Excluding points from mesh bed level
-
Due to the shape of my printer/toolhead, there are specific points on the bed that the probe cannot reach. However, later on down the axis it is able to reach them, so am I able to exclude points from a mesh level?
e.g. I want to mesh level from X0:200, Y0:200 s20 but exclude (0,0) and (200,0)?!

Not that I'm aware of. Moved to firmware wishlist forum.

@Dezdoghound, your bed is not convex and when duet goes in a straight line from point A to point B it may hit an obstacle. This may be a bigger problem.
One simple workaround to to limit the duet to a rectangular area.

What I've done for now is just mark out on the slicer where the unusable areas are. The mesh probe currently only does a rectangle where it isn't constrained by those points. -
I thought I remembered this was possible long ago and I checked the Wiki.

You used to be able to define the probe points on a Cartesian bed like you can with a Delta back in the 1 series firmware.
It sounds like Phaedrux thinks it might happen again some day.

this would be nice to see working again so I can avoid the location of the magnets I have under my PCB bed.
