Requirements:

Rigid couplers (use ball bearing for flexible)
Add extra 20mm in your Z limit configuration to allow stepper stalling
Physical limiter (e.g a screw in the extrusion on both sides with equal distances)
(optional) Software current control for low noise on stalls; using TMC in this example

Functions:

Aligns the two leadscrew-driven motors only once after powerup on the first G28 command until next power cycle.

In a bat file, replace with Device Instance Path from Device Manager dGPU properties

pnputil /disable-device "PCI\VEN_10DE&DEV_25E0&SUBSYS_3AAC17AA&REV_A1\4&1D71CFEE&0&0009"
pnputil /enable-device "PCI\VEN_10DE&DEV_25E0&SUBSYS_3AAC17AA&REV_A1\4&1D71CFEE&0&0009"

TODO:

Provide pre-compiled MPTCP 5.4 kernel
Add service for xray
Add Ubond for non-TCP aggregation (link quality monitor WIP)

Notes:

Direct MPTCP is not reliable even if the path is not filtered over the Internet
Using firewall markings to tunnel each Wireguard to it's respective WAN
~700Mbit MPTCP aggregation (direct) tested on Pi 4 stock frequency with local 2 links

	ETA setup: ~1 hour.

	1. Install termux and follow https://ivonblog.com/en-us/posts/termux-compile-mesa-driver/
	2. Add startx file in home directory with the following content:

	#!/bin/sh
	termux-x11 &
	udroid -l xfce4

	3. Add startx file inside Ubuntu home directory with the following content:

	Section;Extruder;Key;Type;Value
	general;0;Date;str;14/01/2023 00:11:36
	general;0;Os;str;Windows 10.0.22621
	general;0;Cura_Version;str;5.2.1
	general;0;Profile;str;Fast-ABS (Use this!)
	general;0;Quality;str;Fast
	general;0;Extruder_Count;int;1

	###INSTRUCTIONS###
	#SSH to router & download this script (copy RAW button) and easytether (openwrt19 zip file) in the same directory using command wget <link>
	#run: sh armv7-no-neon.sh
	#Script will autoinstall, the package in the same directory: easytether-without-neon.ipk can be used for other deployments
	#Tested: Slate AX

	rm -r build-xiej43 download-s39c
	mkdir build-xiej43 download-s39c

	Download binaries: https://github.com/TalalMash/ubond/releases/tag/v0.1.1
	Disable encryption for 400Mbit+ , force DNS over HTTPS if needed.
	Temporarily running as root. (tun bugfix TODO)

	#Add this file to /root
	#For interactive adjustments and keyboard input, install screen "opkg update && opkg install screen"
	#and add to rc.local before exit 0: "screen -d -m sh -c "sh /root/adsl.sh" &"
	#Enable telnet/port-23 in modem settings, usually open by most bad ISPs
	#Replace <> fields with your settings


	while :

	Rule1 ON sr04#distance>0 DO Backlog var1=((((%value%)-20)-(EM-20))/(EM-20))-100; var2=(var10.01)LT; event sendval ENDON
	Rule1 + ON event#sendval DO publish tele/watertank/LEVEL %var1% ENDON ON event#sendval DO publish tele/watertank/VOLUME %var2% ENDON
	Rule1 1

	Replace:
	-LT with the number of liters
	-EM with the distance when the tank is empty.

	You will get percentage (level) and number of liters, accurate starting from 60cm deep tanks.
	SR-04 (water proof) is recommended for use.
