Differences between Marlin and RepRap firmware
This is a bit off topic but since I don't know where to go for the answer, I was wondering whether the firmware experts on this forum would know.
One of the things that has been brought up on these forums (for both the MK2 and MK3 printers) is the desire to have the printer electronics be upgraded to newer, faster, better 32bit processors. This sparked my interest and I went off reading about such controllers. That's when I found the DuetWifi. It has a nice and modern 32bit ARM Cortex core, 5 TMC drivers, support for multiple extruders (which could be useful for the MMU) and is expandable.
The problem is that it runs the RepRap firmware and the current Prusa electronics run the Marlin firmware. As far as I understand, the both have the same roots. However, is that true and if so, how close are they?
