I have started pulling the Bridgeport apart and have the step-head and the drives off. I have partailly disassemblied one of the drives and have determined that I will need to put in a new encoder pn the servos. I ordered 3 AMT102-V encoders and 3 Whale DC servo drives, plus breakout boards.
I need to source 3 220uH 11amp inductors to ensure that the drives will function correctly. I will be checking the Hamill control box to see if I can scavenge both the inductors and what power supplies are built-in. I will need an 80VDC, 30A supply.
Pictures will follow shortly.
