[title] Gather Information About Your Printer
[* black] Before we can properly configure the Duet with RepRapFirmware, we must gather a list of parameters that define the mechanical operation of the printer itself. This information can be found in multiple places and will vary from printer to printer.
[* black] In the case of the Ender 3 Pro, Creality provides a download for the Marlin configuration used. You can download the Creality Ender 3 Marlin Config here:
[* black] The SD card that came with your printer may also include a copy of the Marlin files. The Marlin file we require is Configuration.h.
[* black] Some of this information can also be accessed via the LCD menu on the printer if you already have it up and running.
