I take it!
Glad it works now.

Thank you!

Notice in your U homing file the G1 commands. Lines 7 and 9 should be G1 H1.

That did the trick!

But can you explain why that is? It was H2 in stall detection and I neither understand why it accepts H1 while unhomed nor why it makes a difference triggering the endstop.

I should have asked earlier. I was working on that for about week!

@domenili Please post your firmware version (send M115 and post response), your full config.g (so we can see how the axes are mapped) and the homing file that causes the behaviour (eg homeall.g).

Even though M119 reports "U: at max endstop" when I feed positive into the endstop

Do you mean when you press the endstop switch? Does it report "U: not stopped" when you let go of the endstop?

Ian

It reports "not stopped" when it's not triggered, and "at max enstop when it is". I bought an endstop with an led to verify the right values at sight.

M574 U2 S1 P"!io3.in" ; configure NC-Endstop for U-Axis on low end

Try this:

M574 U2 S1 P"^io3.in"

It tried that, but the behaviour was exactly reversed.

Config and homeU are attached. Afaik the definition of the endstops is made in config and the homes just take the configured pins right? Because I made no changes at all to the home-files since I switched the endstop.

Hey folks,

I'm new to this forum and trying to solve a problem I'm in for a while now.
I try to construct a 4-axis-printer and try to home the 4th axis with an endswitch instead of stall detection like the other axis.

Even though M119 reports "U: at max endstop" when I feed positive into the endstop, it doesn't stop and crunches into stall until the movement completed.

; Endstops
M574 X1 S3 ; configure sensorless endstop for low end on X
M574 Y1 S3 ; configure sensorless endstop for low end on Y
M574 Z1 S3 ; configure sensorless endstop for low end on Z
M574 U2 S1 P"!io3.in" ; configure NC-Endstop for U-Axis on low end

Are there any recommendations? Stall detection worked fine.

Much thanks in advance!
