Larry-
I installed the repaired drive today and it is working.
I am still having issues that you might be able to help me with.
The other x axis drive is still faulting. I am getting multiple LED error codes. It just depends how much I screw with it and the settings I use. The codes are 5,6,7 flashes.
Here is what is happening--
if I dis engage the bad servo from the rack and have it spinning freely, and only the one side driving the gantry, it moves up and down the table with ease. Gantry sways back and forth, but that is because it is being driven from only 1 side.
At this time, I am watching the dis engaged pinion spin and it is very jumpy.
The servo is connected to a duratrue gearhead, so I removed the servo from the gearhead.
With the servo just spinning by itself, it is still jumpy. I put a mark on the case and aligned it with the keyway. This is at 11 o'clock when you look at it.
when the servo turns counter clockwise it is very smooth and steady until it get to about 7 o'clock. Once it gets to 7'oclock it violently and rapidly spins to the start at 11 o'clock position.
It then oscillates a few times, then continues to the 7 o'clock position where it continues again.
with the power turned off the servo spins freely and evenly. With the power on, it locked in one position, but I can force it to move.
any ideas?
