Ah I see. Thanks for elaborating. Unfortunately I don't have the experience
to fix this. My blinds do require changing from the defaults, so I think
I'll have to wait for now.

Thanks! If I understand correctly, the adapted config isn't quite working
yet for two steppers, or it's working but needs improvement? I'm looking to
use it for basic features: open, close, stop. What's the stuff that's not
working yet?
Yes indeed, the uart communication specifically is not working correctly
when using 2 or more steppers. You can probably make the bare minimum work
without the uart configuration, but keep in mind you cant configure the
current and microsteps of the tmc. Meaning defaults will be used, where
current is maxed out and the microsteps are all over the place (because of
how the pins are configured) x-Axis has 32 microsteps, y-axis 16, z-axis 8,
and E-axis 64. Have a look at the a4988-component
<https://esphome.io/components/stepper/index.html?highlight=stepper#a4988-component>.
Exchange the tmc2209 component with this one.

I have searched around on Aliexpress looking for alternatives and I think I found another ESP32 based 3d printer board which should work without messing around on TMC uart: Makerbase MKS TinyBee 3D. With this board you can set the microsteps and current via switches and potentiometer. The pinout diagram can be found here .
