That’s a lot of progress! Good job. I can’t wait to see it working with your MOD

That looks amazing. How did you do the lettering?

Thanks, @Austin73!
This is how I did the lettering: (1) spray paint the chassis, 2 or 3 layers, wait for the paint to dry 
(2) put a masking tape over the place where the lettering would be; (3) laser engrave the letters on a cnc machine right through the tape and through the paint, so that the letters are etched into the paint; (4) fill the etched letters with white paint (I borrowed my wife’s white acrylic paint marker - if your wife doesn’t have one, she should get one, so that you can borrow it, this is crucial); (5) while the white paint is still wet, gently remove the tape, if needed clean up the letters’ edges with a piece of cloth or a cotton pad (you should know where your wife keeps those before you get to do the lettering); (6) spray over with transparent acrylic coating.
It takes some nerve and steady hands, I experimented and practiced on a spare piece of aluminium before I got to the unit itself.
It’s a painstaking process so if anyone knows a better way of doing it please please let me know.

I need to borrow her laser cnc machine first but not sure where she keeps it!

I say start looking by checking her garage or your father-in-law’s toolshed. Them women be very cunning when it comes to hiding machinery from their lawful husbands: I still can’t find where my wife hides her 3D printer for the life of me!
P.S. There are not-so-expensive cnc machines on Aliexpress that can do the job. This is a treacherous path though, it’s never enough and you always want more, just like GAS with guitars or other musical gear. Well, you kno.

Oh I know, I’ve nearly completed Aliexpress!
Gotta catch them all

BTW, now that I have a much more powerful laser, I wanna try to engrave aluminium itself without having to paint it. Will let you know how it turns out if you’re interested.

Yeah that would be cool

do you plan on releasing the code? I’d be very interested to build something similar in a smaller form factor.

I can try and release the code, although (a) I’m not a big expert in all concerning github, and I’m not sure I want to spend a lot of time studying it, (b) I had to do quite a lot of customisation in the CC library itself, so my code may not be backward compatible with the possible updates if/when the guys from MOD release an update, (c) my code is not very well commented, so it may be hard to read, (d) I was adapting the code specifically for Arduino Mega, a few things are hard coded.
But I’m happy to share the code, of course, and answer reasonable amount of questions

no worries - if it’s easier just zip it and upload that. I’ll probably use it as a reference point.
Last I checked the CC stuff was a little hit and miss - even with the dev board. At least the concept is kind of ready.

Nice! What Arduino board is it based on?
The chassis is 3D-printed plastic?
Pots or encoders?
What’s the planned use for the flip switches?

Ok, here’s the code - an Arduino sketch and a heavily customised Arduino control chain library, for reference only, on an ‘as-is’ basis.
I’m open for any suggestions/improvements though.
NB: switching of snapshots with a control group does not function properly and causes the code to hang. The MOD guys promised to fix this in 1.13 release, I’m patiently waiting.
