1DOF rig & FFB joystick

I got a question in youtube and some of guys may have the same question. So I would answer here.
Q1)How to enable FFB in War Thunder?
A1)Please refer the link below.
https://forum.warthunder.com/t/forc...joystick-is-not-recognized-by-the-game/137635
Q2) Only a periodic vibration effect or no spring effect
A2) As my experience, WT generate an effect based on speed, air flow and crush.
E.g.) High speed makes joystick move harder, roll action makes negative torque, no effect for firing guns etc...
It looks spring effect was not generated by War Thunder. ( I make sense it because real plane does not have it) So I decided to add it in my ArduinoFFBJoystick code.
Here is the code:
effectparams.springMaxPosition = JOYSTICK_AXIS_MAX;
effectparams.springPosition = proc ;
Q1) How I can check my FFB device working?
A1) Please use diagnostic tool. I am using this:https://www.fs-force.com/support.php
If diagtool could not detect your FFB device, it says "No force feedback joystick detected". If detected, you can find list of supported effect in 'Diagnostics' field. If you compile my code it says
"Enumerated Joystick : xxxxxxx(Your joystic name)
Supported Effects :
- GUID_ConstantForce
- GUID_RampForce
- GUID_Square
- GUID_Sine
- GUID_Triangle
- GUID_SawtoothUp
- GUID_SawtoothDown
- GUID_Spring
- GUID_Damper
- GUID_Inertia
- GUID_Friction
- GUID_CustomForce
Creating effects for xxxxx"

Then please check 'Spring center' check box to start appling force to your joystick.

I made 360 degree encoder from scrapped potentiometer and AS5600 position sensor breakout board.
The potentiometer I used: https://ja.aliexpress.com/item/1005001708276947.html

Top left: Opened potentiometer. Red area needs to be removed.
Top center: Grew magnet comes with AS5600 at center.
Top right: Create mount plate.
Bottom left: Put it togethr and put into potentiometer
Bottom center: Done

I am updating my FFB joystick because of facing an issue of slipping rod. To fix this issue, I need to change my rod from alminum to iron and apply Anaerobic Adhesive (3M TL90J) between rod and motor coupler etc...
And I am going to use this encorder.
Please find attached photo. This is the base of my FFB joystick. I will upload some photos about mouting motor etc afterwards.

From left to right. Rod φ is 10mm.
1.Motor coupler (already applied Anaerobic Adhesive )
2.Linear Rail Shaft Guide(2020 Alminum profile is already mounted)
3.Two Pillow Bearings
4.GT2 timing pulley (80th teeth)
5.Linear Rail Shaft Guide

Finally x and y motor was mounted like this.

X axis encorder build and mount to FFB base.Please find attached photo.

Left : Parts list. Arm needs 10mm hole for mounting potentiometer.
Center : All parts are combined like this.
Right : Mount it to FFB base (Y motor was removed.)

Y axis encorder build and mount to FFB base (part 1).Please find attached photo.

Left : Motor flange (φ10mm + Key)
Center : Put double side stick tape. Yellow wire is for some space from edge.
Right : Place timing belt. Holding by rubber band over night.

Y axis encorder build and mount to FFB base (part 2).Please find attached photo.

Left : Motor flange with timing belt.
Center : Attach stick part (2020 alminum profile) to flange and mount it to motor axis.
Right : Put it to FFB base. You can find encorder (most right) which was purchased from Ali Express.

This is a short video how it works.

This is my FFB controller. (Top and bottom view).
You can see Arduino Leonald (left as joystick controller) and Mega2560(right as PWM motor control).
Code can be found in my GIT. https://github.com/GNZ-3/ArduinoFFBJoystick.
Schema diagram in GIT is little bit different than this photo. .

Controller board was mounted on my FFB base. Please see attached photo.
I will mount this FFB base into my 1 DOF rig. Please wait for my test filght movie.

Test flight again. Stick moves without my interuction.
