bandit controller retrofit

Funny thing: the driver is marked "O1D DRIVER", which looks like "Old Driver".

Do the servos move when you attempt to jog them with the bandit?

Whoa! So many wires!

So confusing!

Such a pity they didn't helpfully colour code the wires a bit or have a schemetic sticker.

I'd probably just scrap the drivers and electronics, old electronics are often really poorly made and are generally very power and space inefficient.

New drivers are so cheap, I don't really see any compelling reason to use those old ones.

If that's not your thing, I probably recommend removing all but 1 driver and then only testing that.

What is the fourth board near the power plug?

Some power filter board?

EDIT: When I say "electronics", I mean circuit boards and that sort of thing.

Old induction motors and transformers are just fine.

What's the line filter for?

What output voltage is the transformer?

Yes that's really confusing, the cable from the motor has 8 wires, I suspected that it might be a stepper,but isn't it. Yes, that's the only way I can move the axes, in ``jog'' mode.

that I know that the drivers are not expensive, or in that case I would have to install other motors, because there is no driver for such motors with an unknown type and with 8 wires.

So the servos and drivers work?

Good.

Servo wiring hypothesis:
Wye or Delta brushless motor (4 or 3 wires) with an optical interruptor (2 wires for LED power, 2 for photoresistor (or phototransistor))

Or something like that.

New motors are probably lower quality.

Nowadays, weight is a big concern.

Steel is not so cheap, and since everything is shipped from the other side of the world, a heavier motor means a greater shipping cost.

I think that's why induction motors and big, heavy thansformers are not widely used nowadays, they are very expensive to transport.

But motor drivers are light, so they are efficiency and cost optimised.

that's right, on my market you can find a cheap servo set from 1 kw motor + driver for 200 euros., I have to check first if it has backlash , I mean ballscrews

Which wires connect the control and drivers?

Remember: experiment on only 1 drive to make stuff simpler.

Make a binary counter circuit (a 4520B in 8-bit config and 8 LEDs connected to one counter output each can help you detect pulses (motor move pulses are too fast to see or detect, you have to slo them down with a counter too see them)) on a breadboard or something.

See if it detects a clock signal.

Those ribbon cables are probably parallel data lines(yay! Shift-register time!)
