    Alright, I just rejointed the board, Placed tape on the board tracking sensor edge of the project piece, cleaned the entire Carvewright, greased the all thread pieces and four guide post.
    Now I am having issues that the clutch on the crank handle is no longer working, and when running a simple sensor check with the head up the front compression roller shows to be released but back is showing compressed. I believe that is what is causing the machine to think that the board tracking sensor is failing? Gimme some advise here please.. Ya'll have been great and so far these forums have proved to be my favorite part of the carvewright (I really like the CW when it works)

    Lift the top up as far as it will go, be careful not to jam top up.Take hold of the rear roller and push up and down,as you are doing this try and blow the end of the roller clean,this being on the computer side. Good luck. Capt Barry

    The compression roller not showing released is normally caused by sawdust getting into the switch. As unitedcases said, loosen it up a bit and blow it out. The switch is on the keypad side of the machine, at the end of the roller.
    As far as the crank not working, did you crank it all the way up when you where cleaning out the machine? If so, there is a hole in the threaded rod of the right side of the machine that you can get a allen wrench or small screw driver into to turn it. Start it down that way until the crank starts working again.

    No I am referring to the clutch that releases when you have applied enough downward force just before you apply the red safety handle...
    The back roller issue was a result of sawdust I have 109Hrs on my machine and this is the first time it has done that. Thank you for your help!

    Unhappy

    Alright I just changed the qc chuck and took every piece of advise that has been given to date! NOW the machine keeps saying clear board sensor. I have cleaned the edge sensor with air, vaccuum, and alcohol, yet still clear board sensor edge sensor error??????????????

    What next????

    Default Clear Board Sensor

    Please Clear Board Sensor Message
    Description of Issue
    This error appears when the sensor used to find the edges of the workpiece is not seeing reading
    within its operational limits. The sensor system consists of an infrared LED and an infrared
    detector. The board sensor works by reflecting infrared light off of the board and reading the
    intensity of the reflection. When the board is underneath the sensor, the reflected intensity is
    high and when the sensor is off the edge of the board, the intensity is low. The LED and detector
    are mounted behind a clear window in a plastic case at the bottom of the horizontal moving YTruck.
    Possible Causes
    There are several reasons why the machine will prompt the user to “Clear Board Sensor”
    including:
    1. There is dust obscuring the sensor lens.
    2. There is dust piled in the machine to the right of the board that looks like a continuation of
    the board to the sensor.
    3. There are existing features on the workpiece, like holes or other carved features, which
    prevent the sensor from tracking the top surface.
    4. The material is too transparent or reflective.
    5. The board is positioned incorrectly in the machine; usually the board is installed on top of
    the squaring plate instead of up against it. It will also give this error if the board is placed
    in the middle of the machine and not slid up against the strongback.
    6. The environmental temperature is below 40 degrees Fahrenheit.
    Troubleshooting Steps
    The following steps only touch on the most likely causes of this issue. For an in-depth
    troubleshooting procedure please consult the detailed trouble shooting document titled “Please
    Clear Board Sensor”
    1. Clean the Board Sensor. The most common reason for this issue to occur is that the sensor
    is obscured by dust. To clean, simply blow low-pressure compressed air (<80 psi) onto the
    sensor window or wipe with a clean cloth. It is recommended that this sensor be cleaned
    after every project. If using pressurized canned air make sure to keep the can vertical. If
    the can is tipped upside down it will eject a stream of freezing liquid instead of air. This
    will usually damage the sensor.
    2. Verify that the temperature is above 40
    oF.
    3. Verify that the board is pushed up against the squaring plate and not riding on top of it.
    4. Check to see that there is no dust piled on the squaring plate that may trick the sensor.
    5. Verify that there are no existing features on the workpiece, like holes or other carved
    features, which trick the sensor into thinking that it has found the edge and preventing it
    from seeing the entire top surface of the board. Use masking tape to hide these features
    from the sensor.
    6. Verify that the material is not too transparent or reflective. Since the sensor works by
    using reflected light to determine the board edge, any material that is very light in color or
    LHR Technologies, Inc. CarveWright™ Troubleshooting Guide (Rev 1.07) 05/10/11 13
    very dark in color cause it to get a reading that is out of its normal limits. This can be fixed
    by placing a piece of masking tape on the surface of the workpiece along the line that the
    sensor traces while measuring. This generally requires placing tape across the width and
    length of the workpiece.
    7. If the board sensor error cannot be resolved by doing the above checks you will need to
    check the sensor readings directly to see if it is working properly. To check the status of
    the board edge sensor, go to the CarveWright Main Menu->Configuration->Sensor Check
    menu. Use the arrow keys to find the item titled “Board Sensor” on the bottom line of the
    display. Do the following checks:
    a. Load a pine or similar colored board, lower the head, and check the reading
    displayed on the LCD when the sensor is over the board. Anything reading over 90
    is acceptable. Anything under 90 requires a new sensor.
    b. Check the reading displayed on the LCD when the sensor is not over a board by
    moving the cutting head all the way to the left. The correct reading should be less
    than 10 and ideally 0.
    c. Raise the head, so that a small board can be easily place underneath the Board
    Sensor. Move it up and down so as to cause the Board Sensor reading to go greater
    than 50. Quickly remove it from under the sensor. The reading should drop
    immediately to less than 10 and ideally 0. If it does not drop immediately the
    sensor is faulty and needs to be replaced.
    8. If none of the above steps solves the issue consult CarveWright and the detailed trouble

    shooting document titled “Please Clear Board Sensor”.

    Fine dust will build up in the lens where the board sensor is under the Z-truck. Every now and again you have to remove it and clean it out. If you have to remove the lens you can find a piece of flat clear plastic, i.e. like what toys are wrapped, that type of packaging, and cut a new piece. I usually save a old battery packs and use the flat plastic off the backs of those. After you clean just put a small amount of superglue on the edge to reseat and readhere it and screw it back on and you should be good to go. You also have to look and what kind of wood you are using. If you are using dark wood I believe, (and I could have it backwards), it will give you that error as well.

    I am jumping into this at the end but wanted to add a few things.....

    Yes, the Rollers have a direct effect on the Board Sensor. Depending on the Direction of board movement the board letting the roller release is a computer trigger for the board sensor to start looking for the board edge. Sort of a Electronic "Get Ready" to LOOK.... So if a roller never releases then the board sensor will not start to look.

    The roller not releasing properly can be a loose screw on the under side of the machine that goes into the 4 smooth rails. This is for a board measuring problem where the distance is about 1/4 inch of movement. I have had this on my machine.

    Now for a roller not releasing when the head is cranked away from the board can be packed sawdust in and on the flat metal plate with 2 screws into it. In my picture I backed off the screws and blew the sawdust out.

    As for the Red Locking Lever.... I have not used it in over 3 years and I have over 1000 hours on 2 of my 4 machines. Not needed.... Overkill..... Yes, a good in Theory Idea but the jacking screws don't rotate by vibration and the length of the sleeve bearings on the 4 smooth rails don't let the head twist... So no, not needed...

    In the shop at 6 AM.... Going to be a HOT day.....

    Favorite Saying.... "It's ALL About the Brass Roller"..... And "Use MASKING TAPE" for board skipping in the X or breaking bits.

    Hi Al

    I also rarely use the red lever. Mostly because I have a dust collector that obscures my vision of it so I simple don't remember to use it. No problems so far.
    Sometimes I'm just totally underwhelmed!

    I get this error 2 one thing that i have noticed if you have a lot of x play in the rollers the sensor will not hook into the key and it will never work, this is the status of my newly rebuilt machine from LHR.
