Question DOF-Reality H3 Stuttering

Can you please post pictures of all of your SMC3 settings.

Please post a picture of your SMC3 setting running Sine test.

When following the SMC3 setup instructions at what PWMmax value (Step 9) does the rig start to move: https://www.xsimulator.net/communit...3dof-motor-driver-and-windows-utilities.4957/

1. Disconnect the motor power supply
2. Make sure Simtools is not running – we’re not ready for that yet!
3. Wire up the Arduino (with SMC3 installed) to your H-Bridges and connect to your computer via USB
4. Run the Windows SMC3 Utility software and make sure it communicates with the Arduino (There is no need to set baud rates, they are not configurable)
5. Set the Kp, Ki, Kd, PWMmin, PWMmax, PWMrev to 0 for ALL motors (This will make sure the motors don’t move)
6. Set Clip to 255 (you need to do this first) and Limit to 255 (This will give you plenty of margin if something goes wrong while setting up)
7. Turn on the power to your motors – nothing should move at this stage!
8. Set Kp to about 400
9. Now slowly, increase PWMmax… at some point the motor should start to move. When it does check the “Green” feedback line is moving toward the “Blue” target position.
   • If it is then that motor and feedback is wired correctly - proceed to test other motors.
   • If it is moving away turn off motor power immediately (or quickly reduce PWMmax again). In this case you need to either reverse the wires to the motor being tested –OR– reverse the +5V and GND wires to your feedback pot for the motor being tested (do not do both). Restart the test from the beginning.
10. Do the above for each motor

Try kp at 400, pwmmax and pwmrev at 100 then run Sine.

Can you please post a picture of SMC# running Sine with those settings.

Try kp at 400, that should improve tracking, but I am just guessing, as the whole point of the SMC3 utility and live interface is to allow for tuning settings specifically for your hardware.
