Bambu AMS flushing volume gauge
Description
The default flushing volumes for AMS filament changes in Bambu Studio are quite big. This guarantees a clean print without colors washing between filament changes but also produces a big amount of waste. In order to avoid having to print multiple models and guessing the best flushing volume I designed this gauge that allows finding the best values between two filaments in one go. Before printing larger multi color models with lots of material switches, this gauge can help to reduce a lot of waste while still keeping the print clean. #Instructions# ##How to print## ###Option 1: Pre-sliced file### Put the pre-sliced “AMS flushing volumes gauge.gcode.3mf” file on the SD card of the printer and select it from the display on the printer. Pick the desired filament trays from the AMS and hit the print button. If you're working with a solid and a transparent material, use the transparent one for slot 1 as that's a little easier to read, given the bottom layer below the horizontal gauge has polluted edges from the color switch on the first layer. ###Option 2: Slice/prepare yourself### Use the “AMS flushing volumes gauge.3mf” file and open it in Bambu Studio. There are a couple of things to consider when slicing: * Keep the rotation of -45° on the z axis. This ensures the printer draws the lines in an appropriate direction to line up with the gauge. * Keep the quality settings to a 0.20mm preset, or at least keep layer height to 0.2mm and the line width of 0.42mm for the top surface. The gauge size is calculated with those values. * Open the filament flushing volumes and set the flushing volume between the 2 materials to 0. * Remove the prime tower! ##How to read## The gauge shows mm³ of material. Pick a place on the sample field where the colors are “clean enough” for your use case and use that value in the flushing volume settings. In all the filaments combinations I have, I never had a case that 500mm³ wouldn't be enough. If, for some reason your material combo requires more, you can set the flushing volumes in Bambu Studio (use the Option 2 above) to some higher value than 0 and then just add that value when reading the gauge.
