[Emc-users] Combined limit/home switch

[Marco <li...@ho...>]

Hi,

I've got my basic setup working and have made some cuts. Time to add
the limit switches. For now, I've added one switch on Z+. This
should act as a limit and homing switch. It's sort-of working but…

When I'm homing the Z axes (joint 2), the machine correctly moves
towards the switch, the machine stops and I get:

  joint 2 on limit switch error
  emc/task/taskintf.cc 976: Error on joint 2, command number 95

So this doesn't seem correct. It appears that it acts mainly as a
limit switch and doesn't quite double-up as homing switch. Likely
due to misconfiguration on my side.

I also observed that it shuts off all movement, not only movement
towards Z+ if the switch triggers. Not sure if that's by design or
another sign of misconfiguration.

I've read

  https://linuxcnc.org/docs/html/config/ini-homing.html

but frankly, that's a lot to digest. Find my configuration attached.
What do I need to change so I can use this single switch for homing
as well as a limit switch?
