cut motor

[peep]

I have the DC insert removed during testing. I can not use the computer module, because that is what is wrong with my A model.

Well that does not help you out at all. Dang it!!

Swap the Cut Motor... I bet that is it... If you search you will find a few low hour "C" units that had Cut Motors go bad.

Since this thread is called "cut motor" I have a question. I've seen something here on the forum before about this problem but thought by now LHR would have figured out how to fix it. While doing centerline text my machine stops, not all the time just once in a while and usually only once during a project. It says check cut motor, I hit enter to continue and it finishes the project with no problems. I just updated my software about a month ago. Does anyone know what is going on here when this happens?

I get the same thing with the centerline text function. I thougt it was "normal" because it happens on just about all of my text carvings.

I must admit, I am a little bit reluctant to swap the cut motors between the C and A models. Is that not a major job that could make lots of things go wrong? How big and long of a job is that?
No other easy ideas to check?

What is the normal life of a cut motor? with regular brush changes every 250 hrs or so?

[unitedcases]

Mine made it about 1300 hrs before I changed it out. That was with regular brush changes.

No it really is not a major job to swap out motors. There is 3 screws that hold the motor to the frame, disconnect/remove the flex shaft from the motor (for testing purposes I would leave the flex shaft and core disconnected from the motor) and the wire connections to the motor.

One other thing you could do to test the cut motor is to make up a testing lead to go directly to the motor. An extension cord with the end receptacle cut of so you can plug the wires into the two barrel connectors is what I used. Just make sure you leave the cut motor attached to the machine and slide the flex core out of the motor.

When I was trouble shooting the machine I was working on I actually made up some test leads so that I could check/test the circuit from the X board through the cover switch up to the motor. It took finding small connectors to make the connections to the wire leads.

Not HW tech, but I thought a bad xterm could mess up the motor. So if the issue is the xterm are you risking messing up a second motor?

fwharris,

Are you saying that the cut motor runs on straight 120ac from the wall outlet. If so I can test that very fast, just want to be sure first. I have a meter, test clips etc...
