Losing steps/position, again

Stepper: If it goes in the wrong direction, swap one pair.

Pull the EN signal for now - without the enable signal the driver defaults to ON. Once you get it working then re-assess if this is part of your e-stop strategy.

DIP-switch, start with 8 micro-steps and maybe 2.5A or thereabouts. If the motor gets uncomfortable warm then think to reduce - but that current should be safe.

I am just getting a knocking noise - no movement.

I forgot about the 5th and 6th wires from the steppers. They run from the stepper to the underside of the cabinet - I will try and trace th- this may take some time.....

UPDATE
I have manage to get underneath (glad the router wasn't sat on a table) and it looks like the rogue blue and white cables are connected through the umbilical (the wiring diagram I have does not show them). Thre are several identical multicore cables going from inside the cabinet through to the underside and as my arms aren't long enough I am going to have to leave it until tomorrow as I don't want to cut the wrong ones.
