recently i’m kinda finishing my printer and added the walls for the enclosure. But then my big problem started, the printer fails to consistently extrude filament, especially after a few layers. Also it will sometimes stop extruding at all.
What i tried to fix it:
- many cold pulls
- used different kinds of thermal compound, right now theres the original that comes with the E3D v6, but i also tried Arctic Ceramique 2 and Gelid GC Extreme. I only used them on the cold side.
- printed different materials, PLA, ABS, PETG
- removed the printer walls, but it doesnt make a big difference
- replaced the thermistor cartridge
- moved the cooling fan from below the extruder-motor to the opposite side, so it won’t push the heated air from below the motor
- used different heatbreaks, same problem with original E3D and Microswiss
- used different nozzles, no difference between plated copper, hardened steel and brass
- cleaned the filament pulley
- varied the idler tension
- higher/lower extruder motor current
Nothing really helped, one of the better prints i got was this one.
You can see how the inconsistency increased until it finally stopped extruding at all.
It’s kinda frustrating to deal with this, since i almost finished building the printer and i hope someone can help me figure out what’s wrong.
The electronics are seperate from the printer chamber and get active cooling. I use MKS Gen L Board with TMC2209 drivers and a 24V Meanwell power supply.
Have a nice day and happy printing!
