Hahaha yeah, still had to do handwork after to clean it up! I’m sure if you look closely you’ll see gouges I did with the sander

Got the bottom carbon fibered! 3 layers (5.7oz) on the bottom and extra square over the foil mount.
A couple wrinkles and such, but for the first try it went great!

ESC box almost done! Pretty happy with the upgrades to the CNC that helped it cut aluminum so well. Box will bolt down to a slingshot mast base with the inside holes and mount on the board with the outside holes.

Where the wires going to come into the box from the mast?
From the picture above that box will point downward. Need to make sure water doesn’t come up through the wire holes and 2 mast base bolts.

Ah, I see now. I wonder how much heat will hit the board…
Yeah I see what you mean. I think with the amount of aluminum between the ESC and board I got a pretty good thermal mass before it gets too hot, but I’ll be monitoring that for sure. Just have to stay on foil for 60 minutes without touching down to hit the worst case!
On my old board with an arc200, I hardly had any aluminum exposed and the temps always were always in a good range.
, but you can see the ESC box there:
Great work! Do you have any more info about the DIY CNC machine? I have been thinking about building a small one, but perhaps have my bar set too low.
Mine ended up being similar to the AVID cnc pro line, except ballscrews on all axis instead of rack and pinion.
Here is one of their smaller ones:

If you wanted to build one from scratch, there is a lot of learning to do looking at designs on cnczone: DIY CNC Router Table Machines
Not sure what I would recommend for a smaller CNC. The cost at least for the style I got isn’t that much between a smaller or bigger one. Some people have luck with the china 3020 or similar, but maybe there is something better out there now for that size. All depends on what you want to do!
Have a look here plus the Black Friday (pre) sales:
There are a lot of options bout there now. One of the nicer variants I have seen is the customised sphinx 55 from open builds Sphinx 55 on MGN12 linear rails | OpenBuilds
I run sherline mills for my smaller parts, but am now looking at building my own bigger variants that I can cut much faster on.
Looks good, actually it looks very similar to the ESC/electronic box of the elevate efoil upgrade kit that is available since 3 months from www.elevate.rocks at approx. 199€ in aluminium anodized!.. They made it adoptable for trampa, maytech and flipsky VESC. I use it with flipsky and it works perfect. Never got above 50° temperature even if powering 3,5Kw.

Yes I was partially inspired by that and it looks awesome! Before I was designing something that would be inset in the board and I saw yours and thought I’d try something similar. Probably would have saved me money and time to just get that, but I wanted a good project to try and cut aluminum on my cnc.
Main hatch didn’t leak using the @michion method of a silicone pour.
Did have some leaking in the ESC up through the mast. Luckily ESC is fine and my conformal coat worked. Took it all apart and cleaned with 99% IPA and put another layer of conformal on there. MG Chemicals 422B/422C is great stuff!
