Check cutting motor

[RC Woodworks]

Lol is that possible for a truck driver to sound like a house wife!!! That is interesting that you received a close cover also. When you replace your new RPM sensor let me know if the close cover shows again. I hope yours will be the RPM sensor. CW replace one for me and I replaced 2 and still get the CCM. I also checked for the magnet. I have been wondering if there is one or 2 magnets?

I really want to know if the CCM issue has anything to do with the close cover issue? I tighten up all my cover switches screws and removed that ribbon cable behind the cut motor and my CC went away.

But after I installed the new RPM sensor and got the CC. I put the old RPM sensor back in and the CC went away. But did keep appearing at the start of a project. This time it allowed me to press enter and it would start and get CC press enter. This happen 4 or 5 times, that is when I removed the cable and called CW. I tighten the screw and it went away. I put the new RPM sensor back in and I got the CCM again. So I am getting a new cut motor.

Terry I am glad all the input of the other members has help you. I know I have learned a bunch from the other members!

Well I put the new rpm sensor in and I get the same ccm message about halfway through the project, but the close cover message is not an issue now. Darn am I looking at a new cut motor?

The check cut motor message usually comes up when the motor is running more slowly than expected. From the software's point of view, this could mean the cut motor is not running properly or the sensor has a problem. We assume it will be fairly obvious if the cut motor isn't running, so if you opt to continue after the cut motor message then we assume the sensor is bad and stop actively controlling the motor for the duration of the project. Since motor control is off the motor may indeed spin slightly faster (or slower) than normal. This should not damage the machine.

There are several possible causes for this problem, so do contact CarveWright support for a resolution.

One useful piece of information is what type of operations are you running when you get this message? Are you doing a regular carving, and if so is it deep or shallow? Or are you carving a vector path with a large bit?

It might be possible that the cut motor is running at a lower rpm than it should before the cut motor message and after the restart it runs at the proper rpm. I just notice an audibly higher rpm after the restart. I am just running standard sign carvings at .125 to .250 depth with a 1/16 carving bit.

I just carved a 2 hour project and 78 % through it got the CCM fault. The project finished after hitting Enter. But the cutting head and the flex shaft temperatures raised about 20 degrees (by hand test, I don't leave my CC alone as this is my #2 machine and still can't get an odometer reading). The RPM never slowed down after the CCM fault. I raised the cover 3 times during the last 22 % to let the thing cool down. The cutting head and shaft was not to hot to touch but you wouldn't want to keep your hand on either for more than 15 seconds.

I was carving an imported png in a 3/4" board at a depth of 1/8" if that helps.
