As you have already noticed, 3D FDM printers, like the Cube3, produce a variety of sounds. Paying close attention to those sounds is more important than might be first apparent.The Cube3 and all printers of its type use stepper motors to move along the X, Y and Z axes and to control the flow of filament. More often than not, more than one stepper motor will be working at any given time so the sum total of the frequencies can produce some very elaborate sound combinations.We Can Learn What the Sounds Mean If we learn to listen closely,...
