Drilling Cycles Module

Drilling Cycles

The canned drilling cycles module 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 sent through the serial port.

Currently, the drilling cycles module implements the first three options in absolute mode G90 only.

For a complete list/description of G-Code, see Tormach’s G81-G89 Background.

Incremental mode not implemented (L). In relative mode {::nomarkdown}G91{:/nomarkdown}, drilling holes operations are ignored.

Configuration

Option Example Value Explanation
Option Default Value Description
false Enable drillingcycles module.
`S` Dwell units S = seconds, P = millis.

G-Code

Retract Modes

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

Drilling Cycles

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

End Cycle

  • G80 - Mark the end of cycle.
