Hi, this newbie needs help. Have fitted limit switches and all work OK. However when I press the "ref all home " button nothing happens.The machine should go to all switches as I understand it. Any help would be appreciated.

Do you have the home switches enabled under Port & Pins -> Input Signals?

Hi, yes the switches work fine, they stop the machine and show in the diagnostics page. Its just that the ref all home won`t work !

You say they work fine and stop the machine.  That implies that they are properly enabled as "Limit" switches.  However, I believe, if they are not enabled as "Home" switches, you will see no motion when you press "Ref All".

On the Ports and Pins -> Input Signals page I mentioned before.  Are the "X Home", "Y Home" and "Z Home" enabled with valid Port and Pin numbers?

can you reference each axis on the diagnostic page

Hi, have got m1 and m2 home leds up on the diagnostic page so will not ref.ms will ref but will not stop on the switch. Must have a serious mistake in the wiring !!!

check the pin numbers aren't duplicated

Hi, have got all three axis going to ref home but not stopping on the switches.The leds are lighting up in the diagnostics page

Have you checked this, and a reload of mach may help but make sure you either save the xml or know the settings.

Sent you an e-mail with my phone number if you want to give me a call.
