Finally looking at replacing the Linux based Servo3IO and CPU10 DC servo drive in my Ajax DM45NC mill with something like the Acorn. I looked at other controls but am pretty comfortable with the Centroid software so why learn something new? I'm hoping to get as much pre-wired as I can before cleaning out the cabinet. The power connections for the servos are obvious and I plan on keeping the existing servo power supply. I have three of the 150 volt, 20 amp Machdrive BRC drivers coming to drive the existing servos. I have not ordered the Acorn board yet - still making sure this is the route I want to go. I need to figure out the brake on the Z axis and I'd like to make a panel that the three 9 pin sub d cables simply plug into instead of cutting them off and rewiring them to the DC Servo drivers. Does anyone happen to have the pinout of the 9 pin encoder cables that plug into the bracket connected to the CPU10 board in the PC?
