Finally a video with the AMC controller and BFF software. Still some tuning to do, but I'm happy with how it has turn out.

Hi Carbon,
As I will be running the rift on my 6dof platform, I have the DK2 camera now on the wall but that is because it is 2Dof.. But in 6Dof I need to have the camera on the platform..
How did you isolate vibrations? And how does the motion feel, mind wise , no problems with the 'internal' sensors?

Hi Carbon, As I will be running the rift on my 6dof platform, I have the DK2 camera now on the wall but that is because it is 2Dof.. But in 6Dof I need to have the camera on the platform.. How did you isolate vibrations? And how does the motion feel, mind wise , no problems with the 'internal' sensors? This is not my first motion sim, so I am aware of the issues in mounting the DK2 camera. My current Rig was designed from the beginning to hold a VR camera, therefore I have a rigid structure and a low center of gravity to minimise any flex (low frequency vibrations) and chosen foam sheet which surrounds the camera to minimise high frequency vibrations. Works well for me, no problems with 'internal' sensors.

Hi Carbon,
I am finishing up my build but my friend would also like a 6 DOF but has problems getting enough power (he is currently renting as he just moved to this state). If you don't mind sharing do you have a build guide (motor, dimension...etc).
Thanks in advance.

No real guide/dimensions, as most of the design work was done with hand sketches, just don't have the inclination/spare time to do more, but there is a thread with pictures of the build as it progressed and some basic information on another Simulator related site. Don't know if it would be right to link it here? Links OK thanks Thanos, link

I read most of it and its very impressive. Just a little bit out of my league. I have built a few CNC machines (plasma and mill) but still learn how to work with carbon fiber.

nice build. i have read though it at least twice. are you still using 2 of the h bridges per motor? do you feel you have enough travel distance and speed?

Yes, using 2 MM bridges per motor and the actuators are limited switched at 360mm of travel. Adequate movement and with 5400rpm rated motors and the rigs low inertia and CG - speed.

What do you think would be a realistic max weight? The reason I ask and one reason I went with AC was my very limited understanding that AC would handle a greater load capacity.

Hi all,
New to the forum, just wondering what a setup like this would cost hardware wise?

Don't really know, but in testing I moved 70 kg vertically with one actuator, which was adequate for my design- I also fitted gas struts (although it will run fine without them) which offset around 10KG each (3 fitted) to reduce the load on the motors and extend their life. AC was never really a choice for me, just don't have the space, budget, or available mains power for a big AC system.

do you have the dimensions for your rig? how many degrees side to side and front to rear is it capable of?

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
