The stock printerheads (Mini 1.03/1.04) are pretty forgiving, but I’ve been having trouble getting a good tension on the filament feed for the Micro head - grinding off filament, where the filament can’t feed anymore.
I’ve experimented with tight, loose, and everything between. Once I start seeing the filament bits in the metal herringbone gear, I abort and try again. (I managed to get halfway through a print, once, before it started grinding off.) I use the nut to gauge how tight the feeder is. (Looking at it from above, the nut moves away from the filament when you turn the dial clockwise, loosening tension.)
- If it’s a question of tension, where is your nut in the loose/tight spectrum?
- If it’s not a question of tension, what should I be experimenting with?
Thanks for any feedback, and I hope others get use out of the discussion.
