Duet WIFI will not zero accurately
-
Appreciate the info.
Interesting! Glad it it is at least working as is / today.
K - will check in tomorrow. I am on Mountain time in Colorado...
-
Just wondering if you have had a chance to look at this a little closer...
Thanks!

G30 S-2
M500 ; save resultsAs @fcwilt says, this bit doesn't do what the macro seems to want it to do.
Can you upload your config-override.g file so we can see what it has saved to it? This is the file that gets created/updated by M500.
@fcwilt said in Duet WIFI will not zero accurately:
However I think it makes more sense to use G30 S-3 which makes changes to the Z Trigger Height of the Z probe. To save that information in the config-override.g file you would need to use M500 P31.
This would be the solution. Or at least that would do more what the macro seems to be trying to do.

Sure...

; Probed tool offsets
G10 P0 Z-4.00Well you do have a negative Z offset saved in there, though I'm not sure from where. Perhaps this is part of the problem with it not zeroing accurately?
To get a better idea of what's going on in the system we'd need to see all your config and macros being run otherwise we're just guessing.
-
I can post those.
Is there a way to manually set it? I don't do it very often. If the Macro or something else is unreliable, maybe that is the way to go.
LMK - if no, will post it all.
-
Post your files and I'll have a better idea of what's going on currently.
-
Yep - long delay, but here is everything in one place...

I think your macro isn't doing what you want it to do. You're changing to the manual probe before measuring the trigger height, which is giving you a negative value, and then setting back to bltouch.
Your zeroing macro should probably look something like this instead.

Delete that from your config-override.g first

I agree - it is not
That said, I did not write it and am not familiar with G Code other than what I have learned in problem solving/tweaking - so not even familiar with the concepts.
Does what you see in the existing macro explain the erratic behavior? That has been what is most confusing.
Will send this to the person I got it from and see what he has to say, and will try to look at the code, read the definitions for the switches and see if I can make some sense out the differences, then try it out myself. I use these machines for my work and have them both going constantly for the next few days - will try to make time to experiment after that.
Thanks!
