Any #3dPrinting #Makers have any experience of clay/stone filament? Have had failures using formfutura stonefil as its building up on my extruder gears and ends up just wearing out the filament and not feeding. Other than slowing the print speed, should I loosen the idler springs too? Any other tips? (have a 12hr print to try and make work, failed halfway yesterday)

@bracken hace you ever tried clay infused pla? Or any advice for filament clogging up the extruder gear?

@sldrant I had no idea one can print clay/stone. I presume they need firing afterwards though?

@gregalotl no it's 50% clay/stone in pla filament. Just having some issues on longer prints. https://formfutura.com/product/stonefil/
(there are also ones you can fire, but they're totally different)

@sldrant I've used bronzefill without issue. I assume you mean the teeth which grip the filament, not the gears driving them.
What size nozzle are you using? With modern toolchains there's no real need to go smaller than 0.6mm. so there could be an alternative to slower feed rates there.
Also try cleaning the nozzle. Feed some PLA through at 200C, cool to 80C, then do a big retract. Repeat this until the end of the filament you retract resembles the shape of the inside of the nozzle.

@bracken yes the teeth on the planetary gearbox collect the clay filament until it loses grip.
Hoping lower speed helps, but will try a cold pull clean too as it's not a new nozzle. Maybe should buy a 0.6 nozzle to try on the mk4 too
