Sorry if this is not the right thread.
Having read many threads, all recommend 6 limit switches for a gantry router/mill. One on each end.
Does anyone see any problem with single switch on each axis activated by a ramp at each end. The switches connected in series.
The switch having a roller and the ramps adjustable to set the limit positions.
I will be using Mach3 and a HobbyCNC controller
