I'm using a TMC2208 - Nema 17 combo to raise and lower blinds. I'm powering the system with a 24v PSU, and while the blinds are quite wide, the setup is able to raise them 90% of the time.
I was wondering if increasing the PSU voltage to 36v (max for the TMC2208) would yield more torque? I've decrease the step speed dramatically and it has helped a lot, but I want them to work reliable 99% of the time.
If the blinds fail to roll up even once, that will cause a calibration/indexing issue that will be unfixable until re-calibrated.
Switching to a larger NEMA-17 isn't an option because the space between the wall and the window is only a few inches, so a larger-bodied motor will not fit.
