Updating Pi has frozen. Not sure what I should do now..
Crashing out an rebooting has fixed the issue.

ESUN ePAHT-CF bridging issues
Do thick bridging and 0.8 bridge flow cancel each other out to some extent?

ESUN ePAHT-CF bridging issues
Lehvoss say they have now further improved on their PPA and it is used now by Bambu Labs and several of their other partners.

ESUN ePAHT-CF bridging issues
BTW I can confirm after a meeting with Lehvoss today(suppliers of the raw pellets for that material) the ePAHT-CF is actually PPA-CF.

ESUN ePAHT-CF bridging issues
I use Orca Slicer these days. Thick riding helps sometimes and other times causes more issues. I have never found great bridging options.

ESUN ePAHT-CF bridging issues
I don't use 25% fan all the time with ePAHT....that would decrease interlayer adhesion. I use the minimum fan necessary. Bringing and overhangs with any nylons is always challenging.

Regular surface distortion pattern towards end of larger first layers VC4
The only two reasons I stopped using it were:
1. Improve Beacon touch probing accuracy (although I noticed no degradation in first layer quality)
2. To test the Titanium rail for @Mike-Toro3D and give him some feed back.
I have kept using it, because with my newly installed 3.1 hybrid upgrade kit I doubt lightening the Y axis will have much effect on IS recommended results (From tests others have donewith the hybrid upgrade it seems that weight savings on the gantry have much less of an effect than before the hybrid upgrade)....but at some stage I will probably remove it to be sure. As X recommended IS shaper results are less than Y for some of the people who have upgraded with the VC3 hybrid upgrade kit, it seems still worthwhile to run the Microlight print head though.

Regular surface distortion pattern towards end of larger first layers VC4
I used a bare linear rail on a 300 with great success in the past.

I suspect you would have you increase the diameter of the carbon ros to cope with the longer sun of the 500.
The good thing about using rods made of any material is that like using a bare linear rail there is no bending due to dissimilar materials having different thermal coefficients of expansion.

One way to get a gauge on the effect of a longer titanium tube vs a shorter one is to look at the resulst of 500 vs a 300 using a titanium tube.

In my case it is unlikley that there are any further gains to be had from improving how the heat from the hotend is contained because I don't have any issue to detect an improvement on. It may be that some people using titanium tubes still have some residual issue. The other plus to the Titaniumm support is of course the lighter weight of the Y gantry.

I think we have a good indication of how titanium (or a similar weight steel- if possible) linear rail support would work from the many people (like myself) already using this solution.

I think the PrusaXl and some other printers appear to use Steel X linear rail supports. I feel it is better to fix the root source of problems where possible rather than try and mitigate them. It is time for Rat Rig to address this issue at the root of the problem instead of people having to come up with band aids.
I think you guys have done a very good job of root cause analysis but it is now appropriate to have root core correction.

I use a Toro3D Ti tanium Tube. This problem is a complete non issue for me on my VC3, 300. I never bother to heat soak before starting a print.
I also use a Micolight print head with a top plate printed in ePAHT-CF which probably transfers less heat from the hot end to the carriage, but I suspect this may not be a contributing factor. anyway. My bed Meshes are completely stable from cold to hot.

RatOS Configuration repository error.
Applied 'IT Crowd fix'. (Turned it off and on again). Then did Klipper update.
Still getting error message.
Applied IT Crowd fix again.
Now rebooting and working successfully.
