Dual Head XY Offset Calibration Tool v2

thingiverse

Improving upon the previous calibration nozzle through a complete re-design, this tool's aim is to guide you through calibrating the XY offset for your dual print head 3D printer effectively. You can likely make an educated estimate of the print head offset on your printer from reading its documentation. In my situation, the anticipated offset would be 0 and 35 for the X and Y offset respectively. Configure this in your slicer to start with: M218 T1 X35.0 Y0.0 Next, assemble both the base and 0.2 designs using your slicer. The design assumes you will print the base with the left nozzle and the 0.2 offset tool with the right nozzle. Print this off and locate the best fitting overlaps of the top and bottom layer on each spine. The innermost overlay has an offset of 0, while the outermost has an offset of 0.8. After selecting your best overlaps, note which offsets you have selected are in the "-" (top and right) or "+" (bottom and left) domains, and make a correction to your slicer's offsets; for example: M218 T1 X35.4 Y0.6 Repeat this process with the 0.1 and 0.05 tools to fine-tune your offset calibration. Best of luck!
