 6. If you use volumetric extrusion (M200 D2.85) then note that unlike the current edge, G1 E5 will extrude 5mm³ not 5mm. Note that in slic3r there is now a smootheware flavor you need to select for gcode generation, which fixes an issue with firmware retract.
 
+7. if you have configured more than 2 extruders you will need to recompile and set ```MAX_ROBOT_ACTUATORS``` accordingly.. https://github.com/Smoothieware/Smoothieware/blob/edge/src/modules/robot/ActuatorCoordinates.h#L17
