Not extruding enough filament during poops or bad support settings?

[Macattack99]

Hi, Everyone, This is my first time posting, I’ve only been 3D printing for about a month now.

I’m printing a three colour trophy ornament (that I created in TinkerCAD). In Bambu Studio, I used the Colour painting feature to set the colours, which are Bambu PLA Basic Black, PLA Silk+ Gold and PLA Basic Red. But during the purges between black and gold (black is also the support colour), The gold colour is murky black, and the black supports have some gold.

Have you looked at the flushing volumes?

Prepare tab in Studio where the filament pool is.

Play with the values.

Ideally, you would export your model parts (each colour) as separate files and then drag them to Studio together and agree they are the same model.

This way, you can use the object panel (in prepare tab) select the part and choose the colour. Faster, easier and colours are always accurately selected.

I’ll try exporting my next model in parts, as this is all new to me exporting it as parts I’m not sure how much overlap there should be?

Also, when I change the Support/raft base back to “Default”, it looks like it changes the support colours to match the layers, which might solve a lot of my problems for this print.

Try turning off the support filament you set and leaving it as Default.

The option you set has this drawback as you are not using it as intended.

• You have every single layer swapping back to Black, this is likely causing much of your current issues.

The option you have selected is there to let you use a material specifically designed to act as support, yours isn’t.

• Support for PLA (when using PLA)
• PETG as support (when using PLA)
• PLA as support (when using PETG)

If you use it for any of the above, use the Support/raft interface and NOT the raft base. Time will let you understand this more.

For now, set the support option back to Default.

I did have Support for PLA in the machine before, which might be why I changed Support/raft base. Thanks for the support @MalcTheOracle and I’ll try exporting my next project in parts!
