Hi Carlos,

I couldn't find a good spot to place Z end stop, the following picture is the best I could get for now. I didn't commit these code changes to master branch because I found Z end stop assembly collided with spindle. However, you could check out code changes from https://github.com/glenchung/Cyclone-PCB-Factory/tree/z_end_stop_assembly if you want to.
