Hi, I was wondering if anyone can help me, I'm using an Ultimaker 2 with PLA however its seems that the filament is continually getting stuck and I cant work out why. I've printed things before with no problem but halfway through a print last night the nozzle appeared to clog and so no filament came out. I heated the nozzle up to 260 to unclog it, however the filament still wasn't coming through. After some research online I tried the atomic method which after several attempts appeared to work and filament was finally coming through, but then it blocked again. I retried the atomic method, and when I hand fed the filament it comes through, but once i reassembled to print again, very little filament came out and very slowly until nothing came through! Has anyone got any idea what could be causing this, any help will be much appreciated! Thanks
