Ok,
So far the result I got as that all sensors are trigged if one is trigged. Then I probably did something wrong. Either in Mach 4 but most likely in the wiring.
I found the attached wiring diagram in this forum thread: https://www.cnczone.com/forums/gecko...18750-cnc.html
If I follow this wiring, will it align with how you guys would do the wiring?
The 2 things I might have skipped is,
The connection between green"earth" and and the minus of the 12 v supply.
The connection between the + terminal of the 12v supply and each 1, 2, 3, terminal with appearently a 12v led indicator In between.
