Has anyone done a successful multi-material print combining Prusament PLA and Woodfill Linden?
I'm trying to do a 1mm layer of PLA followed by 6mm of Woodfill and keep running into "stuck filament" errors when the woodfill print starts. If I print the object in either straight PLA or Woodfill it works fine. I am using the standard Prusament PLA filament setting and a custom PLA filament setting with 195 degree layers for the Woodfill. The PLA head is using the standard 0.4mm brass nozzle while the Woodfill head is using an ObXidian 0.4 mm nozzle. Any thoughts/input is appreciated. Thanks!

It is not completely clear to what you are referring when you say "195 degree layers" but I am assuming you mean nozzle temperature. If so, this is very low for PLA, most PLA will certainly print (up to a point) at that temperature but you would have to be printing pretty slow in order for the filament to have time to melt prior to extrusion. Adding the compounding factor of a "wood" fill which is likely insulating the inner core from the hotend temperatures to some extent I suspect your issue is merely too low a nozzle temperature. Try increasing to something more like 210-220C (depending upon print speed desired) and see if that helps your problem.

I wouldn’t know about the woodfill filament but Prusament PLA prints correctly at 195C with a brass nozzle. In fact, I print it usually at 200-205C. In some instances, where there’re chances of curling overhangs, I go as low as 190C without issues (never exceeding a vol. flow of 15 mm3/s ).
At this temperature interlayer adhesion is less than optimal but still adequate. Apart from that, you shouldn’t have trouble with normal Prusament PLA, although Prusament PLA blend is another story.

Thanks for all the input. I swapped the woodfill nozzle from 0.4 to 0.6 and that solved my issue. I love the end results, but I swear if you look at a woodfill print funny it'll mess up.
