Help!
All of my prints were coming out perfect. Now randomly, my top layers have gaps in the walls and some aren’t even printing at all. I’ve tried so many different fixes, I even replaced my entire hot end. Does anyone have any guidance on what could possibly be the issue?
Start with these, let me know if this works:
If this is an Ender go to the LCD panel: Control → filament → if E in MM3 is on then turn it off.
Check your extruder - do you have the plastic handle? Sometimes it gets a crack in it.
