G90: Use absolute positioning
G92: Use Relative positioning
M220 Snnn: Set speed override percentage to nnn % of defined speed
Set speed to 150 % of normal speed (defined by print file). All axes including extruder will increase the
speed by 50%.
M221 Snnn: Set extrusion override percentage to nnn % of defined speed
Extrude at 150% of normal extrusion (defined by print file). This will not affect other axes.
6.1.4.3.2 Z probing commands
G30: Probe a single point.
This is used, if printing on a small platform, or an even underlayer. Using the ultrasonic distance probe in
the printhead, the printer will move down to the correct distance to the floor and reset the Z-homing
position to this coordinate.
G29: Probe printing area
Using a predefined mesh-grid, the printer will move around the printing area and probe the distances in a
grid.
This grid is used as a transformation matrix to all prints performed after probing, and the printer will
automatically adjust for uneven surfaces in the foundation or on the floor.
WARNING: Default area is 2.5 x 2.5 meter, using 0.5-meter grid size. Before changing these
values, refer to the documentation (see section 6.1.4.3)
6.1.4.4 COBOD Slice
COBOD Slice is a software used to prepare 3D models from various CAD software to print with BOD2
printer. It generates G-code files, which in turn can be read and interpreted by the printer’s web interface
and control board.
Supported import file types:
• .STEP / .STP
• .IGES / IGS
