They are fun little lathes & well made, dovetail bed with recirculating ball screws.
I kept the manual controls (motor, dir, jog, override etc...) as they are more convenient than pressing the PC keys.
My main complaint is that the system has very poor earthing, it also runs hot so I added a small fan which actually removes the hot air from the enclosure !!
Opto-isolating is mandatory with high voltage and bad earthing !!!
The GE motor drive also has a 10V analogue feedback signal, but sensing the spindle optos is easy.
