m671 dual lead screw bed.g
-
i just finish upgrading my cr10mini with a duet wifi
and ran a g32 it did everything fine intell it got to the end of my bed.g file where i entered in the x y coordinates for example and it ends up hitting X max? if i type it in manual it stops exactly were i want it ```

here is my config with the m671 at the end, just not sure if im setting the bed.g coordinates wrong . RepRapFirmware for Duet 2 WiFi/Ethernet version 2.03```

You are asking it to probe at X=280 in the second G30 command, however the probe is offset form the nozzle by -45mm in the X direction. So that requires putting the nozzle at X325, which I presume is outside the limit of your machine. So reduce that G30 X coordinate.

You should run the G30 leadscrew levelling commands before mesh probing the bed. Otherwise, the mesh will take account of any tilt that the G30 commands remove. So move the G29 command to the end.
I didn't spot anything wrong with your config.g file.

@dc42 ok I will make it smaller I wasn’t sure if was asking for the nozzle position at 280 , so when in g30’s commands the offset of the probe is now let’s say zero
