BLUE-CNC (nema23) Version 1.0
Like many others, I was interested in building a 3D printed cnc, in fact I opted for the TopsCNC (https://www.thingiverse.com/thing:3813481)
But after starting the construction of the TopsCNC I thought that a mechanic based on Nema 17 motors might not be enough, so I decided to adapt the design to some Nema 23 motors, when I realized I had already modified 60% of the design, that's when I launched to completely modify the previous design.
The particularity of the design is a DIY CNC, which mounts Nema 23 motors, being aware that this increases the price of the design, I decided to save part of the budget, installing the entire system with GT2 belts instead of screws.
The electronics part is built by an arduino UNO and a Cnc Shield, with TB6560 drivers.
In my case, use 1000mm aluminum profiles, and the working area I can get is 850mmx850mm.
Actual budget
In 3d filament 1.8 kg would be necessary, in my case it was Petg for the most part, it can also be made in PLA.
Petg € 24 / kg = € 45
PLA € 19 7kg = € 36
In necessary materials we have 330 € with milling machine included
The economic cost would be around 370 €.
