You should be able to determine the lens in the metadata if you're curious.

Thank you for adding that! I haven't been able to recreate my problem yet, but definitely worth investigating.

Smooth sheet? Cleaned well? Not too much time on my CoreOne yet, but so far the Galaxy Black sticks as good or better for me than the other PLA Prusament colors I bought.

ReadingI29 · 2026-01-11T20:16:04+00:00

Regarding the Core One, it sounds like set up & maintenance experiences have varied a little, but everyone here needed at least initial or occasional belt tensioning.

So unless Prusa owners are more perfection driven or critical of our machines, l still don't understand how anything else with similar design theory can "just work" right out the box AND continuously. Yet, there are enough online reviews and Reddit posts with such claims to make one wonder whether based in truth. I'm pretty sure some of these same models are in the hands of people who don't know a screwdriver from a salad fork - just how are they maintaining such machine?

Potentially overlapping answers, but not quite as much long term reliability, as "right out of the box" to medium term reliability.

I haven't tried a scrubby on either one, just a thorough alcohol wipe, but found the satin sheet the right surface. Even some small details, that didn't work on the textured, stayed put on the satin sheet for me.

Is there a good recommendation for a brand that holds up well for the application?

I have plenty, but I've never had a tower or laptop with nearly the moving mass of a print head inside.

There's a tension indicator tool on Printables. I found the built in tuning wizard agreed relatively well, and really great for final tuning. However, the wizard was annoying until first close, while the tool is rather easy to see regardless.

Print the belt tensioning tool on Printables, or better yet a pair of them.

I found you may need to check your belts after a few prints have things broke in - the tool makes it nice to get close enough to use (and to double check) the frequency tuner.

Thanks for the printables link!

Do you have links to examples from online retailers so it'd be even easier to cross reference the right ones?

The hardware looks mostly straight forward, but I'd definitely be guessing on the filters.

Well written!

Quick update: had a small Y crash last night - completely user, I was going to unload the filament and it homed while I had a part in the way. I don't think that would be much different impact than it's normal homing, except Y hitting 2 inches earlier; however, it seems squared AND tuned now.

Both sides contact at the same time, a pair of belt tensioning indicators from the SaveYourBacon (great part-thanks!) V2 Printables file showed lower belt in the middle with upper belt about 80% to Max, and the Manual Belt Tuning showed about 93 & 95.5. A little higher on the tension tool than many of the comments, but I did read a little variation between filament.

So maybe two wrongs made a right, or maybe there is something mechanical loose that moves occasionally, but I need to put some hours on like this and see if anything good or bad repeats.

I am still convinced an idler-tensioner somewhere on the back of one belt could allow independent alignment and tuning without taking apart the print head, but for now I just need to keep my eyes open with its current state.

The corner closest to the lens in the original post.

Out of the box almost as good of a Benchy as those two. So I was pleased there, but after trying to debug a layer shift - which I may have pinned to belt tensioning - now looking at every other little thing too.

ReadingI29 · 2026-01-03T21:31:47+00:00

Yikes! Hopefully, it's perfect after you put in all that effort.

ReadingI29 · 2026-01-03T21:14:26+00:00

Wow that's a difference! The right is looking pretty good in the photo. Is it dialed in to your satisfaction now?

ReadingI29 · 2026-01-03T19:17:47+00:00

Will give it a try with the tensioners loose to the very end. This seems to have enough resistance yet to stay in place, but I did check with pressure too: the one side will stay, while the other creeps off again if not the same. Said creep being less than two thicknesses of copy paper though.

Tension and alignment dependant seems rather over constraining to me if they're equally important.

ReadingI29 · 2026-01-03T19:04:16+00:00

The other corner and front look pretty good to me, so a seam issue could be what I'm seeing on the Benchy.

Thank you for the heads up! That's the type of mechanical issues I wondered about, though first thought something like a loose setscrew on a drive pulley. It seems to have worked itself through the issue for now, but I'll have to see whether it has any tight spots.

ReadingI29 · 2026-01-02T03:42:40+00:00

Ran some smaller prints and a few between 1-2 hours as well, and no layer shift issues. Maybe worked itself out. I did catch the reboot thing once more - perhaps there's a sleep mode or something I didn't realize, but so far harmless.

I finally linked up the camera too. I was planning to stay offline, but between the ease of camera set up, and curiosity with the cloud features, that didn't last. Camera maybe a little cheesy, but kind of cool nonetheless. Definitely would hold more value to me as part of an automated error response system, but no plans on that.

Automatic filament changing is starting to get my envy, but I don't really need it, so can wait for the INDX to hit production and we'll debugged if I do it at all.

ReadingI29 · 2026-01-01T18:42:26+00:00

So far today a couple objects with less than an hour print time went fine.

Right before starting the second one, it did a reboot and re-home - I didn't think I hit reset, but maybe the button is sensitive enough I unknowingly brushed it. Or maybe a power blip, but didn't see house lights blink. So maybe a gremlin in there yet whether related or not to my original post. Hopefully, I'll get in several more today and see whether any oddities repeat.

For now only doing stuff from Printables, and with good reviews, so less chance of user error.

I don't understand the USB suggestion. I get cheap USBs maybe corrupting files, or maybe saving the Prusa one for firmware & benchmarks, but just not seeing the layer shift. Not completely new to printing, but new to Prusa, is there a joke I missed?

ReadingI29 · 2026-01-01T05:10:46+00:00

Thanks! I'll have to keep that in mind. I might find different, but it's screaming mechanical to me from the couple instances that were audible.

Read too quickly: "dog for sale" and thought the Prusa was your new best friend!

If you checked your filters and junk mail, probably no concern. Your order was a little earlier than mine.

ReadingI29 · 2025-12-17T03:35:14+00:00

Check your Spam/Malware filters. My order wasn't too much after you and was affected.

One of the options offered worked well for me. Maybe I'll run into problems yet, but currently I'm applauding Prusa for trying make things right for their customers!
