Tutorial SMC3 Arduino 3DOF Motor Driver and Windows Utilities

Good pickup @ericRacer, someone told me about that a while back and I forgot all about it. I need to dig the source files out and post an update.

If anyone wants the fix in a hurry just make the changes as per eric's screenshot above.
If you don't make the change then all motors will use the Motor 1 "max limit" setup using SMC3 Utils.

the IBT cards do not work anyone has ever used this?It must be programmed with a separate program, or just connect it as the IBT?

Yes these work, I'm pretty sure there has been a wiring diagram or pinout posted earlier in the thread.

I use it for 2 years now and it works very well ! (IBT-2)

Hi there! Thanks a lot for your great work with this code and tool!

And a question, is the us-time format problem solved yet?

Hi, I believe you are referring to an issue that was actually with Simtools software not SMC3.

I am not sure if the latest version fixed it or not, maybe someone else can confirm?

Thanks noorbeast! Helped me a lot!

hi, i just ordered all the parts necessary to build this except what potentiometer spec should i use? thanks

hi guys. i new in this sim things. and set up a sim with arduino, ibt2, wiper motor. i red this forum, very helpful. i solved many problems. but i have new problems
so, A axis1 working correct, all programs, even live for speed.
but B axis 2 not working correct!! if i turn pot manuel motor spinnig always...
Why?
can you help me?
this is working system...

Glad you have one working, you must be pretty close although showing the working motor doesn't really help us fix the one that doesn't work....

My guess is that you need to reverse the two wires to the motor that isn't working. What does SMC3Utils show for the one that doesn't work?

thank you for repliying. i will share a video for motor which is not working. i try wires reverse than first motor is not working too. pot working i know. all the wiring i checked many times. both of ibt2 correct if it is single. SMC3Utils show if it pass second motor, sometimes move a little bit, and wait and then turnig "off". i try different methot today. thank you again...

thank you... i changed all wiring and it works



but now i have another problem i think each motor is not working synchronize...
this is tomorrow's problem...

I have noted a problem with smc3util and I need to know if someone has encountered it. I've the SMC3 on an Arduino board, controlling an high power H-Bridge in Mode1. After tuning the right motor direction, the potenziometer, the pwmMax, obtaining the motor movement on the center position, I go in the Sine moving mode and the motor seems to move normally, but when I go to another type of moving(Manual, Motion, or any other) often the H-Bridge it's broken, or the power supply fuse blows. I think that could be a bug in the procedure that non stops the motor first of sending the new movement data, and probably the directions pins can be both active, generating a fault condition. But the source of smc3util is non open and I cannot view if my supposition can be true. Please can you let me know if you never had similar problems? It's possible to have the smc3util source code? Thanks

All motor motion is driven by the SMC3 code on the arduino. SMC3Utils simply sends position and setup commands. The motors are not "stopped" before new position data is supplied. The arduino SMC3 uses the position commands from Simtools or SMC3Utils as the input to a closed loop PID control loop that then calculates an output drive for the motor to "try" and move the motor to the required position. Tuning the PID parameters will have a large effect on how well the movement tracks the input as well as how much current is required to make these movements. If it is insufficient the motors won't track well, if it is overdone you may overload the drivers/power supply/motors.

It is most likely the sine wave motion is relatively easy on the motors as there is no rapid movement or direction changes, others are harsher. This is why the different modes are supplied so you can test and tune up so it works in all situations. The rapid changes in position/direction are probably causing too much current in your particular setup... try reducing PWMmax.

Does not sound like a SMC3util issue, if you really want help, recommend you start a project thread explaining what you have built and the settings that you have used.

Подскажите обязательно использовать плату Ардуино УНО Р3 Для варианта моде 2 ?
--------------------------------------------------------------------------------------------------------------------
Prompt payment is required to use the Arduino UNO R3 For the option mode 2 ?

No payment required. Download the code from the first post, edit the line at the top of the code to be

#define MODE2

instead of #define MODE1

and upload to arduino.

Hi there,

I'm George from Hungary.
I just strated to build my sim. I already have arduino uno board:

http://eud.dx.com/product/high-qual...-1602-keypad-shield-kit-for-arduino-844379471

and the motor module as well:

http://eud.dx.com/product/30a-high-...dule-full-bridge-driver-for-arduino-844418842

Could you help me which wiring and code can I use finally? I have 2x BMW wiper motors.

I've seen different wirings and codes here, I'm not sure now which one the best working?

Thanx,
George, Hungary
