I have an alarm "2 - excess servo lag Z" when attempting to move +Z direction.
I believe I've narrowed the problem down to the top board.
There are 8 test pins at the top-right corner of the top-board that represent the voltage to the large transistor modules in the drive. Each of these pins allows checking of the signal down to the transistor modules in the drive.
One of these base signals 2B2 (channel 2 is Z axis) is not firing. The voltage stays at a negative value when attempting to move the Z axis in either direction.
At this point, I believe the problem is a bad DK-463 module for that particular channel. Is there any way to check for a dead DK-463 module using a quality DMM? In circuit, or on the bench?
I'll order some spare DK chips, but I'd like to know if that's really the issue before I stop investigating.
Thanks for any and all help and suggestions guys.
