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

PlatformIO: Arduino for Raspberry Pi Pico (RP2040) with Programmable IO (PIO) support

This is a set of files that sets up an environment that will compile an Arduino project and assemble Programmable IO (PIO) scripts into C++ header files for inclusion in Arduino source files.

I made these notes in October 2024 after spending a lot of time researching how to make PlatformIO, Arduino, and PIO work together.

(Not yet fully tested.)

	************************************************************************
	THIS GIST IS OUTDATED

	There's a new version published in the bitsy-hacks repo, which fixes
	some bugs. Go get it instead!

	Direct link to the external game data mod:

	/* Operator logic is at the bottom of this script; need to declare the toolkit first. */

	================================
	SCRIPT HOOKS TOOLKIT (@mildmojo)
	================================

	HOW TO USE:
	1. Paste this whole file in script tags at the bottom of your Bitsy
	exported game HTML, after the last /script> tag.

	#!/bin/bash
	#
	# rotate-audio-output.sh
	#
	# Switch to the next available audio output device and show a notification with
	# all available devices and the one currently selected.
	#
	# You may need to edit /etc/pulse/default.pa and change the appropriate line to:
	# load-module module-stream-restore restore_device=false
	#

	'use strict';
	const exec = require('child_process').exec;

	// Quick shortcut for shortcomings in `gulp.task` API:
	// 1. `gulp.task` doesn't accept a description, has to be a prop on the function.
	// 2. Since description has to be on the task function, it's harder to add a
	// description to tasks whose functions were created by a helper (e.g.
	// `gulp.series` or `gulp.parallel`) since you didn't define the functions
	// they return.
	function gulpTask(name, desc, fn) {

	#!/usr/bin/env node

	Implements the dark frame subtraction pipeline using ImageMagick described here:

	It's very slow.

	# 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):

	# 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
