@squeakycheetah Sure thing! I'm not usually around for real-time chat during the day, but I get messages eventually. n.n
@squeakycheetah It is! We should run up, rub them on our head, and stick 'em to the walls here. n.n
(For all I know, there's a fwoomp.social instance out there already, but I haven't heard about it...)
@squeakycheetah This bit is a brace for part of the underside of the printer itself: it adds some stiffness to the acrylic frame, which is bowing under the tension of the bed drive-belt.
It's fun, having a toy that can be used to upgrade itself! n.n

Print done, hours ago: left it to finish at 88% and got some sleep. Truthfully, there's not much you can do to save a print going wrong - just abort, reslice, and restart.
I'll take some closeups of the areas that didn't print well tonight: they all have a common element that I can compensate for on the next print. Fortunately, they're mostly cosmetic: I can use the print as it is. https://awoo.space/media/QlqUZbHulJwnVa2wz0k

Overhangs and undercuts are the bane of casting and 3D prints alike: you can't print on a surface that isn't there. There are tricks, however. Bridges can span short distances. You can model or autogenerate supports that break away when your print is done. Or, if you choose the angles and slopes of your curves really well, and get the temperature just right, sometimes you get lucky.
72% done, 18mm down on the bed.

Top skin is on 90% of the print: now the support flange is going in, atop the T-shaped gap where the infill is still visible. 8.8mm down: should speed up as it finishes off the thinner remaining structures. (Hence the previous "50% done. Ish." comment. Time estimates on prints is an arcane art...) https://awoo.space/media/fY8o3CElJX12viiv9tI

Top layers going down - first few are scribbled across the cubes of the infill, then longer strands are supported atop those. The last, topmost layer should be smooth and flat. (Fingers crossed...)
7.5mm down, print is just over half done. Ish. https://awoo.space/media/ngv0ugTVXsIoxMHaGaA

When you set up your 'slicer' - the software that turns a model into a set of printer instructions - you can specify the rate of travel for the extruder at various tasks. For perimeters - the 'sides' of a print - you usually want to print the outermost wall slower than the inner walls, which gives it a smoother texture.
Apparently, though, you *can* get that backwards and it'll still work for big enough pieces. >.<
@literorrery Eh, hugs are better for me than cake anyhow. **hugs**

InfilI happens once the bottom layer is down, between the inner and outer perimeters that make up the outer skin of the print. You can have any degree of fill from 0% hollow to 100% solid: 15-20% is usually enough to support a structure without much weight - or cost. Filament is cheap, but solid structures suck it up *fast*.
This is a standard rectilinear fill. I'm also quite partial to hexagons. n.n
2.5mm down on the bed now.
@ElectricKeet Sounds refreshing!

Keeping the plastic adhering to the bed and itself is a balancing act. I favour PETG filament: recyclable, no fumes. This particular batch enters 'glass' phase around 230-240C, so I print at 235 and start the bed at 70, dropping to 50 once a few layers are down - I want to keep the print cooling evenly, not melt it into a blobby mess.
About the first mm of plastic is down here on a piece that takes up most of my bed's footprint.

For a fused filament 3D printer, plastic needs to stay where you deposit it. Working with layers that are 0.08-0.24mm thick, the adhesion of the first layer to the bed is essential. My print bed is leveled at the corners: a microswitch tells the printer where Z=0 is, then I adjust all four mounting screws until the entire bed is in the same X-Y plane as the extruder travels, and is about a sheet of paper's thickness away from it. https://awoo.space/media/hr0OR4VcUZVt5_7Eyu8
@squeakycheetah Yep! Still feeling the place out myself, but it seems welcoming and earnest. Glad to see you here!
@mawr oh my ghod it's Literal Phoenix T'rill. XD #helpingest

@mawr For the longest while, the only medical research that seemed even remotely permitted on weed was the anti-nausea aspect; seemed to help patients undergoing chemotherapy. Glad you found some relief, mawr!
@Aradia@mastodon.social @ElectricKeet I remember Weebles. They wobbled, but they just wouldn't stay down. I BEGGED them, "Just stay down! If you stay down, they'll stop!" But no. Too proud. Too stupid. Too damn Weeblish. Not the brick. Not the potted plants. But then came the bed of Silly Putty... and the sledgehammer. And they stayed down. Oh ghod they stayed down.
@literorrery Digital Den Mother? n.n Congratulations!
@ElectricKeet @literorrery It is shiny, yes. XD
