Electronics newbie - I'm upgrading an old Techno Davinci router with a Gecko G540 drive and an ESS Smoothstepper. Wondering if there's any reason not to put them both in the same enclosure? I'm using the original power source in the Davinci, which is mounted in one of the gantry uprights. The gantry is fixed, the table moves, so I am planning to bolt the box to the side of the gantry

Also would like to have a 120v relay to turn on the router motor, can that also be in the same enclosure?

My concern is whether there are any noise problems with any of these components that require isolation.

All and any advice appreciated, thanks
Richard
