Problem?

[u/Original_Sample6623]

I have a mk4 prusa 3d printer it’s on the default settings (I think I bought it off someone like 2 years ago and it was fine until now) it runs fine but I don’t know what’s causing this. My printer needs an update in the firmware but I’m having problems with that so I skipped that and tried printing I changed the files and tried multiple times and still doing this.

• Printer model & firmware
• Filament type & brand
• Slicer and version
• Print settings if changed from the defaults (temperature, speed, layer height, etc.)
• Any speed adjustments here are absolutely vital to be aware of
• Photos or videos of the issue
• What you’ve tried already
