Unimplemented
The following features have been documented and intended, but not yet implemented.
G2.3 3-Space CW Arc
A G2.3 move specifies a clockwise arc (or complete circle(s) from the current position to position (X,Y,Z)curr following a circular arc about the center point (Xcurr+I, Ycurr+J, Zcurr+K). Unlike G2, G2.1 and G2.2, G2.3 is not bound to the X/Y plane. The number of full 360 arcs can be specified as well as the pitch (centerline between arcs). Usage
G2.3 Xn Yn Zn An Bn In Jn Kn Un Vn Wn Dn Pn En Sn Fn
Note: If we are in G16 mode, Un, Vn, Wn define the vector normal to the work plane. If we are in G17 (X/Y plane) or G18 (X/Z plane) or G19 (Y/Z plane) mode, these are ignored.
Parameters
Xn is the new X position to end at Yn is the new Y position to end at Zn is the new Z position to end at An is the new A position to end at (4th axis) Bn is the new B position to end at (5th axis) In is the relative distance from the current X position to the center position about which to arc (default 0) Jn is the relative distance from the current Y position to the center position about which to arc (default 0) Kn is the relative distance from the current Z position to the center position about which to arc (default 0) Note: In, Jn, and Kn all default to 0, but at least one of them must be explicitly declared with a non-zero value. Un is the X component of a vector normal to the working plane (default 0) Vn is the Y component of a vector normal to the working plane (default 0) Wn is the Z component of a vector normal to the working plane (default 0) Dn is the overall displacement normal to the working plane for this element Pn is the pitch (how close the laps are normal to the working plane) in mm (default 0; one path, no incremental displacement) En indicates a working or printing move Sn dictates how many segments are used to create the arc (or circle); 0.33333 mm is the default value S values less than 3.0 dictate the length in mm of each segment for this element S values of 3.0 or more dictate how many total segments comprise this element - only allowed on complete circles of 360° Fn is the Feed rate (travel speed) at which to execute this move.
Any values not stipulated remain unchanged. We will print this element with our native Hyrel flow calculations (based on nozzle diameter, layer thickness, and feed rate) even if your gcode has enabled the use of E values with M229 E1 D1.
G3.3 3-Space CCW Arc
Please refer to G2.3, above, for details. All options are identical, with the exception of direction (CCW).
