Yeah I cleaned out the nozzle when I was in there as well, but I'd like some fresh one just because its good to have. I've only been using PLA as of now but I have a roll of PETG and ABS i plan to try and use at some point. The PETG very soon, but i'm gonna build an enclosure to help trap the heat in for when I'm ready to try ABS. Stepping stones. Petg should serve fine for most my applications (plastic car pieces that can survive without warping trapped in a car in the sun on a hot day), but I'd like to learn ABS in case I need it in any extreme cases. I'm using the Maker Select v2 right now, but if I get this dialed in and operating relatively smoothly I may grab a Prusa i3 Mk3 as an upgrade
