Thanks, so that means that the resistance between wires 5 and 1, 5/2, 5/3 and 5/4 would be the same, while the resistances between other combinations (i.e. 1/2, 2/4 etc) would differ.
I did read somewhere in Lin Engineering that the hybrid 6 wire 5718L series motors (my motors) can be connected as either a unipolar 6 wire or bipolar 5 wire but cannot find the references anymore. Will go looking.
I'll check the wire harness to see if wire config has been changed between the motors and the board.

I am waiting to hear what the winding resistance is. Also a few voltage checks would be of interest. With the drives enabled would you please measure the voltage from ground to pins 1,2,3 and 4?. If you have a basic stepper drive two pins will be the nominal supply voltage, about 17.5V and the other two will measure about a volt.

Hi MN300
My friend with the multimeter, but most importantly, 'know how', will be here most likely Monday, possibly tomorrow. We live remotely here so have to travel some distance to meet. I'll have all the data then. Will definitely also look at the voltages as suggested by you. Also the harness configuration.

Hope this gets there

Yup, it did.
I checked the harness. The brown wire is a separate circuit board to motor casing/CNC frame earth and does not come out of the motor. The motor is a standard Lin Engineering colour code 1 with a yellow wire (pls view last attachment). The white and yellow wires are combined and insert into TPS' 5th pin into the board.
I have not as yet found the reference to wiring the 6 wire 5718L motor to 5 wires; still looking.
So does that mean that pin 5 yellow and white are the centre taps?
Also, does the motor now function as a bipolar?

Found the reference to wiring 6 as a 5 wire

just for swapping the axis that is all.

to have a "deeper" look into your configuration pls post your Profile XML file.
anything is possible, just try to do it.
if you find some mistakes, in my bad bavarian english,they are yours.

My attempts at attachments keep on showing errors, I'll try again

Worked this time. I have to thank you (TPS) and MN300 for your time and effort, it's invaluable. I'm on a steep learning curve and couldn't do it without you.
You have my kindest regards
