I thought about adding a couple of relais to operate the vac / the router. I’m also using standard stepper drivers that come with a certain size. It may well be that I could mount these all to my X-beam, but then I would have to protect these elements in a box (well, 1-3 boxes I’d guess) as Marvin showed here: Lowrider-3 aluminum strut plate - #31 by marvinlange
