Upgrading my OMIO X4 machine to an AXBB-E controller and new enclosure. I'm a novice and have tried to learn as much as possible in order to take on this upgrade project. This is my planned basic wiring setup, would appreciate any feedback

Few notes:

  • Double-shielded cable will be used for all signal cables and they will all be grounded and terminated to the Ground Bus bar.
  • 5 Pin GX16 connections will be used so the motor cable will also be grounded
  • VFD & Power will be in top half of enclosure and AXBB-E & Stepper Drives will be in bottom half to try and keep distance high and low voltage cables
  • Turning on mains power switch will only power the 24v, 5v, Fans & AXBB-E
  • Pressing the latching Stop/Start button will turn on the contactor which has a 24VDC coil that will then feed power to 48V, VFD and Stepper Drives
