Tutorial SMC3 Arduino 3DOF Motor Driver and Windows Utilities

@RufusDufus
The working resolution of smc3 is 1024 points, If I leave the limits to work for example with only 2.5V half the range, it stays at 512 points or within the limits is it still 1024?

Hello guys! Hi @RufusDufus

First of all thanks to the whole community! It's simply a perfect example of achieving something great through helping each other out.

I have been using SMC3 since quite a bit, and I noticed, together with a friend of mine, that it seems that Kd term is not working at all on motor2.
Anyone could confirm?

I tried to do some quick debugging of the code, and the only differences I was able to find are related to the "SetOutputsMotor1()" and "...2()" subroutines.
It seems that the following if()s are different.

...motor1...
if(PWMout1 > (PWMmax1+LiftFactor1))

...motor2...
if(PWMout2 > PWMmax2+LiftFactor2)

Could this be the case?
I corrected the parenthesis on motor2 code, but I also modified other parts during the debugging, and now it seems to work ok, but due to my other modifications I now always hardcode the parameters of motor1 also to motor2, so I am not quite 100% sure of my modifications.

I wanted just to point out my findings, so that the owner could have a look at it.

I am available for any further clarifications, ciao,

Paolo

thanks for the software, I had problems loading the code, because I programmed, MODE1 with ibt2, I did not know where I had to modify the code, finally I found this line in the skecht
// #define MODE1
#define MODE2

Hello @RufusDufus ! I am quite new to arduino coding and learning on the go. I am still trying to figure out how you got the packet data from the arduino and also how could I push commands to the arduino if I wanted to do so?

Appreciate any help on this!


Thanks

Hi guys,
I need your help!
I have build 2DOF motion rig and using this tutorial my creation is alive, BUT i have a little problem.
When I use SMC3Utils to test the rig everything is working OK, but when I try to test it with "Output testing" from Simtools as soon as I hit "Turn ON" button the center position of the motors shifts in one direction. After that it is working ok but the rig is tilted. When I turn off output testing and start SMC3Utils again the rig goes to level position.
Please give me any advice why this is happening and how to correct?
Thank you very much!

My settings are uploaded!

And this is a short video showing the problem

Smc3Utils is set in passthrogh mode just to show the problem.
in real testing simtools output is set to use serial com.

Hi,
and after 1 full day of different tries i found that the problem exist only on my laptop. I have put a brand new copy of OS changing from win7 to win10 pro and guess what - the problem still exists.
On my desktop everything works OK.
Please give me some advice because i want to use my laptop.
I have already change the OS. Install a fresh copy of arduino. fresh copy of SimTools2.2
I have no idea what to do next!
Thank you very much!

So,
After a few more hours of reading and testing, finally I found the answer...

To work properly SimTools is very important to set "System Locale" to United States.
Changing only date format to US (mm/dd/yyyy) is not enough!
Uploading some pictures how to do that for Win10

Hallo i have a big problem with smc3 and sim tools, when i try the moviment in smc3 is all ok but when i use sim tolls after one big escursion the motors stars to 360' and never stop.

I try different config but the problem is present

Hall sensors or potentiometers?

I have arduino uno R3 with spy01 the same the motor monster (HB), i use directly potentiometers. My config is standard, when i use Smc3 utils the sim is ok but when i use Sim Tools the sim do what you wont...i don't know why.

io using pots monted directly on motor, what you see are the same that i have in my sim.
io have a second spy01 to do a drift effects, is 3° motor and pot in photo not legancy to sim e spy01.
