Sets units to millimeters


G90

Use absolute coordinates

G91

Incremental positioning
G92

M83

Set extruder to relative positioning

M84

Movement Commands


G0

Rapid linear move

G1

Linear move

G2

Move clockwise arc

G3

Move counter-clockwise arc

G4 PX

Pause for X milliseconds (dwell)



X

Move in X-direction

Y

Move in Y-direction

Z

Move in Z direction

F

Set speed for movement (usually in mm/min)
ELength of filament to consume

I

X-offset for arcs

J

Y-offset for arcs

K

Z-offset for arcs

R

Radius of circle for arcs, e.g., G02 X+2.00 Y+0.00 R2.00




The special M codes for the INKREDIBLE(+) 3D Bioprinter


M712 to M732 are used to set the offset between the printheads. Printhead 1 and 2 are the cartridge holders and printhead 3 is the LED.

Note: This will not place the chosen printhead in the active position


M712

Set offset from 1 to 2

M713

Set offset from 1 to 3

M721

Set offset from 2 to 1

M723

Set offset from 2 to 3

M731

Set offset from 3 to 1

M732

Set offset from 3 to 2



M750

Homes the printheads


This needs to be done before any automatic switching of the printheads can occur. After this command, Printhead 1 will be in the active position.


M751

Places Printhead 1 in the active position

M752

Places Printhead 2 in the active position

M753

Retracts both printheads, making way for the LED to be used



T1

Change extruder



M760

Opens the valve for Printhead 1

M761

Closes the valve for Printhead 1

M762

Opens the valve for Printhead 2
