BinaryCNC

BinaryCNC - only the laser is bought, the rest is in the workshop and in the office equipment dump!
Cylindrical shafts, LM8UU bearings and stepper motors are extracted from old photocopiers.
In the workshop we find the Arduino CNC shiels control board (I have two ;-) and threaded pins.
You need to print one part of the head, two axes Y and 4 - X, hence the name - Binary!
Yes, giving a second life to the components of old equipment is far from a new idea.
I just developed the most simplified design.
But even if you buy everything, with a 30W laser it will be twice as cheap as the system from AliExpress.
Many people like to build something during the New Year holidays, so I did everything early so that you have time to buy the components.
Merry Christmas!

For a device with a working field of 40x40 centimeters, you will need shafts of the following sizes:
4x50cm cylindrical guides
2x52cm M10 threaded studs
2x50cm M10 threaded studs

In addition, you need:
3x NEMA-17 34mm high (no more)
3x GT2 20T sprockets
4x GT2 20T bearings
3 meters of timing belt GT2 6mm
Arduino Nano(Uno) and CNC Shield for it or RAMPS+Arduino Mega
Laser module - power according to your need
Power supply unit 12 Volt, 30w + laser power.

Fastener:
16 M10 nuts
12 M3 screws 10mm long
6 M3 screws 20mm long with nuts
5 M4 screws 20mm long with nuts
12 screeds with a width of 2.5 mm

WARNING! Before installing the X-axis belts (white), make sure that the stepper motors are counter-rotating!
