examples:

|
-
|
|
pre: The most basic example is to use the command without any arguments, this will default to a stroke based pattern which will be stroked `NOZZLE_CLEAN_STROKES` times.
|
|
code: G12 ; stroke pattern (default)
|
|
-
|
|
pre: To generate a three triangle zig-zag pattern which will be stroked one time use the following command.
|
|
code: G12 P1 S1 T3 ; zig-zag pattern with 3 triangles
|
|
-
|
|
pre: To generate a 10mm radius circle which will be stroked one time use the following command.
|
|
code: G12 P2 S1 R10 ; 10mm circle

Start the nozzle cleaning process. Three types of cleaning patterns are supported: straight strokes, zigzags and circles. This feature requires a dedicated cleaning area on or outside the bed, but within reach of the nozzle. The pattern may be repeated as many times as desired.
