Hello hexpod
thanks for you answer. Yes your right I don't use servo motors,I will disable it when I am at home from work and test it again. Do you think the rest of the config looks right?

i found some time to test it amc runs on version rev2a and i deactivated clearpath motor installed hexpod iam happy for now it looks pretty good i hope  when i activate the hardware link the motors short move down and up this video
I have had run a complete 6dof test
and deactivated the thanos display jumper 4
the last test looks good (heave)
on the other tests, the motors didnt move so much maybe a bit to late? it looks different to the computer montior
is this ok or is something else wrong?
Thanks for your help

I still had to see how the test looks like with the platform mounted
I did the test twice without changing anything in the second video, the two left hand motors are moving very much. just before the heave test. But why? Everything looks good in the first test run. In the second, the engines suddenly move too much. I do not want to sit on the sim if that happens in game 
First test
Second test

For correcting the geometry, we have several options. I want you to try the following: 1.) tune manually the sensors orientation so they are in a horizontal position while the AMC signal gives 50 percent. 2.) open the heXpod software and put temporarily the "heave offset" value at 0 3.) mesure and report all distances of your design in the GUI 4.) tune manually the "heave offset" (in your case somewhere between -90mm and -120mm) 5.) redo the 6dof test |

How did you cabled it?
Is the motor 1 - bottom right
Motor 2 - bottom left?

Good morning Iam very happy to see the Plattform is moving
On Monday I thought the Plattform never will move but today it looks good. 
Today it is Halloween 🦇 so I can't test the Plattform but I made a picture of the motor setup

you have to swap
motor 4 -> motor 1 motor 5 -> motor 2
motor 6 -> motor 3
motor 1 -> motor 4
motor 2 -> motor 5
motor 3 -> motor 6

If you don't plan to use BFF 6dof software, I think, you can keep your motor numbering and adapt the heXpod software so the motor 1 in the 3d model corespond to your hardware.
Pay attention to the color of the cubes -- red = motor1 than clockwise.
(- 30 deg. Outward)
Keep in mind that that is not the standard numbering.
On the other hand, if you want to respect the BFF standard you have to go this way:
and rewire your motors like this:
motor 4 -> motor 1
motor 5 -> motor 2
motor 6 -> motor 3
motor 1 -> motor 4
motor 2 -> motor 5
motor 3 -> motor 6
which correspond to this: (30 deg. Inward)

short update i changed the connection to the bbf standart (thx hexpod) updated hexpod to ver. 2.3 insert all data from my sim in hexpod software the 6dof motion test looks good. the movement is the same on the 3d model this video
but when i try to move the sliders by myself the motor are sometimes moving 360 degrees is this normal? did i changed the direction to fast so the motor cant stop and just moves on?? |

Hmmm... 360 turn is bad and dangerous. 1.) select 180 deg in the AMC menu 2.) set the output field in heXpod to 360 Redo the test |

i did but it doesnt work the automatik 6dof test always looks good but when i move the slider for example -roll- from left to right after a few times the motors are running longer after every slide, an then the motors get crazy and turn 360degrees i had to remove the platform i dont want to damage the sim but thats dangerous i never will sit on this sim  shoud i maybe get some new sensors? (but usally i think they work good) maybe its the config of the amc or the inverter? |

"but when i move the slider for example -roll- from left to right after a few times the motors are running longer after every slide, an then the motors get crazy and turn 360degrees"
I don't know why your motors getting out of sync.
Insure that you have the same PID for all 6 motors.
Set you P a bit higher (increase the P until the arms starts to oscilate than reduce it a bit)
It can be that the issue is somewhere in your inverter config.
Unfortunately I am unfamiliar with inverters. I can't help in that matter.
Good luck!

UPDATE the problem maybe is the motors are breaking to bad. they running out to long and it takes to much time to change direction. the direction sensor gets out of range and the motor is turning on in direction to get position back. hmmmm now i changed the parameter dec in the inverter from 3.0 to 0.1 it seems that the motor now is not running out much and changes the direction much better. i moved the slider for about 4min from left to right an nothing happend no 360turn. i will test it with all inverters but for now it looks better. can someone tell me if this could be the problem?  |
