Wow, there's alot more to these then I every would have thought. Maybe I need to ask the question in a simpler way (so I can understand). I want to wire up limits for the x, y & Z axis. I will be purchasing Gecko G203v drivers and a CNC4PC- C1G Parallel port interface card. I plan to control all of this with Mach 3.
1. Should I use NO or NC contacts on the limits?
2. Should I run a pair of wires to each (axis) set of of limits. I assume each (axis) set of limits should be connected in series, however I would like to use one limit on each axis as my home switches also.
3. Should the wires be shielded?
4. Should all the limits share a common GND? If so, should this GND be bonded to the metal frame of the machine?
5. Can I use proximity switches on one of the axis?
Thanks in advance for all your help!
