+ | ==== G2 & G3: Controlled Arc Move ==== |
---|

+ | |
---|

+ | Supported by RRF_1.18 and later. |
---|

+ | |
---|

+ | ***Usage*** |
---|

+ | |
---|

+ | * G2 Xnnn Ynnn Znnn Innn Jnnn Ennn Fnnn ''(Clockwise Arc)'' |
---|

+ | * G3 Xnnn Ynnn Znnn Innn Jnnn Ennn Fnnn ''(Counter-Clockwise Arc)'' |
---|

+ | |
---|

+ | ***Parameters*** |
---|

+ | |
---|

+ | * ***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. |
---|

+ | * ***Innn*** The X coordinate of the arc centre ***relative to the current X coordinate*** (optional, ignored if R parameter is present). |
---|

+ | * ***Jnnn*** The Y coordinate of the arc centre ***relative to the current Y coordinate*** (optional, ignored if R parameter is present). |
---|

+ | * ***Ennn*** The amount to extrude between the starting point and ending point.^^1^^ |
---|

+ | * ***Fnnn*** The feedrate per minute of the move between the starting point and ending point (optional, defaults to the current feed rate). |
---|

+ | * ***Rnnn*** The radius of the arc (optional, RRF2.03 and later) |
---|

+ | |
---|

+ | Either the R parameter must be provided, or at least one of I and J must be provided. To draw a complete circle, define the position of the centre using I and/or J and make X and Y the same as the current X and Y coordinates. |
---|

+ | |
---|

+ | ^^1^^Where a tool has more than one extruder drive then Ennn:nnn:nnn etc is supported to allow for the individual movement of each to be controlled directly. This overrides the extruder mix ratio set with M567 |

+ | G2 X90.6 Y13.8 I5 J10 E22.4; (Move in a Clockwise arc from the current point to point (X=90.6,Y=13.8), with a center point at (X=current_X+5, Y=current_Y+10), extruding 22.4mm of material between starting and stopping) |

+ | |
---|

+ | G3 X90.6 Y13.8 I5 J10 E22.4 ;(Move in a Counter-Clockwise arc from the current point to point (X=90.6,Y=13.8), with a center point at (X=current_X+5, Y=current_Y+10), extruding 22.4mm of material between starting and stopping) |

+ | |
---|

+ | G2 X100 Y50 R200 ;(draw a clockwise arc with radius 200 from the current position to X=100 Y=50) |
