I'm going to assume you want to use the limit switches as home as well.
What software are you using on the computer?
Do you want to dual home the gantry?
How many home switches do you have?
On that 5 axis BOB I have P12, P13 & P15 you would normally use for X, Y & Z limits in linuxcnc or Mach 3 you can also assign these pins in software so what matters is you're wiring matches how you assigned the pins.
If you want dual homing you can share the input as long as it's not the same axis. Needs to be set in software. You can also use the p11 tool setting as another axis.
Good good you were following Joe's Build too lol, I'm kind of the Benny Hill of mycncuk lol but with worse music and uglier women ;)

Cheers for the reply,I am using Mach3 as my software and have the machine working on it. I am at the stage of fitting the limit switches, I want to do dual homing on the gantry and keep the tool setting function.

you have 3 inputs pins and 4 inputs X, Y1, Y2, Z
Something like
P12 X
P13 Y1
P15 Z & Y2 set as shared. Since you use Z the least seems the simplest solution. Setting the pins in Mach 3 should be easy but I don't use it so you'll have to ask others.
There's a good forum for Mach 3 as well for setting up.

Bought some kit, also got a grinder and an impact driver coming.
https://www.powertoolmate.co.uk/
Got lucky they sent me the case for drill and impact driver (I only bought the drill) and then I bought the impact driver without case so it worked out.
Over £200 cheaper than buying from screwfix for the drill, batteries, saw, impact driver & grinder including the VAT.
