Be careful that it's the electrical-compatible---ordinary commercial

If you go with a standard PC motherboard, I would get a can of clear lacquer
and apply 2 coats to both sides of the board and components.
I have aging industrial electronics in my shop that get weird in summer when
humidity peaks.
I have successfully eliminated -some- of the weirdness by sealing ou

That can be any mineral oil - they are not conductive. There are many
vids on Youtube, how PCs are put in oil and they keep working. Even
gasoline is non-conductive, so You can submerge

Of course, You can!
Create a HAL pin in Your kinematics module and arrange all the
inverse/forward kins calculation.
And then in HAL file instead of setting a certain value

Thinking about this some more, you might need to use a CRT, as LCD
displays stop working when they get cold

I have seen conformal coating but I have no experience applying it. I
would think it could create hot spots on some motherboards if it was not

Does anyone have any experience in testing for condensation issues?

I've worked on explosion proof systems so the idea of using what we
called "seal-offs" is a good idea to contain the air in the cabinets.

Thinking of true 5-axis machining with hexapod, I found that important
thing here is how EMC2 handles tool length offset.
With XYZAB kinematics I'd prefer to always have AB rotations around
TCP. But it proved that setting Z tool offset does not change the
rotation center (obviously genhexkins is no
I have seen electronics on sea buoys. It's mounted in a simple PVC
box, then all wires are connected, then it is filled to the edge with
some silicone gel, after setting, the lid is screwed on. Even all
heatsinks are completely submerged in the gel.
