Thanks again for the links and nice clear photos.
I've read through them and I think I'll have a crack at it myself

As I understand it so far, I just need to order a single motor kit with circuit board and then fix the motor vertically behind my VKB pedals. I already use them without the "spider" feet because I mounted the central box unit on a flat plywood plate, which makes it easier to attach to my DOF h6.
So if I bought the kit, plus a cutout switch, an adjusting pot, a USB 2.0 B socket, a drive belt, and a motor cog, then I just need to source a printed large gear wheel ?
I notice you specified the middle size single stepper motor kit, I guess because it's the best torque rating for pedals ?
Is there a waiting list for single motor kits ?

DDedlike wonder is someone knows whats going on here, i made some changes to my diy rhino...

Honestly, the primary reason I went with the 03 vs the 04 motor is that the 04 was backordered when I was ready to order and I don't like waiting. My published as-built design specifies the 03 because the longer motor would not fit without some modification to the design..

The reality is that even the 03 motor is capable of providing more than enough force for my tastes.

Looking at your setup, I think the challenge will be getting the motor mounted in a way such that the output shaft is inline with where the drive gear would attach to the pedal arms.

Jehly•12/23/23, 3:03 PM

I second what @_gunzablazin said about the 03. It’s MORE than enough.

DofMan1234OP•12/23/23, 4:24 PM

Thanks for the confirmation. I'll check out the PDF drawings of each motor to see how they'd fit into my theortical layout. I think the advantage of the VKB pedals is when the spider spreaders are removed the main central box is quite small, so I should be able to raise it to the required height to line up the output pulley. Though I will be choosing the shortest motor possible to keep it as low as possible. I also use the H6 with fanatec car pedals, so I'll keep the pedal support plate at the existing height.

DofMan1234OP•12/23/23, 4:38 PM

That's good to hear

, a 12 month wait would seriously cramp my enthusiasm !
I've had DOF rigs for three years now, originally an H3 and now an H6, extensively modified.
They are great for car sims, but they have a problem with flight sims. The direct drive motors suffer from "cogging", because of the much more subtle pitch and roll movements.
The newer SFU gearboxes greatly improve the smoothness, but the jerking during what should be perfectly smooth angle changes is still an immersion breaker. They use simple 24v DC brush motors, so the default direct drive motors jerk around the commutator segments when making very (very) slow are partial revolutions.
There is a DIY solution though. A clever Guy on the Facebook DOF Builders group hit on the idea of swapping the direct drive motors for 4:1 planetary geared motors. So the motor shaft turns 4 times faster for the same degree of SFU "lift". I did the mod on my H6 and it is now beautifully smooth, even when the MsFS or xPlane autoplilot is making barely perceptible movements, (which previously jerked badly).

Here's a video of my DOF Reality H6 motion platform after being modified with Planetary Geared Motors to eliminate the jerkiness during subtle changes in pitch and roll. This is caused by "cogging", where the motor steps from one commutator segment to the next when making partial revolutions. This spoils the immersion, especially in VR, becaus...

DofMan1234OP•12/23/23, 10:21 PM

It's quite a controversial subject.
I managed to reduce it on my H3 by moving the pushrods to the innermost holes of the SFU operating levers. That reduced slightly the total angular range of pitch and roll, but it also effectively "down-geared" the movement, by altering the lever's pivot distance.
When I upgraded to the H6, that mod was no longer practical, because the principle is totally different. Instead of pivoting the seat on a fixed central UJ, the 6 DOF rigs have 6 motors and pushrods, so the rig "flies" by default at mid-height. It therefore juddered with very slow angle changes, because the ball and screw SFUs were lifting and dropping in short "jerks" as the brush motors (not steppers) went from cummutator segment to segment.
Most DOF platform users appear to use them for driving sims, and then there's no problem at all, because car movements are mush more abrupt anyway, compared to flight sims.
The company vehemently denies the problem, which is unfortunate, because in all other respects they are supplying a marvelous product at a relatively affordable price, and their sales and customer service is very good, despite being based in a war torn country.

Fierce_Fire•12/23/23, 10:26 PM

What do you think would change that behaviour? Im thinking of building my own 6dof rig someday and would like to prevent something like cogging

Duchess ✈•12/23/23, 11:33 PM

I upgraded my P6 with the SFU upgrade (total nightmare) and I still have the violent “jerking” motion when at the max throw distance. The rest of the movement is quite smooth, much smoother than prior to the SFU upgrade. I have read about the clogging mods, but have decided to catch my breath before I attempt another mod or update with the rig.

Jehly•12/24/23, 12:16 AM

I’m glad I’m reading about this now before dropping that kind of cash. Thanks!

DofMan1234OP•12/24/23, 1:19 AM

So far the only way I have found to make my H6 cog-free is by changing the motors to the planetary geared ones.
It's a fairly straightforward conversion, but does require a certain level of engineering skill to adapt or create the new motor mounting flanges.
On the plus side, no electrical or software mods are required if the rig has external position sensors, rather than the newer rotary encoders. It's simply a matter of bolting the new motors in place of the originals and connecting the pos and neg wires. The adapters are needed because the planetary motors have different PCD mounting holes. New ones can be made from sheet metal or adapted from the old pre-SFU worm and roller gearbox flanges with a little bit of turning in a lathe. New flexible couplers are required as well, since the new motors have 12mm diameter shafts instead of the originals 11mm. (Though I did bore mine out instead in a lathe.)
Here's a youtube video showing the old and the new motors alongside each other on an H6. If you look at the silver shaft couplers, you can see the direct drive motor cogging when moving very slowly, while the planetary geared motor coupler turns smoothly, because the motor itself is spinning 4 times faster for the same SFU input shaft speed.

A video illustrating the effect of "Cogging" when a DC brush motor ...

The phenomenon of "cogging" occurs when a brush type DC motor turns very slowly or when giving partial revolutions. The electricity to the windings is connected via carbon brushes that touch a segmented commutator, so that as it rotates it connects to each coil in turn. There are therefore points at which the energy force "jumps" onto the next...

Fierce_Fire•12/24/23, 10:08 AM

At least it's gonna take a while before I build mine but it honestly hasn't really become clear for me yet

DofMan1234OP•12/24/23, 10:32 AM

I've been into motion platforms for three years now.
I currently have the much modified H6 and previously the H3.
I also have a Yaw1, the small hemispherical ball.
I've never aspired to a "proper" motion platform with true linear actuators because of the greater cost, and possibly the larger space needed to accomodate them.
The one that Piola linked to looks really good, but I wonder what the avialability is like.
I'd considered the Yaw2, which uses the same principle of movement as my Yaw1, not using actuators but simply "rolling" the curved under surfaces. They have had severe problems meeting demand though, and going by the comments from backers, many have been waiting years for their delivery.
My H6 has been through innumerable transformations, (easily achieved, thanks to the very adaptable bolt-together construction). I now have it working really well with flight sims, but I'd be very cautious in recommending it to anyone with minimal engineering skills.
The Yaw1 is a real blast. Incredible on roller coasters and such, as it can rotate 360 degrees (and more if used via wifi !) It's real forte is VR, with minimal controls, just a yoke and lighweight pedals. I tried to incorpoarte it into my triple screen multi control setup, but it's too "agile", (which is why it's incredible in VR, in the centre of a romm with plenty of room to swing and tilt.

Piola•12/24/23, 10:35 AM

Ah this is the first Yaw

Fierce_Fire•12/24/23, 10:42 AM

I've been thinking of waiting till I finish college to use engineering job connections to build something similar to yaw2 with linear actuators for translating motion haha

How is Rhino compared to msffb2?

Curently using msffb2 and it works great in dcs, il2 even ear thunder fixed ffb. Microsoft flight sim works for me with airforce player up but web page for that is no longer active.

I am soon on the list to get my rhino that I will be mounting to my Warthog stick. Is short throw neeed if I use 7 cm extension for warthog?

DDuraCell Another question does anyone have solution to get FFB in star citizen?

TheAmazinGreat•12/24/23, 1:02 PM

Star citizen currently has no telemetry output, so the Rhino will not have any FFB but you can still use it like a spring joystick. The electronics serve as an alternative to high end bases for adjustability in the feel for damping, cams, friction, etc.

I've been using my sidewinder FF for many years now and it used to be really good, but despite having the paid versions of xpForce for FS2020 and XPlane, I've never been able to get it to work with either, it just jerks forward in one second pulses. I tried emailing the author, but never got any replies.
The Rhino however, blew my socks off when I first used it !

No comparison really. It just feels like a real plane, pulling back on the elevators while sitting on the runway, and feeling the effort reduce as you reve the engine and increase the airflow over them.
