I’m having a bit of trouble with my Ender 3 Pro; It has been struggling to extrude as it was in the middle of 3D printing. I’ve tried unclogging both 0.8 mm nozzle and hot end altogether, tried applying pressure on the filament, and still nothing. But it is important to keep in mind there was a 3 mm layer of PLA on the TOP of the heat block and I had to chisel it off (it cracked away with ease), and it didn’t appear to be physically damaged, so I screwed it back in place afterwards and tried to 3D-print again, only to no effect. And I don’t know if this could contribute to the cause, but I also stored the filament in no enclosed container and the first time the extrusion issue occurred, my Micro SD card got corrupted, which I thought was the cause of it, but I got a new Micro SD card and I checked the extruder, and no gripping issues to be found even while I was applying the pressure on the filament during the attempts to 3D print, but the filament wasn’t going down. Does anyone know what could be the cause of the issue? Like I said before, I am a new guy to the community and have my own thoughts why my printer stopped working, but I guess you can say I’m trying to compare notes. if anyone can help me out it would be a big help. Thank You. -SC
