What I printed is a Q version of the roadblock pendant, and a normal roadblock is also provided in the file. You can print without AMS. My method is to paint the model, and then add M600 (pause code, you may need to set it according to your printer) in the filament replacement code, so that printing will automatically pause and you can manually Just change the color
If you need to print a model with more than three colors, the first way is that you can find the color changing sequence in the print preview interface and record it to perform the color changing operation. The second way is to use other peripherals. Because most printers have buzzers, I think you can add the characteristic speaker code of the corresponding consumable to the code of the consumable, so that when changing colors, you can know clearly what you want to replace. Consumables, or a prompt code on the display screen, of course it is also feasible to make the motor sound, or let the motor move to different positions to judge, I am still testing
