PS: Note that for the Onefinity Machinist, Woodworker X-35 & X-50 and Journeyman models with the classic “Z-16” Z assembly, in the Motor 3 Limits settings, ‘min-soft-limit’ has to be set to “-133” and ‘max-soft-limit’ has to be set to “0”. If you changed settings and are not sure what are the correct defaults, you can reset to defaults for your model on the ADMIN page. I assume you have firmware 1.0.9.
