First layer is perfect, but second layer fails (Prusa Core One)
Hi everyone,
I'm new to 3D printing and I could really use some help.
My Setup:
• Printer: Prusa Core One
• Filament: Prusament PLA
• Hardware: Stock 0.4mm nozzle
• Slicer: PrusaSlicer (Simple mode)
• Settings: 0.10mm "Fast Detail" profile, 15% infill.
The Issue:
My first layer comes out perfectly. However, starting from the second layer, everything goes wrong. The filament doesn't seem to adhere to the previous layer; it looks "patchy" or "streaky", and the filament eventually starts sticking to the nozzle instead of the print.
What I've tried:
• Purging the filament several times.
• Cleaning the nozzle.
• Double-checking print settings.
• Speed adjustment: I usually print at standard speed, but I even tried reducing it to 50% during the print, and it didn't change anything—the issue persists.
The Weird Part:
The models I’m struggling with are my own designs from Fusion 360. I haven't changed any settings in PrusaSlicer after importing them. Yesterday, I printed a pre-made model from the web, and it worked perfectly.
Does anyone have an idea why my own models would fail while others work fine? Could it be a mesh issue or something in my Fusion 360 export?
Thanks in advance for your help!
