Please, have a look at this vid: Vertical Video Syndrome - A PSA.

Lovely how you just built stuff and don't let a lack of (specialist) knowledge stop you. You probably do realise that this will not be the best 3D printer you can make?  I see two major flaws with it: speed and shinkage. A heavy CNC machine will not be able to get the speeds/acceleration you need for quick 3D printing. You could try to print at 50mm/sec (pedestrian speed for 3D printing), but the heavy mechanics will require relatively low acceleration which means loss of time to get up to speed.
The other thing is shrinkage. At small object sizes shrinkage is not so bad (for PLA), but the larger your objects become, the more the internal stress will try to lift up the corners of your objects, leading to warped and/or failed prints. Especially with this large table of yours, you'd be tempted to make large objects, that will give you some challenges.
If you have not already done so: buy a good quality hot-end (prusa, E3D), and put a large nozzle (0.8, 1.0 or 7x 0.4mm) on it if you want to print larger objects. Stick with PLA unless you install a heated bed.
But most of all: keep having fun!

If you think PLA comes from 'genetically modified maize' you are sadly mistaken and utterly ignorant about genetic modification: the two are not related in any way. PLA is made from lactic acid (as the name implies) and that lactic acid is in turn derived from sugars that in turn can be hydrolysed from any starch containing stock. Saying that PLA is made from genetically modified maize has about as much truth to it as saying that you told that untruth with (some of) the last breath of a murdered man.

ah, ardupilot/copter has been ported to something more affordable. 200USD is quite some money for a pcb with components worth ~20$ on it, so this is a good development.

Been looking for an excuse to do this one for a while. Happy Towel Day!

Sounds like good news, but aren't you a bit premature to announce this? It will put some pressure on CAA, but also on MFNZ who will do everything to stop this exemption. You have told us before, some relations are pretty close between those two orgs.
On the other hand, if you get that exemption, I'd expect them to make to reinstate your wings too. (if they are good losers.., maybe not then).

sure, and he can't really undo it now anyway.

Bugger, this comment was meant on the 3D printing vid, not this ROV stuff. Probably thick fingers on my part...

seems a little far fetched to make precise things, but a very nice concept nonetheless. Mark your outline with a laserpointer and have it cut out following those lines.
