Input shaping is a revelation in 3D printing, allowing a huge decrease in print time without a decrease in print quality. Until now it has only been available with Klipper firmware, or in a simpler version with RepRapFirmware. GH Enterprise has created a stepper motor driver with input shaping inbuilt, which means it can be used regardless of firmware or mainboard. In this video I test it out on an old 8 bit mainboard with great results, and cover limitations and other tips to get the most out of the product. The stepper drivers were supplied free of charge by GH Enterprise for the purpose of making this video. All opinions expressed are my own.
