I have an Industrial CNC Pro Apprentice 4 x 4 machine and am in need of a wire schematic for the BOB or advice on how to install a new BOB when I have no idea how the current BOB is wired. The wires to my current BOB are either red or black and nothing is labeled. I can't find any info online and I can't even find a BOB that matches what is in my machine. I have no paperwork or manuals on this machine and support from the company is nonexistent. I am not very savvy on this part of the CNC, I can tell you that my BOB uses a 25pin parallel cable and I am running Mach3. I can post a picture of my BOB if that will help. Any advice or direction as to who to contact would be appreciated. I want to wire in a triple edge finder made by Bill Griggs and a secondary Z touch off plate but not knowing what pins to connect to is making things difficult for an amateur.
Thanks Mark
