Connected all components, finalised Ports and Pins setup and looked at the following:

Voltages across Pul+ and Pul-, and Dir+ and Dir- are 4.7 V on average. So does the system senses that there is motion? An incorrect setting or something?

In Mach3 Diagnostics 'Time in int' under the 'Jog On/Off' button rolls from 5.2 to 7.8. I do not yet know what that means.

The Z limit switch inputs do not register; will have to examine the connections from switches to BOB.     
X and Y register as expected

X cable still in transit.

I'll do all that and follow your leads

The E Stop is wired under the board, between the board and the plastic container floor - pic attached

Still waiting on the stepper cables, everything else installed, wired up and tested. All voltages as per expectations, nil flame and nil smoke.

I set the microstep switches and tested B-B+ and A-A+ voltage as 23.8 V. I do not know how that translates once the  steppers are connected.

The computer has not been attached to the BOB as yet;
Question: should I at this stage, or wait till the steppers are attached.

I have set the Mach3 values as per the BOB User Manual.
Question: As I do not have spindle control, should I 'Disable Spindle Relays' under 'Config' - 'Ports and Pins' - 'Spindle Setup'?

Hi TPS thanks for providing the link.
KAISIR, Tweakie is right, this BOB will not run on Windows 10. My computer runs Vista, so will run the BOB. You might still have an antique XP or Vista disc in the back of the cupboard you could load, than you can save $25 by buying Mach3.

The BOB you bought looks like an exact clone of the ST-V2 I bought on advise of ZASto. He runs this in conjunction with 3 TB6600 stepper motor drivers. I'm installing this system myself at the moment. You can find great directions on the entire process on the post 'Looking for good DIY controller kit supplier', start page 7, Nov27. Good luck.

Mounted BOB and TB600s (that sounds sadistic) and wired them to each other. There was no bloodshed. 
Tomorrow I'll make mounting brackets for the 24V power source I received today and if poss also wire it to the BOB and TB6600s.
Must also make a housing for BOB, thought of a plastic food container just large enough to fit it. Screw the lid to the board, fasten the BOB on the lid and place the box over the top. I'll put some slits in the box for airflow.

There are E Stops between P10 and ground in the Limit Switch array, as well as between the Geecreit and the mains. Will I fit them both or will the 240V one suffice?

I'm still waiting on the motor cable - covid speed.

Hope you and all keep well.

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.

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

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?

250V VAC Max

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