Limit Switches
Guide on integrating limit switches to enable automatic homing.
A little fan should be OK, I guess. Where exactly do you want to connect it? The normal 12V plug is blocked by the laser. You would need to add a Y-cable. The other two ports (Motor, Laser) are 12V but driven by the same PWM signal the laser gets. So, the fan would change speed in accordance to the laser power.
How many extra amperage I would pump from the 12v conector without problems? I want to plug a little fan in that connector.
