Endstop behavior

fcwilt

I was experimenting on temporarily changing the behavior of my Z endstop.

The setup of the Z endstop switch is such that it is triggered from appx Z=37 to Z=0 - which is how I designed it to work.

Normal homing is toward Z min.

I was testing to see if it would be possible to "home" toward Z max until the Z endstop was not triggered.

The normal configuration setting is M574 Z1 S1 P"io2.in"

For the test I meant to change it to M574 Z2 S1 P"!io2.in" but by mistake I changed it to M574 Z0 S1 P"!io2.in"

Now from the M574 docs there is this:

Znnn Position of Z endstop: 0 = none, 1 = low end, 2 = high end.

Oddly enough the G1 H1 move still responded to the de-activation of the endstop switch.

So what is the intended effect of setting an endstop to none since it isn't affecting the G1 H1?

Thanks much.

I think your exclamation point must be inside the quote.

Sorry that was just a typo here in my post.

It is all working as desired.

I was just curious as to the behavior when I made the mistake and had it specified as "none".

My understanding of none is just not present. But how that plays out in modern firmware I'm not sure.
