Webui or UGS, I've not decided

What happened?

I would like to know what to add to the config file to enable dual Y axis homing so that the machine squares itself every time It is homed. The 2 examples in the samples folder are not really clear.
Thanks
Mike

Please see the wiki

http://wiki.fluidnc.com/

and the examples.

If you have dual steppers and drivers on Y, you need both motor0 and motor1 sections under the y: axis section, per the examples. Each such motor section needs a separate limit switch for squaring.

[jappiemike]

I did look at the examples but there was no clear guidance for example BlackBox_X32_XYYZ-DOOR.yaml has 2 Y motors but appears to have no limit switches where as 6_pack_TMC5160_XYYZ.yaml appears to use dual switched to 1 pin. I'm just looking for some clarification. Not being rude but I have to go to work now so it'll be a while before I reply. Thanks for the answers so far.

[bdring]

The use of limit switches and squaring is optional. If you want squaring you need a homing switch for each motor.

OK, thanks for the answers, once I've fitted the extra proximity switch I'll change the config to enable it.
Cheers
