Want to etch images with your 3D printer? This inexpensive laser add on module will do the job. This video will take you step by step through wiring, calibration and gcode creation. This will leave you will a 3D printer that you can convert to a laser engraver in seconds.
This method of buck converter PWM control is suitable for fans as well.
Please heed my safety warnings by using the safety glasses at all times, having the laser unplugged when powering on the printer, and using a well ventilated room to dissipate any smoke. Watch out for kids and pets walking in too.
This is a low power laser which is why it is so cheap. If you want to spend more for a more powerful unit, engraving time will be reduced and with enough power you could cut more materials.
This unit was tested on the Creality Ender 5, but the plug should work for any Creality printer like the Ender 3 and CR-10, and most other printers as well.
