Hello!
Will keep this brief this will be my first ever run at printing a large multicolor object. To top it off as I understand it I am not making it easy on myself as I will be hopping between white, dark blue, and orange almost constantly… why start off easy haha.
One of the things that was an early concern as I recall with the K2 Plus seemed to be the amount of bleed/banding particularly when going dark to light colors etc. . But since then there has been alot of software and firmware updates so I thought I would come here and ask the pros what kind of settings I should look at for the multiplier… do I need a prime tower and so on.
Honestly treat me like a 5 year old here I had to look to even figure out where the flushing volumes option was and I have zero idea if the .3 it seems to be set to by default would be adequate or if I should increase it and if so by how much etc.
Thank you in advance for anyone that has a moment to stop by and help me out with this as I really want this to come out looking good.
Wow over 800 views and no one bothered to help in 3 months… well im not here to help either. I just wanted to know did you ever figure it out or preferably have you found a guide somewhere that helps simplify it. Im not new to printing but am search for a short cut… although i realize it will be a bit hit and miss depending on actual color changes. It would be nice to have some magic numbers that are less wasteful and work most of the time without having to do hours of testing 
Personally i would make test pieces of the different swaps to see how much the bleeding effects the print and then go on from there.
Prime tower should definitely exist to make sure everything is looking good.
Try something smal and use the colors you want for the big print. With standard values . You can also look at the color gradient of the poop and based on this you can change the purge values. In my experience the standard value is a little high now for colors closer to each other. And not al filament brands are the same. I got some cheap red pla from China that need more then standard purge value to go to white. The elegoo red i got can do it with little lesser then the standard purge.
