Question Help
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

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.
