Anyone know how to do a filament swap with Creality Print? I actually want to drop in a magnet at a given layer but so far I cannot get the printer to pause automatically. I found the "Change Print Color" under the infill settings but setting it to "Back List" and then putting in a layer does not seem to affect the print in any way. For the other options, it is unclear what to do after selecting "Two Color Printing". Any advice? Thanks!
