So I finished building my first 3D printer, a Prusa i3 kit, I bought an E3D V6 1.75mm hotend for it right of the bat as I heard great things about it. I took my time to calibrate everything, I PID autotuned both the hotend and the heated bed, after a few test extrusions (in mid-air) that gave positive results I tried printing the usual test cube. Long story short after a bunch of failed attempts (bed adhesion problems I'm using ABS by the way) I didn't notice that the fan did not turn on automatically at the start of the print (not sure if it's normal, I will check if M106 is in the Gcode start or add it if it isn't). I since turned off everything thinking I clogged the nozzle, then once everything cooled off I opened the guidler and noticed that the filament was bunched up before the PTFE tube. I tried searching but couldn't find anything other than the causes, which I think I understand now (the fan should've been on and the filament melted before above where it was supposed to) but no solution on how to clean the tube, hopefully it wasn't right under my nose, if it was sorry about that. Basically I tried pulling the filament out from the top but it's stuck in there, I didn't want to pull too hard and risk breaking something, what would be the best way to go about this? Should I just disassemble the hotend from the extruder or can I take it out by perhaps heating up the hotend and pulling the filament? I used both Pronterface and Cura, hotend set at 230 and 240 then 260 after I thought I clogged the nozzle to see it if would start coming out again and it did albeit slowly. Thanks for the help, at least I managed to print a few spaghetti and a bit of a square, I will call this first attempt a success.
