Boxford 4th axis

[magicniner]

Do you have a multi-meter? If so you can disconnect another stepper and meter out the wiring to find out which pins go to which motor wires.

As a first step, I'd be tracing the wires to see where they go inside the control box.

I'd guess only 4 of the wires are for the stepper, with the others being inputs for sensors/switches, and/or outputs for controlling locks/actuators.

Hopefully by tracing where the wires go, you'll be able to work out what they do.

I'd guess only 4 of the wires are for the stepper.

Steppers come in 4, 6 and 8 wire flavours, not just 4, it is possible to connect a 4-wire driver to 6 and 8 wire steppers by externally connecting the circuits to a 4-wire configuration, but if you have a 6 or 8 wire driver you cannot use a 4 wire stepper

Which is why I said to physically trace the wires inside the control box. The stepper driver wires should all connect in the same area, possibly to an individual driver, which means you know exactly what wires power the stepper motor.
Then it just leaves the other individual wires, which by tracing, will hopefully connect to a terminal with some form of name to work out what they do.

I would very much doubt that all 8 wires are solely for powering a stepper motor, given Boxford typically only use 4 wire drivers.

Boxford typically only use 4 wire drivers.

That is really useful information.

Sound advice, been into it today, 8 wires in the socket
2 red singles 2 orange singles.
1 multicore red blue green yellow.
traced back to 2 boards
Ok up til there . . . . I can meter out one of the other steppers to work out the wiring, but I haven't a clue what the red and orange ones do - they are a bigger section (18swg) than the multicores. Could they be for power ? Galloping ahead, I have never seen one of the Boxford 4th axis' in the flesh, does anyone know if they are direct drive or reduction ?

just seen a Boxford 4th axis underneath view - right angle drive with proxi switch, all wires black except earth, hmmm

All black with an earth sounds like CY cable and the blacks are usually numbered if you can get a better look.
