Tutorial SMC3 Arduino 3DOF Motor Driver and Windows Utilities

Thanks so much for the feedback. Did all these steps over again. all works correctly. here is pic of settings

the motors start to move at 36 pwmmax

OK Thanks i will check that out.

This is what I have. It does not mean it is the best setup, but it seemed to work.


Pierre.

Thanks so much. im doing some experimenting to see how that helps.

Hi,
Can someone explain me difference between Target sent and Target recv plot? light and dark blue?
And why for some those are equal and for some, like me, they are not?

Hello All
I'm hoping for some advice.
SMC3 ver 13.07 ( Its a DOF reality M2 that I have modified and upgraded into a 2DOF platform).
All is working, but I cannot get the SMC3 limits to change.
Example - POT feedback is - Up limit is 3.3 volts. Mid point is 2.5 v and lower is 1.8v.
It does not matter what numbers I set for Max limits and Clip input, the servos will only drive to these max and min feedback (pot) voltages. IE 3.3V Max, 1.8V Min.
I am wondering if the SMC3 loaded into the Arduino has the max limits and clip inputs locked ?

Am I correct to say that with the limits set to max, the servo should drive to virtually 0 and 5 volts of POT feedback ?

Many thanks.
Warren.

Hello Noorbeast
The control box is a DOF Reality M2
I used DOF Reality tools to do their firmware update.
Their SMC3 utils is called Ver 1.02, But it says Ver 1.01 on its screen.

Can you advise on how to adjust range for servo feedback ?
Currently the servo moves 100% + is 3.3 volts, and 100%- is 1.8 volts.
I'm looking to use a range of something like 0.5 to 4.5 volts.
Many thanks.
Warren.

I just uploaded a screen shot

Well, for anyone who may find this useful..
Dof reality's version of SMC3 has a lot of the parameters locked..
(Side note...
1.. It appears there is no easy way to backup software already loaded on an Arduino Uno R3..
2.. the DOF Reality tools will NOT reload their version of SMC3 if you load the normal version 1 - not a problem for me, but be aware... Balance function will also NOT work).
So, I compiled and loaded SMC3 VER 1 .0..... Set up parameters as I wanted, and all is good. I can now get full travel on my servos.
Best regards.
Warren.

Hi, I am working on a 2DOF and Built the control part with unoR3 and IBT-2
when trying to use SMC3 utility to find the right parameters I met the following problem: after the utility establishes connection with the Arduino board I cannot turn on any of the motors, all appear turn in off and cannot be on again!
Any suggestion?

Are your potentiometer at the middle? If not, they trigger the safety stop.

where can i find the links to order everything? or could someone help me with this becouse i want to make sure i order the correct parts

My potentiometer îs the green line

It should be in the center as your actuator is in the center and follow along. In this video, my actuator is a bit up and so is the green line.
