So I’ve had my 3D printer for about 3 months now with nearly no issues, it’s a CR-10. Recently I replaced the filament with a new roll and ever since then I can’t get anything to print. Every time i try to print, only a small amount of filament extrudes, and with 3 minutes of every print the extruded is above the print and nothing is extruding. I completely unclogged the printer last night, I replaced the nozzle, and made sure the tubing was completely clear. There was a bad clog but I removed it. After setting everything back up, I’m still having the exact same problems and I’m running out Ideas. Or other thing I noticed is that when I go to print something, after I’ve leveled my bed, the extruder will raise up about a mm past where I had leveled the bed, which is a problem I had never encountered before. Even when the bed does level properly, the filament still doesn’t extrude properly and it’s starting to feel hopeless. Any tips or advice would be appreciated.
