Ok with just USB connected and on the VP main board shorting data in (D1) with GND causes 24 out of the 48 button positions to light up only.

Mike T•2/8/25, 7:23 AM

@walmis….FYI the Shift register is not connecting to any proprietary grip…….its connected to my own custom buttons and switches on my DIY collective …..

walmisOP•2/8/25, 7:31 AM

Okay, not sure - wiring looks correct, maybe the s/r is indeed faulty.
Can you try soldering a wire from GND to any of the S/R Dx pins - it should light up a button constantly for debugging.

walmisOP•2/8/25, 7:33 AM

If all else fails you can submit the order form for a replacement

Hi! Quick question: since the new Firmware and update, I'm having a mini problem with the Taog Huey on msfs2024. I have a mini lag when I click my TR and it releases the force...I didn't have that before.
Now I've recalibrated my FLANKR and readjusted my various effects and parameters, but it still persists. I'd say it does that 99% of the time. And that's just with this helicopter.
If anyone has any ideas? Thanks

Dimexi•2/8/25, 8:45 AM

How does the warranty procedure work? I have a failty ffb board which doesnt turn on

NIKO_BG•2/8/25, 9:45 AM

Hi! I have a problem with disconnecting the motors while playing, cant figure out if it is something to psu or software related

Mike T•2/8/25, 9:50 AM

Hi @walmis......not sure what you mean.....I gather Dx means any of the 32 pins on the SR....right? Is that not the same as wiring a switch between gnd and a pin ....like in the pics I showed above? Pressing the switch shorts gnd to pin (unless I misunderstand your request).......in which case no button in the configurator lights up.

Mike T•2/8/25, 9:52 AM

I also tested gnd pin on SR (red probe in diode mode on multimeter) and black probe to each data pin and i get 760mV. (as per following instructions: You can check if the pins are making contact on the grip side by following these steps:
1. set multimeter to diode test ( -⯈⊢ )mode
2. disconnect the JST plug, and with the multimeter red(+) probe touch the GND pin on the JST exposed pad
3. go through all other pins with the black(-) probe - it should read 500-800mV if not, it's not making contact it will read OL)

sydost•2/8/25, 10:09 AM

@walmis can you help with @Dimexi ’s problem?

Dimexi•2/8/25, 10:41 AM

@walmis measuring from the board, I get very even 5V from the USB and from the backside of the board, there is very even 3.3V. So the power section seems to be working, but usb recognition does not work.

walmisOP•2/8/25, 10:57 AM

I suspect the USB female socket is faulty - can you check if the D- or D+ is shorted to GND ?

walmisOP•2/8/25, 11:00 AM

When this happens can you enter command "reset" and hit enter - after the board restarts - do the motors come back online?

NIKO_BG•2/8/25, 11:01 AM

OK will try

Wwalmis Click to see attachment

Dimexi•2/8/25, 11:02 AM

Checked from the cable and also from board itself. Not shorted

walmisOP•2/8/25, 11:06 AM

Data pins also not shorted to any adjacent pins ?

Dimexi•2/8/25, 11:08 AM

No, cross checked all the usb pins for shortcuts. As told, the led flashes, the buzzer beeps twice and then led shuts down

Dimexi•2/8/25, 11:09 AM

Or are you referring to the rs-485 data pins?

walmisOP•2/8/25, 11:09 AM

Windows throws the USB unrecognized popup ?

Dimexi•2/8/25, 11:09 AM

Yup

Dimexi•2/8/25, 11:11 AM

Checked also the board under microscope, no shorts, a lot of flux residue, a litlle excess solder paste(pearls of solder on some capacitors) no visible burnt components

Dimexi•2/8/25, 11:13 AM

Now i need to go walk the dog, but I can continue to solve this if you have ideas. I have access to hot air blower, soldering iron, oscilloscope. You name it. I work as electrical engineer so…

walmisOP•2/8/25, 11:19 AM

Well, if you can measure the D+ and D- continuity coming from the cable end (pictured a few messages above) to the MCU pins, that could be helpful:
Marked the pins here

walmisOP•2/8/25, 11:24 AM

In the unlucky event that it's unfixable you can request a replacement via the order form

NIKO_BG•2/8/25, 11:56 AM

Ok, It happened again, I typed "reset" and enter. Here are what come next: usb connect, and the motors x and y not runnig, after power button off and on , the motors whent running

NIKO_BG•2/8/25, 12:02 PM

and here is telem log

walmisOP•2/8/25, 12:16 PM

Hmm, according to the log both motors show active at 13:41:52

NIKO_BG•2/8/25, 12:39 PM

Actually they were without cogging effect but at the bottom right of vp configuration there were motor x and y offline, after switching of and on the power button they went alive

Wwalmis Well, if you can measure the D+ and D- continuity coming from the cable end (pic...

Dimexi•2/8/25, 12:50 PM

D- does not connect to usb, so there is a break somewhere. Can you check from layout the trace and if it is fixable? I could try to make a wire connection to connector

Dimexi•2/8/25, 12:56 PM

Or just replace the board, whichever is more suitable to you

Dimexi•2/8/25, 1:00 PM

D+ goes through to the mcu

walmisOP•2/8/25, 1:02 PM

You mean on the board itself?

Wwalmis You mean on the board itself?

Dimexi•2/8/25, 1:02 PM

On the board itself. Measured between the 4pin connector and mcu pin

walmisOP•2/8/25, 1:04 PM

Here's the layout, you can check it:

Dimexi•2/8/25, 1:16 PM

That first resistor seems faulty? It sometimes reads 40 ohms, but when measuring to the chip pad, it doesn’t read anything? Whats the nominal value of it? I have full series on 0603 resitors here at home so i could try to replace that

walmisOP•2/8/25, 1:21 PM

it's 22ohms
Hmm, Maybe bad solder, I think you can try to remelt both pads

walmisOP•2/8/25, 1:22 PM

Anyhow it can be shorted, it's not critical

Dimexi•2/8/25, 1:25 PM

I will change it, not a biggie. Yeah it should be just fine if it is simple short. After all, it almost boots up. But i wonder why the led doesn’t stay on after the beep?

Dimexi•2/8/25, 1:29 PM

Quite easy with these.

walmisOP•2/8/25, 1:52 PM

The LED indicates USB status, therefore it shuts off when no USB link is present

walmisOP•2/8/25, 1:55 PM

Did it happen with previous firmware?

NIKO_BG•2/8/25, 2:12 PM

Yes but not so often.

NIKO_BG•2/8/25, 2:13 PM

Could it be any problem with the board?

Hammer 1-1•2/8/25, 6:21 PM

can anyone point out to me where one could find some mounting options and some aftermarket parts for the rhino? Ive got a next level racing flight seat pro and looking for a way to mount this to my pit without having to fabricate much

Hammer 1-1•2/8/25, 6:29 PM

or is it more feasible to just post this thing onto the floor?

Wwalmis Anyhow it can be shorted, it's not critical

Dimexi•2/8/25, 10:14 PM

when touched the resistor with soldering iron, the resistor physically broke in 2 pieces. Cleaned the pads, soldered new 0402 22R resistor, cleaned the excess flux, and voilá! It's Alive!!!

Dimexi•2/8/25, 10:14 PM

Thanks for the support!

smitty•2/8/25, 10:34 PM

defect boards seem pretty rare but it's good someone like you got it
