On my PRS alpha, one of my X motors periodically freezes up while I'm cutting. When it happens, I unplug the motor from the driver, and unbolt it from the machine. I can turn the pinion freely in one direction, but when I turn it in the other direction, it will get a certain point, then stick. If I work it back and forth, I'm able to get it to spin freely in both directions.
It happened again today, and when I took it apart, the shaft that the pinion goes on, had actually loosened up somewhat too. I took the motor apart and a fair number of teeth on the gears inside had broken off as well.
First question is, what would cause the teeth to break? Secondly, I'm beyond the machine warranty, and naturally would just as soon not have to buy another motor - is it possible to have the motor rebuilt? Is there a gear replacement kit available?
Thanks in advance.
