I noticed that if I double X_MICROSTEPS for my TMC2130 driver, the movement is halved. So moving axis to maximum makes it actually move to the center.

Do I need to double steps/mm when changing X/Y/Z_MICROSTEPS for TMC drivers? I can't find such information anywhere.

Thanks,
Tomasz

Yes. The steps/mm setting in the firmware is actually microsteps/mm, so if you increase the number of microsteps you need to change the steps/mm accordingly.
