Creality Laser Module Installation on Ender - 3

The lazer is a great attachment but I think buying the creality lazer and engraving machine is a started choice. Still an amazing unit tho

Hi I see you have a laser dot, how are you getting that. I changed settings in lightburn to enable it but nothing shows.

Does this work for the original Ender 3?

Does anyone know why the laser stays on without me giving instructions?
