Hallo All I have started a 6dof project as many of you here. Will be adding my progress step by step. Recieved Thanos controller with extension board Have ordered 6 Motors with wormgearbox( N2=18RPM, I=1:80) and VFDs(Schneider ATV12HU15M2) which are on its way Parallely started to construct a 3d model of the Platform and trying to source rodends with misallignment spacers. Playing with excel Stewart platform simulator that I got from Youtube from 1982Danny( www.youtube.com/watch?v=1jrP3_1ML9M) for dimensioning all the mechanical elements. My goal is to get as much movement in all the axis as possible( max 30 degrees bank and pitch angle of the platform is what I am trying for. Hope I get it!!) Trying to mix Markus's and Fabi's Platform design ideas for CG to be at the chest level Suggestions, advices and critisism is welcome from the all the members Will post some screenshots and pictures as I progress

Distance between center of the upper platform to the motor shaft. Should it be more ?? It depends on the connecting rod length. But what would be the normal distance between motors?? Thanks!

Wow that excel simulator is great! wish id know about that when i started my build.
Size of upper platform and rod length will dictate motor spacing. Does the spread sheet not help with this?

It helps little bit. But the unit of measurement is not clear. For angles it is degrees but for other numbers, its confusing. If it is in inches the servo arm length is 25 which is way too high.
If it is in mm, one has to scale up the simulator to real life one, but then I get axis errors when changing the position
Otherwise, its a great tool.

Small progress during the weekend.. theoritically found out the positions and angles of the motors for the size of the platform I want... hope it is correct, physical build will verify it anyhow... It takes much more time..gathering tools required day by day waiting for the salary!!

Looks good, look forward to seeing more,
you can be sure you will have plenty of tools to do most projects by the time you finish this build!

Hi Guys have wired a first setup.. to test the data flow from FSX to the motor When I fire up the BFF driver it says, it is driving and the Thanos board says Motors online and receiving data .. unfortunately the motor is not rotating..!! will attach photos, please let me know the wiring to VFD is OK?? VFD: Schneider ATV12HU15M2

With online access making it so easy to get hold of your project files, there’s no excuse for not being able to keep everything up to date in real-time. Your team members can complete their timesheets, update their tasks and record their status as they go. If they are using the project management software as their main interface for the working day, there’s no issue with going into another application to submit documentation or update issues.
