    dyn4 servo creeping or twitching along by itself

    I tried wiring in the recommended approach for servo disable signal connecting the 14v pins together on the J4 connector and connecting the ena pin 15 to pin 1 . this approach worked on the X servo and the z servo but my y servo started to do a twitching creep that continues any time the servo is powered up I disconnected wiring I had put in first to the y servo then to the other two thinking it was some sorta noise thing but the twitching creeping continues any time the drive is powered up. Any ideas? thanks Chris

    Dmm's tech Tianyu, suggested switching drives or cables this lead to finding a poor crimp on the y axis cable from the breakout board to the dyn4 on the breakout board end reworking the connector solved the problem.
