3dpBurner Laser Calibration Tool

thingiverse

A simple tool for adjusting the focus of your laser etcher. Some low power etchers have a hard time with powder coated metal, or glass, so making sure the focal length is perfectly focused is important. Set your height to the center of the ramp, place a cardstock strip on the calibration ramp, run a fast calibration cut and look at where the laser marked the paper. A centered mark on the calibration strip is what you are looking for.
