Help, Cutting problems

[Desertboy]

Things I have already done

Replaced the couplings they were crappy Flexible ones with semi crappy ones


Replaced one of my motors with a new 3nm one for the gantry as that was 2nd hand and underpowered, I also have 2 4nm cnc4you ones to drop on the bottom axis which has 2*1.8nm on it at the moment and I will swap one of the motors from my bottom axis onto the Z which has a 1.2nm 2nd hand motor.

Which won't help but at least it'll cut wrong a bit quicker.

Made sure the wiring is grounded from the spindle and the Nema's to the GX20 plugs and grounded the wiring from spindle to GX20 socket. The GX20 sockets are mounted on a metal plate that's grounded.

Checked the soldering and continuity from stepper driver to Nema motors.
