Cut motor stopped in the middle of a project and it wont restart

[onetexasoldman]

I am having the same problem at 25hrs and 40 min. Was carving and stopped said to clean rails (no code) did that and it started to carve but motor wasn't going. Checked everything you have suggested. Wires back of motor, circuit board on bottom, check cover switch with meter, ran options test shows motor running but it's NOT! Blew motor out tapped on it with back of screwdriver. Motor turn fine by hand. I do have another machine with 600 hrs on it so this is not my first machine.

I have a local user with the very same issue. Changed out the X termination board and got the very same results. Only thing noticeable was the connecter at the board for the wires going up to the cut motor. The white wire terminal in the plug was blackened. All circuits ohmed out good. We hot wired (extension cord) into the cut motor and it spun up just fine.

That new insert you make sure is great hardly any chips left after carving 4hrs

OK after all said done, and talking to LHR this morning they wanted me to send in the motor so they could REBUILD it??? I replaced the motor with an old one I had after they told me that (didn't want to void the warranty) and it works now with the tests. This machine only has 25 hrs , I told them I didn't want a REBUILT motor in the new machine so they are sending me a new one? haha Thanks for all the help I learned some more about the machines.

Yes, we prefer to rebuild it, but if you want a new one (and we have a new one) you can pay the core charge, so that we get the old one back. Based on the warranty agreement, we do have the option to replace warranty parts with rebuilt parts.

I had the same thing happen the other day. Motor quit in the middle of a carve. Totally messed that piece up. So I got out the handy Dremel and sawed away more of the plastic lid to make sure it was closing down and tight and wasn't hitting on the dust collector. I had just taken the collector off to give the machine a good cleaning. Apparently when I put it back on it wasn't fitting just like it had before and was messing with the safety switches. That did the trick. Works great now.

I know LHR has the option to replace with rebuilt and sometimes the rebuilt parts are better but I just didn't have the time to wait seeing my other machine was down waiting for parts.

Same problem here.. Cut motor refuses to run.. Checked about everything I could think of.. Blew out switches on the clear cover, checked all connections, took the cut motor out and checked brushes. The one (top) looks fine, but I could not get the other cap to come off. I'm wondering if it melted and fused to the threads inside the cap.. The user tests shows everything working.. The cut motor tests indicates the cut motor is on. Also, the cut motor turns freely with the shaft, so it couldn't be seized up. It seems to be a common problem with the machine. I hope they can give us a clue on how to remedy this problem..
