Hi m_c,
I connected my scope last night and got no ripple at all on the 24vdc power supply. Still need to check my 5 and 12vdc.
Yes i have done several tests. Which include testing each drive with both axes. And the drive in question(zaxis) will show the same issues when connected to X axis servo. The X axis drive has no issues, or at least none that i can tell during tuning, running the heavier Z axis.
Right now iam going back and forth with support from DMM to eliminate any possible noise issue. As they believe this is causing the problems of tuning with Kmotion. But i have also noted that when using there AutoTuning software the Z axis drive always comes up with way lower settings,gains,accel and such. But the X axis drive does not.
So while iam waiting on some filters for the main power input to drives iam double checking things.
