[Closed] Fliament blocking
After 3 years of no trouble like this .I'm having a problem with the filament blocking up where the coupling that joins the heat block to the heatsink is the smallest. Right before the heat block ,I have tried everything that has been recomened through chat's. Has anyone out there had this issue and how did you fix it ? Some times when I unblock and start over it will run fine foe 4 or 5 hr's and sometimes it blocks right away when I try to reload filament.
I heat up the extruder and push through manually, it's fine. I'm wondering if it's a buildup of material since it's running at 205 degrees (the manufacturers reccomendations).
