I switched to MatterHackers ABS when Lulzbot ran out awhile black. I have run through 4 rolls of it and it prints fine but I have had more clogs than in the past 4 months than in the past 2 years and I ended up having to change the nozzle 4 times (could not clear the clog out, tried acetone (for 3 days) tried burning it out with a torch and even tried drilling but snapped bits off in the nozzles.
They seem like a good company and I know people recommend them but is it possible their ABS has junk in it?
I print with .35mm nozzle @ 245c (I won’t go any lower as I need the layer strength). Eveything seems to be printing then it just runs dry and my extruder chews through the filament and the nozzle is a brick at that point.
