Seem my Sbase is version 1.3 so Reprap FW should work on the board. I'm tempted to try it out even though I'm quite happy with the current Marlin configuration. Still, assuming everything works properly, moving to Reprap fw would remove the need to recompile the fw every time I need to change the printer configuration. I'll lose wifi (I'm using Octoprint) so I'll need to plug in ethernet cable or buy ESP8266 and do some modifications on the board.
