Hey Guys,

I'm having an issue with homing after upgrading to version 3.3. My machine homes all three axis successfully using the home all button but returns to "The following axes are not homed: X, Y, Z" once homing completes and the steppers are released.

My best guess is there's a command that I'm missing, but I've been unable to find it in the Gcode dictionary. I've searched for similar issues on the forum without any luck there either.

Thanks for any suggestions!

@bvi8370 can you post your homing files please. Can you also confirm your firmware version using M115

What do you mean by this?

Post your config.g as well. Do you have a idle current set to 0?

Do you mean using M18 to disable the steppers?

IF so that is the cause and it is the expected result of using M18.

During the home all process, each axes turns blue in the web console and the message "The following axes are not homed" disappears. Then there is about a 10 second delay. Then all the steppers disable (so the axis can be moved manually), and the message "The following axes are not homed: X, Y, Z" appears again. The machine doesn't remember that it just homed all the axis.

I'm not using M18 to disable the steppers. I'm just clicking the home all button in the web console.

Thanks again!

You've set the idle current to go to 0 after 10 seconds. Hence why it unhomes. Change the I value to 30

Be very careful if you do move them "manually" - moving them will generate a voltage from the stepper which can damage the stepper driver chip on the Duet.

Move them slowly - very slowly.

Thanks. I learned this the hard way when I bought my first Ender 3 a couple years ago - smoked the board instantly!
