I do not know what is the way how I can speed up my printing with no guality losses, if I got that Sonic Pad. If it based a Klipper, how it can help with the Marlin machines? I can use,. and I use both FW "forks" right now. I have only one printer on my bay, what use original Marlin FW. and that is CR-10 Mini. My Ender 3 v2 is already Klipperized. Well, if I get that Sonic Pad, maybe all come much clearer to me. I mean, then I maybe know better what that equipment is and what it does. Different than my favorite combination, Klipper with fluidd and KlipperScreen.
