HI guys,
I am currently building a homemade CNC mill from scratch and am learning quiet a bit on all aspects. I have retrofitted 3 axis from unused equipment with step motors controlled by a micro driver. I am using KCAM, and just last night downloaded MACH3.
I was curious as to if I need limit switches or not. I noticed that in KCAM you can tell the computer how long each axis is, which I figured would be the equivalent of having limit switches. Do I still need limit switches or E-stops, and why?
THANK YOU
MAX
