3dpBurner Laser Calibration Tool

thingiverse

A straightforward tool for fine-tuning the focus of your laser etcher. Some entry-level machines struggle with powder-coated metals or glass, so it's crucial to ensure the focal length is spot-on. To get started, set your machine to the center of its calibration ramp, place a cardstock strip on the ramp, and run a quick calibration cut. Take a look at where the laser marked the paper - a perfectly centered mark on the calibration strip is what you're aiming for.
