Multicolor print without wipe tower
I'm trying to do a print of a rock with 3-4 colors swapping every 2-3 minutes or so of printing. I don't want or need the wipe tower as I want the object to have a completely mixed color scheme kinda like tye dye. Is there a way to do this with the mmu2s?
RE: Multicolor print without wipe tower
manually cut the filament and feed in the new colour by hand!

I was hoping to automate it more as the print is going to be somewhat large. That would be a nice feature to add in at some point if there isn’t a way to do it now.
thanks!

Hi Eric,
the problem you would have is that every MMU change has to withdraw one filament and advance the next, and that is not an exact science, so you would either get gaps, or blobs at every change, which is unlikely to look good, and if it blobs you would probably get collisions, this is one point at which palette 2 would excel...

You can get close by turning on "wipe to object" and "wipe to infill" for your object, and setting the minimum tower purge volume to just the bare minimum needed to prime the nozzle.
Shameless plug - keep an eye on my and Gnat's purge bucket mod. https://forum.prusa3d.com/forum/original-prusa-i3-mmu2s-mmu2-general-discussion-announcements-and-releases/the-mmu2-purge-bucket-thread-mod-wip/
This thread inspired me to look at adding a colour randomizer feature.
RE: Multicolor print without wipe tower
The critical part is a filament change. It takes a pretty long time. If you keep the nozzle at the object, you will get a blob. If you raise the nozzle, you will get a part hanging filament. So you need to wipe a nozzle somewhere.
And as Joan mentioned, after the change there is no way to make a seamless transition. This is MMU, not Palette+ 😉

There's a proof-of-concept print in my bucket thread. I'm hoping to finish some tweaks and publish an alpha version for folks to use at some point this weekend.
