Optical Tool Calibration - 3D Printer

Small Video how I calibrated my tool changer using a mirrorless camera with kit lens and macro rings. These rings are pretty bad for Makro photos because of the edge blur, but in this case, only the center has to be sharp. So macro rings will do fine for this job and the image quality is even superior to a cheap microscope. More Info and Grasshopper download on my Website: follow me @Instagram
