My 6 DOF with ODrive

Maybe some pictures of the finished rig and you can always use LFS for testing.

Hi,

How can I test without the licence?

I don't really get the system of SimTools.

thanks

cheers

Thanks for the reply, I will ask for the licence later on.

Hi guys, it's me again, Ive almost finished my build now, but I'm a bit stuck on the software. Maybe you can help? How do I know what axis is what axis in real life in FlyPT? What happens when 1 axis starts moving randomly, What do we have to do ther

the axis refers to motors and the DOF refers to force in axis assignments

just in case you didn't know the only game that can be played on a demo licence is LFS

I mean, there are 6 actuators, how do I know what actuator is the first, the second, …?

they are defined in the interface ouput settings should be something like [A<Axis1a>][B<Axis2a>][A<Axis3a>][B<Axis4a>][A<Axis5a>][B<Axis6a>]

Yes but how do I know in the hardware what actuator is what axis? In FlyPT the image doe'snt show what the first and send one and so on is.

Cheers

im not entirely sure i dont use FlyPT what is it you are trying to achieve? i had a quick read and says "You can mix anything you want in each axis output or apply the Simtools filters.
But Axis1a will always be looked by the interface as sway." https://www.xsimulator.net/communit...face-for-linear-and-rotating-actuators.12859/

So, FlyPT is a program for 6DOF machines that you have to connect to Simtools. The connection works, and there are values to output to the actuators, but it doesn't say what actuator is actuator one and so on.

Also I cant get my game, live for speed, to comunicate with Simtools, maybe you can help me out with that.

can you upload some screen shots of your simtools settings?

Its now 3:16 in the morning so I will go to bed now, I can upload them in 7 hours or so. I don't know if you are able to answer then?

Cheers

Not sure might not be around then but will be at some point in the day to give it a look
Just post it when you get around to it and at least then someone else may be available to give you some pointers

all the best cheers

Hi,

Actuator 1 is the first one on the front right and they increase in the clock direction.
Last one, number 6, is the first in the front left of the rig.



So <Axis1a> is actuator 1 and so on...
Just send that data to the correct actuator port with the correct config.

In the last version, you don't need simtools to test LFS.
Just select LFS in the direct input.

For LFS to send data, first make some laps in LFS.
It generates a cfg.txt file inside LFS instalation folder.
You have to edit to output the telemetry.
Open in notepad and search for outsim.
Replace values with:

Code:

OutSim Mode 2
OutSim Delay 1
OutSim IP 127.0.0.1
OutSim Port 4123
OutSim ID 1
OutGauge Mode 2
OutGauge Delay 1
OutGauge IP 127.0.0.1
OutGauge Port 4124
OutGauge ID 1

Now run LFS again and try to connect with The FlyPT Interface directly.

Need any help just call me with @pmvcda

@pmvcda

I have a few questions:
1) The position command that I send with simtools are from the form: "p 0 <Axis1a><13>". Can I also do this with your program?
2) When my actuators are in the minimum position I want the position to be zero instead of being in the middle position when being zero, is this possible?
3) I'm not getting data from LFS, what could be the case?

Cheers

1) Yes
2) No, sorry
3) Did you make a complete lap before changing the cfg file? Also try to disable the firewall.

Sorry, fast response in a phone...

For number 2) , the interface sends to the rig a value between 0 and the number of bits selected.
So middle is half the value, while lowest position is zero.
What we see in the interface is different. Middle is shown as zero, but not zero in the bit output...

bit confusing...
