Hello 
i don't have these printers but i'm just asking information in consideration to buy:
I saw that Neptune 4 and Pro don't have accellerometer: ELEGOO Neptune 4 Pro FDM 3D Printer
how difficult is to install it ?
i saw that have the direct port for the accellerometer on the main board: Elegoo Neptune 4 Hardware
i saw that guide where they use that port to install it: Elegoo Neptune 4 Pro - Input Shaping Guide.pdf
is there also the possibility to use an accellerometer directly from the usb port ?
