We have several 3D printers: a Lulzbot Mini, TAZ6, and a Prusa i3. All are connected to a 3DPrinterOS server, which allows for remote access. [toc]
When printing on the Lulzbot Mini, the recommended workflow is as follows:
- Start Cura
- File > Open Profile and select the profile most similar to what you'd like to print. The profiles can be found on the Lulzbot website.
- Configure the print as needed
- Save gcode
- Navigate to http://octoprint.local, upload the g-code, and print
- Visit http://octoprint.local
- Upload .stl file to Octoprint
- In the dialog box select the pre-generated method that matches your filament type/structural needs
- Octoprint will automatically slice and load the g-code for that model. Depending on your settings the model may automatically begin printing or remain in the loading phase.
The Lulzbot uses 2.85 or 3mm filament. Loading Filament
- Select the filament you would like to load
- In Octoprint, manually set the nozzle temperature to the melting point of the filament currently loaded in the printer.
- Undo the latch in the extruder, and remove the filament in the printer.
- To load new filament, cut off a small amount of filament at about a 45 degree angle to assist in loading
- Guide the filament into the extruder until it extrudes out the hot nozzle. Re-latch the extruder bearing.
For the Prusa i3 there are many similarities to the Lulzbot mini. A few distinctions are listed:
- 1.75mm nozzle
- http://octoprint.local:5001 for web control
- Presently, a layer of blue painters tape is reccomended in order to allow for the best bed adhesion.
- If the bed of either printer appears dirty, the best practice to clean it is with the Isopropyl alcohol located next to the print tower. Use only a clean paper towel or scotch pad when necessary
- To remove a stuck print, best practice is to heat the bed to about 50C to loosen the printed part, then the part should come off with relative ease.
