// Clean Nozzle Feature -- EXPERIMENTAL
//
// When enabled allows the user to send G12 to start the nozzle cleaning
// process, the G-Code accepts two parameters:
// "P" for pattern selection
// "S" for defining the number of strokes/repetitions
//
// Available list of patterns:
// P0: This is the default pattern, this process requires a sponge type
// material at a fixed bed location, the cleaning process is based on
// "strokes" i.e. back-and-forth movements between the starting and end
// points.
//
// P1: This starts a zig-zag pattern between (Xs, Ys) and (Xe, Ye), "S"
// defines the number of zig-zag triangles to be done. Each "side"
// cannot be less than 5mm. As an example "G12 P1 S3" will execute:
//
// /| /| /| (Xe, Ye)
// / | / | / |
// / | / | / |
// (Xs, Ys) / |/ |/ |
//
//
// Caveats: End point Z should use the same value as Start point Z.
//
// Attention: This is an EXPERIMENTAL feature, in the future the G-code arguments
// may change to add new functionality like different wipe patterns.
