Execute Returning to the Machine Origin or Set Datum

This operation differs in the encoder type:

You can set parameter Encoder Type in System Parameters dialog box.

Execute Returning to the Machine Origin

The origin of the machine coordinate system (inherent coordinate system of a machine tool), also called mechanical origin or home, is a fixed point assigned by designing, manufacturing and debugging before the machine tool leaves factory.

It is used to adjust the machine coordinate of the machine tool, so as to ensure the machining position is correct.

Before executing returning to the machine origin, ensure all servo alarms have been removed.

To execute returning to the machine origin, do the following:

  1. In the menu bar, click Machining → Go Home → Go Home Setting. Go Homing Setting dialog box pops up:

    The dialog box pops up after the software starts by default. If you need to cancel the setting, uncheck This dialog pops up automatically when software starts.

  2. Click one of the following:

    • Click All Axes. Z-axis returns to the machine origin firstly, then X-axis and Y-axis return at the same time, and B-axis returns finally.

      Alternatively, click in the machine control area.

    • Click the button for a single axis. The target axis returns to the machine origin.

      To return Z-axis, alternatively, click in the machine control area.

    • If you ensure that the position is the same with the machine coordinate, the machine tool has never been turned off, and E-stop has never occurred, to set the current position as the machine origin, click DirectSet.

Alternatively, click Machining → Go Home and select a method to return to the machine origin.

After executing returning to the machine origin, sign appears in front of each axis in the machine control area.

Set Datum

With an absolute encoder, you can set the current position of the cutting head as the machine origin through setting datum when you use the system at the first time.

Compared to returning to the machine origin with an incremental encoder, it owns the following advantages:

  • No need to set returning orders for all axes in datum setting process.
  • No need to set datum again after restarting the system, and recovering from power interruption and E-stop because the system will automatically read the datum information.

Note: You need to set datum again after replacing battery of the absolute encoder.

To set datum, do the following:

  1. In the menu bar, click Machining → Set Datum.

  2. Set the corresponding axis:

    • A single axis: set datum for a single axis.

    • All: set datum for all axes.

You can select All(Cancel) to cancel datum setting.

After setting datum, sign appears in front of each axis in the machine control area. And after starting the software or releasing E-stop, the system automatically updates the machine coordinate and feedback coordinate according to feedback pulses to make the current machine coordinate match with the actual coordinate.
