Aluminium Extrusion Router Build

[NFryer]

Ok imagine if you rotate the sensor by 90' and put a target at each end so that the sensor slide over it to trigger.

the target would not be a the complete end but a small distance from it to enable the gantry to travel to the end before it trips. This is done at both ends.

I believe Mach can use the sensor to home (then offset the home say 1mm) once homed Mach would then set it to be a limit switch. This way you would only need three sensors with three inputs. (not sure if you have a slaved axis ie two motors)

If you have two motors to slave you would need two home switches one for each side.

Hi Clive, once you mentioned rotating the sensor by 90' I understood what you meant, it'a a nice simple way of using one sensor. Unfortunately I've already done the X axis sensors, so can't change them, but it's something to remember if I change the design once built or build another machine.
