Set/Recall Work XYZ using physical buttons.

Handiwork7

I've wired up to buttons which will call trigger10.g and trigger11.g

First button is to set the current work XYZ position and the second is to recall/goto the work XYZ position.

How can I achieve this in gcode? I've been using G60 but does not seem to be doing anything.

I think you're on the right track with the G60 command. You don't provide any details of the trigger macros, so the rest of this post is just guessing on my part...

I assume you've read this page on setting up triggers: https://docs.duet3d.com/en/User_manual/Tuning/Triggers, and that you've set up the inputs for the two buttons using M950, and also defined triggers numbered 10 and 11 using M581. Also, you've got these commands in your config.g file so they'll be executed every time you start the machine.

The trigger10.g macro should need only one command.

;trigger10.g
G60 S3

When this macro runs it will save the current machine location into slot #3.

The trigger11.g macro should looks something like this:

;trigger11.g
G0  R3 X0 Y0 Z0

This commands a fast move to the stored S3 location without any offset in the X,Y,or Z positions stored in S3. If you don't have the X0 Y0 Z0 in your command, those axes won't be moved (it will look like nothing has happened when you push the second button).

An additional thing to consider in your trigger 11.g macro. If your "move to" button is pressed before the "save position" button, the default coordinates stored in slot S3 are 0,0,0 so you'll drive a move you might not want. If you are unlikely to ever save 0,0,0 with your "save location" button, you could write an IF statement into your trigger11.g macro to look at the current values saved in this slot and if they are all 0, you could do something like post a message and not make the move.

To test your trigger10.g macro without the buttons, you can send M98 P"trigger10.g" in the Web control window, then send echo state.restorePoints[3].coords to see the saved coordinates. You can also look at the object model plugin to see if the location has been stored. It will be in state > restorePoints >3

You can similarly test trigger11.g. After running trigger10, move the machine using the Web control then send M98 P"trigger11.g" in the Web control window. Your machine should move back to the stored position.

You can also test the inputs by looking at the inputs section of the object model while you press the buttons.
