After a while of using pimax artisan, i noticed the vision is “jumping” back and forwards as if it’s always trying to correct it’s tracking position when headset is clearly visible for both base stations and is stable on the table, (no reflective surfaces in the room). Imgur: The magic of the Internet
Is this normal?
I didn’t experience anything like this with valve index.
No, that does not sound normal.
You say they are “stable on the table”. Are they just sitting on the table or are they mounted (screwed down or attached with clamps or something similar)? The base station contain a motorized mirror which, is subject to vibrations. They need to be affixed in some way.
Sorry, I meant that the base stations are firmly mounted on the walls and headset is just placed on the table.
OK. It definitely sounds like a real issue, but (unfortunately) I don’t have any suggestions, other than to contact Pimax Support: Support : Pimax Support
Good luck! I hope there’s some simple fix that I am not aware of.
Thank you for your reply. Just finished all of your suggested tests and I gotta say, nothing’s changed. Is sending it back for RMA really the only option here?
Make sure You don’t have any RGB lightning software (like ASUS Aura) running in the background… 
I would retest with the index if you still have it. If no problems, retry the pimax. Disconnect the Pimax completely and rebooting before restarting each. Try the pimax on and be sure it is effecting game play.
Quote from another post that cured a loss of tracking issue. May help you
If none of that works you have to try reinstalling steamvr and or pitool. Then … IDK
Feeling found this issue, but other pc has auto movement although using 9axis.
Try to change the power source, may electric power make the headset to not stable.
It look the base station 1.0 is stable than 2.0
-Few days ago I retested index with my lighthouses. No shake at all.
-I tried all electrical sockets in the house, no change, pimax artisan still shakes.
-I did try reinstalling PiTool different versions and SteamVR, no change, still shakes.
-I checked 6-7 times now for reflective surfaces. They are not present within the room.
-Moments ago, pimax employee (with teamviewer) tried to up date tracking on headset (2018version) and check for tracking statistics. He said all seems to be good and that’s it’s unlikely that I’ll get a replacement.
-I tried putting lighthouses in different places, even different surfaces, no change, still shakes.
-SteamVR is unable to sleep. Whenever steamvr goes to sleep, it will wake up within 10seconds due to shakyness of pimax artisan. As I write this update, I have steamvr running and I saw ~10times “vr view” screen go black (to sleep) and almost instantly wakeup afterwards
That’s my update. A great headset with a major… MAJOR flaw.
Do you see any log messages in the web console when this happens?
It could be caused by the optical sensors on the headset, which are:
and the poser cannot pinpoint the fixed position.
What is this web console you speak of?
When you run SteamVR, navigate in the main menu to Developer, there is a Web Console. It is basically a web page connected to local server (some process from SteamVR family), which provides online log messages from all subsystems. You can use filter to filter only some, or look for particular word, etc. You can also use to change SteamVR settings in a consistent way.
It is quite handy tool to debug SteamVR problems.
Thanks, very useful, i’ll take a look.
