Globing around nozzle and inconsistent first layer height
Once I try to do the first level calibration, the filament globs up around the hotend, does not stick to the heatbed, and the height is very inconsistent. Does anyone know why this could be happening?
You don't give enough information to help you.
What printer, what print sheet, what filament, and what temperatures.,
What is your history? New build from kit that has never worked?
What have you done to clean the build sheet?
Have you printed a calibration square (2" or so in size) and used that to set Live Z?
Post a picture of the result.
