Hi, first of all THANKS for your work!
When i see your project i started to buy all and printed 3d parts (and ordered pcb’s).
I finished to mount all and test, i see all go good endstops work and motion work.
Only i have one problem and i think its steeper driver problem i bought tmc 2100 This one in aliexpress .
When i home all axes i see only rotate a half of total circumference and doesn’t reach the end stop, i see this problem are in two arms, the same issue.
I don’t remember correctly, but this problem it’s related to microsteping config? (maybe my driver have different config without jumpers in cfg’s pins).
Maybe I’m wrong i appreciate some help for understand the problem.
Thanks for your work and help 🙂
Edit: My scara it’s the same as your model with 488 and 158 gt2 belts i doesn’t changed nothing.
