See the G-code list below to manually code the Syringe Printhead and customize functionality.
Commands | Description |
G1 Xnnn Ynnn Znnn Ennn Fnnn | When used in combination with the G90 command, which defines absolute coordinates, G1 is the absolute move command. X, Y, Z parameters are the coordinates (in mm) directing where to move. E tells the BIO X to open the valve for extrusion. F is the movement speed of the printhead in mm/min. |
G4 Snnn Pnnn | The G4 command tells the system to dwell. S is the wait time in seconds and P is the wait time in milliseconds. |
G7 Xnnn Ynnn Znnn Ennn Fnnn | When used in combination with the G90 command, which defines absolute coordinates, G7 is the relative move command. X, Y, Z parameters are the coordinates (in mm) directing where to move relative to the current position. E tells the BIO X to open the valve for extrusion. F is the movement speed of the printhead in mm/min. |
G92 Xnnn Ynnn Znnn | G92 sets the current position of the printhead to the specified X, Y and Z coordinates. If no parameters are given, the position is assumed to be 0, 0, 0 (this will also change the Z position). |
Tx | Switch between printhead (x). 0, 1 and 2 designate printheads 1, 2 and 3. |
M771 TX PYY | M771 turns on the heater in printhead Tx at temperature Pyy. yy is between 30 and 65 degrees. |
M2045 Tx E | Set syringe direction to extrude; Tx is the printhead number (Printhead 1 = T0, 2 = T1, 3 = T2). |
M2045 Tx R | Set syringe direction to retract; Tx is the printhead number (Printhead 1 = T0, 2 = T1, 3 = T2). |
M2032 Tx Sy | Set printhead extrusion rate; Tx is the printhead number (Printhead 1 = T0, 2 = T1, 3 = T2) and Y is extrusion rate in nanoliters/sec. |
M2047 Tx E | Fully extrude printhead; Tx is the printhead number (Printhead 1 = T0, 2 = T1, 3 = T2). |
M2047 Tx R | Fully retract printhead; Tx is the printhead number (Printhead 1 = T0, 2 = T1, 3 = T2). |
M2051 Tx Vx | Extrude a certain volume; Vx is the volume in nanoliters and Tx is the printhead number (Printhead 1 = T0, 2 = T1, 3 = T2). |
