Tutorial SMC3 Arduino 3DOF Motor Driver and Windows Utilities

Can someone explain-me why is the motor only folowing the inpute line (Blue) in one direction, i have cheked 100 times de conections but I cant figure it out.
My conections are just like the ones in the foto .
Any clue to solve it????

i got this problem before few week, the problem was the ibr-2 (-) or (+) wire not attached correctly i mean one of them not receive power from the psu check them

Check your potentiometers wiring, as I not all potentiometer put the variation pin in the middle. I had that problem once.

Can SMC3 control brushless 36V hoverboard motors that use this kind of driver board?

Hello everybody.
I have been testing "SMC3 Utility" for a few days and I need some important answers.
I think I understand that "SMC3 Utility" was created to program the Atmega328P EEprom (Frequency ... PID ... Limits ... etc), but I didn't understand one thing: programming the Atmega328P EEprom will take effect even while using SimTools?

The following parameters are present in the "SMC3 Utility" software:

Max Limits
Clip Input

Do these parameters replace those of Simtools "Axis Limiting"?
I think I understand that Max Limits and Clip Input are like "limit switches", correct?

Or are the limit switches the ones set in "Axis Limiting"?

Hi Noorbeast, thanks for the reply.
Since I am not very familiar with this forum, I had also inserted this request for help in another section (already deleted) because I did not know which is the right place. Can I write in this section for information on SimTools software and "SMC3 Utility"?

Thank you for your support that you are giving me.
I have a very important question for my experiments:

I have to convert the PWM signal to analog (0-5 volts). To do this, I don't want to use the RC filter, but I prefer a ready integrated DAC. The question is simple: I read that SMC3 uses 10 bits [1024 passes] (see attached image), but in the SimTools manual I read that it uses 8 bits [255 passes] (see attached image). Should I use an 8-bit integrated DAC or a 10-bit integrated DAC?

Thanks for your kindness and availability

Hi All, i am unsure where i am going wrong, i am using Arduino Uno with a sparkfun monster motor driver. I have an issue with one motor not reversing, i have normal pod response, directions of movement with pods is responding as expected. If i swap motors and pod wiring the swaped motor works fine, at this moment my motor 1 will move in one direction only where motor 2 gives me normal movement up and down.. i have now replaced the MM drivers 4 times tonight i swapped the my last brand new MM driver and still motor one refuses to reverse.. i am using SMC3 version 1.. any advise.. it appears by the led’s on the MM that it is not recieving the reverse PWM signals, when moving down the dir+ led goes on and of, in the dead zone or on the boundry i can se the dir - lightly lights up when i move in the different direction the led stays off.. if i compare it with motor 2 which is working i get the impression the driver is not getting a reverse pwm.. tried all combinations with pwm max, pwm min.. so i do not know where to check next.. thank you in advance for your time.

I have not, thank you will give that a try, the previous MM did work nice both directions and then just out of the blue i had this one way issue and could not get around it.. reading the issues around MM and watching this testing video i am honestly at a point where i am looking for a alternative motor driver to run my Wiper motors.. these MM seems to unreliable by some of the reading i have done now.. is there any good alternative your would recommend for such a motor controller.. something bullet proof if it exist hahaha

Hello!!! Can you please tell me if MD13S is compatible with Cytron 13 Amp and SMC3 software? Thank you !!!

Crookedly wrote sorry !!! Is Cytron 13amp MD13S compatible with SMC3 software?
Thank you !!!

Thank you!!!

Hello,

can anyone tell me pleace what a line in the code must i change when i want to use mode 2?


// Set to MODE1 for use with a typical H-Bride that requires PWM and 1 or 2 direction inputs
// Set to MODE2 for a 43A "Chinese" IBT-2 H-Bridge from e-bay or equiv

#define MODE1

// Uncomment the following line to reverse the direction of Motor 1.

// #define REVERSE_MOTOR1

// Uncomment ONE of the following lines to enable analogue input AN5 as a scaler for the motion values.

// #define ENABLE_POT_SCALING
// #define ENABLE_NON_LINEAR_POT_SCALING


must i write #define Mode2 ??
And this there must be uncomented or ?? // #define REVERSE_MOTOR1

And when i have a linear pot i must uncoment the first of the two write?



Thank you for helping me!

Sorry for my stupid beginners question.

so i have to use SMC3 Tools to setup all parameters first ? these parameters are stored in the arduino than right ? and these parameters stay until i reopen the util again and change anything?

... so theres no configuration of kimits and speeds and angles and stuff within SimTools or FlyPT?
