Hey guys! I picked up this wonderful little CNC lathe! I want to protect the original electronics as much as possible, so before I do any conversion, since this can easily be controlled by LinuxCNC already, ( see: https://www.forum.linuxcnc.org/30-cn...nless?start=20 ) I want to be extra careful not to damage the original boards since they can be used and my lathe works perfectly : )

Are there any good opto isolated pci parallel port cards or some kind of opto isolated adapters I should look for? A quick search did not reveal too much.



Please forgive the picture being in the wrong orientation, for some reason the forum rotated it that way despite it being correct on my PC.



A lot of the work has already been done on the setup by others except I don't see anything about the automatic tool changer. I'll cross that bridge when I get there.
