MCGU - Twist axis not working anymore

Hi,
The twist axis suddenly stopped working. I've reset to defaults, nothing happens on the axis test when I twist the grip.
It's the third issue I'm having with the MCGU since I got it last thursday, did I get a lemon?

Ok, there are communication errors when I'm twisting back and forth, so there must be an issue with the cables in the twist adapter, or something else.

Open Test - Misc tab and press Check MARS button.

Thanks, here is the result. Does that mean that the grip is faulty?

I don’t know if it’s related but sometimes both leds on the grip would turn white for a short time.

Try to reinstall the grip. May be communication errors cause problems.

You are using beta firmware. We know about this bug and will soon be releasing an updated version.
But now you can use an official stable firmware for MCG-U
http://ftp.vkb-sim.pro/Firmware/BlackBo ... 2_02_0.zipP.S. Don't forget reset to default and calibrate the joystick after updating the firmware.

It's a pedals port. Of course you can see errors on MaRS #7 because the Blackbox can not connect to the T-Rudder MaRS sensor.

As I’m away from home I’ll try this next Sunday. Thank you for the info, I hope it’s just a software problem

The firmware you used may have configuration error so the twist won't work.
Try this one:

Hi,
Downgrading to latest stable firmware (2.025) resolved the issue.
Thanks for the heads up! I will now edit my original message and remove the complaints that were unwarranted in retrospect
