Need your help with my 2DOF project

hi

I want to make a 2DOF motion simulator with two 24V DC 500W 450r/min gear motors (MY1020Z-500W24W).
First I wanted to use two SCN5 linear actuators, but over 1k€ for 2 devices is just too much and these 2 DC motors I already have.
For the movement I would use 1/4 of one round of the motor and a potentiometer for positioning.

But before I can build the simulator I need some advice from you.

1, Do you think the motor is suitable for my project ?

2, What combination of controller and driver should I use:
Velleman K8055N and Sabertooth dual 25A or two Pololu Simple High-Power Motor Controller 18v25 USB

Is the K8055N and/or the Pololu 18v25 even supported by X-Sim or does X-Sim only support the Jrk12v12 and the K8055 (without N) like many people in the community use.

Thanks for your help

Motors http://www.motiondynamics.com.au/worm-d ... orque.html
Control boards http://www.pololu.com/catalog/product/1393 one per motor, so 2 motors, 2 boards. JRK is self contained controller and h-bridge in one. Easy to set up, will run 14v at 30 amps continuous with heatsink and fan cooling.
K8055 (n) is supported by x-sim, but can be a bit slow in response time, like 50ms. Still a good board for running h-bridges.
JRK can run at 5ms, but is restricted to 13.8-14 volts.

hello bsft

I know about these worm motors and that the JRK12v12 is a good motor driver for them.

But I want to know if I could use a normal servo motor and the devices I posted.
If the similar K8055 and the Pololu Pololu Jrk 12v12 is supported by X-Sim, it would be realistic that these devices will run too, but if s.o. could give me a proof it would be nice.

In the Specs of the K8055N is written that it has a sample time of 2ms. So it wouldnt be so bad...

For more info on k8055, register on www.x-sim.de and there is some good info there.

I am not sure about what proof you need about k8055 and jrk running on x-sim.
Read the posts I suppose.

I dont think its too hard to understand what I want.

Then make it clear what you want! :freu:
Look at the threads!
There are projects and videos showing JRKS running on simulators!
JRK USO commands!
~221~~64~
~221~~a01~
~255~

K8055, log on to x-sim.de and search the threads.
Look at the threads here!
They work on x-sim , otherwise why the hell would people use them!

So you are 100% sure that the communication from x-sim to a k8055 is the same as to a k8055N and to a JRK 12v12 is the same as to a 18v25? I dont think so.

I know that this might be possible, but when I buy one of these devices and then see that they have changed the interface and x-sim doesnt support this and there is no plugin, then I am the idiot... :no:

Post the question on www.x-sim.de and ask it there.

why are there 2 communities for the same software? I want to stay here.

I dislike this as well

I agree, there is a wealth of information here, but the software, unless you are still running version 2, is on the new site.
It is not the same software, but updated with new features on x-sim 3 site.
If you want the new software to go forward , then post questions there as well.
If you are happy with the old software, then stay here.
There is information relating to K8055 and JRK that is not posted here, nor will it ever be posted here.
If its too hard for you to go to a different site for information, then so be it.
I cannot and will not help anyone whom doesn't want to look elsewhere and post elsewhere for answers.

I CANT REGISTER TO XSIM PORTAL WHY ?The password does not contain the required characters.
You have provided an invalid answer to the question. EXAMPLE PLZ?

Yes you can if you read properly:

---

Password must contain mixed case (capital and normal) letters and numbers, for example:

pASSword1

Is good.

---

No symbols allowed because the software can't handle them. For example:

pASSword1!

Is wrong!

---

The answer to the question is easy, just read it correctly!

Hint: Homepage Forum

Watch the capital H and F

---

Not that difficult right

Because the owner of this forum (x-simulator.de) and the actual programmer of the software (Sirnoname, also owner of x-SIM.de) had different opinions about the future of the website and the software they split ways.

Since x-sim.de is run by the software programmer and is the official support site that's the place to be.

Nuf said.

hello David (bsft)
i saw sometime you suggest this motor
http://www.motiondynamics.com.au/worm-d ... orque.html
to people for their project with 20 NM of turque which is enough
and 180 RPM which is much faster than ordinary wiper motors with normally 40 RPM
would you please explane for a project that using AMC 1.5 and pololu VNH2SP30
how does it work with such a motors with 180 RPM :?
thank you and regards

Hello, I do not know how to set it up on an AMC. Thanos would be the one to ask for that. Best post this question on www.x-sim.de

thank you David for quick reply
but another question,if you using the same wiring
and boards but using normal 40 RPM wipermotors
instead these fast 180 RPM motors,basicly how could it be possible to adjust them
for the same result? :?

Ok, I will give the example of the JRK here as that is all I use.
I used wipers at the beginning and then went to big worm gear motors later.
I was able to slow the motors, but not much , in the JRK utility program. Maybe slowed them to 140 rpm?
I used PID and max accel power setting to control them, They are still fast, but the settings helped.
Also I had to re-do profiles as well.
The motors respond well, they can be slow and rolly to a good profile, but with fast bumps.
I can have fierce and nasty motion on Dirt2 and 3 trailbalzer and F1, and softer motion on Race 07.
Its a matter of PID control, power control and profile writing.
Remember, that each different car and each different game will give you different motion.
You can write a one suits most profile, like I do , or write a custom profile for a particular vehicle.
Otherwise, as said for AMC board, post the question on x-sim 3 site.

ok David
thank you again and i got the point :yes: ,but i think
if u use the 180 RPM and reduce the RPM to the proper
point mechanically with another gearbox,(in my oponion around 20 to 30 )
you have much stronger torque,longer arms and easier job to setting and
mathing profiles...
