And I need something that has the same overall form factor, or I'd just print out a desktop tray for everything. Everything else in the kit is either metal, reasonably durable hard plastic, or thick cloth, so I wonder why this part and this part only is so flimsy.

Probably because that part is only meant to hold things while it’s on the store shelf, with the expectation that the other bits get integrated into whatever storage solution you have at home. Tool box, tool chest, workbench, etc.

Anyone running a UPS backup for their printers? I was 2.5 hours into a 19 hour print* and had the power go out right before bed, I assume due to the storm going on outside. I set it back up and as I was laying in bed the power went out again; decided to call it for the night. Since I can only do prints this long on the weekend (and only on the ones where I'm going to be home the whole time) it's pretty annoying! I've heard of printers with a "resume" function, but don't see it anywhere on my Ender 3 Pro with Marlin. Not sure how useful it'd be; the 2.5 hour print had a big mark where the hot nozzle had stopped.

Power off resume is only vaguely functional. Even if the firmware side works perfectly, it's still going to end up with the print falling off the build plate (or being yanked off by the nozzle that's partially melted a little volcano in the print). Not that there aren't success stories, but it's always going to turn into a worse print that potentially wastes a bunch of filament as well as time. I use a UPS, it's a giant Eaton that I got cheap and replaced the battery. Just about any UPS is going to be helpful for a printer, though the bigger the better.

Not a proper UPS, but I do use a beefy surge protector that seems to have some limited buffering capacity in that regard, I dunno what exactly- I get occasional power flickers that would reboot my Mars Pro plugged directly into the wall, with this it weathers them just fine as long as it isn't out for more than a second or so. I know for resin printers you ought, in principle, to be able to recover a print if it drops out at a known layer transition that isn't mid-exposure, and if you don't move the build plate. You can definitely pause a program between exposures essentially indefinitely, it backs the head off and everything, and there's no reason you couldn't use a diagnostic program like UVtools to tweak your build file to start a print at a desired layer if it got shut off mid-pause. No idea if there's any way to retrieve the last printed layer after a crash, though. I've never had so much invested in a print that it was worth it to try a restart from a power-off crash, historically I've just eaten the loss and restarted the print from scratch.

I would think you would need a really beefy UPS for any kind of printing off of it. Quick googling suggests an average Ender 3 power draw is 125 watts.

Tool box, tool chest, workbench, etc. Normally I'd think so, except that plastic bit fits neatly into a hard plastic locking shell which, in turn, straps to the fabric...thing that holds all the other tools and also folds around itself to form a compact carrying case. It's clearly meant to be deployed like that.

Since I can only do prints this long on the weekend (and only on the ones where I'm going to be home the whole time) it's pretty annoying! I put my printers on some UPSes as I've been upgrading my computer ones. I've got the Ender 3 and Maker select each on some Cyberpower 685VA ones and the Sunlu S8 on a Cyberpower 1000VA one from like 2003. The 685VA were the smallest ones I could buy with Automatic Voltage Regulation back in the day where it'll use battery power if there's a voltage droop like a brownout. None of them are going to survive more than a few minutes with the power out since the printers are using ~150W or so (more when heating up initially I assume) but it helps with small power disruptions and gives me a slim chance to continue through an outage. When I had a bad battery on one of the 685s I tried using the 1000VA for the Sunlu and the Ender 3 at the same time but it would get overdrawn and shriek and turn off when the second printer started warming up its bed, so for now it's one per printer and I replaced the battery so they're all set up. I have a lot of power outages here in NJ because trees take out the lines north of me and I'm near the south of my power provider's grid, meaning large storms have a good chance of knocking out the power. We have a generator but it takes some time to get it hooked up and running and I typically wait a couple of minutes just in case it's a short outage. I could probably set it up in time to keep a print going if I really wanted my print not to fail but it would involve a lot of rushing around to get everything set up. I started buying UPSes after Hurricane Isabel in '03 killed my computer's power supply as well as the power supplies in a couple of the TVs in the house which were pretty expensive to have repaired.

Finally redid some wires, figured out an extruder was running backwards, and I am finally printing on the voron. Holy poo poo I will never use another printer again. Just throwing some loose pla on and it's just powering through a test cube. Minor issue with overheating I think but that was because I set the electronic cooling fans to 50% because I thought the airflow was good enough Time to throw the sides on and print some abs parts.

Thanks guys. There is a used/"like new" 1200w one for sale near me on Marketplace for $100 so I may see if the guy takes $80. Little brownouts (and sometimes longer ones, but can't do much about that) seem to happen a bit more living in a country town. Random question: does anyone else's pet seem weirdly attracted to their printer? My cat has a habit of coming up and sitting on the chair near it when it's in use. She can't actually see up onto the table to see what's going on, and with the enclosure/distance it wouldn't be providing any heat... maybe she finds the noise of the stepper motors soothing or something?

Took some modifications to the scad you sent me, but I got that bracket to fit for my pallet on my ender 3v2. Can't wait to try out the pallete tomorrow. Got a prusa mk3s+ on the way says estimated delivery is week of the 14th. This hobby started with a cheap 60 dollar printer from Amazon and has grown quickly.

gbut posted:Any recommendations for a food-grade filament (for toddler toys), preferably no sheen? prob not a good idea. PETG is what soda bottles are made from, so its generally recommended for food safe stuff, but : 1) Colorful stuff and different manufacturers dump a ton of extra chemicals in it to make it look nice , print easier, etc. Don't put it in your mouth. 2) You probably printed other stuff before that. Your bowden through hotend through nozzle as all the residue of all the previous prints on it. Think of it like the cheese slicer at the deli. Cheese , and only cheese is cut on it. Not even once. 3) the stacked layers on an FDM printer leave very small little recesses where bacteria can grow. Sanitation will be a bit of an issue. ABS is also an alternative, but all the above issues also apply. I have cookie cutters made from PETG but i cover it in saranwrap first. Stick with BPA free tested stuff.

SLA question: A friend of mine is moving out of the country, and is willing to just give me his Elegoo Mars + Mercury (which is a fantastic score imo). I'm a bit nervous about the fumes, though. I could set it up in a grow tent in our spare bedroom and try to duct out through the window. This would be a bit inconvenient, but doable. We also have a utility room with a bit of dryer duct that's been orphaned since we moved the laundry. It's still there, and still runs outside; I think it would be pretty easy to run some flexduct to that. Am I being overly paranoid?

gbut posted:Any recommendations for a food-grade filament (for toddler toys), preferably no sheen? The issue is the FDM, not the filament. The printing process does not create easily-cleanable surfaces. If you coat it with resin you’ll still wind up with little pockets and valleys for stuff to grow in.

If you really wanna make toys for a toddler, use the 3d printer just to make the tooling to produce the toy in an appropriate, child-safe/food-safe material, like printing a mold and casting silicone into it. As a rule, nothing you directly print will be foodsafe or ‘hygienic’, even if the material is fine the actual print is an incredibly porous structure that’s impossible to sanitize effectively. FDM, resin, it doesn’t matter. would assume any topcoat or sealant over the print will fail rather quickly given the wear and tear kids put on toys.

Damage your offspring by showing them that they can print their own printer upgrades. Then show them tinkercad. Wait. That is me that can't stop. So the voron has been running a rpi zero 2 for a couple days of solid printing and tests, all PLA. Today I decided to start tuning for abs and I also happened to add a new thermistor because I had it and more info is awesome. Now I keep getting klipper crashing/stopping with various errors. The pi temp never gets above 35c with a bed @100c above it. My USB webcam now starts to stutter and lag behind, eventually freezing. I just ended up removing it and the new thermostor I also had the pi almost run out of space with 3fb free normally. Full reboot and it's back, but I occasionally get a problem. Fingers crossed my overnight goes fine. But research shows it's a mcu timing issue, but I am positive I have it set fine. Top shows the links not cpi bound at all. I sometimes catch klipper or moonraker topped out on resources on the stst page, but Its only a brief moment. Logs aren't really showing anything. Where should I be looking?

Search the history for what I replaced, but it wasn't a huge amount. Mine was an earlier 2021 kit, a later 2021 kit was much improved. It's also make sure it's a 2.4R2 kit, as while the improvements aren't enough to make me go rebuild a good working 2.4, they're a definite improvement. I'd suggest if you had a few extra dollars, look at the LDO kit, if only because the extra included bits are really worth it. Klicky should have been official 2.4R2. Prove me wrong.
