Function

Press Dryrun button in the auto mode on the control panel, its indicator lamp is

lit, and CNC is in dryrun status, where the feed rate specified by the program is

ignored, and the coordinate axis moves at the rapidest speed.

The machine doesn’t perform actual cutting in dryrun status. The purpose of

dryrun is to confirm the cutting path and the program.

During the process of actual cutting, this function must be turned off; otherwise,

it may cause danger.

This function cannot work on thread cutting.
