Wwalmis Nah, it's probably new plastic smell from the fans 🙂

antigravitačnik•1/18/23, 1:17 PM

Yes, most likely is. But I thought that everyone would be familiar with the smell of new plastic by now. Not 100% familiar with every component/design of your board, but it seems very unlikely that it could, even under some weird conditions, produce kV of voltage, especially with most of the things running on 3.3, 5 or 24V for motors or 48V for stronger motors.

walmisOP•1/18/23, 1:24 PM

Definitely not the latter, though I have to agree the fans have strange thermoplastic smell, but it should clear up after a while.

Vulcan•1/18/23, 1:31 PM

So after calibration is it possible for x&y to be 0000 or is that asking too much precision from the hardware?

walmisOP•1/18/23, 1:40 PM

With zero dead-zone this is hard to achieve

But to minimize the error you can better balance the grip
increase stiffness near the center using spring curve mapping.

Vulcan•1/18/23, 1:51 PM

Any idea at approximately what number DCS would register an input thus impacting flight ever so slightly?

walmisOP•1/18/23, 1:57 PM

the numbers in the VP UI are +-4096 - so for example 100 is only 1.2% of the total throw

Vulcan•1/18/23, 2:00 PM

Gotcha thanks for the info

skyPickle•1/19/23, 2:48 PM

some questions on vp configurator:

skyPickle•1/19/23, 2:49 PM

1)how is 'spring' different from 'balance spring'?

skyPickle•1/19/23, 2:49 PM

2) what does saturation do?

skyPickle•1/19/23, 2:50 PM

3)what does filter do?

skyPickle•1/19/23, 2:50 PM

4) what does forced effect do?

skyPickle•1/19/23, 2:51 PM

5) what do end stops do?

skyPickle•1/19/23, 2:53 PM

6) why are my limits so different from yours? (In the photo above my X and Y (at the bottom of the second image ) are way less than 4096

skyPickle•1/19/23, 2:53 PM

7) is there a manual so I can stop asking stupid questions?

walmisOP•1/19/23, 3:07 PM

1) Balance spring is used to balance a heavy grip so it doesn't sag when you leave it at an angle. It needs to be tuned when other spring effects are disabled.
2) Saturation limits the effect when it reaches the preset level. (black line in the example). Rarely used.
3) Filter is the control bandwidth, can be tuned to get a better system response, too high can cause oscillations. Advanced feature, defaults are good.

"Forced effect" means this effect will be "Forced" or locked in and DirectX games will not have authority to override it. For example if you lock the spring effect, trim will not work from DCS. Advanced usage.
These are soft limits that will prevent/resist the stick moving further than preset throw % in each axis direction.
Not sure about what you mean exactly here. Could you elaborate?
Not yet, but will be in the works soon. There's also the FFB kit video: https://www.youtube.com/watch?v=iNhRD2Bsb8o that applies to the Rhino as well. Just the earlier version. Also the the App if you hover mouse on some controls there's a tooltip with help that pops-up.

skyPickle•1/19/23, 3:18 PM

thank you. re 6):

skyPickle•1/19/23, 3:18 PM

in my second pic posted above under FFB axes setup
Xmin 1052 Xmax 3976 center 2514 effective range is 3976-1052=2324
Ymin 84 Ymax 3217 center 1650 effective range is 3217-84=3133

skyPickle•1/19/23, 3:18 PM

isnt the range supposed to be 4096?

walmisOP•1/19/23, 3:21 PM

No, this can vary based on calibration. This is the physical data that the motor reports

skyPickle•1/19/23, 3:23 PM

the video helped. I only pressed 'autocalibrate' and after moved the joystick. I'll try again making sure the 'autocalibrate button' stays highlighted during the calibration process

skyPickle•1/19/23, 3:25 PM

7) how is 'send config' different than 'store config'?

walmisOP•1/19/23, 3:27 PM

Send only stores in RAM, will be reverted after reset.
Store - writes to Flash

skyPickle•1/19/23, 3:45 PM

8) on effects page, what does 'gain map' do?

skyPickle•1/19/23, 3:49 PM

9) is there a possibility of having an 'import settings' and 'export settings' in vp configurator? Multiple settings would make it easier to restore configurations after a firmware update as well as sharing configs. Perhaps a real pilot would be able to make a config that REALLY feels what a stick in an Apache feels like.

skyPickle•1/19/23, 3:51 PM

10) how do the numbers for gain and saturation on the effects page interact with the sliders on the settings page? In other words, why do those numbers even exist if we already have sliders?

skyPickle•1/19/23, 3:58 PM

11) in the video, I noticed the numbers for friction gain were much less than the numbers for the gain of the other effects. Why?

walmisOP•1/19/23, 3:59 PM

Gain map allows to create a custom spring response based on throw
It's already in place
Sliders control the "global" per-effect class "Volume" or "Gain" because it's possible to create many Spring effects, many periodic effects, etc using directX API. The Effect boxes in the effects tab imitate the effects that DirectX could create and if does, those will be overriden.

Basic Concepts of Force Feedback

skyPickle•1/20/23, 2:15 AM

ok so i properly calibrated the rhino. as a test, i turned all settings to 0 and sent that config. I was expecting the stick to be loose. However, it is only loose in the y direction (it will stay where i put it). In the x direction there is significant resistance, more to the right than to the left. The stick returns to center. Is this a bug?

skyPickle•1/20/23, 2:16 AM

actually it is my seat cover engaging the belt. sorry for the ridiculous observation but it is important to remember there are extraneous factors.

skyPickle•1/20/23, 2:24 AM

finally i looked at the gain map. For the spring effect, i see the deflection in all directions on the graph as i move the stick. However, there is no deflection of the stick indiccators in the damper and inertia gain maps. In fact i feel no dampening or inertia. even when these effects are enable, and set to 50% in the settings.

skyPickle•1/20/23, 2:26 AM

I guess I should enter numbers in the boxes in the effects page?

skyPickle•1/20/23, 2:27 AM

sorry if I am sounding utterly stupid. It is late here and I just got off work and had a couple of drinks.

skyPickle•1/20/23, 2:32 AM

a damped stick with low spring makes helo flying a dream

I just have no idea if its realistic or not

What kind of max psu amps should i use on the included power source?

walmisOP•1/20/23, 2:31 PM

default 7 is good

AsBurli•1/20/23, 3:17 PM

After the update of the last Firmware i get a long beep and the motors didn't work properly. What does a long beep means?
After i set the max amps to a lower value in the configurator it works like before.
Are there any other beep-codes?

walmisOP•1/20/23, 3:39 PM

Could you check the fault code in the app ?

walmisOP•1/20/23, 3:55 PM

Long beep means motor fault has occurred. The exact fault is encoded in the statusbar as shown above.

AsBurli•1/20/23, 6:37 PM

@walmis the error was fault_undervoltage. I have already discovered the cause. My lab power supply was misaligned. Was my mistake sorry.
I would also like to thank you again for this great project.

Vulcan•1/20/23, 10:19 PM

So one thing I liked about the winwing grip was the set screw to really lock in the grip to the base once tightened down. Any tips to eliminating the grip from being able to break free and rotate during extreme maneuvering? Teflon tape? Loctite 425?

Magpie•1/21/23, 11:32 AM

Aight, new issue
It seems the more spring effect a jet has, the more it throws the calibration of the end stops off

If the spring effect is low my raw x min at the joystick limit is 2120
If I’m in a plane that has a high spring effect the raw limit in the same spot changes to 2175
This means that the axis won’t actually let me do 100 percent roll in some planes

I found this out when mucking around in the m2000 and it needed a full control wipeout in order to continue with the fbw system
