I have no idea if its working I have added everything I think.

For each stepper, you need to run the command AUTOTUNE_TMC STEPPER=[stepper name here] in the console of mainsail, fluidd, or whatever you are using.

I am still not sure if the tuning is persistent or not. You can use the command DUMP_TMC (klipper docs here) to inspect the current configuration of your steppers.

What I still haven't figured out is whether or not the AUTOTUNE_TMC configuration is in any way persistent, or if I need to run the commands again after each startup.
