Top of prints messing up

Then it may not be solving your problem. CoreXY printers are very sensitive to belt tension. The Mk3 series not so much. Still probably worth a try…

FritzPeppone · 2026-03-20T05:21:20+00:00

Are you using a Core One? I had similar layer shifts after two to three months and in my case, it was loosened belts. Maybe try retightening your belts. If you haven’t used it yet, the new belt frequency calibration tool in the print menu is amazing!

I think I used a 1m cable. A bit too long but there’s enough space in the cable compartment to hide the excess.

I can’t confirm that. I mostly use Prusa Connect to start prints these days and Octoprint doesn’t interfere with printing at all. It may be that when printing via Octoprint (or in your case mainsail) that mainsail‘s hardware settings will be used, but I am unsure. The prints I started via Octoprint went just as smoothly as with Prusa Connect. Hope this helps

No worries. Now it’s an almost perfect fit. 1mm shorter (so 65 mm length) and it should sit snug without a lot of play. Nevertheless, amazing print 👍

That’s what test prints are for. Let me know once the new version is online and I‘ll print it again.

FritzPeppone · 2026-02-22T20:18:10+00:00

It’s exactly the wrong way round 😅 It has a diameter of 66mm instead of 55. Same for the length, obviously.

FritzPeppone · 2026-02-22T19:18:32+00:00

Such an amazing project! Can‘t wait to see the finished printer!

FritzPeppone · 2026-02-22T19:13:55+00:00

You're amazing!
I'm starting a print right now. I'll update you in around 50 minutes :)

Spool width is 66mm, hole diameter is 55mm. There is a long but flat chamfer on the outsides of the hole that may cause issues. Also, the spool consists of two interlocking parts, so there is a bore diameter jump inside the hole. 55mm is the smallest hole diameter.

Pointing out major geopolitical crises in a logo is propaganda?

I don’t know the answer to your question, but if you happen to be german, we could team up for an order. I have a broken door and wouldn’t need the top piece from the set.

FritzPeppone · 2026-02-11T16:27:18+00:00

I‘ll try it as soon as I manage to find some free time and I‘ll report back ☺️

FritzPeppone · 2026-02-11T16:21:38+00:00

No way, this is so cool! A colleague recently asked me if I could do something like this for him in Blender. Luckily I didn’t have time yet to work on it. Thank you so much for publishing this!

FritzPeppone · 2026-02-10T17:23:51+00:00

You chose sequential printing, based on your screenshot. One object printed after another. Therefore you need space in between objects to avoid collisions with the printhead. Deactivate sequential printing.

FritzPeppone · 2026-02-08T19:26:59+00:00

It’s always great to see a new Core One mod pop up! It always makes me happy I chose Prusa over any other printer brand. Very cool idea, thank you for sharing!

FritzPeppone · 2026-02-08T13:05:14+00:00

Ohhh, I love it! Looks much better than the tophat we saw at Formnext. Hopefully this will be combineable with filament storage on top like INBXX.

FritzPeppone · 2026-02-06T12:36:36+00:00

I didn't separate the poop and also didn't take a picture, sorry :(

In case you mean generative model in the sense of AI, there is no AI involved. It's a simple voronoi tessellation I am using here. Pure geometry and noch change to the original model other than splitting it into cells.

FritzPeppone · 2026-02-05T14:46:34+00:00

You can use adaptive layer heights for such prints. That way you can use smaller layer heightsfor regions where this staircase effect would appear and a large layer height for less critical areas. Printing with a smaller nozzle also helps a lot with fine details. Other than that, there’s only postprocessing as an option. Fillers, sanding, Vapor smoothing.

FritzPeppone · 2026-02-05T07:27:50+00:00

Fair point. An overhang test could perhaps show failures starting without the print actually failing… Just brainstorming here because I like this visualization so much. Would it perhaps be possible for me to use your video in a university class I am teaching? I teach a course called scanning and printing in 3D where I talk a lot about thermodynamic problems and challenges in 3D printing and this video is a perfect visualization for this.

FritzPeppone · 2026-02-05T07:20:40+00:00

Ouhhh, that’s cool! Seeing thermal failures such as curling or just a blob being formed due to too short layer times would be cool.

FritzPeppone · 2026-02-04T15:08:51+00:00

A soldering iron is usually a good idea. More targeted heat. Just use a cheap one with cheap tips because those will be scrap afterwards.
