I'm having similar difficulties finding any information about this lathe.
unfortunately one motor is working in one direction and manual mode and I get no other movement at all.
I cannot find any documentation or information anywhere on the Internet about the slave or schematics or hints on how to check see which sections broken.
extremely frustrating because I think the only answer is going to be that the whole thing needs to be gutted and a new driver board installed.
Unfortunately I will lose the ability to use the manual interface that's built into the cabinet as well as view the LCD display built into Cabinet.
it by chance anyone has any information on the Lathe before I destroy it by ripping out all the electronics,please let me know.
