PT-Actuators 3DOF system?

The way I've setup my heave axis it's almost like a vibration (10% axis assignment and a very narrow range of +/- 0.5 in tuning centre). When I go over grass or bumps it feels like a vibration that is similar to a buttkicker feeling. You're right though, on a stiff rig I guess that feeling would transfer through to the seat in either configuration.

I don't own this yet, but I'm envisioning giving quite a lot of range to heave and prioritizing it over some of the other effects, because I already have other forms of motion cueing for things like suspension bumps, sustained lateral g, etc. , and because I'm a big fan of tracks with major elevation changes.

Will be interesting to see how our different priorities and philosophies are handled by the hardware!

With statements like that being made by Simtools developer will you confirm or deny that you are now involved in some way in the the distribution in the USA of those very actuators? And what is the nature of this relationship? If true I would think that would be clearly posted on this website somewhere already for full disclosure but maybe I overlooked it.

Partnership with GadgetGizmo USA

GadgetGizmo

We are excited to be partnering with GadgetGizmo, the creators of SimTools!

GadgetGizmo teams will represents PT-Actuator team to run the business at local USA,

and also cover the business in north American which not covered by PT-Actuator exclusive distributors/retailers.

We will keep you posted on upcoming simulator kits…

Today's Work Tomorrow's World!

Why?

Sadly I'm not surprised you must ask such a question. Maybe they do things differently in Greece but in this country and many others businesses usually try to practice something known as ethics.

"Equitable, fair, and just dealing with people that, although pragmatically flexible according to the situation and times, conforms to self-imposed high standards of public conduct. Once practically interchangeable with 'moral,' this term has acquired quasi-legal connotations and has moved closer to 'legitimate' following the recent (second half of the 20th century) schism between private morality and public morality."

In simple terms, yobuddy aka Dustin Arrell, has been well know on this website for being the author of Simtools motion software for many years now and not for being a supplier of any motion hardware. His authorship elevates his status so most people are naturally going to put more weight on what he states than most others. And while I'm not saying Dustin isn't being truthful when he says you can't go wrong with them, if true that he is making money from their US sales, then he would have a natural bias towards recommending them over others that are as good or even better due to profit motivation. Therefore to conform with well known ethical practices, one would publicly disclose on this website that they are also now selling these motion actuators so that people currently unaware of this can consider possible bias in their decision making. I hope that helps with your understanding.

I repeat the question. Why?

Transparently.

In any case its obvious if you go to both sites they are related to one other if someone does that. I was just surprised and disappointed to learn about the relationship in a round about way and not disclosure here but again maybe I just missed the announcement.

Four words: None Of Your Business...

@yobuddy - "And the 3 actuator MDBox controller also support vibration input (which I have been told works quite well with GameVibe)."

Any ideas on how to set this up?

I didn't ask you anything I only replied to your questions. Its clear to me now anyway just not to everyone.

Back to topic...

Not sure which member is as its from my YouTube subscriptions, but he used a smaller PT-ACTUATOR servo to add belt tensioner so cleverly!!!

> Thats not right... the Belt Tensioner is not a PT Actuator... It‘ s a Frex Actuator

Oh, my bad, I'd swear it looks like the flange 60 baby monster one here:

I notice they have a 3DOF+RTL kit on that page, and 3DOF is their marketing term for '3 leg 3dof', where 4DOF is their term for '4 leg 3dof'.

Usually when I see rtl+3dof setups, it's a 4-leg 3dof kit on top of another platform which has the rtl components.

Forgive me if this is a stupid question, but would it be viable to have 1-front-2-back 3-leg-3dof, with just the back two legs sitting on a a small RTL platform? ie the two legs are standing on a length of profile with rollers on the bottom, and that that rolls on a small platform with the rtl actuator, and the whole rig just pivots on the front 3dof actuator?

Or would that harm the front actuator?

Actually is a very good idea. The actuators are rigid and having the front actuator foot to rest on a small rotating "lazy Susan" would be fine...

Its so much easier when you have a single rotating point on front to add the TL on the back

That's exactly what I'd be after for my 3 actuator setup. I did mention to PT Actuator I would be keen on a TL frame that's designed for 3 instead of 4 actuators, and they said they could do it, but I've not seen any plans for drawings from them for it yet.

If you get any news about this keep us informed.
I have been trying it myself and tried to get some info from different sources with no luck

I really don't see how it can. Everything I've read about Gamevibe shows it as outputting the signal from a soundcard as a soundwave output, the same way that both Simhub and Simvibe do it. The soundwave is then amplified and sent to the transducers which are basically just low frequency speakers. For it to work with MDbox and the actuators, it would need to output as a data signal, not a soundwave, via the same USB port that the the MDBox is connected to. I'm not aware of it being able to do that, but would be great if it could somehow!

New MDBOXes has audio input (mono) that converts sound waves to vibrations. Very unclear how the get it tuned. No problem playing music on the actuators, harder to get lets say a RPM vibration thru gamevibe. Maybe I am doing something wrong.
