Printed great with one AMS. Here is what I did to print five colors with a single AMS: - add a pause right before the final layer - set the print order of the final layer so that white prints first and red prints last - substitute white filament for red on the print -when the print pauses before the final layer, get the spool of red filament ready and resume the print - white should print first. when it finishes, swap the white filament for the red filament in the AMS while the rest of the print continues. only the final layer will have red filament, but there should be no bleed through so it will look fine.

Everything printed great and fits perfectly. I thought I purchased the same hydrometer from Amazon that was linked in the description, but apparently not because it sits sideways in the print. This isn’t a huge deal though. Functionally, everything works flawlessly and dropped my humidity level overnight from ~40% to 10%. the AMS which constantly displayed a dryness level of “D” now reads “A”.
