Required Reading

From the Thing-O-Matic Assembly Instructions / User Manual:

ReplicatorG and skeinforge configuration (USE THIS TOOL to generate numbers to plug into your software):

  • Makerblock's Profilemaker - Try 0.4mm layer height, 0.5mm thread width, and 2.84mm filament diameter (or measure it yourself with a caliper). Then load up ReplicatorG, open a .STL file, click the "Generate GCode" button, select your configuration profile and click "Edit..." to open skeinforge. Enter the profile maker's settings in skeinforge, click Save All, and return to ReplicatorG to generate gcode and begin printing.
  • Make sure you modify ReplicatorG's start.gcode as shown below.
