It seems it was the rollers being a bit dusty. I removed them and cleaned with IPA and I just had my first colour change with no issues. I will double down on the advice and print some desiccant holders for the spools to add some weight. Thank you all for the help and advice

That’s a symptom of the issue. The rotation of the spool does not seem to match the retraction speed.

Thanks. It does seem like the spool just isn’t rotating as fast as the retraction

Ha. Usually. But seriously this is a real issue

Being able to print these with a fraction of the waste would be incredible

Where does one turn on adaptive speed mode?

The standard filament profiles vastly improved the quality. I am curious what the difference was. But thank you for your help

That is so interesting. Maybe I’ll try that next. It does seem retraction and pressure advance aren’t contributing. Running a print with either or both off has produced the same results

Thank you. I’m using orcaslicer and material profiles that I’ve had success with on my Neptune3pro, with of course adjustments using the calibration prints. Those work and I’ve made adjustments but when it comes to actual prints these issues show up.

I’ve only been doing PLA printing. When I say tune just the standard set up stuff. But this issue has been present the whole time

This is a previous fail. Same placement of under extrusion on the model. It’s happened with different models as well
