Hmm, you should watch Fabians video again. It shows all the steps needed for this to work.
Try to increase the timeout on the amc1280usb LCD menu under the park motors menu.

Hi Thanos,
With increased timeout the platform stays in the desired position for the selected time. O.k. but this is not explained in the video.
My flightsim runs with sensor direction 3 (in park position, 3 sensors have low values and 3 have high values). It seems that the position evaluation function takes a mean value of the 6 sensors and this ist not correct.
Can you confirm this wrong calculation? I know it's Beta and i am trying to help to optimize this very helpful program.
Regards Rolf

Hi Rolf, I think its better to set the park position of the motors to 50% then for the calibration, then change it back to the number you need it. fabi will know better to answer you about the initial evaluation function. Thanks Thanos |

With firmware v2.1b and 4dof configuration, I try to connect with COM4 (Fabi´s Thanos Board Configurator 1.0 beta). But no update on controller config window. Anyone have an idea why or what to test? THANK YOU

Hi Guys Really need some assistance in understanding Fabis Application , im Building a 6DOF simulator using DIY linear actuators and am getting close to Live testing . My System uses 12Vdc Motors and Ballscrews , My Amc128Usb , Dimension engineering sabertooth 2x32 and Various other items.. the controller has been built and im now trying to learn to use Fabi's App for setting up the actuators , i'm pretty much comfortable with its use but need to understand a bit better how certain function work , in order to not do damage to my unit or self as it were during testing.. in the manual setup tab i can see what must be pot range values , i may have misunderstood how these values are derived , so bear with me , im assuming that the system does not know the min /max pot values or max pot range due to mechanical restriction or design , so we must have to manually enter these values but i know these must be and adc value representing 0 - 10K ohms excluding mechanical limits . i thought it would be a case of manually positioning the pots to say half the pot range value and this value = mid travel of your actuator . now my moving the actuator using the Up down buttons you would be able to read the min max values and put that info in the min max range Boxes .. so when you hit the jump to max button the actuator would move to that point and stop and vice versa for the min . likewise if i then pressed jump to mid then i'd expect the actuator and pot to be in mid position .. my problem is i only seem to hit 3.5V as max Value and down to 1.8V when measured across Pot wiper terminal and OV i thought i should get just under 5V at max and just over 0V at min to allow full mechanical travel in that range ?

You should change the "feedback limit" value to 10% or 5% (on the amc1280usb LCD menu). What is the value you have there now?
Thanks

Thanks Fabi for this great software I was trying to calculate PID of motor no. 5 I followed the instructions, however when motor no. 5 start oscillatining and I clicked on "Stop platform button" the graph in the oscilloscope does not show a clear peaks so I can calculate t1 and t1 and number of oscillations. Check attached image. Attachments:

Check attached image. Are you using the latest firmware v2.1c for this? This might not work with the latest firmware unless you use merged PID setting for all motors. Fabi tool need to be updated to be able to use individual PID for each motor. Right now it uses one PID setting for all motors. Thanks Thanos |

One thing worth mentioning
I am not sure if it is the reason.
My VFDs accept SINK signals.

Yes I am using latest firmware v2.1c
If I am not mistaken, it was also happening before I update the firmware. I will update board back with the previous firmware and double confirm.
Thanks Thanos

I updated board with firmware version 2.0 and still the same issue. Check attached images, I also took screenshot of the config screen. the platform moves correctly using Ian's BFF software, I just need to tune PID values. Attachments:

you sure you don't need to increase amplitude zoom more? look like you are not zoomed in enough.

Does the software of Fabi allows to superimpose the curves potentiometer and effects?
Where can I find Fabi's soft?
Thanks

In fact nobody uses this application?
too complicated? nobody needs to know how to use it ..
I can not do anything either ...
it's unfortunate that we can not have something reliable, simple to monitor the effects and a simple adjustment of the PID
I would love to see a tutorial from someone who shows how he adjusts his PId with this application.
