General Advice and Precautions
Precautions
Cooling
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.

Directions
The Octoprint server can be reached at http://192.168.254.95 Login credentials can be found on the printer.
Slicing with Octoprint (easiest)
- Click "Upload" button
- Select the file you want to upload
- 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.
- Click the "Slice" button.
- In the "files" section click the .gco file you just created.
- 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.
- If you are satisfied with the slicer output, click "Print" in the "State" section of the page.
- The printer will initiate printing.

Start G-code
This code runs after the printbed and extruder are heated. Since the extruder heats relatively quickly, the thermal mass of the heatsink is enough to stave off malfunctions.

Head clogs
This printer requires specialty configuration to keep the fan spinning while the extruder is heated. Do not print without the fan running. The printer has been clogged at least five times. Every clog was because of incorrect heat application and has required specialty repairs.
