Skip this step if you do not have the TMC2208 driver upgrade.

To install the TMC2208 drivers you will need to make sure that there are no jumpers plugged in at the stepper driver locations on the control board.

You will however need to make sure that there is one jumper placed on the UART pins for each axis you have a TMC2208 installed.

Plug the TMC2208 driver into the positions shown, make sure that the trim-pot is pointing towards the power terminals, installing the driver the wrong way round will destroy it.

Note, the trim-pot doesn't need adjusting as these drivers allow us to control the current via the firmware.
