Execute Returning to the Machine Origin / Set the Datum

This operation can help the machine coordinate system of NcStudio V10 Waterjet Cutting Control System match with that of the machine tool for a preciser machining.

Before returning to the machine origin, ensure all alarms have been cleared.

According to the encoder type, it can be divided into the following:

• For an absolute encoder, set the datum.
• For an incremental encoder, execute returning to the machine origin.

Set the Datum

This operation is used to directly set the zero for the absolute encoder.

Except the following conditions, this operation is unnecessary because the system will automatically read datum of each axis:

• It is the first time to install the software.

• The software is updated.

• The absolute encoder runs out of battery.

• The datum file has been damaged.

Before setting the datum, ensure the following:

• Hardwares have been connected well.

• The axis direction is correct.

For double Y axes configuration, before setting Y-axis datum, to adjust parallelism of double Y axes, make the fine adjustment for Y1-axis and Y2-axis in POS DIAG window and make a trial cutting.

Taking X-axis as an example, to set the datum, do the following:

1. To enter POS DIAG window, click POS DIAG.

2. To activate datum setting buttons, click RefSet or press F3, and input the manufacturer password.

3. To open Table Travel Set dialog box, click X Datum → Yes.

4. To set the upper limit of the workbench travel, move X-axis in the positive direction to a reasonable position, and click Upper Limit.

5. To set the lower limit of the workbench travel, move X-axis in the negative direction to a reasonable position, and click Lower Limit.

6. Click OK.

The system starts to read datum data.

Repeat the steps above to set datums for other axes, and restart the software to validate settings.

To directly use the set datums after updating the software, export the set datums as an INI file by clicking Export Datum. After updating the software, insert the USB flash disk with the INI file and click Import Datum.

Execute Returning to the Machine Origin

With an incremental encoder, every time you restart the software, you need to return to the machine origin before machining. But if no abnormal phenomenon occurs during this machining, you do not need to execute this operation before the next machining.

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

1. To open BKRef dialog box, do one of the following:

   • Click Operate → Back to Reference Point.
   • In Manual mode, click REFER in POS window.

   

   You can check This dialog box appears automatically when the software starts at lower left corner. BKRef dialog box will automatically pop up when the software starts next time.

2. Do one of the following:

   • To return Z-axis to the machine origin first and return the other axes, click All Axes.

   • If you ensure the following, click Direct Set to directly set the current position as the machine origin:

     • The current position is the same with the machine coordinate.
     • The machine has never been turned off.
     • E-stop has never occurred.

   • To return a single axis to the machine origin, click X-axis / Y-axis / Z-axis / A-axis / B-axis / C-axis.

     For safety, it is recommended to return Z-axis first.

After executing returning to the machine origin, the sign appears after the corresponding axis in coordinate display area.
