Setting Z Offset
-
I am using the Duet 3 board (Firmware 3.0). I am trying to save my Z offset as 1.7 using the code M851 Z1.7. However, when I check with M503 I get this:
G31 P500 X-38 Y0 Z2.044 ; set Z probe trigger value, offset and trigger height. It will not update. Please advise. Thanks.

Did you note the sign reversal?
Does G31 Z work properly otherwise?

@Phaedrux I tried the sign reversal. I edited the file in the web control and even updated the config file and uploaded. Yet, M503 command shows no update.

@Weevil said in Setting Z Offset:

As it shouldn't. M503 reads back the config.g.

If you want to reload the config-override.g that's M501.
You'd then have to check the current G31 by sending... G31 with no parameters.

@Phaedrux I tried it one more time and it works, sort of. Using a z offset of -1.70 it stops quite a ways from the head. I will have to re-calibrate.
