Graduated Bed Compensation
I'm curious to know if anyone has tried to implement Graduated Bed Compensation ( http://reprap.org/wiki/Graduated_bed_compensation ) on the Prusa.
I have yet to dig into the firmware code, so I'm not sure how the Z offsets are applied, my guess is that the offset in Z is based on the destination X,Y location coming out of the GCode, meaning that on rapid motions the tool tip could move through existing material if there is a 'bump' in that region of the bed. I've had long narrow structures knocked over and I suspect that this is why. Any thoughts?
I would expect that Graduated Bed Compensation would reduce this problem by creating a flat layer with no Z compensation within a short amount of Z travel.

Apparently, the bed level correction works something like this:
The black line is the bed; the red line is the nozzle movement.

Thanks, that's pretty much what I expected. When I get some time I think I might start playing with the firmware.
