How to use it

Calibration (before every job @ metalab)

• There is a calibration sheet inside the witbox.
• Calibration is simple. Just follow the instructions on the menu.
• Configuration -> Level plate

Load / Change Filament if neccessary - Careful not to entangle the filament!!

• To change or unload the filament select the matching option from the menu
• very gently apply some pull to the filament and you will feel that the filament is actually pulled for extraction first and after some seconds it is ejected
• Once the filament is eject apply some more pullign force
• when the filament comes loose pull sharply and remove the filament from the tube completely (also any long debris that might hang off the filament needs to get out)

Save your .gcode to the SD card

• Start cura
• Import .stl
• Save to SD
• You can use folders with your nickname to group your files on an SD card. The Witbox' display will only show the first 19 characters of a filename. So make sure you can distinguish multiple files within that limit so you always print the correct file.
• Done.

Start job from menu

• Select "Print from SD"
• Select your job
• Push dialing wheel- > job starts

Pay used filament

• Calculate used material with your slicer or http://gcode.ws/
• Material costs are 0,10€/gramm
• Deposit appropriate amount in the 3D printing cash box.

Wisdom Tables

These settings have been tested and worked fine. ✔

MATERIAL	Layer height	Speed	Temperature (°C)	Who tried this	Notes
PLA Neon Green	0.1mm	80mm/sec	210C	overflo	Good.
PLA Neon Green	0.2mm	60mm/sec	220C	0x3d	acceptable, 1st layer overhang curls, maybe too hot and slow
PLA WHITE (no name big spool)	0.1mm	80mm/sec	210C	overflo	Looks better at higher temperature
PLA Black bq	0.1mm	80mm/sec	210C	overflo	Good.
PLA Black bq	0.05mm	80mm/sec	210C	overflo	Very fine resolution!, Looks good! Used for TSA keyset
PLA transparent bq	0.1mm	80mm/sec	210C	overflo	Good.
PLA purple noname (3dee.at)	0.1mm	80mm/sec	210C	overflo	Good.
PLA blue noname (3dee.at)	0.2mm	80mm/sec	210C	don	Large rectangular bottom layer was not sticking to the plate with Cura's default Witbox advanced settings. Default first layer thickness = 0.3mm and default first layer speed = 20mm/sec. I changed these to 0.2mm and 80mm/sec respectively and then it worked perfectly.

These settings caused some problems ✘
