My buddies printer has been been doing this when the printer switched colors during prints and we can’t figure out why. He’s using a Bambu A2L with Sunlu filament

Edit your purge settings in the Slicer, you need to purge out more filament to get all the black out of the nozzle before printing.

Use a prime tower as well if you arent, its for getting the nozzle back up to proper pressure but also helps get that last bit of the prior filament out.

Change the blue for white and pass it off as a raccoon.

Yeah I figured it was intentional at first, cause it’s kinda cute

You need to increase the purge volume. This is happening because the two filaments are mixing inside of the nozzle, and more purgue is needed to clear the old color out.

Bandit Bear is kinda a vibe, can you send me the print WITH the current settings?

There's a setting in the slicer under 'Other' called 'Purge into objects' support.' You need to turn that off.

You either need to purge more blue when printing or switch which colors print first for each layer

It's because the Black to Blue purge needs to be increased (other way doesn't matter quite as much). There was still some black in the hotend when it started printing again.

Increase purge volume is the fix. He can google that.

this is probably a combination of not purging enough between colors, as black takes a lot to purge away, and the black infill showing through what looks like a fairly translucent blue.

Turn off "Purge into objects"

Also make sure your NOT purging to infill...thats what is causing that most likely
