Hi Paiva how are your successes? I have the same sim, it is difficult to adjust

Hi valmar,
I difficulty in yaw axis, the axis roll and pitch is work nice. send me picture your simulator, to can see if I help you.

Hi! I will be grateful if you help. I'm not sure the right motor switched output to THANOS board. I'm not sure this is correct? I have everything ready mechanics electronics only need to configure correctly

hi valmar, which potentiometer you are using? It seems to me you have to review it. I use pot 360 with pulley, 20 mm on the gear unit and 54 in the pot.

Hi Paiva I'm using 6127V1A180L.5 sensor, I too use 20 mm on the gear unit and 54 in the pot. I wonder how you set up the board THANOS !

hi Thanos, you could see the question of the yaw axis to 4dof?
Thanks.
Rafael.

what is your problem ? the Yaw axis does not stop? you have already set the potentiometer on the axis and not hold it in hand ... Then I would put the minimum speed to 1 in the AMC. why you put 5 axis in AMC, you need 4 DOF. What are your settings in the drive? minimum speed, minimum basic frequency? what is the setting of the oversampling in AMC? even with a potentiometer, your yaw engine should stop. I will also be concerned, I make a 4DOF for some time motionsim.freeforums.net/thread/20/ultimate-machine-4-5dof-simulatorThanos, you told me that it was possible to rotate 360 ° non stop, what is the problem? I'm not understand his problem

I'm not understand his problem Its not really a problem, than a missing function at the moment. What I have to add is speed control with artificial PID that deals with no limits thus to be able to get beyond the 360 degrees of the sensor. I could do it sensorless but then there is no really way to tell the home position. My plan it to use normal PID with separate value than the rest of the motors for YAW on start-up / stop motion states, and then switch to the hybrid mode open-loop PID during normal play of motion simulation. Doing my best to prioritize all these requests to be implemented as soon is possible. Thanks Thanos

ok, he seems to have a different problem then is not it? On the video it seems unable to stop the motor with the potentiometer?
the potentiometer 360 ° without stops can serve as a home position can be?
usually when the potentiometer turns outside his electric plate, that's a bug, he loses the position, we must reposition the engine.
it is may be possible to correct it to serve that a potentiometer for the home position Yaw? it is an idea ...
yet it must be able to use a potentiometer of 10 rounds? it can wait while you do the function.
ok Thanks

Hi all, I did some tests for online offline switching of the feedback for Yaw so it in 4DOF it can be used to position the platform back to home position. For this to work, a 360 degrees sensor is needed without endstops. A few days ago I got some small motors with double output shafts on their 40RPM gearbox and very small current consumption. I literally can power these motors directly from USB!! So I'll be making a 4DOF model with them as it easier to work on the model and validate the firmware changes. I plan to combine the 3DOF axis in the controller instead of having to do it in software. Its not so hard and will be easier for users just to feed pitch/bank/heave/yaw information directly in the controller, less headache in the software side. I already hooked up one of the motors to axis 4 (Yaw) and did the changes for switching from positioning (offline mode) to continuous 360 degrees rotation (speed and direction control). I also implemented smooth transition algorithms for the online-offline switching that will be global (in all axis). See the video of the YAW fix I did so far. Firmware update will be released as soon I short out the algorithms and finish some more tests. www.youtube.com/watch?v=ke5-mSqJ8HQThanks Thanos

cool ! work begins again !! Good luck and thank you;) I will prepare the tests. I'm just organizing my garage to be able to test
