creates a cubic B-spline in the XY plane with the X and Y axes only. P and Q parameters are required. I and J are required for the first
command in a series. For subsequent
commands, either both I and J must be specified, or neither. If I and J are unspecified, the starting direction of the cubic will automatically match the ending direction of the previous cubic (as if I and J are the negation of the previous P and Q).
to understand how Bézier control points work.
It is an error if an axis other than X or Y is specified.
G5 [E<pos>] [F<rate>] I<pos> J<pos> P<pos> Q<pos> X<pos> Y<pos>
The length of filament to feed into the extruder between the start and end point
The maximum feedrate of the move between the start and end point (in current units per second). This value applies to all subsequent moves.
X incremental offset from start point to first control point
Y incremental offset from start point to first control point
X incremental offset from end point to second control point
Y incremental offset from end point to second control point
A coordinate on the X axis
A coordinate on the Y axis
For example, to program a curvy “N” shape:
G0 X0 Y0
G5 I0 J3 P0 Q-3 X1 Y1
A second curvy “N” that attaches smoothly to this one can now be made without specifying I and J:
G5 P0 Q-3 X2 Y2
