I configured Simlify3Dfor my new R1+. Wow! I will post my RoBot Chassis soon. I printed the side panels with both mattercontrol and simplify.. what a difference. The interlocking notches on my print don't need rework on the simplify3d side and the glass side of the print is ultra smooth. The prints take just about the entire print volume. I am printing the upper panels and lower panels tonight. When complete I will have a ROS controlled Rover.
