Please see attached photo. I've got some weird diagonal distortions on a print I'm trying to get out. This same print looks great when I output it on my MK4. The orientation of the part in this photo is how it sits on the bed. This iI've tried re-calibrating the XY belts, and that didn't solve it.  Before I start burning more filament trying extrusion % and flow settings, I was wondering if there is any wisdom that could help me narrow it down.

I'm using the following settings:

- Prusa Slicer 2.9.4
- Firmware 6.5.3
- .15mm Structural
- Jessie PLA (using the Prusa provided settings for that filament)
- Prusa textured sheet

Many thanks!

Ich habe jetzt leider schon mehrfach das Problem gehabt, dass der Drucker (MK4S mit MMU) nach gewisser Zeit (6% bis 35%) einfach pausiert "Parke".

Egal ob in der App oder am Drucker, er lässt sich nicht neu laden oder sonst wie weiter nutzen. Geht nur Reset. Leider dann der Druck zum Verwerfen.

Würde mich um Antwort und Hilfe freuen.

I've been trying to print a fairly simple 2x3 Gridfinity bin in PETG, but I can't get rid of the warping that occurs during cooldown.

My setup:

• Prusa Core One+
• Prusament PETG (tested Orange, White, and Anthracite), dried
• Satin sheet

The print itself goes perfectly. The issue only starts once the bed turns off. During the cooldown phase, the edges of the part lift and warp upward. I even switched to PLA on the smooth sheet to rule out the filament, but the result is the same.

What I've tried so far:

• PLA instead of PETG, on both smooth and satin sheets
• Cleaning the plates with fragrance-free dish soap and hot water
• Bed temperature sweep from 55°C to 90°C in 5°C steps
• Nozzle temperature sweep from 240°C to 265°C in 5°C steps
• 3D Lac on the bed
• Reducing print speed to 80 mm/s and 40 mm/s to let temperatures stabilize
• Printing with the door open and closed
• Covering the printer with a blanket after the print finished
• A custom G-code that ramps the bed down by 5°C every 5 minutes post-print

At this point I'm out of ideas. It's such a simple part... any suggestions would be hugely appreciated.
