The blue cable looks like an Ethernet cable and goes to female plug below parallel port in this picture the two big switches above one activates laser one motors
I don't know how machine was controlled originally there is another board underneath brake out board the coordinates change when I move machine manually and there are some flickering LEDs on board behind bob when mach3 try's to move machine motors.
I'm starting to think that this is some kind of dedicated system and I will need new Bob and start from there but I would really like to get it moving plus previous comments lead my to believe not all bobs will work with my drivers.
For now there are more questions than answers.
Thank you for your patience
