Recently experienced my first hotend blockage. I disassembled hotend cleaned heatbreak best I could changed the nozzle. Now it isn't extruding filament as it should. Any suggestions would help. I'm beginning to think it could be the filament I didn't have this problem until I switched from comgrow pla to strong hero glow in the dark pla and then rc3 colorchanging pla neither of the latter 2 mentioned have worked. The comgrow however performed great.
