I just dry out my silica in the oven on a baking sheet with some parchment, works fine.

Synthbuttrange posted:Printing directly on the plate gives stuff a fat lip because of the extra first x layer exposure times. There's compensation built into slices these days but you have to manually enter the figure yourself. Printing straight on the plate is my personal favorite. Can cause problems with elephant's footing from burn in bloom but eh, worth it. Makes them a bit of a pain in the rear end to get off. Probably less so for you fancy people with flexiplates but I don't have one so I have to develop other tricks around that. As far as increasing supports, when I'm having issues like the ones above and I don't want to print straight on the plate I tend to try for one big, stonkin' huge support at the very lowest point of the model for mechanical stability by holding the weight throughout the rest of the print and then the rest of the supports are for overhangs, islands, bridges, flimsy parts and so on. I found that having one big rear end solid support at the bottom removes a lot of other points of failure along the print and allows the rest of the supports to do what they're specifically there to do, not be a distributed net of mechanical support for the entire print. Means having a bit of a sacrificial area but whatever, the underside of my prints is usually oriented to hide any other flaws anyway.

I do this too even on pre supported stuff, just toss a nice .5-1mm support on each foot for extra safety

For resin prints I've just been moving the actual model off the plate and having a raft + Heavy supports Everywhere in Chitubox after hollowing the object. No failures, just more patience removing supports later On an Elegoo Saturn S and using their settings with their resin.

Tiny Timbs posted:No it just got a lil melty in there You want to spread the silica out, if it's stacked on top of each other in a container the heat can't get in well. I had 5 kg silica pellets in a metal container that was basically just a cylinder, and 2 hours at 200F in the oven only dehydrated the top cm of pellets. But 45 min spread out on a cookie sheet did the trick.

My experience so far has been mixed, except for the very smallest of objects my PETG prints always have a large number of defects even if the basic structure prints successfully.

Some Bambu petg, but also Atomic, PrintedSolid Jesse, and IC3D petg. P1S here, so I always do flow calibration on any new spool. I also always dry all my filament before it ever goes in the printer (even new), which I think is pretty important. Using pretty much unedited slicer settings overall, but I'm printing structural/functional parts and generally completely solid or very high wall counts. I reduce volumetric speed to slow it down depending on how complex the part is. If I'm having a problem with a specific print, I'll do more tweaking but it's usually just speed related or dealing with support/overhang issues.

My prints looked like hot rear end until Orca came out with the calibration cycles. I swap to the smooth PEI sheet, clean it with soapy water, then calibrate the spool. Parts went from 'well, I'll take it, I guess' to 'it's like PLA, this is awesome' for maybe 15 minutes of time invested per roll.

What I really want is to be able to mix and match tools with different nozzle sizes in a single print (something I just sort of assumed was one of the things a toolchanger was for tbqh)

It'd be nice to just transition to not using PLA at all since PETG seems so much tougher while being the same price.

Has anyone ever seen a design for a lid mechanism like this? https://www.youtube.com/watch?v=qZb7JKCDM-8&t=6s It's an automatic pet feeder that opens/closes by folding up in the middle (rather than the kind that dispenses with an augur). Searching the sites like thinkgiverse/printables I haven't found anything like that, just the continual-dispenser kind. I'm also considering something that's just a section of a disc with an opening that rotates, although that would take up a lot more room to the side. I'm looking to make something that basically covers a plate or bowl (I can build a wooden box around it, or whatever) and opens and closes. Mainly because I need a couple, those store bought ones are $200 each, and the RFIDs don't always work that well. My cats have very different patterns so I'd probably take a stab at using a Jetson Nano I have laying around to recognize the cats via IR camera. And as long as I can drive it with a stepper driven by one of the super quiet driver ICs (same kind used in 3D printers I suppose) it should be quiet enough. I'm just running into, I have some ideas and I have a good printer but my competency at 3D modelling is terrible so I'm still pretty dependent on designs I can find.

I am dreaming of doing something similar, but just have a 'hey Google, feed the demons" and have it throw some food in a few bowls. The venn diagram of esp32 cards, public GitHub projects, and cad parts is too prevalent not to attempt something

At least in the pressure advance and extrusion calibrations I didn’t notice any difference between the two.

I have run the calibration for many different spools/brands and I still end up with basically the default settings. With the exception of my personal TPU settings, "bambu basic (pla/abs/petg)" has worked for everything I need to print Arguably I can make some adjustments in perimeter speed for some silk pla projects, but that is a wholly different setting

I just discovered that in Prusaslicer if you right click -> add shape -> gallery, one of the shapes is a universal hang hole. I thought that was pretty cool. Just add it as a negative shape and done for a hanging frame.

Man, some things are just so much easier and smoother in Bambu's slicer. Like color assignment to model regions, especially by height. It's simply WYSIWYG but in Prusaslicer it's so much less elegant. Not only is there no height "brush" with which to assign colors, but PS's preferred way to do that (by injecting color change pauses at certain heights) assumes a manual color change whose effect isn't visually reflected in the preview. Want to just use a different toolhead for the different-color filament instead of a bullshit manual color change? You can force a height modifier to use a different tool for perimeter/infill based on height range... but god it's such a clunky feeling way to go about it. I never thought I'd actually prefer Bambu's stuff, but they honestly really do have some nice features.

I bought a Creality K1 as a clearance/open-box item from Matterhackers. Matterhackers says their clearance items still pass quality checks. The printer had a frowny face drawn on the extruder housing, there was filament dried on the nozzle, and there's scrapes on the bed. Any other place I've bought clearance/open-box, there wasn't actual functional damage or issues - they might say an item is for parts or not working, or that there's specific problems. It was as-is, no-returns, so in the end it might just be "sorry, rube, you should have anticipated this" but I feel like there's a difference between "opened, used, returned, and verified that it wasn't in lovely condition" and "opened, used, returned, and immediately returned to stock for clearance sale". Caveat emptor for anyone else who's thinking of buying Matterhackers clearance printers, I suppose.

Yep, I opened a ticket as soon as I saw the issues and included a few photos. That was last Thursday. Called twice since then, both times it was "being investigated". Haven't had any actual response or updates. I'm opening a dispute with the credit card. I'll let them fight it out.
