A project log for Alice (3d Printer)

Fully custom 3d printer, including custom electronics.

Today is not the first day I have worked on this project, just my first log. This will be stream of consciousness and as-best-I-remember-it. I will forget things. I will get minor details wrong.

I am approaching this project slowly. I have a lot to learn, and I want to double check my assumptions as I go. Because of this, there's a lot of basics that are going to be done before it feels like I'm making progress on this one directly. I will try to explain how each thing is relevant so that the connection is made.

This log is only about the big picture. I have decided to make separate logs for the bits that I have done and have started working on/designing just to make organization easier.

So why the name Alice? I have two daughters. One of my projects not relevant for this channel is making my own computer language. Alice is already the name of a computer language, so I named it after my younger daughter. So now my older daughter gets the 3d printer. It's as simple as that!

What is different about Alice vs the other 3d printers? The kinematics and aesthetics aren't 100% unique. I will likely go with core xy, probably 3-point bed leveling. I am not going to go with a direct copy of voron or hevort or anything like that, but I will be taking heavy inspiration from them until I have some idea on how to make a fairly large modification.

The main modification idea I have had so far is in the electronics realm: many, custom-purpose control boards.

Klipper allows you to have multiple control boards, but that's rarely used, and when it is it's for things like adding 1-2 more z motors to your janky default control board. Hardly a shining example.

I want to have a control board for the hotend/carriage, another for the z motors, etc. This won't be the first ever printer to have separate control boards, not even the first with those specific ones, but that idea is certainly less explored.

Aside from that, I also have an interesting idea when it comes to wiring that I want to try out, but I'll leave details of that for when I have made progress there. (It shouldn't be long, I have parts coming for the first sanity-check of the idea literally today.)
