G28 W Error: Failed to enable endstops

Ajith Pinninti

Please.I'ts been a week I'm unable to find the solution.

I've added an expansion board dueX5 to the duet2 wifi board. As mentioned in the documentation I've removed the connector pin to "open for X2" and added the W axis in the config file. But When I try to do homing It's getting an error message as G28 W Error: Failed to enable endstops. All my other axes X, Y, Z, U, and V work perfectly. I'm confused about why It's happened.
I've verified the dueX5 connection using the command "M115".It's well. I've tried all the different methods mentioned for this problem. Nothing solved me.
Please check my config file and suggest any solution for this problem.

whenever I'm pressing homeW in the web interface Z position is changing as in the 1st line of code in homeW.g. But after that nothing worked and the resulting G28 W Error: Failed to enable endstops.

Here I'm leaving my homeX.g file and HomeX is working.

Try duex.e2stop as the pin name.

@Ajith-Pinninti can you paste the output from the following?
M98 P"config.g"

i also wouldn't be running at this many microsteps. x16 or x32 is sufficient. you will be overloading the MCU when you start running fast prints
