I made engineering drawings to help with making each part and for easy assembly. I researched a few different designs online but couldn't find anything that was quite what I wanted so designed my own. I decided the best solution was store the printer in a zero-gravity vacuum chamber, but as I couldn't afford that I instead decided to build a simple enclosure. The printer is loud, not ridiculously loud but enough to be annoying when I'm trying to watch YouTube on my laptop next to it. Like everything in my house the printer quickly gets covered in dust, which doesn't really affect the function of the printer but doesn't look very nice and it's a fiddle to clean all the small parts. The extruder head drops when the printer loses power, everyone with a Cetus mkI knows this and in June 2017 an official fix was released which solves it. Although I was very happy with the printer I've found a few things I wanted to improve: I've played with a few materials and found which work best for me and the printer (PLA for quick prototyping and PETG for more durable parts). Over the past year I've printed several useful items (and many useless ones). The Cetus seemed to bridge the gap between reasonable value and sensible quality. It works perfectly with the stock Cetus3D one, but no settings in the config file have got that thing reading correctly on the Titan Aero stock one.In May 2017 I bought a Cetus 3D printer, I'd wanted a 3D printer for a while but didn't want something that I'd spend more time fixing than using. The only kink yet to worked out (one day of work, so.) is the TinyFab is NOT happy with the thermister that comes with the Titan Aero. I still need to get the heated bed installed as well as the autolevel "stuff" installed and configured. Right now, it is mostly happy as a clam with the Titan Aero extruder mounted (the mount I made leaves the tip of the nozzle at the exact same place as the stock print head does) and the TinyFab driving it.
That was a bit interesting and wouldn't suggest it unless you are very comfortable with your soldering skills. I also yanked the two resistors for each drive that sets the drive current and soldered down some TINY pots to make the current limits adjustable (again, more for the upcoming CPU board). I wanted them because they are rated to higher current AND they have about 1/3 the Rdson values which should make them a bit cooler running. They are pin compatible, but the DRV8825 DOES have a bigger ground pad on the bottom. While I was messing with the board (getting ready for my TinyFab and Titan Aero to come in), I also replaced the DRV8824s with DRV8825s. The heater has a bit more voltage and current, so it can heat up faster as well.

You have a bit more voltage to the stepper drivers (we used to hit "4.5V" steppers with 90V supplies on the semiconductor manufacturing equipment I was responsible for) which is generally good. So, I hooked it up to my 30V bench supply and dialed it up to 24V. All the 5V and 3.3V stuff was fed from a DC-DC 5V converter that could handle way more than 24V.
After reviewing every IC on the main board, I found nothing on there that couldn't handle a bit higher voltage.
