Question My 3dof motion simulator

When plugged in the computer will assign com ports to each of the Arduinos, and you assign those comports in the SimTools Interface Settings, which is covered in the manual.

I expect the Interface Settings will be the same for other SMC3 code:

[A<Axis1a>][B<Axis2a>]

Set for 10bit binary output

Baud rate 500000 , N , 8 , 1 (10ms delay)

You have 2 Arduinos so they both can't be com port 4.

Is everything configured and does everything work in the SMC3 utility as expected, as that has to be sorted first, before getting to SimTools?

Click on the Windows icon on your computer and type Device Manager, open it, then go to Ports, your Arduino's should be listed there, along with their port numbers.

The Arduino IDE and SimTools both need to be configured with the correct com port.

See the first 2 posts for the original SMC3 code to understand the basics of how to set it up and what each of the options does: https://www.xsimulator.net/communit...3dof-motor-driver-and-windows-utilities.4957/

Probably best to post pictures of all of your settings. I am away for work over the next couple of days but others can have a look and make suggestions.

SMC3 settings should be fully sorted and working as expected before moving on to SimTools configuration. You can't run SMC3 and SimTools at the same time, it will cause a port conflict.

From the guide:

1. Set Clip to 255 (you need to do this first) and Max Limit to 255 (This will give you plenty of margin if something goes wrong while setting up)
2. Turn on the power to your motors – nothing should move at this stage!
3. Set Kp to about 400
4. 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.
5. Do the above for each motor

I suggested going through the steps as the Max Limit is not assigned in the settings already posted, and it should be.

Shutting down motors tends to suggest they are moving out of range.

What type of motors are you using, are they wiper motors and if so are they ground isolated?
