I have the Creality CR10 S5 and i am using ABS that i make (i dry the pellets and everything first and have a good spooling system there may be a bit of a diameter variation but nothing too bad). This print had great bed adhesion Bed: ~100 Nozzle: 270 we have built in enclosures for our printers and heat bulb above the bed that gets the ambient air around 46C inside the enclosure. I noticed that at the start there was under extrusion and i found the cause to be the drive gears not being able to pull the filament as easily through the enclosure as it should so after fixing that the bottom of the print was almost perfect but then up the neck it looks like under extrusion again. Any ideas?
