Wire length feedback - Optical encoder?
Created by: DegenerateGroundState
I watched the two build streams on the hangprinter on Thomas Sanladerer's channel and I remember hearing you have some repeatability issues when spooling/unspooling the wires, I'd go back and make sure but they're 10 hours put together! Have you considered using wires with a pattern on them combined with an optical encoder to close the loop on exactly how much you have on/off the spools?
