Horizontal level - Adjustable or?

General discussion
1

I’ve seen this mentioned on YT and other places and I have the same problem too…

The horizontal level seems tilted by a few degrees (say, 3 to 5 degrees) on my headset - in the PiMax Play environment. No matter what I do I cannot seem to correct it no matter how much I tilt my head to re-(center / set) the view. Strangely it is usually OK, or not noticeable at least, in most games and their menus but not all, eg: Google Earth and Steam menu is affected to various degress - oddly only sometimes!

It doesn’t seem to matter which module I use in my CS (50ppd or micro-oled) either, they’re affected the same way (equally).

Any ideas why? Solutions? Tweaks?

Alright. I’ll check with our engineers about this and see if there’s any solution we can provide.

Thank you, that would be awesome of you, PQ. It doesn’t really warrant returning the headset (frame) as a warranty replacement, the headset otherwise works great.

If it can be simply adjusted by changing a byte somewhere in the code of a dll, exe, or a cfg file then that would do for me - just point me at it. I’d be happy to test and report back on any theories - I’m just now out of ideas currently…

Indeed. I’m wondering if removing the SLAM file and restarting the service would resolve the issue.

Guide me, please. Which file is the SLAM file?

There was never an issue with this before. I did notice it after an update (cannot remember which, maybe from 1.33 to 1.34 somewhere?) but was unsure of my thinking if the problem existed before or after that.

As I said, it’s not a deal-breaker issue, just annoying. But then I noticed others responding to me in a comment I made in a YT video that they were having the same issue too, so I thought it would be good to get to the bottom of it and hopefully come up with a solution I can share to those people too.

You can try deleting this folder:

C:\ProgramData\Pimax\slam

Then restart the service.

You could also try covering all four cameras and then uncovering them to see if that helps resolve the issue.

Tried deleting the “slam” folder and covering the cameras. Nothing changed, still the same issue. Even deleted everything and reinstalled (to v2.02, firmware v1.17) and no change :disappointed_face:

Wanna follow-up if this issue still persist?

Hi.

Yes, sorry. issue still persists. I haven’t used my VR a lot lately, mainly due to “life”.

Looking at some of the calibration files shows values that are not near zero for x/y, I don’t know what the labels refer to specifically but I don’t want to touch them in case I make something else “break”.

If I get those labels for you can you tell me what they refer to? I might be able to tweak them so the image is better tilted. If all else fails then I’ll have to send the headset back for warranty :frowning_face_with_open_mouth:

I’ve had the horizontal issue since the very outset with my PCL and brought it up over a year ago. Glad it may not just have been me.

Noted. I’ll speak with the dev team about this and see what solution they can provide.

Afraid I can’t provide any information about those values.

If you could have a chat with the devs, please, that would be awesome of you! Thank you :clinking_glasses:

(edit: What might be beneficial in tracking the source of the problem might be:

  • How does the headset determine what is level?
  • When is the “leveling” function performed?
  • Is it a sensor mounted on the carrier or is it in the module(s) (I have super and micro-oled modules)?
  • If it is a sensor, is it affected by magnetism or strong electrical signals (PC, monitor, RGB, etc.)?

Hope the devs can shed some light on this.
