Weird issue with 'jerky' xy movements.

[jeffyen]

I've a Gunfighter III Space joystick, and I'm having issues with jerky results while calibrating.


In the picture above, the smooth lines can be obtained when I disconnect the SCG grip and use my finger to move the stick. [So the base seems fine?] But once I attach the grip, the curve becomes jerky/laggy while calibrating. 2.83V and 3.25V with the grip detached. That's quite weird, does the mere addition of the grip change the readings from the sensors?



Any clues? Thanks!

Run as Admin and kill background running software like Razer, Logitech, Aorus, MSI, any LEDs management software, antivirus. Be plugged to the back of computer or powered USB.

I recently discovered a similar problem with my left stick. Gunfigher base, SCG premium grip. I get a jerky response similar to what your graph shows. My firmware version is 2.165 on the left stick, which has the jerky response. Interestingly, my right stick, with firmware version 2.115 is very smooth. I've been looking for the 2.115 firmware to see if that might be the issue. Is there a way to extract version 2.115 from my right stick so I can upload it into my left stick? I also have 2.118 on my T Rudders, and it is very smooth.

I changed the firmware from 2.165 to 2.115 and it fixed the jerky response for me. Also, the buttons on the grip had a significant delay, and that is now fixed.

Try one of the latest firmwares from here, for example, 2.170.

Thanks all! Ron61, yes 2.171 fixed it. I guess https://www.vkbcontrollers.com/pages/downloads will need to reflect the new drivers. Cheer!
