I have the 0.35 nozzle and printing at 0.3 layer height works great. It’s when I print with 0.15 layer height using Lulzbot High quality slic3r profile I get prints that start out great and by about halfway through the filament stops extruding.
Also throughout the print there is a different sound on retraction, when I open the filament idler the Hobbed bolt has chewed into the filament.
I’d don’t believe there is a blockage as I’ve soaked the nozzle in acetone for a few hours (it was pretty clean anyway) and my 0.3 layer height prints always turn out fine.
I haven’t touched anything in the high quality slic3r profile, should I try reducing the extrusion speed? Would I be correct in thinking to print smaller layer heights the extruder would have to work faster with the filament?
