I have a QidiTech Dual Extruder 3d printer. I’m struggling to get the filament to adhere to the bed, as a result when I start a print the filament just builds up around the extruder and not on the bed.
I’ve tried to level the bed many times and watched numerous YouTube videos, I must be doing something wrong, I’m using the levelling card that came with the printer, I even bought a feeler gauge, but still no joy.
There is a grey area, in that no one on the videos describes what the contact between the extruder and the card should be like, should there be friction, if yes how much…should it move freely?
