Layer change detection job.layer

[amimafe]

Hi,

I have been editing daemon.g to save several values during printing in a .csv file.
I have managed to get it to work correctly and it saves them according to the time I set with the G4 command.
What I want to do now is to save the variables once per layer. I have been testing with the object "job.layer" but I have not been able to do it.
Could you give me a solution?
I have thought to create a macro that is executed in each layer change calling it from the laminator, but I would like more to execute it from daemon.g

Thanks

All of the slicers I have used have a place to put user code to be called on layer changes.

This is a screen shot from Prusa showing where the code can go:

@amimafe the job.layer value should work provided that the GCode file has layer number comments within it. This is a configurable option in some slicers. However, some slicers use variable layer height and in this case the concept of layer number rather breaks down.

Hi @fcwilt ,

Yes, that's the other option I had thought of, but I preferred to do it by daemon.g and if a third party manages the machine, everything is integrated with the firmware.

Thank you.

Hi @dc42 ,

I read the postRe: Job.Layer not working anymore with 3.3rc2 and wanted to do something similar. Execute a command at each layer change. Entering the layer change comment with the laminator would not be a problem.
Is there still an option? I tried to do it with creating a variable and assigning it the job.layer value to compare with its current values but it doesn't work.
The idea was to make everything more compact with the duet firmware.

Thanks again

Thank you.

Understood - but the slicer knows what is going on. How would the firmware identify a layer change?

@fcwilt

The slicers we use add a comment on the layer changes that DUET2 recognizes.

Thanks for the feedback.
