History

I had installed LED lights on my X1C, using a 6-Pin cable to access the 24v provided by the printer to the AMS unit (by plugging it into the second AMS 6-Pin port).  That worked great when I only had one AMS, but the cable length became a concern when I added my second AMS.

I designed a Power Tap box with a 6-pin connector to draw 24v from the 4-pin Bambus Bus Cable.  I then added a USB Board to the STL design to provide additional options in the future.
