Tutorial SMC3 Arduino 3DOF Motor Driver and Windows Utilities

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?

great thanks ! sorry for these many questions but i just started ant its my learning phase :-D

Hi to all!

I finish my 2 dof some weeks ago. I am using SMC3 with Sabertooth 2x60 and I have problems. I go with the sim 5 laps without problem but sometimes the motors want to be crazy. They start to tremble or directly they off. I need restart SCM3 and I touch parameters but I don't To get A movement without problems. If I down parameters un tunning center, I dont have the problem, but I dont have movemets. I need help. I dont understound why is the problem. I would like have help of the profesionals of here

are you getting interference on the signal / pot line ?

Is the wire shielded and grounded ?

Maybe it is not the solution but when you finish to config the smc3 you need to close the software, and not still running when you have the sim and the software of simtools

in my case i can not running the smc3 and the sim at the same time.

good work btw.

Hello friend, I am speaking to you from Argentina .... note that surely you must have problems with the potentiometers you have to check if the potentiometers are well coupled with the layered motors that are knitted ... note that in the SMC3 they ballan the most together possible the green and blue lines of each potentiometer.

no have ground cable. is a sensor hall. Interferences?? mmm yes.... sometimes when the motors are stopped i fell a little movement. The sensor hall is conected with utp cable with rj45. Is posible it was the problem??

[QUOTE = "moaale, post: 220472, miembro: 5397"] Hola amigo, te hablo desde Argentina .... nota que seguramente tienes problemas con los potenciómetros tienes que comprobar si los potenciómetros están bien acoplados los motores estratificados que se tejen ... nótese que en el SMC3 se equilibran lo más posible las líneas verde y azul de cada potenciómetro.

ok i go to see that. I think the smc3 have a good movement with the lines

Esta es la sala de sensores con cable utp y rj45

I have sabertooth 2x32

You have to ground port 8 on the ardunio to get them into 115 000 baud rate or they will go crazy on you. It happens on a rare occasion in 115 to. The cannot handle any more.

Smc tool does not work in 115 so I have added a switch on mine

Might need to set the calculation rate fsid something to 3 too

I read the manual and I Saw that but I didnt take It into consideration because i have 2x60, no 2x32. Go to check. Thanks man

@Manes
I would recomend a calculation rate of 3 too.

Your KP Value is really big to. Do your geaboxes have 60:1 ?
Did you try to set PWNmin a little lower? 15 ?

I dont know the ratio of gearbox but I know the motor have 60 Nm at 42 rpm

Your SMC3 value seems off. This is what SilentShill gave me a long time ago:


This is the last time I checked mine.



Don't be afraid to put your Fpid higher. Also, put the Max Limit and the Clip Input just before the maximum position where the motor will go wrong. One tries to reverse the motor before it`s too late, and the other stop it.

I hope this helps.

Hello. I'm afraid you should use a stereo shielded cable such as a microphone or stereo headphone. and connect the braid to the negative.
the cable you use is probably not suitable or not able to shield the RF emitted by the motors.
that constant reversals emit a lot of dirt. let me know hello Marco

Thanks for the support guys. This afternoon I Will check this solutions. We keep on touch. Thanks thanks

i also had to do the same with grounding pin 8 due to the erratic shaking. and i also added a switch so i can get into the SMC3 utility
