Drillingcycles

# Drilling cycles module

Basically the canned drilling cycles is a short G-Code produced by some serious CAM software to make holes.
In addition to adding some features this significantly reduces the number of instructions send through the serial port.

Currently the drilling cycles module implement the first three options in absolute mode `G90` only.
For a complete list/description of G-Code see http://www.tormach.com/g81_g89_background.

#### Note

Incremental mode not implemented (L).

#### Warning

In relative mode `G91`, drilling holes operations are ignored.

# Configuration

Option | Example value | Explanation
--- | --- | ---

drillingcycles.enable | false | Enable drillingcycles module.
drillingcycles.dwell_units | `S` | Dwell units `S` = seconds, `P` = millis.

# G-Code

- `G98` Retract to initial Z
- `G99` Retract to R plane

- `G81` Simple drilling cycle.
- `G82` Drilling cycle with a pause at final depth (Dwell).
- `G83` Peck drilling cycle; incremental drilling with an retract, can be combined with dwell.

- `G80` Mark the end of cycle.
