Which Type of Limit Switch

[EddyCurrent]

Ray,
Take a deep breath, chill out, and read the info posted so far.

You really need a 12V or 24V power supply to work but they can still be connected to your BOB, power supplies are not expensive. ..Clive

I do have both power supplies in my CNC cabinet, so can i refresh

Just wire them like the drawing I posted and that's the job done.

Edit: posted after supping 3 bottles of Grassmoor Dark Ale.

Here you go ray this might help. (Provided Switch can use 36V)


Don't put the switches in middle because if your on wrong side of switch when you click home then mach will never see the switch.
Mach only homes in the direction set in it's parameters IE Home NEG or Home Positive direction. So lets say you always home Negative but your already on the negative side of the switch then Mach will never see the switch and crash the limits. If you position the switches at the ends of travel then Mach will always see the switch.
Now you can still have your ZERO home position in the centre of table just you use MACH's HOME OFF(set) feature and define ZERO a set distance away from the switch. Mach will enter this amount into it's DRO so now your MACHINE coordinates will display a Negative number and when you send to Zero the table will go to the centre of travel which is MACHINE ZERO.
MACHINE ZERO won't be at the ends where table stops but the MACHINE ZERO coordinate will be in the centre of travel and all WORK coordiantes will be Referenced from this position so it works just like has if the switch was in centre.
