I got a silent 4.2.7 mainboard for my ender 3 pro a few months ago and was running some standard marlin firmware and everything was great. I recently modified my printer to be 400x400x500 and when running the old firmware it was still silent but I finally got around to updating the firmware for the new print size using this site, reference code 9ede590c, and now the z stepper motors are back to their normal noisy selves. anybody know why this is or how I can fix it? Thank you!
