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. Exchange the tmc2209 component with this one.

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.

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. — Reply to this email directly, view it on GitHub <https://gist.github.com/lumascet/d5a12a8ba942864726f4c34d10feba12#gistcomment-4576584> or unsubscribe <https://github.com/notifications/unsubscribe-auth/AF5HUZOVACQBP3Y7P7KXWDTXHRSOHBFKMF2HI4TJMJ2XIZLTSKBKK5TBNR2WLJDHNFZXJJDOMFWWLK3UNBZGKYLEL52HS4DFQKSXMYLMOVS2I5DSOVS2I3TBNVS3W5DIOJSWCZC7OBQXE5DJMNUXAYLOORPWCY3UNF3GS5DZVRZXKYTKMVRXIX3UPFYGLK2HNFZXIQ3PNVWWK3TUUZ2G64DJMNZZDAVEOR4XAZNEM5UXG5FFOZQWY5LFVEYTEMJYHA2DENRVU52HE2LHM5SXFJTDOJSWC5DF> .

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.

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 .
