Filament sticking to nozzle
Hi guys, I have had some very nice prints out of mk2s now after about a week, however I am now having an issue. The filament seems to be attaching to the nozzle as it extrudes. I have attempted to apply glue to the bed, adjust the z first layer calibration and cleaned the nozzle tip. If I load the filament while it is already in it comes out cleanly, so the nozzle isnt blocked. Do you guys have any ideas why this could be happening?
This photo is a fairly bad example, but typically there is a large clump of filament around the nozzle.
Also, in some prints it goes smoothly for a while but then the entire print sticks to the nozzle, I am assuming this is one big issue?
Re: Filament sticking to nozzle
Looks like a simple case of poor bed adhesion.
You need some pure acetone (be careful because some contain things that can contaminate the bed) and some IPA.
Regularly clean with IPA and when that stops working use the acetone(on a cold bed). You will not need the acetone very often so a little will last a long time.
Never touch the bed with your hands as this kills adhesion for most materials.
If you have a set of vernier calipers you can measure the thickness of your first layer to ensure you are bang on 0.2mm.
Also have a search on the forum because the pinda is notoriously sensitive to temperature and will throw your first layer well off. There is lots of advice on how to deal with this.
