FAQ Mach3


 

 

 



Do I need to use Home or Limit Switches?

You can run your entire machine without using a single home or limit switch.

Home switches are added to only one end of an axis, so that you can zero out your coordinate system on that position, and have a repeatable known zero every time you use your machine.

Since you have that switch there, it is usually also assigned as a limit switch (positive or negative depending on your direction of travel), but you don't need to.  This will just keep Mach from commanding your machine from going any farther in that direction.  

At that point, you can chose to install another limit switch switch on the opposite end of your axis to keep Mach from commanding your machine from going any farther in that direction.  Since this switch doesn't require generating a repeatable zero position like your home switch, this one can be much cheaper.
