I'm using a C35s BOB for my G0705 mill and want to use proximity switches like these Inductive Switch Assembly to RJ45, CNC4PC

I'm having trouble with Mach 3 seeing all switches, at the moment it will only show 1 on the -Y.
All switches came wired into a rj45 plug. All built in switch lights are on and do flash on or off when metal is placed in front of them.


Thanks

The A61 Limit/Home Switch configuration is wired in pairs, meaning X+ and X- are essentially just X, same with the Y. In Mach, you would configure the ports/pins so that X(or Y)+ and X(or Y)- pins are the same.

Per CNC4PC
"Has 7 Inductive switches (X+, X-, Y+, Y-, Z, A+, A-). The switches are connected in pairs per axis."

And if you look at the pin out:
LIMIT SWITCHES CONNECTOR
RJ45 PIN DESCRIPTION
1 GND
2 Z HOME/LIMIT
3 Y HOME/LIMIT
4 X HOME/LIMIT
5 A HOME/LIMIT
6 NOT USED
7 5V
8 NOT USED

Do you have all of the switches enabled in homing and limits?

Seems I had plugged them into the rj45-8 plug instead of #7. Mach can see all of them except --X, the switch lights up and if I place a piece of metal next to it, the light shuts off, but nothing from mach3.
