0.10mm layer height using a 0.40mm nozzle, is it even possible? I only get jams (of the heat creep flavor).
The OrcaSlicer profiles shows 0.08 mm being the minimum and 0.32 mm being the maximum layer height with a 0.4 mm nozzle. I’ve printed multiple long prints with 0.12 mm layer height without issues so I don’t see any reason why 0.1 mm wouldn’t work.
What kind of temperatures to you see in the toolhead and chamber during printing if you suspect heat creep?
What material at what chamber temperature?
What layer height works with that combination?
I’ve tried PETT, PETG, ABS and PLA so far, in all cases the print begins ok, then it starts to look “gummy”, then it under-extrudes, then it jams/clogs, with the symptoms of a heat creep.
Chamber temperature of course depends on the filament used, and for my 0.10mm layer height attempts was what I would use for 0.2mm layer height as well. Same for bed temperature, of course. The only difference in temperature is that I tried to lower the extruder temperature after the first fails, as I suspected that the lowered flow required it, but I didn’t get a successful print anyway. Only with PETT it finished, but it looked worse than with 0.2mm though (that “gummy” extrusion that certainly didn’t help precision, and precision is the only reason why I’d like to print at lower layer height).
Also, I noticed that there’s only a 0.20mm layer height profile available for the Zero, there’s a 0.10mm layer height one but it’s for the 0.20mm nozzle only.
Other than changing the layers’ height (and first layer one, of course), I didn’t try much, Orcaslicer settings wise, as there wasn’t much to try, apparently at least. I experimented with both lower speed (to help extrusion and layer adhesion) but also the very opposite (to let the extruder flow more, once I realized the problem was probably heat creep).
I am waiting for (ordered more than a week ago, they haven’t even shipped it yet) the additional 2515 fan, maybe it will help with the heat creep.
I can’t speak to that specific model, but typically, layer height would be 25% to 75% of the nozzle height with .1 being at the bottom end of what is probably capable for that size. Have you adjusted your line width any? If I’m not mistaken, a .1 layer height would be closer to a .4 layer width.
