It almost looks like the recycled filament is softer than regular PETG and I even reduced the extruder tension, which did not help. Interestingly, the print looks perfectly fine, until after several layers it simply stops extruding.

We have several spools of regular Prusament PETG (which so far always worked flawlessly) at hand, which I could test too... But before I do more tests, I wanted to ask here first if ...

• someone had similar problems with PETG Recycled Black too?
• this could be a sign of moist filament? (i.e., these problems started only after the spool was several days in room-air)
• this could be some issue with clogging I'm not aware of? (after unloading and loading the filament it extrudes fine)

I also noticed during filament purging that the flow was not "straight down" but it would immediately curl to the front and stick to the nozzle. Is there maybe something blocking the nozzle and thus after some time the nozzle cloggs up and the extruder can grind down the filament?

I am new in printing and have a Prusa Mini.

It has worked fine until recently. I have printed 6 different items that all worked fine.

Now the printer is having difficulties in putting the first layer smooth.

At different places on the surface it makes 'dents' while placing the first layer, it quite random where but it seems that if one stretch of PLA is having a dent then the next stretch also get a dent the same place. You can see it on the first picture lower left.

This time I decided to let it continue even though it wasn't nice and I left the printer (for too long) and was busy doing other stuff and the printer failed completly and 

1. Ditched the baseplate and ejected it onto the table 2. A big blob filled the extruder. following pictures ☹️ 

I had cleaned the baseplate with soap and water beforehand and I had baked the PLA for 2 hours at 60 degreess celsius to get rid of potential moist.

So: What went wrong? and How can I get the printer working again?

Sorry for being an a.. at printing....

Ich versuche, mittlerweile seit vielen Wochen eine “Pferde Statur“ zu drucken.

Das Tierchen hat auf meinem Prusa XL Abmessungen von: 352mm in der X-Achse, 98mm in der Z-Achse und 314mm in der Z-Achse.

Als Filament nutze ich TINMORRY Glasfaserverstärktes PETG diese PETG-GF Frosted Grey oder White oder auch Black hat den Vorteil das die fertig gedruckte “Pferde Statur“ eine sehr fein strukturierte Oberfläche bekommt. Fast wie 1000 Schmirgelpapier, das kaschiert einzelner Layer Schichten und ist absolut ohne jeden Glanz (so wie ich es möchte) Ich drucke das Pferd mit einer Schichthohe von 0,1mm und mit drei Perimetern (Wandschichten).

Das Problem, das sich nicht lösen last ist der Bauch (die Unterseite des Pferdes). Dieser lässt sich am ehesten als eine sehr flachen Halbkugel beschreiben (Wölbung nach unten). Die Oberseite des Pferdes die ja auch eine sehr Organische Form ist die sich ebenfalls als eine sehr flachen Halbkugel beschreiben lässt (Wölbung nach oben), bekommt dank der Schichthohe von 0,1mm und dadurch, dass ich die Einstellung - Oberes massiven Infill – von 0,45mm auf 0,24mm reduziere eine ziemlich perfekte Oberfläche.

Was muss ich in den Slicer Einstellungen andern damit der “Pferdebauch“ auch eine so glatte Fläche bekommt wie die Oberseite.

I'd like to share Prusa StatusBar 1.0, a native macOS application I've built to make day-to-day Prusa monitoring and control as frictionless as possible.

The idea behind it

Zero clicks: a quick look at the macOS menu bar shows what the printer is doing, progress, ETA, state, without opening anything.

One click: the dropdown opens a small dashboard with everything I'd otherwise have to open a browser, PrusaSlicer or my phone for: live camera, controls, full status and quick actions.

What's in it

• Live status in the menu bar: job, progress %, ETA, bed/hotend temps, printer state
• Native macOS notifications out of the box (print finished, failed, paused, filament runout, etc.)
• One-click dashboard with live camera preview
• Printer actions: pause, resume, cancel, start
• Home Automation integration with fully customizable buttons: trigger your own webhooks or scripts to integrate with Home Assistant, Homebridge, smart plugs, ventilation, lighting, etc.

Compatibility

• macOS: Apple Silicon and Intel
• Any Prusa printer with PrusaLink enabled (MK4 / MK4S / MK3.5 / MK3.9 / MINI / MINI+ / XL / CORE One)
• Fully local: communication happens directly with the printer on your LAN. No cloud account, no telemetry.

Native and lightweight

The application is written natively for macOS, so memory and CPU footprint stay minimal. You can leave it running all day without noticing it.

Download and source

• Repository, releases and installation: https://github.com/deimosfr/Prusa-StatusBar
• Free and open source (MIT)

If you run into a bug or want to suggest a feature, please open an issue on GitHub. Print users and home-automation enthusiast, I'd love to hear how the custom-button integration works for your setup.

Thanks, and happy printing!

I'm using the 0.10mm FAST DETAIL Print settings and the Prusament PLA Filament setting, and have used the same nozzle that came on the pre-assembled COREONE L.

Any thoughts or help would be hugely appreciated.

When assembling the MK4S Nextruder, I could not find the spacer in step 19  (rightmost part in Figure on page 85 in original-prusa-mk4s-kit-assembly_2167_en_2025-09-26.pdf document). Therefore I assembled the nextruder without it. Later I found it stuck with some parts and now I am wondering how critical the spacer is because I would not like to do the tedious disassembly with the possibility to do more harm than good. So please can someone enlight me!

I wanted to share an issue I had with my Prusa MK4S in case it helps someone else troubleshoot a similar problem.

I started hearing a repeated clicking sound coming from the extruder gear during printing. At first, I thought it was related to a clog, so I started troubleshooting with a cold pull procedure. The cold pull improved things slightly, but the clicking sound continued.

After opening the extruder assembly, I discovered that the printed part called the “main-plate on the heatsink” was broken.

The broken part was causing poor alignment inside the extruder, which eventually led to nozzle clogging and the clicking noise from the gear.

Luckily, I still have my old Prusa MK3, so I used it to print a replacement part. After replacing the broken main-plate, I repeated the cold pull process again, and this time the problem was completely solved. The printer is now working normally with no more clicking sounds.

Hopefully this helps anyone experiencing unexplained clicking noises from the MK4S extruder. It may not always be just a simple clog or tension issue — it could also be a damaged printed structural part inside the extruder assembly.
