Description of Issue

The machine can report a Check Cut Motor message when the sensors are not reading the expected cut motor RPM.  This cut motor message can be disregarded if the user desires.  The motor will run without the sensor feedback but may run fast.

Possible Causes

Causes include: a cut motor that is not spinning (various reasons), a bad cut motor sensor, a faulty cut motor sensor magnet, or a faulty X termination board.

Troubleshooting Steps

  1. Check to see that the cut motor is spinning when it should be spinning.  If the cut motor is not spinning see the section titled “Cut Motor Not Spinning”.
  2. Check to see that the cut motor sensor is recording the shaft as it spins.  To check the status of the cut motor sensor, go to the CarveWright Main Menu->Configuration->Sensor Check menu.  Use the arrow keys to find the item titled “Cut Sensor” on the bottom line of the display.  Spin the spindle as fast as possible by hand and see if the count on the display changes.  If the count is not changing the magnet and/or the cut sensor is bad.
  3. If the cut motor RPMs are fluctuating during the project (readily heard), check the leads on the large brown capacitor on the X termination board for breakage.  Replace the X termination board if necessary.
  4. If none of the above steps solves the issue consult a senior engineer.
