open builds acro laser wiring and enclosure

thingiverse

Enclosed my project for a CNC Laser-Cutter based on the Openbuilds ACRO 1050 Kit. Beside the actual kit the following material was used: 10 x 10 mm aluminum square tube as support for the X cable chain 4 mm plywood for the housing 100mm Aluflex pipe for extraction optical limit stops All parts except the handle (2x) and the housing corners (2x + 2x mirrored) and the light-proof air grille (3x) are printed once. Do not print center.stl. The cable chain is originally based on the center.stl of http://www.thingiverse.com/thing:1760952 This part is only for importing the scad file. Do not print. As cable normal flat ribbon cable was used. 8 wires width fit exactly into the chain. To use the optical limit switches I used an additional Arduino Nano to exclusively orde the signal from each axis, because I have only one input per axis at my controller and to debounce the signal.
