Firstly, I'm sorry if this is in the wrong category, wasn't sure if I should put this in general or firmware wish list.
I have been thinking lately about the G29 probing radius on my delta. When I am printing a 200mm by 10mm rectangle, it seems wasteful to use a 100mm radius probing circle at 10mm probe point spacing if the only area of the bed that I will print on is that 200x10 rectangle. If only there was a way that I can set a probe field that only covered the area I am printing on. I would then be able to decrease the spacing between probe points and get more probing per square cm on my part than if I use a circle of 100mm radius.
Is it feasible to make an option in the g29 command that would evaluate and probe the area only covered by the first layer? Or maybe even more parameters in the command itself that we can enter to constrain the probe area and better suit the shape of the object we are printing?
