iDR Laser Engraver

Description

I made this design in order to utilized my abandoned stuff. This design was inspired by ZDV Laser Engraver, https://www.thingiverse.com/thing:2703455 thanks to ZhilDV for his design For the small size laser engraver below 100 cm square, you might use 2020 aluminum extrusion, even though using 3030 V-Slot aluminum profile will produces more sturdy structure. A board from Creality Ender 3 3D printer will be used as the Controler which is Marlin based firmware instead of GRBL. Then it will has a nice LCD display and printing from microSD feature. The Laser module is 5.5 watt from this link : https://www.aliexpress.com/item/High-Power-450nm-5500mW-12V-TTL-Adjustable-Focus-Blue-Laser-Module-DIY-Laser-Engraver-Accessories-5/32855784586.html?spm=a2g0s.9042311.0.0.2edb4c4dv6uPcf Edited: Since this laser module is not available anymore on that link above, you may purchase the similar laser module with a PWM input feature suported Laser PWM signal is derived from part cooling FAN signal with M106/M107 command. Since this board uses 24V power supply, i took the 5V PWM signal from the "Gate" pin of fan mosfet, to comply with PWM laser module input voltage.
