[Replied]O no my pimax 5kplus cracked!

Not good then if those were sent out to people. Also, I don’t doubt users here are also treating them “very gently” the cracking is caused by some other anomaly.

Yes, I think we should all be concerned but Pimax actually did address this issue. They did say they were aware of this situation and began an investigation and would work with everyone who has this issue to resolve it. Now that might not be everything we wanted to hear but they were not silent on this issue.

I imagine they are still evaluating this issue. I suspect part of the root cause is overtightening screws. But that may only be one component of a series of things causing it. Like mixed with thermal stress as well.

Hi,
Being aware of a problem and solving it are two different things. I don’t know how long they plan on investigating. If over tightening of some screws causes cracks, then the material seems too weak. I would gladly accept a somewhat heavier hmd, if it is solidly built and strong enough to handle extensive use without cracking.

Overtightening fasteners doesn’t mean the material is too weak. Just that a specification needs to be in place.

A friend of mine had his rear end changed in his camaro. A friend helping with the change said to be careful not to overtighten the driveshaft bolts. The driveshaft U joints spec was if mem serves was 30 FT pounds. Over or under torquing these bolts can cause failure. In this case a potential safety issue.

In the case of the headset the screws will being metal vs plastic will be stronger. A gasket or rubber O-rings can help reduce stress on housing by allowing wiggle room. But also requires consistency in the torque used in assembly.

Myself I would thicken wall material slightly & shave 0.5mm off seam edge & add a rubber gasket between the seams.

might be worth checking that the screws are not too tight , maybe they use cheap powered screwdrivers with inaccurate torque settings

Is this foam sandwich between two pieces of plastic, looks a lot like foam filled plastic which would explain the light weight.

That is interesting. I have never seen such a material.

Never hit anything. I was only using my 5k+ sitting in my simrig.

So far so lucky. Though you’d think the 3 musketeers would have had a crack by now. Which to mean suggests more likely over tightening.

I mean they need to change the housing for sure but there are thousands of headsets out there already. how are they gonna manage that? the person who decided on that material and that edgy design… my oh my…

Someone know where to find the pictures of the @Sjef 5K+ teardown?

Again if a headset was likely to break the 3 would have broken it. My 2 are also still completly fine. This suggests the over tightened screws putting stress on the housing as reports housing was not impacted. A rubber gasket/o rings will help but key is standardising fastener torque.

Think was in the firmware poke thread. @Sjef?

Screw torque may be an issue but that brittle plastic will not survive a controller slap anyway! No other headset has these sharp edges… for good reason.

Look at the prototype. It had rounded edges.

if there are any

The m1 I beleive had the rounded edges & think the musketeers have hit the m2 with controllers.

See RoV review & @Sjef teardown. There are screws.
