The Z does have 2 switches, the X and Y are only 1. They are all NC.

Craig, It's a no brainer. Two heavy duty SEALED Honeywell push switches (E-Bay dirt cheap). All ya need is a stop on the casting below the table at the center of travel. Mount your switches on the table just short of travel in each direction. They don't have to be adjustable and your done. If ya need more guidance sent me a picture and I'll whip ya a solution. Bob L

Thanks

So like he said, what is the schematic for running it this way temporarily. I also have an anilam conversion. My mill is setup with one switch. I will likely move to two but would be nice to do some testing with one.

Only wire the switch to one limit switch input for each axis. Wire it to the side that will also be the side that will home the machine. Disable the opposite side limit switch with the dip switches on the board (Allin1DC).

Setup the travel limits such that it never hits the opposite mechanical limit of travel and thus never hits the switch. (The single switch will still protect the machine since it will still change state on the other end of travel, it will just tell the machine the wrong side has been hit)

In the setup screen where you specify the home and limit switches, put 0's (Zero's) where you don't have a switch wired up.

I hope this makes sense.

Thanks XR4x4ti,

This helped me in my retrofitting.
