Proximity Switches

[CraftyGeek]

Thanks, i'm liking the look of this approach & I have basic electronics knowledge with plenty of soldering experience so should be easy enough to get them running - any chance of a pic showing how you've got one attached to your machine?

What are you using for limits?

limits switches are for girls!!! the 'limit' is where the ballnut slams into the bearing housing

no pictures im afraid, however they are very simple... wave something metal infront of it... and it triggers

. . . .Ah ah obviously not bent a ballscrew yet Matt or ripped the teeth of a timing Belt..

Crafty Just buy some cheap-ish micro switches for limits and wire in series. Also arrange them so they get triggered by running over the switch and not into it. Same goes for Home/Proximity switches.

Also If you want to keep wiring and number of switches down then just have 1 limit switch per axis that travels with that Axis and gets tripped by some fixed but adjustable brackets at each end.

That's pretty much what I did on my last crappy MDF machine...although the micro switches were a smidge too cheap
They've been retired...i'll be getting some new ones when the time comes.
