Hi ,
Did you already try to change the sensor possition setting on am1280usb from pos135neg246 to neg246pos135 and test.Normally the behaviour should be the opposite .... or not ?
You could also test sensor pos 1-2-3-4-5-6
If you want to test the movements you could also use xsim and the 6dof plugin.When you launch the plugin you can test with sliders all mouvements.It's from far easier than using the amc buttons.

Hi mhensen Thanks for accepting suggestion as an information Tip ...I can now see your logic with your switch trigger arm . I wrongly thought it would break the switch with any over travel of the actuator lever, Nice to see that it slips once it make firm contact with the switch , so that gets rid of my concern. Keep up the great work , I eagerly read all your postings and pick up a great deal of info from all the projects here.. Have to say if English is not your first language your doing brilliant in explaining and detailing your posts, I wish I could speak a second language as well as you handle English good buddy :-) |

Hi vicpopo, I don't dear to change the sensor positions.. The directions are ok .. just the movement itself wasn't smooth, but now I am installing my 12 switches first and the master kill switch. Then I can start it up on the 2 main lines and hopefully the configuration is better and the movement will smooth out.. I never used/installed x-sim.. so I will have to dive into that.. I just used simtools for the 2Dof.. But I bought myself a BFF license and it supports the games I wanted it to be supported for racing.. But I will look into that too. Now I use the config tool to move the platform, that should be the same I guess?! |

I didn't remember all things because my 6dof finished from,a while ;-)
I didn't remember if with fabi config tool you can move all axes but with xsim I'm sure .Just to fil full all parameters in the plugin but you don't care about this step because it's just to use sliders for moving the plateform.
My thought about to,change the sensors postion on amc was to check if you have the jitter at the oppossite movement or not.If you have jitter always when the plateform goes down it's maybe a inverter setup .
I remember that I was having jitter and the problem was coming from the sensor position setup and the physical sensor setup ( positionning the sensor angle ).

I have just finished adding the 12 stop switches.. also did all motors with autotune ON DELTA configuration.
Tested all the switched and it works like a charme, btw movement was smooth both ways and getting back to center was good and smooth too! no jittering thus far.
I must say that the motors sounded better and are more responsive on the lower frequencies, but this could be just me.. but it sounded better and stronger,,
I even stood on one lever and have it slowly moving both ays .. No problems and no jittering!!..
If it still will not run as wanted, I will do the sensor direction change!!
So I have good faith for the weekend! I will surely try x-sim, just need to have a look at it as I've never had it installed.. With rhe config tool I can change the individual motor by setting values directly. but it's labour intensive. Or I am doing it wrong?!
vicpopo : as an experienced 6dof owner, what are the most common things that would fail, do you have a check list/routine or something like that?
It is a really powerful machine, so any minor issue could result in tears or worse!
Yep, I am very eager to get it up and running, but I don't want to miss a single step, especially not in safety! So any tips are again welcome!!

sounds good michael. would love to know what you did different to me to have no jitter!
yes the offline 6dof xsim plugin works well for testing axis with sliders. nothing to really set up just install and go.
the download is in the dropbox folder.

Put in your AMC 5% of offline and online speed. Test the combined movements (for ex. heave- pitch- roll- surge-) in order to be sure that you don't have any mechanical collisions.
Your platform will have a different behavior (limitations) with thanos 6dof plugin (x-sim) which is using a 3d model, and Ian BFF software.
I would recommend doing your first tests with one hand on your mouse and another on your kill switch.
Cheers and have fun!

Hi mhensen ,
You are on the right way building your 6dof.You go step by step and go forward carefully.I don't have any check list .I did some design faults causing me some mechanical troubles but your design is ok.
If you play full speed all stuff has to be well and firm screwed , bolt.The worst thing could happen is a switch off power during game , I don't know with the load where the plateform would stop !
I never want because of the higher cost put brakes on motors on my 6dof , the kill switch is a pretty good security.You have limit switch on your 6dof , wouldn't be helpfull instead that the arm could make full turn without problem ( just a question ) .
Or did your worm gear non reversible when the load push on it .

Hi guy's ,
If you want to use xsim just a tip not to forget to do before using it .Watch the thread from hexpod in motion software setup section .

Haven't done the full load testing yet.. so perhaps the jitter comes then! All I can think of that is different between yours and mine is that I have installed netfilters but I don't think that this would be the real difference.. |

Or did your worm gear non reversible when the load push on it . Thanks! The limit switches are there because of some faults in the design, that prevents me to do a full rotation of the lever.. This could be resolves by putting on longer rods between the upper platform and the lever, but I guessed that by having all limitswitches installed I would be in clear, and I do like the low position it can stand in. At this moment the rods are at the shortest position, so I have around 75mm room on each rod to play with, but this is not enough to let it do a full rotation. Also the bracing is in the path of the lever.. This is why I have all limits installed!
Although this limits me in the freedom of movement, I think this is not a real problem as I will be running with the Oculus, so no screens on board.. This calls for smaller but perhaps shaper movement to trick the mind, I think the combination of oculus and small profound movement is enough to get the max out of immersion ..
I have installed all I could think of, Netfilters, shielded cables, 12 limit switches, one kill switch, break resistors, the whole lot.. The seatbelts are due to arrive, but no helmet, that would be overkill.. So I cannot think of anymore I can do :-)
With a power failure it could stop in a awkward position but the gearbox can hold it in the position it failed.. So it doesn't sink in. But now it all comes down to testing and tuning.. But that will be the fun part..
I even did some measurements with a scale, by detaching the rod and set it pushing on the scale on the same height as the lever would be.. I think I am ok with the values I saw.. With the full platform on in the mid position I had around 20KG on the sides and 60KG on the front. So I think that when I am in the seat the load is spread equally, more on the sides and probably releaves the front a bit.
This evening will hopefully be a new milestone in the complete project!

Thanks, I will start of slow, I did run the BFF software while the platform had no rig on, and I noticed that it is completely different indeed.. And I will gradually increase the speeds from the point it all is stable and within it's limits.. |

only thing left is simvibe  i been running that on my static rig and it is indeed great as steve said. When you have time would you mind uploading a pic of the wiring in your cabinet? did you keep all the cables separated without cross over etc? im about to re-wire mine, im not sure im worrying to much about certain things. also with the net filters, did these go in between power and VFD to filter mains to VFD? were they expensive? thanks and look forward to seeing some vids with things moving! |

Simvibe I have.. single buttkicker... I will make pictures tonight, but the tidiness I had is gone.. with all the switches in place. The only thing I really did was have the shielded cable that goes to O en L go to the back of the cabinet as soon as possible, right through the panel I have, like yours, the rest is in front.
But I have to see how all works if all 6 are powered! Perhaps I am getting more noise too!
But these are my netfilters. Hitachi EMC C1 netfilter Type: FPF-9120-14 tbv WJ200-007SF en NES1-007SBE they costed 35 Euro a piece, but I think yours will be little bit more expensive..yours should be bigger. But if you want to test if the netfilter would fix, I believe you can do that by getting a fresh 220 line from a separate group at your main break..
That fresh line should then be free of noise from the VFD and you can connect the 24volt adapter from that one, but perhaps this is all nonsens and is the netfilter overkill as I don't really see them in other configurations..
Only noticed that my kill switch is of the wrong type.. it is normally closed..:-( but I have a turnswitch I will install for now.. ) but need to get a mushroom switch that is NO en goes to NC when pressed !!

One key point for the immersion is the latency for the motion .
So reduce as possible the ramp up and ramp down .Personnaly I have 0,1 s and it's ok.With zero I got inverter failures because I over come the max available current ( which is setup as its highest value obviously ;-) )
My output gearbox speed is 11 rpm and that enough beeing in the motion.To increase the feeling for real G force I maybe have to turn faster but my motors are not so powerfull enough.
There are ac induction motors 0,25 kW each.
But for sure you need to be as best as possible fasten to the seat .I have a 5 points harness and it's a must have for racing car simulation.3 points harness is not enough to be secured in the seat .You can also have a better feeling when extremly secured in the the seat , like the real life driving a racing car.Impossible to breath when the car is'stoped in the pit ;-)
