I don’t know about you guys, but I’ve had a little trouble getting my bed level. It can be pretty hard to tell what parts need to be raised, and what parts need to be lowered. So I wrote a script to tell me! Well, two scripts. (https://github.com/DavidAA/bedHeightMap)
One to generate a Gcode script based on your preferences and printer, and one to analyze the log file and output a greyscale image based on the height data it found with the Gcode script. Needs Python 2.7 and the Pillow module, unfortunately, plus I only tested it with Repetier Host. But hey, maybe someone’ll find it useful. The output is, once again, an image of your bed with one pixel for each time the printer checked the bed height. The more intense the brightness on the image, the higher your bed is in that area. A completely black or completely white pixel means it’s too far/close to map correctly onto the image. The top left of the image corresponds to the 0mm, 0mm corner of your bed, and the bottom right to the 100mm, 100mm corner. (Or however large your print bed is.)
Anyway, thought I might put this out here, in case anybody needed/wanted it.
