Hey guys.

Any chance I could bother you for your input again.
Worried about my enclosure being to small, and getting EMI noise problems.

1. Is the VFD in this enclosure a problem?

Motion control and Breakout board would be mounted on a shelf above the drivers.
I have bought belden shielded mains cable for mains wiring within the enclosure.
I will also use the shielded belden cable for connection to the spindle - Should it be grounded both ends i have read contradictory advice?

2. Should i be using shielding the power / signal lines to the stepper drivers from the transformer / breakout board within the enclosure ?

3. Does my grounding look right in the schematic ?

Thanks for any tips.
Martin
