Honestly if your going to go through all this effort to make this work, and already have a pi, I would suggest instead upgrade the control board to something with extra fan headers, led heads, etc and switch to klipper, there have to be guides out there for your specific printer

Powering the fan from gpio pins probably isn't going to work out well either, they are 3.3v and 5v. Powering the fan from the PSU is going to be similar to powering a pi off it, I believe you should step the voltage down to what each needs, where the fan is 24v I think the pi is 5v. Your PSU is probably 115 or 220 v. For connectors I would expect to have to redo them yourself with micro fit, molex, jst or w/e you want and can get. On some of mine I just did single pin molex on the pins of the white female connector for fan headers, it doesn't lock but it works if you don't have a lot of movement. This page is awesome for connectors info https://www.mattmillman.com/info/crimpconnectors/common-jst-connector-types/

Per https://help.prusa3d.com/article/xbuddy-and-loveboard-electronics-wiring-mk4_413095 it looks like you dont have any fan headers, you might be able to repurpose the unused ambient sensor header but no clue sorry. You might try splicing off the part or hotend fan? If you really wanted to use the dc input you might need a voltage step down buck converter or something depending on what your PSU is putting out

You might be able to but you really shouldn't. At the best you wouldn't have control over fan speed. Find the wiring diagram for the board and use a fan header

Oh hey I kinda helped get this started in a very round about way! Nice to see the fluid integration, maybe if I do the mainsail one, someone else will do it a better way lol. I've not been printing much lately but set spoolman up a while ago on the pi running my voron and it's been great.

How are the Spigen case for drops? Is it one type of material or two like the google? I was trying to avoid glass over the camera and just go with a sticker/skin

Magnetic is really important for me, how is that case with drops? I imagine it's pretty stiff/hard?

So far I love it. I'm maybe 60/40 or 50/50 external to internal. I don't use a lot of apps though, I mostly stick with doing things through the browser which doesn't have a lot of issues using up the screen. When I do use the internal screen, it tends to be two apps at once, like podcast player and workout tracker, etc, so again no wasted space. My biggest gripe is the home screens and the taskbar. I had to switch to the Android 14 beta to fix the task bar with third party launchers. The pixel launcher forces too much google down your throat and you can't have distinct layouts for the external home and internal. I've settled on total launcher for now but it has its own minor set of issues. 14 seems to have fixed lot but odd stuff, like the pixel launcher, seem to be missing options foldable wise.

I've had under extrusion, caused by too high speed or pressure advance settings look like this, does it show up if you slow down?

One I don't see people mentioning is the walking dead saints and sinners. I haven't played part 2 yet but I put a lot of hours into the first one

That last point is a big one, for me putting 30 hours into a single VR game feels like putting 100 into a pancake.
