Too bad... a missing power supply would have explained all the symptoms. I assume they are still the same. Just to clarify, can you move the table and z axis before you try to run the spindle? and are any other LEDs lit? Just trying to see what might be deliberate for safety and what is an actual error. AND there's a BIG "Uhoh".... looking at page 6, there are all the spindle control signals. They come from the J1 connector and go to the J35. The J35, I assume, goes to the spindle speed controller, which the sheets say is an EMS Speed controller for 45K Spindle. Mine is a 5K machine so I can't help you with that one. The "Uhoh" is because J1 is from that Nextmove Card in the computer. That's a $1000 board if you can find it. It was the reason my machine originally crashed before I bought it. You could try swapping the computer with one of the working units, but the risk is taking out a working card if whatever caused the original card to die is still present. I wouldn't do it. I could still be something on the control board but the Nextmove card is notorious for dying.
Anyway, its hard to say what is the issue. Someone with a 45K might have a way to test the EMS speed controller.
