RepRap Kossel printer on loan from Brandon Lu.

General Advice and Precautions

Do not use without first getting permission from Brandon. Components such as the extruder are finicky and may be seriously damaged without the proper settings.



Do not let the extruder heat up without a powered fan. The recommended fan setting is always above 20%. The printer accepts fan commands in pulse-width-modulated counts ranging from 0 to 255. Always set the printer to a count of 51 or more counts when the extruder is heated up or it is expected to heat up.

Bed Leveling

Please consult Brandon before attempting to relevel the bed. Removing the glass with the parts before breaking the parts loose helps to reduce the need to frequently relevel the bed.


The Octoprint server can be reached at Login credentials can be found on the printer.

Slicing with Octoprint (easiest)

  1. Click "Upload" button
  2. Select the file you want to upload
  3. In the "Slicing *file you selected*" prompt, select slicing profile (Kossel, Kossel Support 1, Kossel Support 2). Support 1 generates support material only where the part overhangs above the bed while support 2 also generates support material where the part overhangs above itself.
  4. Click the "Slice" button.
  5. In the "files" section click the .gco file you just created.
  6. Click "GCode Viewer" tab on right half of the screen to view the slicer output. Layers can be viewed by dragging the sliders adjacent to the simulated platform area or by clicking the buttons.
  7. If you are satisfied with the slicer output, click "Print" in the "State" section of the page.
  8. The printer will initiate printing.


This is for setup. Under normal circumstances, there is no need to modify these values.
