The only real problem with the Bandit is keeping it running, especially if it's your 'one and only' and you'd like to get something done every day. Lots of tarnishing edge connectors are the main culprit, it seems like 'up time' might vary from week to a month before it starts to act up. A regular maintenance seems to involve powering off completely, lifting the card cage, slide all the cards on and off the backplane a couple of times, same with connectors on the wiring harness.
The Bandit will do DNC. I do not recall off the top of my head what the maximum baud rate was for DNC, but 1200 seems like the right figure. This is slower than the maximum comm speed, which I believe was 4800 baud.
This means that short segment 3d or 2d programs will run at a limited feedrate, no matter what F you command, it might be hard pressed to average 20 ipm, more often, less than that. That is not out of line for an old cnc that might only achieve 100 ipm rapids.
Its a good old control to learn on, but it is bare nuts to operate, so you are starting on square one because the control is built assuming you are an expert programmer, and thoroughly understand the implications of using G92 to set the program reference point on the machine.
