I have a very frustrating problem, my extruder clogs up pretty much immediately after cleaning it from the previous clog and I cannot figure out what the hell is going wrong.
I use a genuine E3D V6 in direct drive configuration (dual drive) and I print only PLA. I have tried many nozzle offsets from the bed but because I have to test so frequently I am just printing in the air for now.
This is what I tried:
- To print using the following temperatures: 200, 205, 210 and 220 °C
- Using different brands of PLA
- Lubricating filament
- Installing a filament dust cleaner
- Using both Bowden and direct configurations (my retraction setting for my direct drive setup is 0.8 mm, I am not sure what I used for the bowden but because the tube was fairly short it was probably around 3 mm. However I am not even printing I am simply running and stopping the extruder stepper, I am not using any retraction at all right now)
- Buying a brand new E3D V6
- Trying both 12 V and 24 V heat cartridges (with the respective power supplies of course)
- Checking the temperature with other sensors (yes the temperature is displayed correctly)
- Using acetone baths to clean all parts.
- Using stronger and weaker heat sink fans and fan options
- Push the filament manually
- Performing PID tunes
Even after all that the extruder clogs up usually mere seconds after it has been fully cleaned and inspected before being re-assembled. I make sure there is no bit of plastic or dust/dirt present before I re-assemble the extruder. I also hot tighten the nozzle but I also tried to run it without doing it but it made no difference.
I would love some help with this problem because I am pulling my hair out figuring out why this keeps happening.
