I have an issue here with a hexagon print head. It keeps jamming a stripping the ABS filament.
I have tried different types of ABS and different nozzle sizes (0.2 and 0.35) and I keep having the same issue.
The one common thing I keep seeing is when I pull the filament to cut off the hogged out spot the filament always has a shell of filament stuck to the side of it.
It is almost like its backing up inside of the hot end. Also, with the print nozzle still hot and set to 245 you really have to yank hard to get the filament removed from the hot end.
I will also add, its not a clog because I can feed the filament back in and immediately go back to printing.
Anyone else seen this?
