G-code 学习

G-code 最好的学习资料应该是, https://reprap.org/wiki/G-code

下面是从Cura导出来的Gcode,画了几条线

M104 S20 ; extrude temperature
M105 Get Extruder Temperature
M109 S20 Set Extruder Temperature and Wait

Snnn minimum target temperature waits until the heating

Rnnn maximum target temperature waits until cooling (Sprinter)

Rnnn accurate target temperature waits until heating and cooling (Marlin and MK4duo)

M82 ;absolute extrusion mode
G92 E1

G280 S1
G0 Z20.001

G0 : Rapid Move
G0 Xnnn Ynnn Znnn Ennn Fnnn Snnn
Xnnn The position to move to on the X axis
Ynnn The position to move to on the Y axis
Znnn The position to move to on the Z axis
Ennn The amount to extrude between the starting point and ending point, negtive means retraction
Fnnn The feedrate per minute of the move between the starting point and ending point (if supplied)
Hnnn (RepRapFirmware) Flag to check if an endstop was hit (S1 to check, S0 to ignore, S2 see note, default is S0)1
Snnn Laser cutter/engraver power. In RepRapFirmware, when not in laser mode S in interpreted the same as H.

G1 : Linear Move
Xnnn The position to move to on the X axis
Ynnn The position to move to on the Y axis
Znnn The position to move to on the Z axis
Ennn The amount to extrude between the starting point and ending point, negtive means retraction
Fnnn The feedrate per minute of the move between the starting point and ending point (if supplied)
Hnnn (RepRapFirmware) Flag to check if an endstop was hit (S1 to check, S0 to ignore, S2 see note, default is S0)1
Snnn Laser cutter/engraver power. In RepRapFirmware, when not in laser mode S in interpreted the same as H.
Ref:https://reprap.org/wiki/G-code#M107:_Fan_Off

E is related to the extruded length of the material, and F is the moving speed of the printer head. The flow rate is equal to extruded length divided by traveling time

除此之外,还可能有M205

M205 X20 Y20, 设置了 X Y的travel speed 各为20 mm/s
