Build Log

Starting Point

• Kit from garagefab.cc to build XY Plotter
  • Mechanical parts:
    • ...
  • Electronic parts:
    • 1 Arduino Diecimilia
    • 2 RepRap Stepper Motor Driver v1.2
    • 2 Stepper Motor
  • Software:
    • Arduino IDE
    • GCode
    • ...
• ATX Power Supply (240v- 250W)
• Tools

Step 1: Building X Axis

• ...

Step 2: Building Y Axis / Frame

• ...

Step 4: Setting up Motors / Transmissions

• ...

Step 5: Wiring-up and Testing the system

• Power Supply from ATX
  • to use ATX as a standalone, you need to connect the green wire to any black wire on the Mother Board connector
• Testing
  • Run the RepRap Driver test to check that everything is ok.

Step 6: Arduino, Softwares, and G-Code

• Arduino 0016
• Arduino Sketch to drive stepper motor (from RepRap project)
  • Download RepRap Firmware (v1.3) and follow instructions
  • Upload sketch onto Arduino
  • Now your Arduino waits for G-Code instructions on its serial port.
• G-Code instruction handler
  • Download and Install ReplicatorG from here
• G-Code generator
  • You can use Cam.py to generate G-Code from images (SVG, JPG, ...)

Performance testing

• Perpendicular trajectories:
  • ...
• Diagonal trajectories:
  • ...

General Feedback

• Sketch-up model:
  • It would be great to use a color code for the different part types in Google Sketchup.
  • It would be good to have a unique label for each part to help feedback (e.g. Letter - Number,like 'D-6', Letter=part-type, Number=instance index)
• Mechanics:
  • We slightly changed the motor/axis coupling on the X axis. We mounted the motor/pulley straight onto belt (see pictures).
  • Sometimes it is difficult to tighten bolts that are under axis.
