Tutorial SMC3 Arduino 3DOF Motor Driver and Windows Utilities

There I have been testing different configurations in the 1 and 2 interface and I could find the configuration that I think goes when I move arises in output testing the two forward motors are lowered when I brake and the rear motors are raised and when I move the motors 2 and 4 on the side sway Right they get up and those of the left 1 and 3 go down, the only thing I have to do is change the C and D of interface2, I was put on Aaxis1 Baxis2 Caxis3 Daxis4 and those of interface2 had no movement ... and now the axis1 and axis3 with A and axis2 and axis4 with B in conclusion, the configuration was like this Aaxis1 Baxis2 Aaxis3 Baxis4.

Sir, I ask you a question. I plan to buy another 12v 30a switching source for the other 2 motors, but the question is the source that I have is the bank for the 4 motors.?

if you were wondering if that source supports all 4 engines ..... thanks. the ideal would be a source for two engines.

Hello everyone!

I'm new here and I want you ask all of you about SimTools game manager->SimTools game engine ->SMC3 utility connection problem. If it's wrong place to do so please redirect me to suitable forum place for it. But:

My connection built is:
PC master: SimTools game manager & SimTools game engine

<->UDP connection

PC slave: SMC3 utility and Arduino UNO with SM3 in it

I've managed to send data and read them in SM3 utilty with Output Testing for all of 3 motors but when I hit a run in Life for Speed there is no output to do SM3 utility on PC slave. Game is patched and Game manager is connected to Game engine. I see prompt "game running" in Game manager and in Game engine. I suppose there is a problem with my axis assingment. Here's some screenshots from my setups

I'm after only one day of setting this up so it can be totally bullshit .
At current state I'm in design process of building my 3DOF motion platform. I'm planning to put 12V or 24V wiper motors to simulate accelerate in a car and feel of traction loss (I supposed that is Yaw DOF(?))

Hi Peter_the _machinist,
Have you followed the general guide (in FAQ) in using the simtools setup? That guide helped me alot.
Running the game in output testing in the virtual mode shows also if it is patched correctly and values are being spat out.
I have a 2DOF racing sim and i use surge and sway rather than pitch and roll as you get more feeling. Pitch and roll is good for track surfaces and flight sims but you can barely feel it in racing sims

Dear noorbeast, thank you for your reply.

I need to disagree with you, about port conflict because I did manage run SMC3 utility and simtools at the same time, but as I said not on one PC. I'm sending data via UDP to my second PC and everything working great on output testing but the problem is that I've run LFS one time patched it then everythins seems to be set up and connected but I cannot get output data when I play the game. In fact I don't know how to use axis assignments. I don't exacly know what % value mean there. I saw that some of users use same type of DOF for different axis, but dunno what for. I'm basing on racingcube fasetech early(stage of kickstarter) construction, maybe it will help to understand what I'm trying to do. Here's screenshot from my arduino-connected PC with SMC3 utility running.

Dear Chris Chopping, thank you for your reply.

I think you are right about forces to get from game. I simulating G forces of a car by pitch and roll of motion platform but forces to get from game should be surge and sway. I will try to patch the LFS one few more times and try to get output data on virtual axis at least( I did not managed to do so yet).

Hi, I've managed to get the data to SMC3 utlity! The problem was probably that I've close the game repatched it and then run once again instead of close the game unpatched it run the game then close it and patch it. Thank you very much and till next bug!

Let me know if it works!

It work like a charm, thank you! .

I have another question. Probably to @RufusDufus if he is still here. I was wondering is there a way to set UDP output mode as a standard/automatically after utility start up. I Have small industrial computer as my SMC3 utility runner and after whole configuration proccess I would like to make it plug and play. I want to turn on the computer without screen and that's why I want it to sending data to arduino automatically.

Hi this is an amazing tutorial. I am having a problem with this though. I am making a 2dof project with 2 of the Chinese motor controllers. I have them all wired up right and I have imported the smc3 code to my Arduino. I set up the com ports in the smc3 utilities. When I put in all the settings on smc3 and turn on my motors they don't turn on no matter what. Also in the top left it will never let me turn on my motors on smc3 @noorbeast could you help at all?

I am using 2 ibt-2 h bridges and I have set it to mode 2

When I go and turn up the pwm max the motor does not move at all. Also in the top left it doesn't ever say that the motor is on
