DIY CNC Laser/Mill/3D Printer

Last weekend I've successfully completed first tests with the first prototype of my self designed CNC.
Also I could test the 2W laser with the self-made laser control.

After long time of designing, brooding about the functionality, it looks like it's working :)

CNC

The first draft was made in January 2011, but during lot of work and other projects (Like the laser project) I couldn't build it up earlier.

Actually there are only two axes, also the material of some parts are out of wood and not that stable, but for the laser it's enough...

Laser

The laser is a 2W Diode Laser with 445nm. The Controller is made out of an Arduino.
Features:

• Control of laser power TTL (0-100%) over Poti
• Emergency Button & Key Switch -> Interlock
• Display with Actual Power, actual/min/max Temperature of driver and laser
• Button to reset min/max temps
• Automatic fan control (PWM) for driver fan and laser fan.
• Button for Unlocking (Arming) with buzzer
• Overheating Protection -> Interlock, Beeping, Red LED
• Interface for Spindle Control
• Two LEDs -> Yellow - Armed / Red - Overheat

3D Printer

I've already designed a "Tool" for 3D printing which melts pellets, so you don't need to buy the filament. The Controller for this Tools is about 70% done but for the mechanical parts a CNC is needed... So first I'm going to finish the CNC.
