Upgraded my Voron 2.1 to 2.4, with more than a year of delay. Did some wiring overkill, because I wanted the goddamn wiring harness and the electronics decoupled.

Every 2-3 weeks I'll check out the Simplify3D forums for poo poo and giggles. The mods are still trying to keep up the appearance of a functioning company and ongoing development. Must still be pretty profitable to be doing that.

OpenSCAD is something for simple procedural things. If you need to start addressing specific edges or vertices, be it for simple fillets or defining feature aligned planes, you're in a world of hurt. That is, if it's even possible to address specific part features in OpenSCAD. (Is it? I don't know.) Do poo poo like this in OpenSCAD:

Pro-tip for Klipper users, that use a NTC100K beta 3950 thermistor. Apparently the beta calculation generates values, while mathematically correct, that are bad in the regions where you might run your hotend at. Over here I've apparently been printing at 260°C while 245°C was displayed.  This is a correct(er) thermistor definition: code:

It would be nice to have one for higher precision mechanical parts like RC gearboxes and diffs and poo poo like that. Assuming you can get resin with ABS, PC or Nylon like properties. Then again, if you could, I'd probably be printing a lot more things with SLA.

Get new linear bearings on AliExpress. LM8UU or whatever they're called. They're cheap as gently caress. Or if you're fancy, get those "drylin" bushings from Igus. --edit: Oh wait, this is a completely new Prusa. I guess they gave you a dud. The drylin stuff seems to be a recommended upgrade, anyway.

ImplicitAssembler posted:So, with a CoreXY, you could probably more than double your print speed. With that volume of prints, wouldn't that be worthwhile? A friend of mine got an Ender recently and was moaning about the slowness, despite running faster speeds in the slicer. He's been used to an old rear end Flashforge clone from China, running Sailfish (older version that only did GPX format), which doesn't know what acceleration is, they just shake like hell. I went to see, chuckle and note that the Ender runs at 500mm/s² from factory, which is pretty noticeable. What's that parameter that defines cornering speed? Junction deviation? I suppose upping that may help too, so that the accel/decel ramps will be a bit shorter, but also eventually introduces vibrations.

Nozzle X is a piece of crap. It's just tool steel with tungsten disulfide coating. Latter is supposed to be anti-stick, but got gunked up within three prints here. Just get a regular hardened steel nozzle, or one of the new fancy tungsten carbide ones (hard as gently caress, therefore relatively wear resistant, and way better thermal conductivity than the varying steel types).

That Prusa AFS the long-awaited Core XY of theirs? If so, that's sure a pretty penny more expensive than the rumored 1500 bux. Also, anyone here also in the Voron VOC channels, who was causing the drama? I'm on a hiatus and missed that one.

3D Printing Nerd just published a video recorded at Formnext, where some company has a huge 3D printer that does gel deposition with in-place UV curing. And due to that they appear to be able to print entirely supportless (within reason I guess, so long it's no impossible geometry kind of stuff). I'm wondering if there's a middle-ground possible for FDM, having an easy/quick to melt filament that is UV curable, so that you can force it to harden at temperature. I mean, it'll make it harder on the printer, since everything needs to be UV proof, but still.

I find that CHT nozzle interesting. While I don't really print at high-flow speeds (yet), I found what CNC Kitchen showed interesting, that the material starts building up internal stressed because of polymer chains something something, something which high-flow nozzles seem to reduce due to extended heating. Including that CHT, which is pretty compact, considering. I wonder if it helps with printing by reducing said stresses, that also seem to cause warping and additional shrinkage.

Even reading up on changing nozzles makes me nervous, lol. --edit: That said, ramping up speeds only does so much, if you're at low accelerations. I recently started to increase speeds, bumping perimeters by 33% and infill by 50% resulted in around 9-10% time savings, and I'm at 4500mm/s² (half of that on small features, a Klipper thing).

Wanderless posted:As soon as there's a Revo - compatible tungsten carbide nozzle I'll probably make the switch. (based on some of the reviews it sounds like that's in the works.) I use too many abrasive filaments on a regular basis to justify a system that doesn't have a high-wear nozzle but I imagine by the time they do exist there will be a solidly-refined bunch of Voron mounting setups from which to choose. Also, there's a beta version of the new Stealthburner print head for the larger Vorons out. It includes a mount for the Revo micro.

So I printed the accented front of the Stealthburner. It makes me wish I didn't go for bright pink as an accent color, and instead should have gone for the blue-grayish ABS I had. The pink works as gimmick when it's only visible partially, like on the 2.4 stock just a third of the printhead. I can't be assed to replace all the other accented parts, tho, because it also involves releasing the belts.

Or the filament has crud in it. I had some eSun ABS loving up nozzles left and right a long while ago and couldn't figure out why, until I took a closer look. There shouldn't be random black bits in yellow filament.

Step files would require slicer developers to adopt a geometric kernel for conversion into polys. And these are considered voodoo code. --edit: Oh wait, Wikipedia says it's also triangle based.

It's not enough to cause a problem most of the time, and it's trivially compensated for in software (we're talking 0.04mm in my case), but wow, this gold filament is just a pain to work with.

Commodore_64 posted:Even quality rails can be total bananas. They are meant to be clamped against a precision shoulder to make them straight and meet their performance specs. Obviously you are not going to do this on a normal 3d printer, just realize there might be some bow built into the things. --edit: Also, back when I've ordered my cheap rails from AliExpress, they just clustered them all together and rolled the bunch up on some cardboard and dispatched it like that. It's a surprise they didn't have any visible curvature.

Roundboy posted:See my other post, my nozzle was crashing the bed before the probe was trigering. So it might be worthwhile to check said coordinates. QGL however still needs manual offsets applied. For a while I didn't have them. While it generally worked, I always had a tilt in Y direction I never could explain where it came from (probe came too close to the edge), which got corrected away with bed mesh. Until I fixed that.
