Soluble supports?
Anyone have good information on the use of soluble supports? In general and specifically with the XL and the different nozzles? I see the BVOH on the Prusa site that says it is good with PLA, and some PVAish material that implies it is good with PETG too.

Prusa has a guide on how to do this on an XL in PrusaSlicer: https://help.prusa3d.com/article/combining-materials-xl_498103
I’ve not used soluble supports, instead I’ve been combining PLA and PETG as suggested in the article. They don’t bond well to each other making for easy support removal.

Interesting, thanks. I’ve been happy with how well PLA come off of even PLA prints. PETG supports are almost too bendy and suppple and sticky to the print to crack off. That is on MK3/Mini single extruders.

PVA…
Relatively, very expensive and can be tricky to print with. Problem 1 is the stuff drinks moisture like no other material. Once it’s removed from a vacuum seal if you don’t use it all chances are the next time you try to use it it will have soaked up moisture from the air and expanded out of tolerance. We gave up on it. What has been working brilliantly has been PLA vs PETG. PVA can do more use cases and a mechanical hold can make pla/PETG tricky to remove, but set supports to soluable for full contact and for almost all use cases you will get the same result as with PVA for way less and way more reliability. This is now my primary task flow for every print on my Tenlog idex and my E3d TC (TBH, Im still testing my brand new XL5 and have yet to switch to PETG)
