Mini-CNC v0.14

thingiverse

Check out this updated version of my tiny CNC drawing robot at http://www.thingiverse.com/thing:200895. Hold off on printing for a few days as I'm working on improvements. For more info, visit my blog at plotterbot.com and the Robot Hacks (https://plus.google.com/communities/114867980170611537174) page. This is a beta version with room for improvement, but it's cheap to build at an estimated $50 including an Arduino Uno. Keep an eye on my blog for updates and improvements, including a better Y stage for pen holding and drawing capabilities. The current model runs a basic servo "sweep" sketch. Assembly instructions are as follows: 1) Place the large base (Xrack014.stl) on a flat surface, 2) Insert a servo motor into the X stage motor mount (Xmotormount014.stl), 3) Put the X pinion onto the X stage servo (Xgear014.stl), 4) Put the X stage motor mount with pinion into the base, 5) Put a servo motor into the Y stage motor mount (Ymotormount014.stl), 6) Put the Y pinion onto the Y stage servo (Ygear014.stl), 7) Put the Y stage motor mount with pinion onto the X stage, and 8) Place the Y axis rack between the Y pinion and the X stage motor mount.
