I checked the steppers and the voltage, all that seemed right.

It turned out that my belt tension was not even. Once I got both belts to the same tension the shuddering went away. I think the looser belt was allowing it to torque the center just enough to cause shuddering and binding. Restringing the belts and getting all 4 to the same tension appears to have resolved the issue.
