After I got some magic smoke from my good old GT2650 board from the modded Prusa I3 B pro (which is a dual extruding I3C pro version now) there had to be made some decisions:
Replace the old board with a new one or take a more recent faster version? Replace the old MK8 direct drive extrudes with some more reliable ones? Two stepper motors plus extrudres are heavy weight and make the x-axis very slow. So the decision was made quickly and all parts have been updated now.

My Prusa is running with Smartramps for Due now -> http://www.reprap.org/wiki/SMART_RAMPS

The old MK8 direct drive extrudes have been replaced with two of these great Saint flint extruders from here -> https://www.thingiverse.com/thing:979113 and actually I am experimenting with the brand new Carboinoid 4 color filament switch from here -> https://github.com/grainiac/Carbonoid/tree/master/fila_switch

If that all is going to work  as it should, my Prusa is ready to print more parts for the InMOOV project with much higher quality 😉

Thanks a lot to all those who developed these parts and put the sources online!
