Just a quick print to test filament for multicolor printing. I made this maker coin to basically test the filament samples that I get in the monthly MakerBoxes. It takes about an hour to two to print, depending on how many colors are tested and is a good test of the MMU2 settings for the filaments.
I also included a single color version of the coin.
This is a pretty easy print. I print with no supports to test the bridging of the filaments, but if you wish to have a better-looking bottom of the coin then I recommend using supports.
I included my Gcode if you wish to try out my filament settings for the MMU2, I know that people have had a lot of issues trying to get the settings correct. I've had great success with the settings that I have now. I used the stock MK3S Prusa profiles for the Print Settings (0.20mm Quality MK3), and stock Printer settings (Original Prusa i3 MK3S MMU2S).
The Gcode is set up for testing all 5 color slots. The main coin is in filament slot 1, the Ribs are slot 2, the Tube and Nozzle are slot 3, the Block is slot 4, and the little filament strip is slot 5.
My PLA temps are 230 for the first layer (had adhesion issues with textured bed, and this temp seems to help), and 200c for the rest of the layers, bed temp is set to 70, also because of adhesion issues.
If you do try out the Gcode and like how it worked and wish to know a breakdown of my MMU2 settings let me know in the comments and I'll post them. At this point, I'm not sure if anyone will be interested so won't take the time to post them now.
