Ender 3 V2 has flow rate and filament grinding issues



  • Creality Forum,

    My Ender 3 V2 was working fine until recently. I have already calibrated its e-step and everything. But it has been having adhesion issues with MatterHackers PETG. I thought this was due to a clogged nozzle, but I ran eSun cleaning filament through it and the problem remains unresolved. The only way to get it to adhere and not under-extrude is to crank up the flow rate to 150 in the Creality Slicer. But, when I do this, I run into a different problem: About 10-20% into whatever print I'm doing, the printer starts grinding into the filament. I ALWAYS level the bed before doing any prints, but it still keeps doing this. I tried adjusting the z-offset to counteract this, but it only delays the problem for a few layers before it starts grinding the filament again. What should I do? Has anyone else ever had a problem like this before?

    Safety and Peace,
    Hoof and Horn
