We have motion :)

Air-cutting a 280mm circle...

There is a frightening amount of power behind those axes, I tried applying some load but even with me forcing it as much as i could it made no difference :)

Then i moved on to limit switches - X first, using inductive sensors...

My brilliant idea was to use one sensor on the moving part of the axis and have two adjustable targets, all good so far;)

Got that lot fitted and set X++, X-- and X-Home all to one input (this was the smart bit I thought)

But....

The limits work but I cannot jog off of either end - it just shows "Limit switch triggered" immediately after pressing Reset, and the home works but immediately throws a limit fault after homing.

So...

Am I correct in now thinking that I am indeed a twat and you must have TWO sensors or have I missed something simple??

These sensors seem to not flip on or off - they flicker a little as the target gets near - is this normal??


Close but no cookie yet :)


Here's the rough lash-up of my panel...
