Anyone here experienced an issue where it will print fine to start and then within a few layers it clogs and quits extruding. I thought maybe I had a clog or whatever but I replaced the Bowden tube, nozzle and cleaned the hot end and still doing the same thing. Not sure what I’m missing. Anyone have any other ideas?
Check your heat break - If the teflon inside it is starting to wear out/flake off it could be causing the problems that you’re seeing.
I agree with Myke on this one but one additional thing to check is your retraction, If you are using Bowden usually 4mm is plenty, if you are on direct drive 2mm is a good point to start.
Have you changed anything in the printer lately?
