Oh yes, one more thing - I made a mistake and created a print of two objects with the second object elevated about 9mm above the build plate. What the printer did was it did not draw a skirt for the elevated object, but when it got to the object's base height, it went over to where the object existed on the bed and deposited some filament which of course came out in a sproingy coil because there was nothing to support it. This leads me to believe that a multi-filament print can be accomplished within certain design constraints.
