Heated bed calibration

thingiverse

I use this tools for RigidBot heated bed calibration. Precondition: Use the "Heated bed spring fitting" (http://www.thingiverse.com/thing:515186/#files) to ensure that dimension and distance are equal. The procedure is than as follows: 1.) Turn off printer 2.) Move up Z-axis manually 3.) Place Z_axis_distance part on left and right side as visible on first picture. 4.) Move down Z-axis until gantry touches Z_axis_distance part 5.) Adjust all four heated bed screws until they are in one level with the build plate. 6.) Adjust the heated bed screws until Heated_bed_distance part fits between heated bed and steel rod (distance should be ~22[mm]) 7.) Perform step 6.) for all four corners of the heated bed. 8.) Step back to step 6.) multiple times until Heated_bed_distance part fits perfectly in all corners. 9.) Secure screws with corresponding nut 9.) Turn on printer 10.) Lift up Z-axis 11.) Remove Z_axis_distance parts 12.) Adjust Z-axis switch until distance between nozzle and heated bed fits your expectation
