supply board beneath the keyboard and they are all within +/- 5%, so that should be fine too. The voltage on the memory battery connectors is 3.5V when the machine is on and the battery removed. The memory works just fine holding all the constants.
All right, here's an update and new question: While pushing the ready button, error indicator displays "36", which according to the schematic (see pic) means either a problem with a Temperature sensor on an Axis Motor or with the 24V?
While keeping the ready button down I could measure 25.7V between terminal 302 and 324. I've noticed also a very faint snaring sound on the Y-axis motor that gets louder the longer the ready button is held down. I measured again on the NC controller power supply and do get the 24V, that do not flicker a bit between pushing the ready button and releasing it. Since the Y01 error message shows up on the monitor, my best guess right now is that there is something going on with the Y-axis motor. Any opinions out there?
By the way, I found three switches in the upper right corner of the control board. The top is to apply/release the Y-axis brake, the second one is for the machine constants memory and the third one for check run. Any ideas what those are good for?.
