Co-Processed Servo Motor Test

thingiverse

I processed a servo motor into my print job so that the printer would lay filament down over it. I then used an Arduino to drive the servo motor, enabling it to break build adhesion forces and move itself off the build plate with precision. This test piece is part of a larger project I am currently designing. Please check out my blog here if you want to learn more or are unfamiliar with coprocessing: https://printeraction.wordpress.com/ Instructions: Materials: You will need this servo motor: https://www.sparkfun.com/products/9347 Also required is an Arduino board. To begin, place a small piece of blue tape on top of the servo so that the filament can easily stick to it. When the printer starts to print the flat overhang, pause the print and position the servo motor in its place, with the smaller 180 degree servo horn attached and rotated such that it is touching the ground when the servo is laid down horizontally. Continue printing as normal. The printer will now lay filament down on the surface of the servo motor. Once the print is completed, plug in the Arduino board and run Arduino's "Sweep" example code, but adjust the delay to 700 ms. This adjustment will enable the motor to successfully pry itself off of the build plate!
