INTRODUCTION!!!!!! If you are having problems with distortion in dimension in your print or your parts are not coming out in the correct proportion you may be in need to re-calibrate your axis in the x y or z axis. I designed this method for myself and it has worked very well as seen in the pictures. So, hopefully it will be much easier for other makers to make their printers have great dimensional accuracy utilizing this method. THE METHOD? 1)Measure your nozzle extrusion of plastic with a caliper 2a)If you want to calibrate the z axis import in your slicer the z axis rectangle file along with the nozzle size OR 2b)If you want to calibrate the x or y axis, import in your slicer the 60mm test box with accordance to your closest nozzle size. 3) Set your layer height to .2mm layers as these files are designed to utilize specifically this layer height. 4) Slice and print the file 5) Take off of print bed and measure the desired axis in question. 6) go into the excel document and input the desired measurements according to direction. 7) repeat 2 to 5 and determine if axis is within desired parameters if not then print again until axis is at your desired tolerances. WHATS IN THE EXCEL DOCUMENT? Excel document attached is utilized to make formulas for making estimates for steps and then the 3rd chart is utilized to refine your steps to get as close to 100% accuracy as possible. HOW TO USE? As seen, there are 20 some stl files to make your life easy. As 3d printer owners, all of us have different nozzle types for different applications. Stl files support .1mm to .6mm were you measure the output plastic from your nozzle or look at your firmware to determine which size wall to use from the stl files. NOZZLE TYPES? The end of the file names are the size of the nozzle the stl file is made for. EX) if you have a .46mm nozzle use the .45mm file! DIMENSIONS FOR THE STL FILES 1) 60mm test box is 14mm high and 60mm in the x and y coordinates 2) The z axis rectangle test is 60mm high and 40mm in the x and y coordinates. I hope this helps! Any way to improve on the method please let me know thank you!!! Print Settings Printer Brand: Solidoodle Printer: Solidoodle 2 - Pro Rafts: No Supports: No Resolution: 0.2mm layer height Infill: doesn't matter, printing just a wall Notes: No support, no raft, 0.2mm layer heights unless you have a .1mm nozzle in this case use .05mm layer heights.
