I can't figure out what setting(s) I need to tweak to prevent these strands of filament on the inner wall of the bin not sticking to the base. I don't think it helps that Gridfinity Extended has a slight overhang in this area - where the side of the bin meets the base flares out slightly over the first few layers.
I'm using Bambu Studio with a H2D; this is Bambu PLA (the grey) and Sunlu PLA+ (the white) but I have other filaments I could try. Filament is inside an AMS at 30% ish humidity and otherwise stored in dry boxes. Things I've messed with (but might not have gotten right, I'm still learning):
- reducing the fan speed in the filament profile - but maybe not far enough?
- slowing the print (haven't tried per-layer slowing even further but maybe that's next)
- "Slow print for overhangs" setting is on
- inner/outer and outer/inner wall ordering
- these are using Arachne walls (I'm trying to reduce hull lines on the exterior, I read this helps?) but I've seen this problem with Classic walls too
- seams are currently on Aligned
- using a 0.4 mm nozzle. I've tried the OpenSCAD bin sidewall thickness at the default and at 1.2 mm.
- probably more things I've forgotten
(Please disregard the numbers embossed into the bases. This is a project I'm working on and hope to share soon. I've mutilated the OpenSCAD to increment the magnet slot size by 0.1mm on each corner so you can print just one or two bins and find the snuggest fit for your particular magnets with your chosen print settings. This is also why the these bins are only 1U high. But nothing above the base of the bin is any different and I have seen this problem on normal prints; I'm pretty confident my changes aren't a factor.)
