So my machine lost position two days ago during normal routine. Went to trouble shoot and noticed the LEDs on the Geckos are dimming during jogging. Got the multimeter to test voltage. Did several tests, but tested the voltage from the power ground terminal on the gecko (far left) to the terminal right next to it (says 24-80vdc) and got a reading of about 53 volts on all 4 geckos during a normal file run. Granted, the router was not running during this test, but it seemed to run fine.
I did check out the y motors to see if there was binding, which might result in a higher amp draw to move the motors, but they are fine, no binding.
No idea what would cause a Gecko drive to have LED dimming while jogging.
Ideas?
