Slicing Your Model
The general 3D printing workflow starts with a 3D model, exported as an .STL file, which is then put into software (Cura) that slices it into layers and outputs a GCODE file. GCODE is basically a set of instructions/toolpaths for the machines to follow.
Cura is one of many applications (Simplify3D, Slic3r, MatterControl, etc) that slices your STL into layers and converts it to printer-specific GCODE. Cura is a free, open-source software which can be installed and downloaded here: https://ultimaker.com/software/ultimaker-cura
Installing Custom Printer Definitions
- Download 'crafbot.def.json' file here: https://bit.ly/techlab-cura-definitions
- Add our custom Cura definition file 'crafbot.def.json' to Cura's 'definitions' folder:
- Windows: C:\Program Files\Ultimaker Cura <version #>\share\cura\resources\definitions
- Mac: Run Cura > Click "Help" on top left > Click “Show Configuration Folder” > Browse to "definitions" > copy in definition file and close Cura
- Linux: Copy [printername].def.json files into ~/.local/share/cura/4.9.1/definitions (In Terminal, cp -a [location saved]/definitions/. ~/.local/share/cura/4.9.1/definitions), restart AppImage
- Run Cura
Adding Printers to Cura
- Go to Settings > Printer > Add a non-networked printer...
- Scroll down to CraftUnique > CraftBot Plus
- Add Printer
Extruder Settings
- Go to Settings > Printer > Manage Printers
- Select CraftBot Plus > Machine Settings
- Go to Extruder tab on the right hand side
- Under Nozzle Settings > Compatible material diameter > Set to 1.75mm > Close
Using Cura
- Load your STL or OBJ file
- Manipulate your model as necessary (rotate, scale, etc)
- NOTE: Our profiles have been preloaded with optimized settings designed to work well for most prints. Please do not alter them until you familiarize yourself with how our printers operate.
- Recommended Default Settings:
- Layer Height: 0.2mm
- Wall Thickness: 0.8 mm
- Infill Percentage: 20%
- Print Temperature: 215° C
- Bed Temperature: 60° C
- Print Speed: 45 mm/s
- Click 'Prepare' (bottom right corner)
- 'Save to File/Save to Removable Drive' (save as GCODE)
