Yes, TPS, that would be good to look at because when all was 'running well' before it ran at a snail's pace.
The X, Y and Z resistances 5/1, 5/2, 5/3 and 5/4 range between 1.4 and 1.6 ohm.
The voltages between pins 6 (earth) and 1, 6/2, 6/3, 6/4 and 6/5, with the power connected and switched on but NOT with the computer attached, are all between 17.4 and 17.6 V. There are no connections between pin 6 and other pins that are below 17.4 V.

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

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

Found the reference to wiring 6 as a 5 wire

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?

Hope this gets there

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.

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.

Thanks MN300, but the colour code is not exact as there is no yellow but a brown wire. Looking at TPS' highlighted pic of the X Motor contact (Nov 19), 1=Blue, 2=Green, 3=Red, 4=Black, 5=White and 6=Brown=Earth.
Considering the above, which would be the centre taps or, how to determine them.
