Hi @Goatkeeper. I had a similar issue which started showing when working in a colder more moist environment. No movement on the z-axis. Pointing a heat gun (a hairdryer would probably also do the trick) shortly on the controller relieves the issue for me. I’m now using a new controller and while its also getting warmer here I haven’t encountered the issue anymore. Perhaps also check this thread: Z axis - No movement at all, Maslow 4.1 - #38 by Lasse
