@jay_s_uk ,
Mate, thanks for your reply, don't take too much notice of some of the other stuff you see here as I am still getting everything sorted!
Cable used for CAN is 1 twisted pair, shielded drag chain cable.
The yellow and white wires shown in the photos at the toolboard end are not connected, simply tucked into the heatshrink.
The polarity of the Can cable is good (CAN-H, CAN-L).
I have checked the resistance of the cable and although I can't remember the numbers off the top of my head, it was good.
The pad for the 120 ohm jumper has been soldered and tested ok.
The same eror message as M121 also comes up on the paneldue on power up.
The only other thing I have done is connect a ground on the toolboard with a 100K resistor to the metalwork of the hot end. There is no change when this is disconnected.
I'm wondering if I don't have the correct firmware on the mainboard?
