Hi,
I have build a Mendel90 and its working nicely. Want to try build a Corexy ( with dual extruder )now but was wondering which Controller board to get as an upgrade from the Ramps 1.4. I got to know Marlin abit . So what board do you recommend as I also want to use a dual extruder.

Thanks

You can use two extruders with ramps 1.4.

Thanks @Mark_Rehorst , yes I like all those feature, especially not trying to adjust the current manually. What is the the Firmware support like when you need help etc.

Sailfish/Mightyboard also has good CoreXY support, stepper current set via gcode (if you use standard Botsteps instead of Pololus), and configuration via text file. Smoothie will run a little quieter than Sailfish at high speeds due to microstep pulse doubling, but has fewer heater safety features and less precise extruder control.
