I am new to using the RADDS DUE and wanted to start some discussion about the best firmware/software you all use and tricks/good things to know. Thanks.
I've been using RepRapFirmware for a long time without problems. I'd recommend it particularly if you're using a delta and don't need an LCD (I use Octoprint).
My main option is repetier, is an rock solid firmware. But other options are very good too.
