K8055 + Sabertooth + Wiper motors

UPDATE 06/03/2012 :

Last update is relating to the dynamic speed. It seems that a solution has been found.
That's why I add a small modification to the tutorial, to present the configuration (from libor).
I don't know if it works, and I can't test at the moment. But it worths to try.


Here are the results of french guys who decided to follow this solution (K8055 + Sabertooth) :
BIG THANK TO THEM


Interesting concept with NIKO77 : K8055 + Sabertooth + Drill motor !!!

Hi all,

After 6 months of "inactivity", I come back and I'm now working on a new protoype with 2 cards :

- VM110 (K8055)
- Sabertooth 2 x 10 A


This kind of configuration should be adapted to use WIPER MOTORS or little kind of DC motors (100W to 250W for example, like "child scooter"). Kind of Motor MY1016 or MY1018 easy to find on internet.

--------------------------------------------------
The aim of this post is to understand the basics of this king of configuration (VM110 + Sabertooth + DC motor).
And also how to configure X-sim to make it work (it was my problem but today everything is solved).
--------------------------------------------------

X-Sim compatible hardware

Command for wipers motors

hi there
i m jeanmi from reunion island, i have a new project but a problem to resolve too.

i have to command two wipers motors (direction) the signal comes from a hacked servo, it is +5v and ground
it have a feedback (pot) for position

i need a board between this signal and the motors, only one signal for two motors, they have to do the same thing

as you can see it s a simple board like dual H bridge with high Amps output, and capable to use my signal

i hope you ll help me
bye
jeanmi

brasilian cockpit

good evening everyone

my nom is Fabio Camargo, I am Brazilian and I am starting this magnificent world of simulators.

I have a small industry of cutting machines (CNC routers), and I'm finishing two simulators (no movement).

I intend to start construction of a model with two axes and using the windshield wipers.

I wonder if my drawing is a condition to start a good project.

soon I'll post it all in 3D. (inventor).

Thanks for the welcome, and anything I can help, are the will.

DIRT 1 - 3

dirt 3 crashed if I change extradata 0 to1

Hi,
I have a problem with dirt 3. If I use my sim with the dirt 2 plugin, after modification of the hardware settings my sim is workng fine. But I can´t finished each race because if I came to the finish, the game stops and and I got a picture freeze.
When I change the hardware settings back I can drive without my sim with no problems. I have no idea about the reason.
Any help would be very great.


cheers chris

Force-Profiler Simulator Control

Bass Shaker Plugin

I see references in the forum to a bass shaker plugin but I cannot find this in documentation or X-Sim. In X-Sim I feel like I extensively looked through Force Profiler.

What am I missing?

Thanks!

DIY motion simulator projects

Floriske.nl's 2DOF Playseat GT Wiper motor Project



After a lot of reading and contact with YoBuddy (thx m8!) it is time to start a topic for my first Sim project.

Since it's my first project it'll most likely go paired with a lot of trial and error and thus I'm going to take my time for it which might result in less frequent updates, but I wanna do it right the first time.

As the title says, the project will be based on the Playseat GT which I bought at about half price and was used only once for a photoshoot:



I want to build a simple platform out of birch plywood (reckon 15 or 18mm) which holds the complete structure, here's a first rough sketch (top view):



The seat arrived yesterday and I'm working out orders for other hardware atm.

Fortunatelly YoBuddy had an unused Pololu Dual VNH2SP30 Motor Driver Carrier and a AMC 1.5~EZ v1.0 PCB lying around which he was willing to sell me for a very fair price. With that the controls are settled.




For the motors at first I have been looking at some cheap (€ 55,-) winch motors:



They do about 1A/7,5KG and since the Pololu driver can handle 14A/channel continuously this would result in a max continuous load per motor of 105Kg which should be more than enough.

Problem is that the supplier doesn't know the RPM of the motor only that they do 3.2m/min and thus I don't know if they are suitable.

For that reason I decided not to order them and go for wiper motors at first. Currently I'm still trying to find a matched pair of the right type that is usable (if anyone has any suggestions ......).

So far for the first post, I'll keep you updated!

X-Sim compatible hardware

Tronic's AMC motor motion-controller with pwm/servo output

BEWARE: This version is obsolete now! You can find the new version of the AMC1.6USB here: http://www.x-sim.de/forum/blog.php?u=101&b=21.

The AMC1.5 AVR controller supports 2 full H-bridge PWM channels to drive the motors. The connections will be made in the same ports and its function will be selectable by dip switches.


The major features are:

- 10bit (1024) motor speed resolution
-2 actuators/motors support (in latest firmware 1.0)
-2 full PWM channels, 2 - 8bit pwm channels (Not implemented yet the extra channels lack of timers).
-4 potentiometer inputs (that sets the max travel angle and the proportional speed.)
-LCD support

MANUAL FOR AMC / DSMHb with X-simulator software
https://rapidshare.com/files/1960710485/AMC_DSMhb_Manual_Word_97-2003.pdf



(EDIT: I HAVE NEW IMPROVED PCB PLANS FOR THE AMC1.5 HERE: post7978.html#p7978 )

Below you can see the layout I made to be able to follow the RN-VN2 connection standards. PCB plans are included to built this board if you want. Over this layout I’ll add the rest software features to make it able to fit to every type of motion simulator. Other PWM motor controller can be used too since they use the same basic connections (PWM, Enable1, Enable2) just different layout of the connection stripe.




And here is only the bottom side layout:

avrmotionsimPCBbottom_only_1_5_a.pdf (100.25 KB)

Here is the new part list for version 1.5 of the AVR controller PCB:


And here in text format only:



Notice: If you can't find the molex connectors or you found them in too high prize, you can use pairs of simple DIP pin headers in place of the base connector or to create the data cable between avr controller and RN-VN2 motor controller. But you have to be carefull about the orientation of the connection if you plug - unplug them often. One full set of molex connectors for an AVR controller PCB, costs around 3.30 euro (14 connectors, male/female)... at least, this prize I buy them localy in Greece...








--------------------------------------------------------------------------------

Some technical details about the AVR motion controller:

Motor 1,2 run on 9bit PWM on 23,47Khz (9bit = 512)
Motor 3,4 run on 8bit PWM on 23,47Khz (8bit =256) (not implemented)
Has 8 ADC channels with 10bit resolution (10bit=1024)

Actually I drive the motor on 10-bit resolution! 0-511 for one direction of the motor and 512-1023 for the other direction!!! Same double resolution is used for motors 3,4 (9-bit)!


--------------------------------------------------------------------------------

Here is a schematic on how to do wirings for two RN-VN2 controllers to support 4 motors in the future... Only the first header in used for now.




--------------------------------------------------------------------------------
FIRMWARE 1.0

This is the first official release v1.0. It replaces all the previous beta versions!
For this reason I included the code for the two motion styles (Joyrider & SimforceGT) in it, and made it selectable between them with a jumper.





But his isn't the only feature. I also decided to give to the users the ability to change the servo motor KP proportiality values thru simple terminal connection:




Anyway you can read all about it in the manual I made for it:




And of course the firmware that cames in four files, each one for the crystal speed you are using:





I connected a simple pot on directly on the motor axis and had enough precision on positioning without much ringing. So using multiturn pots is not always necessary.
You can connect two dual h-bridge motor controllers on it and control four motors but with a small restriction. The last two motor channels will run on 8bit PWM. This is a restriction of the Atmega8535, as it has only one 16bit timer that is shared on the channels for the two first motors. Anyway 8bit PWM isn’t that bad and can be used in heave or rotation that precision isn’t so critical.


Some description of the features of that Firmware v1.0 has:

-It uses only the first two motors for now: The pin header on the bottom (named rn-vn2) that can be connected to the JP1 header of an dual h-bridge motor controller.

-It uses only two the first two pots. Pot1 is position feedback for the motor1 and Pot2 is position feedback for the motor2.

-Don’t forget to align the position pots with the motor or the motion travel route to successfully have position feedback. ...

Miscellaneous

strange issue w/ iracing...

I just got my simxperience stage 1 (diy kit) setup and when it works, its awesome! But we can't seem to figure out why I have such reliability problems with my motion while running iracing.

Unless I have a 'access to port 3, 4, &5 denied' error, I can get on LFS every time, no problem. Iracing on the other hand is realistically about one time out of twenty, and if I do have motion, then I change from say a practice session to a qualifying, or race session, no motion. I have yet to get motion two sessions in a row.

Fresh (legit) windows 7pro install and everything, still the same results... If I do get motion, then its constant until I quit that session.

Pc specs:
Amd phenom 2 dual core 555 (3.2g)
4 gig ddr3 ram
Gigibit motherboard designed for this cpu (can't remember the p/n)
Msi 6950 2gb twin frozer video card
Logitec wireless keyboard & mouse
G27
Wireless netgear nic adapter (tried with the onboard ethernet too, same result)
Microsoft security essentials

We've tried everything that comes to mind, so please throw ideas out there if you have any... I know this isn't really x-sim software I'm runningbut thought you guys may have some good suggestions anyway.

Thanks!
