Under extrusion when changing colours

Bambu Lab H2 Series
1

Hey guys,

I did my first multi colour test print today however noticing some under extrusion.
I was going to have the colours in my single ams but i took the advice of the software and used the dual nozzles to save time and waste.

So i loaded black in my left nozzle and kept the purple in the ams on the right with the following under extrusion results.

You can see when printing normally the model was fine - it’s def the swap.

There was no purge tower as it said i didnt need it.
What settings do you recommend adjusting to fix this issue.

Thank you

You don’t technically need a prime tower, however, without using it the print will have defects. I recommend reprinting with a prime tower.

With “it” I presume that you are referring to Bambu Studio.

But I guess you downloaded a project from Makerworld.

If the prime tower was disabled there, it might have been the person who created the project, has disabled it.
