Test Pattern for Multi-Color Printing

I am working out the kinks in using the Bambu Cool Superstick plate, E3D (Bambu Licensed Partner) high flow nozzle, and running multiple colors between two AMS units…. and running in Insanity mode (166%). It's a lot of fun but what I am learning, when printing in multi-color, I need to make sure the AMS units are up to speed and a simple way to do it is to perform a quick 3 layer color test. The main print is with a 0.6mm nozzle and using 0.18 layer lines.For my use, I had to set the volumetric values for PETG HF to 42 per E3D and then there are a lot of fine settings to adjust for with this nozzle to eliminate filament (poop) from being flung across the build plate. For, me, I would rather print something small and quick than to get into a print and get stuck and half to power down and recover the print after a repair which may cause the print to release from the build plate.
