3D printed for plotter or laser engraver.

thingiverse

This part was crafted using software MOI 3.0. You can use it to build mini CNC machines, such as drilling machines, plotters, or laser engravers. I built a laser engraver with this design. The working area is 30 x 30 cm for plotter XY or laser engraver units. To assemble the machine, you'll need: 5 aluminium T-slot profiles (20x20 mm), each 400 mm long. 3 Nema 17 - 2 motors for axis Y and one for axis X. 2 rods with a diameter of 8 mm, each 440 mm long, for the Y-axis. 2 rods with a diameter of 8 mm, each 430 mm long, for the X-axis. 8 LM8UU bearings. 1 clone Arduino UNO control board. 3 A4988 stepper drivers. For software, I used GBRL 1.1f. You can find more information on configuration at https://github.com/gnea/grbl/wiki/Grbl-v1.1-Configuration. When building a laser engraver, remember: safety first! Always exercise caution when working with lasers. The laser diode is extremely hazardous to your eyes! Wear goggles that are adequate for the laser's wavelength at all times.
