Dimension Drawing (Unit: mm)

The dimension drawing of NK105G3 handheld box is as follows:

Main Software Interface

The main software interface differs in axes. General NK105 with four axes and that with three axes are the same, except the axis number, so their main interfaces are similar. Therefore, this manual does not introduce the main interface of general NK105 with three axes.

General NK105 with Four Axes

When general NK105 with four axes starts, the system automatically enters the machining interface in the manual mode (ie. Jog or Step mode).

The main interface is as follows:

Activated axes

The figures refer to the selected WCS. Specifically, 1 / 2/ 3/ 4/ 5/ 6 respectively refers to G54/ G55/ G56/ G57/ G58/ G59.
Coordinates
Operation status
- Idle: Default status.
- Running
- Pause
- Stop
- Locked: NK105 is locked when the soft limit is triggered.
Spindle status
- Enabled
- Disabled
Speed mode
- High-speed jog
- Slow jog mode
Motion mode
- Jog: Finely adjust the machine coordinate.
- Step: Coarsely adjust the machine coordinate.

General NK105 with Double Z Axes

The main interface is as follows:

Activated axes
Coordinates
Operation status
- Idle: Default status.
- Running
- Pause
- Stop
- Locked: NK105 is locked when the soft limit is triggered.
Spindle status and coordinate system
- Spindle status
  - Enabled
  - Disabled
- Coordinate system
  
  When the coordinate system turns to show the MCS, this area shows G53; when it turns to the WCS, this area shows G54 (default one) / G55 / G56 / G57 / G58 / G59.
Speed mode
- High-speed jog
- Slow jog mode
