Tutorial SMC3 Arduino 3DOF Motor Driver and Windows Utilities

Can use this this code with DIY linear actuator(use slide potentiometer to feedback position)

Arduino Leonardo doesn't have Timer2, so change TCCR2B to TCCR3B in the code.

Hi, i have a problem I use Arduino uno and two Ibt-2 h bridges

A while ago I got my simulator to work perfectly, but I had problems with my computer and had to update some parts. A few days ago I assembled my new computer, installed windows, and again downloaded Simtools, the SMC3 software and the respective arduino code. With all that ready, I set the parameters and opened a game but the movement was erratic. I disconnected the levers that connect with the seat and tested the movement only of the motors, finding that the motors do not make the braking movement, only acceleration, this happens when having the axis limiter at 30%, this is how I had configured it previously And it worked perfect, these days I have been doing tests but the only way in which I get the braking movement to occur is by raising the axis limit to 100%. I will leave some pictures of my configuration, I would appreciate if someone can help me with that.

I haven't use sismtools yet, but maybe its a problem with the IBT_2, i used them but also the rsults where erratic, and i deside to mobe to sabertooth, before of that is used MMotorshield, but again the quality was verry poor. Whish you luck..

What version of Simtools are you using? - if 2.4.1 then it had issues with the serial link when released, so I had to roll back to 2.4. I although do not know if this was later fixed.

Yep, Windows 10 2004 patch + simtools 2.4.1 does this. The serial component was broken in 2.4.1 with the introduction of 32 bit support. Roll back to 2.4.0 and it will be fine.

Hi Noorbeast, thanks again for the fast reponse, the Max and Clip settings are low just in that screenshot, i have higher values in the normal configuration, sorry for post this image.
Thanks for the info of the version of Simtools i check that tonight.

Good news, the problem was resolved by installing Simtools v.2.4, thank you so much guys, in the nexts days i will post the photos of my project.
Thanks again!!!!

hello,

Thank you for the great tutorial,

i have a small issue... following your guide at the beginning i set everything to 0 and 255 then plugged power in and my motor instantly started running, im unsure as to why though,

I am using the md30c motor drivers along with @Blame73 code adjustment, Using hall effect pots: 6127V1A180L.5FS

the pot seems rather ridiculously sensitive in the center to the point where the motor controller flashes both direction Leds at the same time and the motor buzzes i cannot seem to get it shut down?

If anyone can help i'd be forever grateful!

EDIT: GOT THAT BIT WORKING!

i had similar with smc3 code. the problem is that the arduino resets when the serial port is opened and this creates a dangerous situation where the drive pins can be powered, causing the motors to rotate uncontrolled. my sim totally flipped over backwards in a blink. there is a way to prevent this, google it. or, only power motors after simtools is active, this also goes for the smc3 utility.

either that or your pots/hall are inverted. rotate your magnets 180 deg.

Hi guys, can you please direct me on how to select MODE2 on smc3 arduino code? It says to edit the code at the top but I'm not sure what I'm editing? Please help.

Thank you so much! I was scratching my head and thought it'd be more complicated. Lol

Hi Rufus.
I am using the pololu drivers and just need to know how to connect the logic 5v to this driver

Thanks

Hi. I'm using the Pololu G2 High -Power 24v21
