Living alone does have some great advantages and the kitchen table being an extension of the work shop is just one . . Lol

Well like mike says you have gone slight wrong way aound it really but damage is done now and it's not massive damage so we'll make the best of it. ( Could have been far worse being the TB based drives you bought which often happens.!)

Regards the Combi machine then 2 out of 3 is easy enough, being milling/engraving and 3D printing (yes Mach3 can do it) but the Laser cutting side is a bit more involved if you like keeping your sight.! . . . But still do-able just expensive and involved which is what I think stops it happening so much.
Also like any combination machine they never do it the same as a dedicated machine built solely for that purpose and if your going to invest the money and time required you will certainly want it to be the best it can be.!

Can't advise on your machine without seeing some kind of design but a few things you mention cause a little concern regards structure. 250mm Z axis is on the long side also 20mm width profile is a little skinny.! . . . Do you have a plan or drawing you can show giving some clue to your thinking.?
