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.

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.

From an academic view point your research is interesting.

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.

Rat0S for V-Core 3 hybrid
Sorry I haven't used Github before (except to download the occassional CAD file). I think if I attempt this I will make a mess of it. Is it possible for you to extract what you need from the printer.cfg file I posted above?
Some of my values might be slightly different because my Beacon offsetr to the nozzle is slightly different as I use the Microlight Print head instead of a Rat Rig one.

Rat0S for V-Core 3 hybrid
FYI (and amusement)
These are the overrides I have in printer.cfg
Note I use the Microlight print head with Beacon which has a different Y off set and I use a CPAP fan hence the fan settings. I use and adxl 345 board mounted on the top plate of my print head rather than the Beacon's Accelerometer.
I use two separate fan ports on the Octopus for the two fans that cool my stepper drivers.
Otherwise everything else is standard V Core 4 for the purposes of RatOS set up.

Rat0S for V-Core 3 hybrid
Loving the V-Core 3 hybrid and RatOS made setting it up so easy, only left me a couple of minor steps as per this thread that I needed to do.
I left the Y stop in the current V-Core 3 location hence the only other changes I needed to do.
