Laser Warning! Sign and Blinkbox
thingiverse
With the 5.5W LASER hooked up to my MPCNC, I needed a warning sign and a blinking indicator for showing, the machine is active. I followed this example of a NE555 circuit: http://www.led-treiber.de/html/leds_blinker.html It's very easy to solder the 5 components on a small prototypeboard and put it in a printed box (use a 5mm LED and glue it in place). STL included. Then I made two warning signs (DEU and ENG) that you can easily print. Just do a filament change from yellow to black at the appropriate height. I manually put in M600 in the GCODE at layer 13 (may vary with your selected resolution!). So we have at least a bit of laser safety at home! Enjoy
