I don’t get this. I’ve got an end stop on the maximum end of the Z axis. It’s connected as Z1.
No matter what i do, end_stop_Z1_stops = z_pos, z_neg, z_cw or z_ccw, the behaviour is always exactly the same - the endstop stops negative motion only (i.e. movement towards 0). M574 behaves in exactly the same way.
What is going on? Am i going nuts?
Hehe, let’s hope not! A clean M574 should return the current config, how does that look? Are you editing local.cfg?
M574 by itself returns the correct setup (regardless of whether i set it up via cfg or override via gcode). But the actual behaviour is always the same, no matter what it’s set to.
I’m using a custom .cfg i edited for my machine, but i’ve tried editing local.cfg as well. I’ve currently have it empty and am using just the printer-specific .cfg (sanity check).
I’ve tried Z2 as well, same behaviour.
I think i might be going crazy. Now it’s suddenly working.
Maybe i’ve had it overriden in local.cfg and forgot to restart after clearing it. No idea 
That might be it. But the M574 should give you the current config no matter what is in the config files.
Then i’ve got no idea what happened. I was moving the Z axis up and down and triggering the endstop with my finger. It would only stop the negative movement, regardless of what M574 was returning. Weird.
