Hi Carbon Could i ask something re the PID tuning, with fabi's software i understand it takes an average off the pot values for each motor to produce the final settings. when you did it manually i assume you have to choose a motor and use that as the reference and hope the others are somewhere close to the same? as you cant obviously set an individual PID for each motor with the AMC I can add individual PID setting for each motor, but then you will get wrong movements because of some motors will be slower than others. Best is to calibrate the motors on the VFD for its electrical properties, and then find a PID setting on the AMC1280USB that satisfies most of the motors of the 6DOF. Thanks Thanos |

Each actuator, should be the same - as mine was. |

Hi Craig just a quick thank you, for the tip about using Fabis Utility to test my linear actuator, making some good progress , seems to be working ok and will gradually increase the load and motor supply to finally see how much of a bashing it can take . Cheers :-)

I am using the CV1 in my 6Dof sim but I have problems with the tracking of the oculus.. I move out of position as soon I have some 'hard' moves.. Did you have had the same issues? If so how did you resolve this.. could it be that my camera is somewhat vibrating? I have it clamped with some dampening stuff..
I now have constantly have to re-center the view sometimes 7 times a lap..
Or should I have the movements shorter over less distance... so that the oculus doesn't have time to pick it up?!
Thanks in advance..

Hi Craig , well finally got all 6 actuators up and running and in the process of running the full system under the control of Ians BFF 6DOF software , so far things are going to pland But slight hic up regarding where is the best place to Connect the Limit switches to the AMC setup ..
All My Switches are wired in series as NC and thought I could connect them to the KLM switch, But it seems that the KLM input will trigger if my Limit switches are connected ( and the system only runs when the Switches are NO ) Bugger,,,,
May I ask how you wired your safety and limit switches and what method you used to fit the limit switches these units are so powerful,l I dare not do any more testing till I have the limit switches in circuit ,, |

Just a quick video of my DIY G-seat that I built fitted to my 6DOF - This has really added to the pressure felt in extended cornering and greatly improve the realism of the simulation. Testing video done with 6DOF off.

Hi carbon ,
Great job ! Since a while I look on different forum people who builded g-seat .All feedback from these guy's are always positive saying that it's really immersive also.
I would like also to test a g-seat on my 6dof.
One question about the motors you use.What kind of motors did you use ? Did you use servo motors like the Gs4 from simexperience ?

Yes, RC servos - 17kgcm X 4 each side.

Thanks They are cheap steel gear ones around $20 each, but I had to change the design a bit to suit. The video below will explain what the original GS4 seat uses (too rich for me) - your budget your choice. |

Thanks !!
I watched this video ;-) and the reference for rc servos ;-) it's the reason why I was interested to know which one you choose .

Have now replaced temporary steel sim frame with a full carbon fibre one. Frame weighs in at just over 2Kg (excluding fiberglass seat/steering wheel/pedals). Similar parts of the old steel frame weighed 27Kg. Have also built a carbon fibre pedal set to replace old G27 pedal set (approx 1/4 of the weight of the old raw steel pedal set).   |
