I’m starting to get prints that have some layers that are being under extruded so it looks like it’s a hot end tear down and cleaning in my future…
This is the stock ender hot end and I was just wondering if there are any mandrel type tools available to help clean out any filament from the bowden tube path before re-assembly?
Quite some time ago I followed the Luke Hatfield hot end mod with the short peace of tubing and washer and it has working great until I have a jam due to a “knot” in my filament that somehow made it all the way to the hot end.
Long story shout, I striped the hot end, cut out the “knot” (picture to follow) re-assembled and finished the print. ever since then I’ve been having weird issues with my prints, mostly under extrusion at random layers.
