I am in the process of mounting limit switches on my mill. For the X switch I removed the big pin in the center and mounted a switch and then two movable ramps on either side of the table. That way i only need one switch for both directions. First question, with I still be able to use this as a home switch as well? Second question where do I mount the switch for Y? Can i some how use just one as well or do I need two? Pictures would help if you have done this. I think Z will be no problem since you only need a limit for up travel.

Go to my picture pages:

and in your browser use the search function (usually ctrl/f) and search for "limit switch". There are a bunch of pics of various users solutions

The document: "Using Mach 3 Mill" has a lot of good basic tutorial info on machine setup and limit switches in particular.


Good Luck!

Yes I have read it. I don`t have a problem with wiring them up. But it really does not give you mounting locations on Taig mills.

The only place I have a problem with is on the Y axis. It looks like it will need two switches one in front and one in back but I have still not found a good place to mount them. :confused:

Here's picture of my 3 home switches. X,Y,Z. THis is a must have when doing repeated work. If the machine gets off for some reason I can referance all home in seconds. :D I usally do it every time I start a new part cycle that way all my parts are the same. Great for fixtures too.

I just used the roller switches from Radioshack, 10K ohm resistors, scraps of 1/16" steel 4-40 and M2 screws / nuts.

This is the X table left end. The key is to mount it so you can get 12" of travel still. The 4-40 nuts are in the slot on the table side and the plate attaches it all.

The Z axis is easy. You jsut need a longer screw to hold the switch plate, and leadscrew holder down.

The Y axis is a pain. It also has to be wired NO and C. Its closed durring operation of the mill, unlike Z and X.

I was going to do a guide or writeup for Nicks site(cartertools) a while back but i just never got the time. Maybe we can throw something together! I have the wiring diagram if needed.

Thanks for sharing ... wiring diagram would be great. My new Taig 4 axis cnc is on the way. UPS says it's in the state and should be on the porch monday!!!!

Here's the diagram/schematic I made a while back. Using the Xylotex 4 axis board. http://www.acceleratedrc.com/machine/Home_switches_diagram.jpg

Thanks guys, I installed the switches this weekend before I saw these pictures. I will post pictures of my setup shortly.

Here are the pics of my setup. I went with one switch for X with two ramps. Two switches for Y and one for Z. All switches are NC and do not move so there are no wires to drag around.

Nice! I like the way you mounted the Y axis switch.

Thanks, i hope this will help anyone else with a Taig trying to mount switches.

Does anyone have any bright ideas about how to make their limit switches chips and coolant proof? I am quite tempted by Industrial Hobbies solution :

but it looks like a fair bit of work if you have to DIY the optical-limit switches.

It looks like you can use a similar housing as theres, but might need two switches in the housing. Turn the ramps around if you used them before and use drill blanks with a shaft collar to mount a spring reset the switch once it has moved away from the stop. Let me know if you don't see where I'm headed with this.

On my setup the Z is no problem of course, the y switch is covered by the rubber shield and I am installing a thin rubber cover over the X switch until I make a permanent case for it.

Cheers - I think for my purposes it'll be easier to make my switches chip/drip resistant.

Man, I LOVE the simplicity of those little pushbutton switches! I've been wanting to wire up limit switches for my Taig for a while - think I just found the way I'm going to do it!!
