I'm trying to home my machine. When I hit the referance button nothing moves. Does it need to be set up some how to operate? If I enter G28, the table moves to the center, and not to the home switches. I watched the tutorials on homing and I think I have everything set right. I must be missing something. I'm hoping someone can shed some light.
Thank you

Sounds like you dont have the home switches enabled in Ports and Pins, Inputs. Only other explanation I can think of is the active state of your home switches are the wrong way so Mach thinks they are already active so wont home, you should however get a message in the ticker window at the bottom of the screen informing you of that.

Home switches are enabled in ports and pins, tried active high and active low. No message. Referance button does nothing.

Seems like you may have a bad screenset as that is the only explanation I can see for both this and your other problem.

What is the fix for that? I don't know what a screenset is.
