PETG support material?

New to 3D printing.  Trying to print a horizontal tube in PETG with my new setup of PRUSA MK3S MMU2S.  Looked online for PETG support material, but I didn't find anything, surprisingly.  I figured support material for PETG would be common-place.  So, I asked Prusa support, again surprised by their answer of, they didn't know, but check out this video of a guy using PETG as a support for PLA, as the two don't stick to each other, when cooled. (again surprised that someone would rather have a finished product in PLA and NOT PETG, as PETG is obviously much superior material...)  Anyways, the reverse then would also be true, use PLA as support material for my PETG project.  Running at 230 degrees with a bed temp of 80 right now, and for the next one, I'm going to have to up both of those to probably 235/90 as I'm just having too many problems initially (once I get up to 1cm in height, things go rather smoothly, except for all the tool changes needed (still have an issue with about 25% of filament changes).  I've learned that PVA is used for supports for PLA, and HIPS is used for supporting ABS, but nothing on PETG...   So, question is, what filament do people use for support for PETG??!  Settings?  Thanks in advance for your help!

RE: PETG support material?

Can you print the part at 45 degrees and then you only need support to stop the tube falling over, the support and model will part with negligible effort and the support will leave negligible marking, and you can use PETG For supports and model, saving time and effort having to change filaments

The OP never replied, but I found this while doing a search and found it helpful. Thank you Joan for the suggestion.

it's one of those situations where you sacrifice a little time and filament for a better print!

I like to use PLA+ as a support for PETG. I prefer the + as seems to handle a higher temperature a bit better than non+ material. I also purge a minimum of 300 when switching between the two material types. In the video below, I don't recall which was PETG and which was PLA+, but they work just as well as supports for each other in my experience.
