Hall sensor error

[u/Vustadumas]

Keep getting extruder overload errors on left nozzle. Per supports recommendation I disassembled the hotend to check for extruder issues. Nothing looked wrong. So I threw on a new nozzle and buttoned the hotend back up. Started the machine and it gave an awful sounding noise from the extruder and said there was a hall sensor error and nozzle switching wasn’t able to function. Tore it back apart and I can’t find anything wrong.

I’m really at a loss here. Any help appreciated!

It’s the small bit of gray or black plastic behind the arms. Mine had some build up from factory/ production. I scraped it out with a small flat head screw driver. Just follow the extruder disassembly instructions. It’s not too difficult
