Hello everyone. I recently finished my mini kossel build and i am struggling with extruder/hotend now. I use airtrippers v3 extruder with MK7 gear from repraworld.com. The problem i am facing is filament slipping/grinding, when it reaches the hotend. It seems, that filament is stuck somehwere in the hotend and it creates a jam, causing filament slipping. Any ideas, how to solve this issue? I am using 0.25mm nozzle.
When i set 230 degrees, it turns a little, however, filament is still slipping, bearing rotates with pauses video of issue happening: https://onedrive.live.com/redir?resid=C ... ideo%2cmp4
I saw in the questionnaire you aren't using a fan duct. Why? You need one. Also that extrusion looks really fast. How fast are you commanding?
Sorry, I missread the question. I am using fan duct included in the kit. My extrusion feedrate is set to 50 on Marlin sofware. What is Maximum feedrate on 1.75mm bowden? with a 0.25 mm nozzle?
