Motor tilting very fast

Hi guys,
After using Maslow for over a month pretty much everyday, yesterday my left motor made a click sound (more like a “tack-tack-tack” type of sound) each time turning left side .
As @Gero said it is important to know that I had two chain wraps in that time but on the right motor.
First reflex stop everything So i’ve checked several times the motors with the groundcontrol test everythinf seems fine and then 2 things happened.

  • first batch of tries everything went fine on the groundcontrol test, each motors seems in perfect working order.
    -i get on with the cut and then a message from groundcontrol said that my sled wasn’t keeping up.
  • second batch of test : the left motor failed the left side turn 1 time in 3 tests.
  • Try go on with the cut and then the same message came up instantly.
  • third batch of test : Test Failed on the left motor for a left side turn 3 times out of 3.
  • Then I tried to switch the motor, the problem seems to follow.
  • I’ve also open the cap of the motor to see if there was anything loose like @rasiel , but everything seems fine.
    So i’ve think i’ve busted one of my motors and reordered a couple just in case.
    Do you have an idea of where the problem can originate?
    I use the standard frame and a ridgid router.
