3D Printing Guide w/Creality Ender 3 (v2)

This is just a dump of discoveries, experience, and general insights.

ℹ️ Does not contain any assembly related information.

ℹ️ A lot of this applies to 3D printers in general.

Divided into the following documentation, in order:

These comments are based on a few years of experience working with WSL. It's based on this tutorial:

https://blog.ropnop.com/configuring-a-pretty-and-usable-terminal-emulator-for-wsl/

And are basically updates to make it more relevant.

Opening a shell

In the past, to make the WSL run a command from cmd or somewhere else, you had to run the bash.exe program from windows, which fired up bash (and always bash) in the WSL and made it execute a command.

Due to a beautiful bug in Chromium, it turns out you don't need this binary patch and can **enable** subpixel positioning by asking Chrome **to disable it**: https://bugs.chromium.org/p/chromium/issues/detail?id=824153#c39

Needless to say, I won't be maintaining this gist any longer.

Frida logging helper

For adding temporary logging to help understand behavior. For when it is impractical to use Frida to instrument Frida.

Choose one of these and copy-paste it into e.g. lib/interfaces/session.vala, then use log_event ("name='%s'", name); to log.

When something appears to be hanging, try applying: x-async-debug.patch.
