Voron V1 - SKR 1.4 Wiring

Initial Preparation

If you’re using the TMC2209 stepper drivers, use a small pair of wire cutters and remove the (diagnostic) pin marked in purple. This is to disable sensorless homing, which is not needed for the V2.

Then reconfigure the on-board jumpers as shown.

SKR 1.4 preparation
