RepRap Guru Cable Chain System

thingiverse

This is for the RepRapGuru printer, which is a knock off of the Prusa i3 v2, or the Anet A8. Includes hot end bracket, x0 bracket, a bracket that is mounted over the arduino Uno, a special chain link, and the standard chain links that others have posted. This chain system manages cables from the hot end to the right stepper motor most near the x-home position on z carriage, picks up the x home switch and the x stepper cables, and brings them through a second chain to the Uno. There are two chains: one for x motion, and one for z motion, and they share a common node at the x-home position. You will need to drill 4 holes next to the Arduino Uno in order to mount the Uno bracket. Print the Uno bracket, and dry fit up to where the right corner touches the edge of the plastic support structure on which the Ardiuno is mounted. This should place the bracket roughly 1 inch below the top of the circuit board. Mark the holes and drill. I used some extra machine screws and washers left over from the build kit.
