Help with end gcode when printing wood filament

Posted: Sat Apr 10, 2021 1:38 pm
I am printing with wood filament at 165-185c and it is prone to clog/burn if left in the nozzle, so I want it to purge filament and then retract enough to exit the hot zone after it is done printing.

Does this look good? Not sure how far I need to retract, so if anyone else got any hint about how much I should retract then please let me know. I want enough for it to be in the top part of the heat break, but not so much that it unload.
