Horizontal Cantilever or Vertical Diode Laser Engraver

This is a Cantilever Laser Engraver design originally based on A different kind of build.

Cost should be $170-$200 or less if you already have some of the parts. Weight of 3D Printed parts is 7.5lbs with a print time of about 17 hours. I am using grbl firmware on a Eleksmaker mana 3 controller board with DRV8825 drivers. My build uses 1-2040x600mm Main Beam, 1-2020x600mm Back Beam, 1-2020x700mm Cantilever, 2-2060x500 Feet, 2-2060x250 Vertical Feet & 1-2020x125mm V-Slot, a 2020 gantry plate and a NEJE 6W diode laser. My burning width is 425x425mm (116.7"x16.7").

I printed my parts out of PETG. The only thing I currently might update is to cut the main plates out of aluminum.

I also attached a zip file of the files currently on the thingiverse repository. Most current files will be on thingiverse.

The main build log of this started in July 2020 & I released the first version of this in September of 2020 & recently updated the files to a more rigid & simpler design. Here is the link to my original build log of this: Cantilevered Laser Engraver - Things You've Made - V1 Engineering Forum

Here is a good example of the benefits of this design. Using my previous version with a 3d printed carriage with laser offset as much as possible, I was able to engrave one my inside deck boards within an inch of the house.

Here are some examples using engraver in Vertical configuration & with a rotary Turntable:
