====== CNC Sheet Router - Operational Guide ======

===== SOP =====

==== Before Turning On the CNC ====

  - Make sure the air compressor is on.
  - Make sure the air dryer is on.
  - Open the air for the CNC.
  - Remove any objects in the path of the gantry.

==== Turning On the Machine ====

  - Tap your card on the interlock.
  - Providing you have access, press the green button on the front panel of the machine. \\ **Note:** If the machine doesn't go on, double check the off button is not depressed.

==== Setting up the controller side of things ====

  - Home the machine
  - Setup your tools
  - Load the tools on the tool gang
  - Measure the tool height offsets
  - Transfer your files into the controller
  - Setup your work offsets
  - Setup your rigs, fixtures and stock accordingly

==== Right before cutting ====

  - Turn he vacuum clamp on if you're using it.
  - Turn on the dust collection
  

===== Troubleshooting =====

==== Initial Checks ====

Once the controller boots up, you might be greeted with some alerts. Once you check each alert, click **Reset** to clear the alarms.

==== Most Common Alerts on Startup ====

=== ALM - [PLC ALARM] LACK OF AIR PRESSURE ===

The machine is not getting enough pressure. Double check:

  - The compressor is on and the system is pressurized (0.73 MPa).
  - The valve is open. (NOTE: Take photo)

=== WARN - [PLC WARNING] AFTER BOOTING, THE 4TH AXIS NEVER RETURN HOME (Same for X, Y and Z) ===

You will always receive this warning. The machine needs to run the homing sequence to start operating normally.

=== ALM - [PLC ALARM] EMERGENCY STOP ===

An E-Stop is depressed. You have one on the controller and one on each side of the gantry. Check all of them are released.

===== How to =====

==== Running the Homing Sequence ====

  - Before running the sequence, double check that nothing is in the way of the gantry and the table is clear.
  - On the bottom bar:
    - Click on **ZRN**.
    - Click on **CYCLE START**.
  - Once the sequence is finished, you should see:
    - X- lit in yellow
    - Y- lit in yellow
    - Z+ lit in yellow
    - 4+ lit in yellow

==== Measuring Tools ====

  - Navigate to the top menu.
  - Click **Setup**.
  - Click **ATM**.
  - Set parameter **T.NO** to the number of the tool you want to measure.
  - Double check that the **REF. X POS** parameter is set correctly:
    - Normal Tool:
      * x = 67
      * y = 2670
    - Skimming Tool:
      * x = 107
      * y = 2670
  - Double check that the **REF. Y POS** parameter is set correctly: ''2670''
  - Click **ATM.ST**.
  - Repeat for all tools as needed.

===== Importing a NC File =====

  - Travel to the top menu.
  - Click **Monitor**.
  - Click **USB DISK IMP**.
    - On the right panel, select the files you want to transfer.
    - Click **TRFR**.
  - Travel to the top menu.
  - Click **Monitor**.
  - Click **File**.
  - Select the NC file you want to cut.
  - Click **GRAPH** to preview the program.

==== Setting Up Work Offsets ====

=== Setup G54 Using Known Coordinates ===

  - Travel to the top menu.
  - Click **Setup**.
  - Set your G54 offsets accordingly. \\ **Note:** Pay attention to your base coordinates.

=== Setup G54 by Picking Coordinates ===

  - Move the end of the current tool to the point of interest.
  - Travel to the top menu
  - Click **SETUP**
  - On the Setup page, click **TEACH IN**.
  - Select the work offset you would like to set.
  - Depending on the coordinate you want to set, press the button accordingly (e.g. SET ALL, SET X, SET Y, SET Z, SET A).
  - NOTE: Keep in mind that the Z coordinate shouldn't be measured using this method. Please read **Picking Coordinates for the Z Axis**.

=== Picking Coordinates for the Z Axis ===

  - Move the end of the current tool to the point of interest.
  - Travel to the top menu.
  - Click **Setup**.
  - Click **ATM**.
  - Set the parameter **T.NO** to the current tool in the spindle.
  - Click **Z SET**.

Explanation: In most cases postprocessors will output programs with tool height compensation. If you measure a point of interest using Teach In Z, the tool height offset of the current tool will **not** be taken into account. This can lead to issues and potentially cause damage. This is why u need to measure Z coordinate using the above instructions.
