Saving machine settings between sessions

[JAZZCNC]

Interesting demo, Jazz! Better than +-0.01mm repeatability, which is better than I would have expected. You look as if you are bringing the ballscrew towards the sensor from the side, and maybe it would be even better if you came at it end-on?

Well possibly but it's not a good idea because you can smash into them so it's always better to slide by.! . . . But yes although I knew they where more than good enough for a router I was quite surprised and before the Video I'd done loads of tests on each axis just to be sure and they where all about the same so consistant repeatabilty across the differant switches.!!

If you look at the video around 4.02 mark you'll see another switch that is the traveling limit switch for X axis and at 4.08 you'll see the washer that is the target.!
This way I can adjust the limit distance by moving the target and keep the wires/switches to a minimum.
