The 2nd extrusion system on my Ultimaker is apparently not being recognized in Cura 13.06.4 (Windows). The printer previously worked without issue, and after upgrading for dual extrusion the 1st extruder and nozzle continue to function, but not the 2nd extruder.
Furthermore, I do not see any options in Cura for selecting which nozzle to use for a given part placed into Cura (For example, in Cura 13.03 I could select a part for a different extruder, and it would show up with the different color. This is how I knew which nozzle was used for a given color of PLA).
Some of the things I have tried, but to no avail:
-closing out & restarting Cura
-closing out & restarting Windows
-complete uninstall & reinstall of both previous versions of Cura and the latest
-reinstalling the Marlin firmware, latest (v1)
-verified that no voltage is being applied to the 2nd heater block with a multimeter, but voltage (heat) is being applied to the 1st heater block
-verified that all connections correct per install instructions
-tried making a test print using Cura's option with 2nd extruder as support (Support dual extrusion); instead BOTH support and the part materials come from the first nozzle.
Please help! Thanks!
