Hello!
My name is Martin and i'm french newbie, so don't focus on my written english 
I built my printer and i consider it to be the easy part! So, i try to make it work since 2 week, but nothing work. My understanding of G-code is really limited.
So, I have a Duet 2 Ethernet with a Duex2 Expansion board, Paneldue and a BLTouch 3.1
I used the configuration tool, but it's not really working for IDEX printer, so i followed the step of this page: https://duet3d.dozuki.com/Wiki/ConfiguringMultipleIndependentXcarriagesCartesian and i modified my G-Code.
The problem i have is that the printer start, but i can't move any axis since they are not homed. When I push home, the Z axis move down a little bit and go back from where it came.
I plug the BLtouch (White and Black on the duet2, and use the pwm3 from the duex2 for the other 3 cables.
I also install a filament sensor that i plug in the duex2 pwm4 socket, but i don't know how to configure it...
I share with you the actual G-code, but i will need a lot of help to make it work!
