Thank you very much for the quick response. You are a true life saver. Especially the life of the printer...
Ich modiefied the code a bit so that the head moves to the middle of the bed before probing. The rest was copy / paste. Thank you very much again. Joe

Hello Community,
I am new here in this forum. Hopefully someone can solve my headache here.
I run a core xy printer with a duet wifi 1.02 firmware 3.xxx stable.
x and y axis home with microswitch...... no problem
z axis should hime with a npn probe.
it is recornised by DWC, it switches, but when triggered durin home Z or manually the axis does not stop.
setup was done initially with te newest version of the configuration tool.
my config.g:
; Configuration file for Duet WiFi (firmware version 3.3)
; executed by the firmware on start-up

i am completely stuck, figured out problems and solutions with z28 myself,
hope someone can give a bbit support. thanks in advance,
