The wiring diagram will make the job easy, thanks. I've started stripping the CNC of its harness and am working on the mounting board. I thought I'd mount all components proud off the surface by some 5 mm to allow maximum airflow around the objects ... should help with cooling on hot days.

I have a 5 amp trip fuse, good condition and works with a range of DC voltages, can use that instead of buying a new one.

The supplier for the BOB does not have the female connectors and none are supplied with the BOB, so I'll follow your suggestion and use the decoder cable.

Thanks for the animation, explains a lot

Is your 5 amp trip fuse suitable for 230 VAC?

Attached is a revision connecting the drives to the BOB terminals.

250V VAC Max

I've attached the LS harness diag, can you make sense out of it?

I could make some guesses but unless we're trying to reuse those wires I don't see much point in spending time on it.

I was hoping that the harness might have each axes' limit switches wired in series and able to be hooked up as is, but it doesn't seem to be an in series wiring method. I'll cannibalise the cable for other applications if suitable.

The link you sent me on Nov 30, https://www.mcielectronics.cl/website_MCI/static/documents/TB6600_data_sheet.pdf, states at the end of it's last page that resistors have to be fitted with 12 and 24 V supplies to the TB660, "to ensure control signal current is 8 mA to 15 mA" Does that apply to our use of the TB6600?

The BOB outputs to the TB6600 come from the 5 volt logic, no resistors required.

OK, how about the 24V into the TB6600 through connections 6 (VCC) and 5 (GND). That's all fine?

The 24 volts into pin 6 is correct. It used to power the motor and is also reduced to power the internal logic. The TB6600 has opto couplers to isolate its circuits from the inputs.

Does anyone sell it on Amazon?

Hello Ydsccfd, if you're talking about the TB6600, look at the links on ZASto's comment dated Nov 27. They are for a BOB ST V2 and stepper driver TB6600. You'll find some good attachments re those two components from him and MN300 over the last 6 or 7 pages.

I've attached the stepper wiring and colour code jpg, MN300. Would I be right to assume that the Red wire connects to the TB6600 terminal 4, Blue to 3, Green to 2 and Black to 1?

The Limit Switch harness is finished and tested with the multimeter - all good. The switches are connected in series as per your wiring diagram. Still to be attached to the BOB.
