dji inspire arm lifting mechanism

thingiverse

I have redesigned the arm lifting mechanism to accommodate a brash nut for an 8mm trapezoidal lead screw (the same as many 3d printers). Also, there are holes to run the wires for the limit switches. Check out the "low-tech" wiring diagram on rcgroups for a super simple solution to wire the limit switches to the servo, no complicated stuff, just add two diodes and some wire! no arduino or anything else!http://www.rcgroups.com/forums/showthread.php?t=2327044 The rod adaptor screws to a round servo arm and the 8mm rod slides into it. You will need to use a rotary tool (dremel) to grind a flat spot onto the 8mm rod. there is a hole for a 2mm setscrew as well. the front and back parts that fit into the frame slots will need some sanding, this is done on purpose! this was to remove slop from the system.
