CRNudo

I've seen some posts about how Cura doesn't let you change materials/colors (using the material station) in the middle of a print, thus unable to print multiple colors. Yes, it would take more time to switch colors, but I still wish this was an option. My other question though, is how come you are not able to put the other AA 0.4 print core in extruder 2 and print two colors of PLA (for example) on the same print? The Cura software allows me to select both extruders with the AA 0.4 print core and lets me choose both PLA (different colors), and it even loads both the colors into the extruders. Only when the calibration starts it errors saying the nozzles are at different heights. Is there a way to adjust the height of the 2nd extruder with the AA 0.4 core so it won't error? Is there a better way to allow both extruders to dual extrude PLA using both AA 0.4 cores?
