Irregular extrusion

Do you have the latest version of the firmware installed (1.13.1 - July 21, 2021)? If not, that should address your adhesion/leveling issues, as there is a mess leveling bug in all firmware prior to 1.12.2.

Be aware that the firmware also has WiFi fixes that may require you to perform a full factory reset (Controller and Touchpad), if you run into WiFi issues. The factory reset will fix those issues, but just letting you know that it might happen.
