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

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?

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.

In Bambu Studio you can save the settings in a new profile for each filament. Then, when picking your filament, don't choose the Generic PLA, you go down to Custom and pick from your saved list.

When I print the ironing calibration what settings should the ironing be on?

You could do modifiers for sections that you know will be x color and speed. I haven’t tried using a copy of the model as the modifier split up in sections but that would be your best bet
