Filament jam

[joestefano]

My filament is jamming while printing the attached model. I have printed it twice and it jams at the same place. I'm thinking that the distance of travel between the square posts is allowing the filament to cool and jam. After canceling the print the jam is easily cleared by retracting and extruding a couple of times. What setting can I adjust to help with this issue? assuming my theory is correct. I am using a direct drive extruder setup. PLA at 230C.

Check and lower the retraction distance. Which printer is this ? What hot end does it use ? PLA at 230 is pretty high. possible heat creep

If you are at 230 for PLA and moving a long distance without any extrusion I think heat creep is suspect. Also retraction settings to long and to fast can add to it.

This is a CubeX printer converted to Duet electronics. I am using E3D hot ends. I normally print this PLA at 210-220 I raised it to see if it would help. Can you take a look at my FFL and suggest retraction changes. How do I combat "heat creep"?

As long as the e3d is assembled correctly, it will not cause any issues. Is it the genuine or a cheap clone ? Is the hotend fan running continuously ? Is the direction of the fan (physical) set correctly ?

Sure, post your FFF.

I may or not have done a stupid thing. I installed my heat break into my heat sink with thermal epoxy (original E3D hot end) I now have a heat creep problem on 1 out of 5 hot ends. Thoughts????
