I'm in the process of converting a MF70 to CNC control and I'd like to solicit information and maybe photos on limit switches. I'm using a CNC shield so it already has provisions for 6 limit switch inputs. My questions are how are they mounted on each axis and where. I don't want to over think the problem or reinvent the wheel. I was wondering if there is a way to place them the first try to get maximum X, Y, Z movement or do I need to provide some adjustment capabilities. I've never worked with CNC or a mill for that matter so any help the group can send will be greatly appreciated.
