reading about your problems and posting my own makes me really feel thankful i found this web
site i know we are all in the same boat. i would help if could but Thanks CODY for trying to help
us all!!!!!!!

My contact in Indy has gone out of business. I have dealt with the company that RRL suggested, and they did an outstanding job on the motors we sent back to them for repair.

Thanks for the info RRL. I havnt called them yet. But will next week. I had to step back from this problem last week.It was making me crazy. I loaded the quads and dirt bikes in the truck, and went to the dunes for a long weekend. Darn that was fun!! This weekend I have a few projects and should be focusing on this by late next week.

darren, This forum has been a blessing to me so far.

I finally started back on this problem this week. I made a sort of press like fixture and was able to shear/press the magnets loose from the housing. Tonite Im going to try and figure out how to locate the magnets correctly and see if I can get the motor to work again.

My Kitamura is working again!! I was able to figure out which end of the magnet was positive and alternate the magnets in the housing. The method I used to figure out which end was the positive end involved a Volt Meter. Im pretty sure it was set on 200K for DC volts. With the magnet layed out in front of me and not closer than 3' or so to anything metal/steel. You can hold the positive line to one end of the magnet and the negative side to the other end of the magnet. Then switch ends. I got a slightly positive reading checking one way and a even slighter negative reading. Positive reading was between .4 and .8 volts. Negative reading was between .1 and .2 volts. I marked the end that I had the positive connector on when i got a positive reading and then alternated the magnets, leaving them loose for the trial run. The motor ran with the magnets in the correct place but not glued in. I glued 2 magnets in fri nite and the other magnet in sat a.m. I got the machine running in the late afternoon and everything is working good.

I now can notice a very slight squeek/clunk coming out if the Y axis motor. I guess I will be taking that motor apart soon to glue the magnets back in place in it. I will most likely replace the bearings in that motor also.

The Y axis overloaded and shut down while I was running a program over the weekend. I took the front of the machine apart and pulled the servo motor. It only had one loose magnet, and the bearings sounded good. I cleaned everything up and glued the magnet back in place. (keeping track of how the magnet was located this time) After putting the motor back together and back in the machine. The machine is up and running again, and very quiet while cutting and in rapid traverse.

Now I can only wonder what my next learning experience will be?

Thanks for posting how you finally fixed the motor. Interesting about using a meter to check the magnets, I will keep that in mind if I ever need to do the same.
Thanks

My pleasure Petro! Its the least I could do for all the great info Ive got from you and your forum. I will stop by here when Im on the internet, and see if I can help with any problems.

I had also heard you can float a magnet in a small pan(plastic) in a large tub (also plastic) water. Supposedly the magnet will spin so the + end is pointing north. I could only get one of my magnets to position itself correctly with this method. The Volt meter method is pretty straight forward. Its even possible to check the magnets while they are glued into the housing.

Im getting the same 01 Overload message. It happened about 20 seconds after hearing squeaking sounds from the Z axis. I am not sure if the magnets came unglued in the Z motor or if the bearings have gone out in the motor or, maybe the ball screw. Im taking it apart this morning and will post what I find later today.

I pulled the motor and took it apart. Magnets were fine, lots of dust in the brush area and 1 of the bearings was noisy. I replaced both of the bearings and cleaned up the inside of the motor. Put it back together today and Im getting the same "02 VRDY OFF" Servo alarm I got when I messed up the magnets last time. . Not sure why because I didnt touch the magnets this time. Kinda confused at this point so Im going to pull the motor back off and see if I messed something up.

If anyone has any ideas Id be happy to hear them.
