TMC5160 Drivers Not detected #1

Using the example Klipper configs, as well as RRF, my SPIDER KING won't detect the BIG-5160 drivers I have installed in my board.

Klipper reports:

INFO:root:TMC stepper_x failed to init: Unable to write tmc spi 'stepper_x' register GLOBALSCALER
INFO:root:TMC stepper_y failed to init: Unable to write tmc spi 'stepper_y' register GLOBALSCALER
INFO:root:TMC stepper_z failed to init: Unable to write tmc spi 'stepper_z' register GLOBALSCALER

And RRF reports all drivers not present.

Additionally, the example Klipper configuration pins don't match the Pinout diagram in this repo, so I have no idea which pins are the correct ones.

The example Klipper config I'm using is this (using the pin layout from the PDF file in this repo).

Big5160 boards are installed in the orientation from the WIKI - With the BIG-5160 text upside-down when looking at the board from the high voltage motor connectors.

Please help work out what's wrong here, because the board won't work without drivers :)

For anyone else finding this:

The BIG5160 drivers specifically need power on the 48V-PWR rail as well as whatever you have on PWE-IN. You can run 24v to both of these and the drivers will work fine, but you have to have both connected up, as PWE-IN does not provide power to the "High Voltage" motor drivers.

The configuration which worked great for me with standard currents (not tuned yet) is:

This is using BIG5160 drivers in the 1, 2 and 4 motor positions, X,Y and Z endstops in IO0, IO1 and IO2, the LED + RGB screen plugged into EXP1 and EXP2, and a normally-closed e-stop button on IO5.
