Universal CNC machine

Post by edi_the_eagle » Sat May 09, 2020 9:06 pm

I'm a oldscool precision mechanic from Switzerland and I'm building a small universal CNC machine.
The aim of the project is milling, engraving aluminiun, brass and plastic, 3d printing and also laser engraving (plastic ,wood, leather and so on).
My hardware:
Cube made of aluminium profile 30x30 mm, size over all 400x400x400 mm.
Travel X=275 mm, Y=150 mm, Z=100 mm

The ball screw for the Y-axis came over the Silk Road but I'm not happy with it :roll:
The other parts come from old machines that I bought cheaply on an online platform.
Milling table 300x200 mm in aluminium with T-slots
The milling spindle is on work.
NEMA 17 Stepper motors for all axis
Raspberry Pi 3 with CNC-HAT
Arduino Nano for use with klipper (https://www.klipper3d.org/Overview.html) to manage the hotend and the heatbed.
I'm not sure yet that it works like that, there's still a lot to do.
Maybe someone here has already made experiences with klipper and the CNC-HAT :?:
The laser module ist a 5 Watt 450 Nm blue laser
The controller will be mounted in an old PC housing
11 inch LCD display
Software:
bCNC for milling and engraving
Octoprint for 3d printing
to do:
Mounting the stepper motors, align the whole construction, wiring up electronics, front and back panel of the controller and testing
