Home Switch Problem

[Kev2960]

Hi John. There is a 24v which I think is for fan and 5v which is for the drivers. I've been playing around with it all night but still no joy. Just a silly question but should the switches be carrying voltage ? Because mine aren't

There should be voltage at the switch, which makes me think you've not got the board powered correctly.

What power supply do you have connected to the board?
And do you have a link to any kind of manual for the board?

yes ,
you should measure a voltage across an open limit switch wires

about 4V if the input circuit has a 5V supply
