My board sensor question (yes, another board sensor question)

I had a problem with the same thing check the wires from the cut motor make sure they not stinking up stopping the truck from going all the way to the plate.

The bit plate problem is usually caused by the bit plate needing a clean and lube. Sometimes the problem can be the z motor hitting the cut motor wires in the top left corner of the machine. Play around manually moving the carriage to make the bit plate pop out. You could get a feel for what is wrong.

Yup! It was the wires for the cut motor. I didn't push them over to the side after assembling the head cover.
Now then, there's just one more little thing. I keep getting the "Please close cover" error.
The cover is solid on its pivot and the error goes away if I close the cover a couple of times, but comes back in a few minutes.
Can the cover be moved a little toward the switch on the left?

Listen for when the switch clicks. If it clicks before the cover is all the way down, it might be a poor switch. If it clicks right at the bottom or does not always click, you may be able to tweak it by loosening and re tightening the screws which hold it.

Mine does that because my stand is slightly tilted toward a floor drain on one corner. I added a tapered door shim under the leg of my stand to fix it. Test your lid by closing and pushing down on one side then the other , or leveling your stand. I think there is a little give in the placement of that switch. Just loosen the screws and try moving it forward.

The plug for the Left Side Switch CAN be inserted 180 degrees out giving a Open cover. White wire toward the center of the machine when correct.

Good tip.
Mine's OK, though.
Funny, sometimes I get the error and sometimes I don't.
I'm considering putting a small dab of epoxy on the plastic tab that actuates the switch.

Since it is now "intermittent" and not "all the time open cover".... we have a different line of thinking...

First thing... When you removed the upper cover you need to be aware that the clear plastic cover does not have a mechanical stop in the closed position. So if you remove the top cover and move it to a table and DON'T support the clear plastic part, it rests on the SWITCHES. And when it rests on the switches it can damage the switches... Either by bending the contacts or cracking the plastic on the black cover where the left switch mounting screws are letting the switch be loose and intermittant....


Second is the screws for the clear cover hinge pivot point can become loose.

I have a loose worn cover... My fix is a Seat Belt... I pull the plastic cover toward the switch and place a strip of tape over the switch area between the clear and black cover. When the cover is down it holds the clear cover taunt to the switch.

I appreciate the thought that a worn or loose cover can cause an error message and stoppage. However, my cover isn't worn. It is tight and seems to be fitting properly. Moreover, I have tightened the screws for the hinge and the switch, attempting to move them closer as I do it.
My "B" machine has been inactive for some months for various reasons and when I went to use it again these events started with a "Clear Board Sensor" error.
Its been a series of small and large problems ever since.
I do feel better about maintaining my machine myself, though. I had some experience with a variety of more or less complicated machines while I was still in industry. After taking my CarveWright apart I feel pretty comfortable with doing repairs and I've learned about the little things that can crop up.
I also appreciate the willingness of others in the community to share their knowledge and experience.

I have a clear board sensor problem also. When I try to run a program (any program on my card), the head homes OK, I then press 2, the head moves about 2-1/2" to the right and stops, "Clear Board Sensor". I have checked the sensor with keypad and reads 149-150.
I have replace the FSP cable and reformatted the card. I have an "A" machine converted to the 14 pin boards and cable. What can I do?
