Gladiator NXT - jitter on stick axis

[GroowyMg]

Hey, I have two problems with Gladiator NXT, bought a month or so ago:

1. "RotZ" axis jitters. See screenshot, to compare it to "X" and "Y" axis.

I tried flashing firmware, and problem persisted. Also, I have a new problem now:

2. "Z" slider jumps from value 0 to 32767 instantly without steps in between.

I tried without success:
- turning off nearby router and speakers,
- flashing it with different firmware,
- used different USB cable,
- changing parameters like Deadzone and Precision in VKBDevCfg-C,
- opening the stick and cleaning the magnet.

Maybe I flashed it with wrong firmware? I tried "Gladiator_EVO_kmz41_v2_18_9.vkb" and "Gladiator_EVO_v2_18_9.vkb" with similar problems.

Any suggestions? Thank you.

Thank you, i opened a ticket on support site. I'll let you know here, when resolved.

Forgot to mention: i calibrated it numerous times with different firmware, but Z jitter doesn't go away.

Still, if you have suggestions, feel free to post...

Try firmware v.2_18_D from here, with reset to default and autoconfiguration before calibration.

Thanks, I tried both "_Gladiator_EVO_kmz41_v2_18_D.vkb" and "_Gladiator_EVO_v2_18_D.vkb"

with similar results: jitter on RotZ. But Z slider doesn't work at all with this version of firmware.

I also tried "_Gladiator_NXT_v2_18_D.vkb" and I get:

!!! Device signature not correct - flash fail !!!
Please check version of firmware file for this device


Any ideas?

I don't know if you've solved your problem yet, but today I discovered my Omni Throttle left hand got jittering. After trying recalibration without success, I found a super strong magnet in the drawer under the desk was the culprit. Now it works perfectly.

GroowyMg - judging by your screenshots, the twist axis (RotZ) is not fully calibrated. Perhaps something got on the sensor magnet in the grip.
You need to disassemble it and check it.

Update:

- I tried it on different PC (Win 8.1) and second issue with slider goes away! So, i guess it is driver or OS (Win 11) dependant?

- Jitter on axis persists on both PCs, so i guess it is related to a magnet. Will try to clean the magnet.

Update 2:

- Throttle slider still jumps from 0 to 1 on my win11 PC. It must be some software conflict, because i can not reproduce it on other PCs. I need to investigate further.

- Jitter on twist axis was finally FIXED after replacing "main PCB where the grips's controller is located" by the official technical support!
