Clear all

CR10 Pro V2 under-extruding. Unable to clear the nozzle with the included tool, help!


Topic starter

My CR10 Pro V2 seems to be under-extruding PLA. The layers are really uneven. I tried to use the needle that was included with the printer to try and clear the nozzle (while it's heated to 210C) but it only goes halfway trough. If I wiggle or spin it around, it goes further and then I can feel resistance pulling it back down but there's no filament coming out and it never gets easy even after repeated attempts.

Is there anything else I can do short of picking the printer apart? This is really frustrating and I might just get rid of the printer altogether.

Hi friend. You probably got a clog issue. Check these two videos, please. You will find it is very easy to fix clean the nozzle.

Thanks Kevin, I really appreciate that. It has been a frustrating experience 🙂

I've not tried a cold pull yet but this is what I will try next. If that doesn't work then I'll buy a new nozzle.. unless that sounds like a bad idea, from your experience?

cold pull? Sorry I am not sure what is the cold pull meaning.
