Auto level just the active print's area? Is this possible?

I was wondering if I could send commands to the RAMPS controller in my robo to auto level just the active area of the print bed rather than sampling the entire bed? Basically take 9 samples in a box around my print or just 4-5 if the print is really small. Right now i know the values are determined automatically in the firmware for the robo in the configuration section, but i was wondering if i could send the sample locations to the board to be tested and stored for use while printing the object.

 

Hmm that's a good question. I'm not familiar with a Gcode command for defining the autolevel grid. Seems like something that should be possible, but it's not really necessary since a wider plane would give a more accurate result.

 

But if there were an imperfection in that parts print area that you weren't aware of wouldn't a sample around the part/s be more accurate the area being printed?

 

Yeah glass doesn't really have imperfections, that's why people use it.

 

Just wondering. I was watching a vid on the solidoodle auto leveling and it really doesn't level, but rather corrects for height variations by adjusting for the variations on the fly with the head height to table.spacing. Does the R1 work the same?
