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 G91, drilling holes operations are ignored.

Drilling Cycles Configuration Options

The drilling cycles module provides canned cycles for CNC drilling operations. See the Drilling Cycles page for detailed information on using these features.

Configuration Reference

Option Default Value Description
drillingcycles.enable false Enable drillingcycles module.
drillingcycles.dwell_units 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.
