I'm having trouble with the TMC2209 firmware.
If I upload the script to my Arduino Uno, I get Timeout Exception: No response from controller.
It works fine with Easydriver script and also tested it with A4988 script.
Both of these work fine and I can get the stepper moving as well.
I tried the DRV8825 script with the TMC2209 driver, I can connect to it, but can't controll the stepper.

Any Ideas?

Regards.

Hi Jan,

Maybe a problem of Baud Rate, the TMC 2209 firmware works at 57600 Bds.
