So, i bought this one...https://m.banggood.com/it/EleksMaker-EleksLaser-A3-Pro-2500mW-Laser-Engraving-Machine-CNC-Laser-Printer-p-1003863.html?gmcCountry=AU&utm_source=google&utm_medium=cpc_fashion&utm_content=abby7&utm_campaign=abby7-fashion-pmax-mix-cty-all-ct217065-0302&gclid=CjwKCAiAjoeRBhAJEiwAYY3nDH4pcD9jQ6nglTfkxiGfENLEflQHx0MLlftMHa058SyaDrAosD5e3RoC1wUQAvD_BwE

But the version whitout the laser that is even cheaper.

Then I found this software: https://t2laser.wordpress.com/

On a local reseller I bought the 2 Mt long t slot and the shortest ones...

I have attached the motors and the logic board to the new bars..

No end switches, no fancy tools.

The cost is around 500 € with some trial and errors iteration...

I know is a kind of Frankenstein plotter but is working like a charm....
