Tutorial SMC3 Arduino 3DOF Motor Driver and Windows Utilities

Hi! I installed the pots on the motors but, now the green line has gone above the blue line. What should I dial in to fix it?

I meant the green line of feedback is above clip limit but, seems it's a POT related. I'm new to this software.

more power on the motors? What happens if you test any motions in SimTools?

It was the pot position related to motor, so the clip limit relates to the movement of the feedback(green line), I'm stupid, didn't notice it. Problem fixed, just need to adjust the pot position. The motors are working with feedback

Awesome,
hope you keep modify the recovery power, simtools's smooth function doesn't work at recovery after sway.

hello DSSxSIM!

you've already built your simpit and testing Simtools ?
please share some pictures of your building we'd be delighted to see it

yours

Hi there,
I bought a ready-done set on Taoboo(like eBay in China),
I'm trying to make one by my own, so I'm studying on x-sim and here,
and found out the one I brought was built base on SMC3,

My idea is making a motion platform that I can simpley put a none motion racing seat on it,
still learning on which firmware, what motor should I use.

I tried both softwares you're talking about: Simtools is the simpliest to use and very good with the biggest number of updated plugins!

Never heard about "ready-done set"
Could you please share the URL link?

He means that he bought a ready to use simulator.

Hello everyone,
So I'm new here, and I have a little trouble setting my prototype, my first two POTS are interfering somehow... I'm using 7k POTS, maybe they are too small, I've readed that @rafael_design had this issue and wondering if it realy helps to get bigger POTS becouse the interference isn't gone anywhere...
And by the way @RufusDufus you are genius!!! Your software is amazing! It made my life much easier!! Thank you so much!!!
Thanks in advance

It is unlikely the value of the POTs is the problem. Lower values are more immune to noise but will draw more current - not really an issue compared to what the motors draw.

Post a video so we can see what the problem is.

Thank you for quick response! that's amazing!

So as you can see in the video, either first or second POT i adjust it reacts in SMC3 for both motors, either it's first or second. Third motor works perfectly. I dont know maybe i'm missing something, and they have to react like that, (i know that they are bonded) but when I run both motors they starts to act not like they schould. By the way I just bought new biger POTS and nothig different happened.

This is what happends bet i run both of them, in SMC there is activated motor 2, but when I'm adjusting the first one, they both move....

Sounds like the POTs are connected to the wrong motors?

I just wanted to say thanks for the great tutorial and utilities program ,,, Cheers @RufusDufus

Ok, I changed the POTS to differnet motors and nothing different happend, they still are acting strangely... It looks like they are bonded somehow. For exaple I turn on both motors (in picture they are off) and activate the first motor like in the picture below, but my both motors are moving, when they reaches the POT limits they starts to make noises....

Found the problem!!! analog pins on arduino vas conected by a mistake, i removed that snot between A0 and A1 and everything is working now wery well!

This is great! Thank you for sharing!

Hi,

I've been trying to tune the PID loop running on SMC3, and I can't seem to get the Kd value to do anything...

​

On the left I have Kd set to a low value, and I'm getting overshoot in the step response of my sim. This is normal.
On the right though, I have Kd set to it's maximum value, and I'm still not getting any damping of the motion in response to the squarewave. I can still change Ki, and Kp, and they behave normally. (Kp makes the sim move more sharply, Ki mostly just causes oscillations because there's barely any steady state error). I've tried changing it on both motors. Has anyone else had any problems with this? I'm using V0.7.

@Tim McGuire as far as I can see your screen shots show me nothing special, the little overshoot is given by the hard movements of the SCM3 utility and later under "real conditions" hardly remarkable in the game.
