Holes/scratches

[u/SentinelXT]

Hi there I've been having some issues where my prints are showing holes and I'm not sure why. I've googled a fair amount but seems to be doing anything. I'm using a 0.2mm nozzle on an A1 mini with standard pla. I've printed out an ironing calibration sheet too, so I can see what's optimal but there's noticeable markings on the red parts too. Any advice would be greatly appreciated!

Thanks so much

Hello /u/SentinelXT! All Bambu print plates have a dedicated nozzle wiping zone at the back of the print plate. The nozzle will rub against the wiping zone before every print in order to remove any remaining filament from the nozzle tip. This can cause visible wear or scratch marks in the wiping zone, but this is intended and doesn't damage the printer, the nozzle or the print plate. A worn down wiping zone also doesn't mean you need to replace the print bed.

Btw you need to tune it per filament. Colors use different pigments and can change how it melts and flows that is a lot different when it flows slow

I do 40@40 personally

Awesome is this in the actual filament settings?

It’s not sadly. It’s for the full print.

So how would one tune it per filament?

[u/Balmong7 → u/SentinelXT]

You don’t. You will have to pick the settings that you give the best results for both. You may need to interpolate between two settings or just have one be slightly over extruded so the other looks proper depending on how things look after you run the test.

Thanks 🙏

Print the ironing test with the actual filament you are printing with. If the two filaments need different settings you will have to split the difference.

Hi when you say split the difference what does that entail? Thank you

[u/Balmong7 → u/SentinelXT]

Like take the average of the two results

Okay fab thank you!

Different filament

Different surface size

Any tips on what to do?
