Going the other way, you'd want to run until empty, pull the nozzle, then pull out remaining polymer with needle nose pliers.

I found though at 150C my motor really started to struggle, so now keep the temp around 155C-160C. Fine-tuning the distance of the fan to nozzle also made a difference - as did the angle at which I guided the PLA out of the nozzle onto the winder. It seems to be more of an art than a science for me atm...

On a slightly different note, how would I go about purging a previous batch of PLA from nozzle and barrel in order to clean everything properly?

remember pla takes a lot more cooling, so add fans. especially on your vertical setup.

If you happen to have Harbor Freight in your area, they also have a small metric drill bit set that has served me well so far.

You will need to get a metric bit, McMaster sells them. I'd recommend 1.7mm.

I also have just used a 3mm nozzle and went hot with the pla and let it pull down to 1.7 and that worked actually pretty good, but not as consistent.

If I Lower the temperature PLA does not seem to extrude anywhere near as fast (Inches/Hour). Is there any way to increase the filament width without drilling the nozzle? Any Suggestions?
