The latest update of myCNC software (v1.88.4586) brings improvements to the drilling cycles within myCNC.

Added the following options:

• G98/G99 for lift to initial height/height R
• G83 for peck drilling cycle
• G81 for single drilling cycle
• G73 for drilling cycle with lift to clearance height
• Drilling lift speed L - useful to avoid drill jams that would occur when lifting at standard jog speed

A sample drilling cycle that is used in the myCNC software is shown below:
