Sharpie in action


First drawing using the penlift mechanism to raise and lower a sharpie at the right time (in sync with position on XY table). Made using a solenoid salvaged from an old iomega zip drive.


Solenoid pen actuator salvaged from iomega zip drive


Made a working pen lift mechanism for the XY table. Now drawings can be made with a sharpie or pen, or maybe even an Xacto knife can be used with it to cut out intricate designs.

Now we can verify designs before hooking it up to the new (old) laser. The pen up/down gcode commands will be used to switch the laser shutter Off/On.
