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.

Materials: PLA, ABS

RepRap Kossel printer previously 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

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.

M106 S51

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)

  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.

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

These settings may or may not appear depending on your slicing software. Attempt to apply these settings.

Print bed & build volume

Form Factor: Circular

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

Gallery

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.

OfferUp and Selling

The printer was sold on offerup for $100.

Lending Terms

Kossel Delta is currently on loan from User:BLu, hereinafter referred to as "owner."

Any member or visitor of MAG Laboratory, heinafter referred to as "user," may use the printer given the included configurations and with modifications of these printer configurations. Users excluding qualified 3d printer maintainers as defined by the owner shall not attempt alterations or repairs on the printer. Users excluding qualified 3d printer maintainers as defined by the owner shall not attempt to change filament on the printer. (Soon to change)
