Hello Thomas
I just gunk same machine, chimps and dirt everywhere ...
The previous owner knew everything except his machine cleaning and maintenance.
Now I have a big problem with the machine to move, I have damaged the tacho plug of the servo motor X axis. (with the pins of the truck)
All wires are pulled loose from the connector and now I do not know what color the wires which should be welded.
I think it's a 6 or 7 wires, black, gray, etc. (it is not the encoder!) On a connector male placed correctly with 4 screws.
Can you see what is the correct connection is.
Thanks in advance,
I will post a picture for clarification.
Greetings
