Cheers everyone

I have both home and limits on my machine, but I must say after I set up the soft limits I have never hit a limit switch. If you are running servo's then I would still install limits as it would not be the first time a servo has gone AWOL which could do some serious damage.
I'm using steppers on this one but will bear that in mind for the next one. switches and soft limits! dosnt that eat up more of the travel?

Can the homing be controlled so as to only happen in one direction, as micro switches have a thickness to the control arm.
I think thats the reason mach backs of the switch.


One solution is an opto slot phototransistor and a comparator. That has no hysteresis and doesn't impede the movement.
I was tempted use a similar type from the old machine but maybe I wont know.
