I recently acquired a Bridgeport CNC Series 1 Servo machine that at some point had been converted from Boss controls to Fagor (model 800M) back in the day. The spindle had also been converted to run on a VFD on 110v. The machine runs in all axis currently, but the Fagor control is a very old control that doesn't run on G code. As such, I am looking to do a retrofit to a Mach 3 based system.
I have used Mach 3 on 3 other machines in the past but they have been stepper based machines and much smaller (read as desktop machines).
Anyway, after a lot of research, I am thinking about a conversion setup that looks like the following:
CNC4PC Ethernet SmoothStepper
CNC4PC C32 BOB
CNC4PC C34DG (if using DG4S driver)
DG4S-016035 Servo Drivers (or maybe a Viper)
Continue to use the existing VFD for the spindle
Continue to use the existing eStop and limit switches
I will also need to add a 5 and 12v power supply. I am thinking that I can use the current power supply for the motors but will have to see about that. All of the rest of the existing cabling and controls would be removed. The new components would be loaded into the existing rear housing.
I will also use the existing Servos which are Servo Dynamics MTS30M-38 no. S23706 with an rpm of 1400 and a volt of 47 from SEM.
Your thoughts and input would be greatly appreciated before I plunk down cold hard cash on this retrofit.
