For me is a laser very usefull - engrave things, cut balsawood, tatto jeans .....
So I update my 3D Printer - Big Size with a Laser.
Here two Videos how it works:
My controller board "Echinus" has only free digital outputs, but for the PWM I need a analog output.
This analog output I generate with an Ardurino Nano and a Potentiometer. With the potentiometer I can adjust the laser power (0 - 255 steps) and the Echinus board swith the PWM on (M3) and off (M5).
Here the wiring schematic:
The Arduino sketch "Poti" can be download at "Files" folder.
For easy removal of the laser I have installed a socket, so it can be switch fast between 3D print and laser.
Update for my 3D Printer - Big Size
I like combo machines, so I upgrade my 3D Printer with a Laser. It is a double head combination. The Laser is easy removable.
