Problem: X and Z axis endstops wired in series together
Hello, I have just started using Duet 2 WiFi with STEPCRAFT CNC router.
The problem is that STEPCRAFT is equiped with microswitch endstops wired in series together for both X and Z axis see fig. below.
STEPCRAFT when referencing ( going to zero position ) with its original control board knows which stepper ( X or Z ) is running and then when endstop ( X or Z ) is triggered there is zero position for either X or Z axis.
Do you have any clue how this endstops common connection could be configured in case of Duet?
Thanks for any help ( I am not very skilled in G-codes )

@uca I dont't one. One way is when you home one, make sure the other isn't triggered. For example: in the homeall.g file: home x, move x away from the endstop so it's not triggered, home z. Just put a move away form the endstop for one, to use the other. You may have to connect them to both endstop connectors until the firmware can freely assign endstops.

You can use them as external triggers and put in macro whatever you want them to do. Look at https://duet3d.dozuki.com/Wiki/Gcode#Section_M581_Configure_external_trigger
@stephen6309 ooooh, so easy solution and it's working perfectly. Why I did not figure this out myself? I'll try next time.
Anyway, this was my first question on this forum and I am sure it's not the last one. I still have a long way to go.
Thanks for cooperation
@aidar perfect, anyway now I am using Stephens6309 solution.
Thanks a lot also
