RepRap Kossel printer on loan from Brandon Lu.
Getting Started
An in-person tutorial is possible and required by User:BLu before use of the printer.
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.
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.
Configuration
This is for setup. Under normal circumstances, there is no need to modify these values.
Serial Connection
Serial Port: Auto
Baudrate: 250000
Printer Profiles
Print bed & build volume
Form Factor: Circular
Heated Bed: Checked
Diameter (X/Y>: 200mm
Height (Z): 260mm
Axes
Maximum Feed Rate (X, Y, Z, E): 6000, 6000, 6000, 300

Materials
PLA & ABS: Preferred materials for this printer
TPE / TPC: Flexible filaments will not work reliably with Kossel printer since the printer has a bowden-tube extruder.
History
Head clogs
The printer has been clogged at least five times. Every clog was because of incorrect heat application and has required specialty repairs.
