Didn't realize how expensive enclosures could be.
Saw this steel tool cabinet at a store nearby.
Its 28" x 28" x 12" for $80.00 Not very dustproof since there are no seals, but that's an easy fix.
The shelf is removable.

Would that suffice?

Thanks,
Charles

Yes you should use a Power Filter on the input side of the VFD it needs to be rated for the same size as the supply Circuit more is better

The VFD should never be turned off, the Main Power should not be in the EStop Circuit, only the control or fault Circuit is used in the EStop Circuit, if you cut power to a VFD and the Spindle is running you usually smoke the Drive or the Spindle this only applies to these high speed spindles

The cabinet looks ok but you will have to add a Back Plane this is done by adding some standoff's and attaching the Back Plane to the standoff's, ( Aluminum Plate )You could leave the shelf as you could separate the power supplies and VFD from the low voltage electronics

The door could pose a problem as they need to be fastened some how so the can't be opened easily, a fan should keep most of the dust out

What is the purpose of the backplane?
It's not electrically isolated from the cabinet, is it?
again, thanks.

Back Plane is what you mount everything on all electrical cabinets have a Back Plane of some kind, the Back Plane is not painted for better Grounding the Back Plane is Grounded with the main input power supply Ground and then the Box and Doors are Grounded to the Back Plane
