I needed a button in the Firefox UI to toggle the default page zoom level 
setting offered by the NoSquint extension (shown as "extensions.nosquint.fullZoomLevel" 
in about:config). Since this isn't likely to be provided directly and I 
wasn't interested in writing my own extension for something so simple, I 
looked for an extension that would expose about:config settings to buttons.

Deltaprintr Firmware HOWTO

These instructions are for the original plywood-frame Deltaprintr from the 2013 Kickstarter campaign or sold on the website before the release of the Delta Go. The Kickstarter campaign ran in 2013 with printer rewards for $500 pledges, and printers were delivered in 2015. They use a custom variant of the Azteeg X3 controller board. There was a vibrant community for a couple of years on the forums, designing mods and improvements, and sorting out each other's print issues. I've had mine working quite well for years.

This comprises several firmware-related forum posts; my original firmware HOWTO, my fix for stuttering movement, and Ian Brennan's [experimentation](http://forums.deltaprintr.com/index

# moonraker-users.py (by @mildmojo)
#
# Script to add/delete users from Moonraker's LMDB database.
# This would've been so much less painful if they'd used SQLite.
# But good news! They're switching to SQLite soon (posted Dec 2023):
# https://github.com/Arksine/moonraker/issues/781#issuecomment-1871333293
#
# Run this script with /home/pi/moonraker-env/bin/python. For a
# Klipper deployment installed with KIAUH, something like:
#   ~/moonraker-env/bin/python moonraker-users.py --create /home/pi/printer_data/database my_user my_password
