Does anyone else have an issue where the printer doesn't home the z axis properly? It seems hit or miss where it will try and bed level and wipe the nozzle ~10mm in the air and ultimately fail. It seems to work if I auto home the printer before starting the print.
I imagine there's a problem with the start g-code but don't know what to change. This is the starting g-code it should be the default printer profile.
