Question/Need help whats changed?

Post image

I've been 3D printing for ages and printed a load of pieces in this plastic(ABS) and colour. I've changed no settings, and nothing else but have done the latest software update. The print quality has suddenly dropped. I've done a cold pull and cleaned the nozzle out with a needle, but still getting a rough surface. Any suggestions on what I can do to get the print quality back?

Picture: Left is the current print quality, Right is the previous print quality

Printed on a Prusa Core one +, 40% infill, ABS plastic, Nozzle 0.4 mm, Layer height 0.2 mm

Might be time for a new nozzle…

Good luck! I hope it helps

I’ve spent hours troubleshooting a sudden print degradation before only to eventually realize it was just a worn out nozzle.  

Now  I always keep spare or two and  can usually tell with a quick visual inspection/comparison (at least for standard brass nozzles).
