With release candidate 4.0.0, when I turn my head to the left all is fine, but when I turn my head to the right, the head in the GUI follows movement, then turns left and starts bouncing off an invisible bumper.

The first time I callibrated mine my pitch axis hit a bump at about 60 degrees and would yaw about 15 degrees and then recenter at 90.

In my case redoing the calibration and spending more time with it fixed the bump and it worked fine from then on. Only other difference between 1st and second pass at calibration was that it was well warmed up on the second attempt. First was about 3 degrees cooler and hadn't stabilized yet.

I did 10+ calibration attempts. The tracker is warmed up for 13+ hours now. I also tried it with and without ferrite core (previous posting was written without the ferrite core attached to the cable), which doesn't change anything :(

I've had this Lasse B. Not sure if it's a bug, I've raised it with Rob. I had it with Top/USB Right but the minute I switched it to Top/USB Left it started working ok. Does that do it for you too?

I have it when set to Top/Left, as shown in the previous screenshots, but when I set it to Top/Right the bouncing is mostly gone. All that remains is some slight overcorrecting.

Interesting. I saw it the opposite way around. Rob is aware, anyway, he'll take a look-see. I think it's an orientation thing maybe, I've seen it here.... but re-did the mag calibration and it went away.

Found it. I play-test at my desk, which faces almost perfectly North. If I recentre the view facing east or west I can see the issue. Will fix for a release tomorrow.

I just started using opentrack with this, what a great little programme, it was difficult to track down but I found it in the end, this is a question to brumster and pocketmoon, I am using it ETS2 thanks brumster for the vid you did on that, will there be a profile we can save in the edtracker UI so we can easily switch from playing other games then to ED for example, I did what you suggested and turned down the sensitivity in the UI so we can switch between games easily?

I took the plunge and ordered a magnetometer version. I have tried everything to get the drift sorted on my old one to no avail. Time to upgrade.
Thanks for putting this together guys!

I'm unable to recenter the ED Tracker with the defined recenter Button in the gui.

I use the GUI 4.00 and defined F3 as the recenter Button in the Gui and in Elite as well ( Reset Occulus Rift Orrientation ).
I minimized the GUI but ingame ( Elite ) the Keystroke is not recognized! It only recenters when i have the GUI maximized and activated !
Does anybody knows how to solve this problem ? Any Suggestions?
By the way Great work i love the 4.00 Version
Thanks

Found another issue. After playing a while I had to look down and left for a bit, and when I looked back up and straight ahead the tracker started to send movements on its own. It kept turning the head on the GUI to the left while trying to correct for this wrong movement with quick and short movements back towards the center, but never enough to actually do center the head. Every couple of seconds it would try a bigger correction attempt, resulting in a stronger nudge towards the center, but that too wasn't enough.

Workaround was to click the Auto Gyro Bias button.

Here's a screenshot of what the error looked like in the GUI. I had yaw scaling increased to make it more visible.

Try setting ED, opentrack if used, and Edtracker UI to 'run as administrator' in Windows compatibility settings. This solved a similar problem for me, might work for you, idk.

Just got my confirmation email for shipping. Can't wait till it gets here. Been messing around with FaceTrackNoIR and, while it sucks, gives me an idea of how good tracking can be.

Hi guys !

Today, I did some overclocking stuff on my Gigabyte Z77X-UD3H, and I was just going crazy because my mouse was not well recognized : the cursor was bobling when I moved it.
Then I hit my headset with my left arm. The cursor has moved, omg...

The EDTracker is recognized like a mouse on the UEFI/BIOS of my Z77 mainboard and enter in conflict with the real mouse.
I think someone could go crazy to find out why his mouse don't work well on UEFI so I recommend to test this eventually with an other UEFI motherboard just to confirm, and put this on the website/user guide or something. :p

I've been using EDtracker with opentrack, and not the GUI for a couple of weeks now and it's been great. However I've been starting to get more yaw drift, so loaded the GUI to calibrate but now cannot get it to detect the tracker.

Seems weird as it connects to Opentrack fine.

Any ideas please guys?

Does it list the COM port at all in the drop down? As an "Arduino Leonardo"? If you bring up the Device Manager and browse to Ports (COM & LPT) is it listed under there?

If not, I'd suggest the old USBDeview clean-up of unwanted COM ports/drivers and see if that fixes it... (in the user guide)
