About: "Magic is just science we don't understand yet." Let's face the obvious: yesterday we were nerds, today we're the cognitive elite. Let's conquer. Religion is what happens when people can't just accept "We're…

This instructable is for my build of CoreXY movement style laser engraver. There are a lot of instructables regarding building CNC so I will not go into details as this is not a simple build and certain knowledge of basic CNC construction and setup of electronics is expected.

CoreXY is rather interesting CNC movement style that enables the machine to be more streamlined placing x and y steppers on the same plane making it flat.

More about this style of movement can be read on corexy.com

Items needed:

2.5W laser - $128 - Any laser would do but I used this one and laser holder

2 x Nema 17 stepper motors - $13.25 x 2

3 Axis Stepper Motor Driver Board - $26.99 - You could make your own with Easystepper driver board or Using GRBL shield for Arduino

4 x LM8UU 8mm Linear Ball Bearing - $1.69 x 4

UPDATE:

I realized that there was a part missing. At the start of the project the laser carriage had standard LM8UU ball bearing but as they were cheap ones they had a LOT of play in them so the carriage was redesigned to accommodate s 8mm x 11mm x 30mm copper graphite bushing instead.

2 x 8mm x 400mm Cylinder Liner Rail - $5.49 x 2

2 x 2GT 16 Teeth Timing Pulley and 5M 2GT-6mm Belt - $9.72

8 x GT2 16 Teeth Synchronous Wheel 3MM - $2.46 x 8 - This part is rather controversial as I used wheels with teeth but should be without. The reason is that wheels without teeth are way more expensive than the ones with teeth. Regardless I found that it works fine. You can exchange this part for GT2 16 3mm wheel without teeth.

36W 3.2A 12V Input AC100V-240V Power Supply - $5.79

Also a bunch of M3 nuts and bolts. Various length.

Also access to 3D printer is needed and also access to CNC is preferred.

All parts for 3D printing are embedded as SketchFab previews. click on the small icon on the left of the preview to go to the page of the part and there is download button.
