Tutorial SMC3 Arduino 3DOF Motor Driver and Windows Utilities

SMC3 drives only one motor, either motor 1 or motor 2 etc. You have to click with the mouse on the "Motor 2" upper left corner to drive Motor 2..

Thanks! And is it normal that once it moved the right motor, then I had to re wire the left one but after finishing this none of them move. Checked my cabling and all is well.
Or setting up the utility needs simtools and a game to be running also?

Nope, the tool doesn't need any games or simtools to run. Should simtools be running SMC3 wouldn't be able to communicate cause the port would be already used.
Why are you rewiring the motors? have you tried just re-launching the application?

Basically this was the reason, but I only had to change the power leads on Motor 2:
"

• If it is moving away turn off motor power immediately (or quickly reduce PWMmax again). In this case you need to either reverse the wires to the motor being tested –OR– reverse the +5V and GND wires to your feedback pot for the motor being tested (do not do both). Restart the test from the beginning."

My diagramm might have been bad, the two yellow bars where represented like so, I have just changed the motor 1/2 blip and hence got the same info on one screen:

As I mentioned before in other threads (and already not only one time) do not write down your issues only, please post all photos and screenshots about your hardware/software. And I mean all...The screenshot which you have posted shows motor 1 ONLY.

Sorry about this.
So the motor1/2 picture:

My motors are wiper motors from VW:


My wiring is done like so:

I run the tools from the same pc as the games.
What else would you need?
Thanks!!

The wiring "in natura" The motor is ground isolated?

Sub thread :
Using the SMC3 Util. as Hall effect Feedback pot adjustments tool .

Now open the SMC3 Util. connected to Ard. board ... then select to display the feedback signal and motor limits Only ... you will see a Green and 2 Red lines ... the green one is moving up and down when you rotate the pot manually ... align the pot Real midpoint " some pots have a midpoint click " to midpoint displayed on the screen ... OR ... 0-180 degree to the upper/lower Red motor limits .

- Repeat that for each motor ...
- Tight every thing down ready .





Thanks to my friend @cthiggin who pointed me to this Idea ...

Yes sir

Checked the coloring and it should be fine, but then again you guys understand this whole bit better than me

@Greg83 the wiring seems to be fine, of course I cannot see if all is welded correctly. BTW your wiring is really messy, please beware of mixing any colours, use blue or black for GND, red or orange for + and NEVER use same colours for different outputs. The day will come and you have to solve any issues. You will be lost mate if you will use two or 4 MMs once upon a time (30A; 60A).

PS: already only using one MM you will be lost.

HA, ha!
The wiper motor's jumping is always surprising, isn't it?!

@RacingMat lol...you encapsulated it mate.

Hello to all,
i need a little bit of your help.
Is it at all possible to run the SMC3 code with a h-bridge which is operating
the BTS7960B max 43A chip ?
And if yes, which mode i have to use ?
Mode1 or Mode2 ?
Again - thx for your help and for your
SMC3 code.

Hi @Lighthill c&p from the FAQ:

MODE1: Supports the more common H-Bridges used in the forums. This mode has a PWM output pin plus two Motor Direction output pins. Examples include the MonsterMoto shield.

MODE2: Designed for H-Bridges that require direct drive of Highside and Lowside switch inputs. In this mode one switch is driven as a direction pin and the other with the PWM output however the PWM duty needs to be inverted whenever the motor changes direction with the direction pin. (An alternate approach would be to switch the PWM between inputs as direction changes) An example H-Bridge that uses this mode is the cheap 43A IBT-2 found on ebay.

Ok, thank you for your fast reply ...
my bridges have a

PWM ENB
INA 1
INA 2

that means i need mode 1, Right ?

THX Lighthill

Your BTS7960 is a IBT-2 bridge...so what is the conclusion?

thank you Pit,
I didn't know that, of course it helps
me a lot ...

First sorry for mi english. I'm new on this forum (since 2010 on x-sim) , I will start to build a 3DOF simulator. I have a Arduino Mega R3 2560 + Monster Moto Shield, this board is compatible with the firmware of this post correctly setting the pins or have to use the UNO R3?

Thanks and soon I'll upload a post with pictures of the process.

Regards

Guy,

What I'am I doing wrong?

Motors won't even move if PWMmax setting are set to 255, but in the tutorial it says it should start to move.
