RE: Trouble printing with soluble supports (PVA or Verbatim BVOH)
Nice to hear that your results are improving! I have also had some luck recently... I switched from verbatim to aquasys 120. I found that I could run aquasys at a higher temperature than verbatim. I'm not saying that the aquasys likes being printed at 235-240 degrees C, but it seems to tolerate it. I also bumped my printing speed for the support material just to keep the filament flowing well and I haven't run into any issues yet. I still need to try using two different nozzles sizes, 0.6mm for PLA/PETG and 0.4mm for PVA. I was also able to get the nozzle adaptor sold by prusa so I can use my old E3D V6 nozzles. Maybe that'll make a difference?
RE: Trouble printing with soluble supports (PVA or Verbatim BVOH)
yeah, but with the aquasys you can print it at a nozzle temp that works and then just adjust the bed temp to match what you're having share the first layer with. bvoh was definitely my goto on the MK3S + MMU. Aquasys flat out wouldn't work in the mmu. But it seems made for the XL lol
RE: Trouble printing with soluble supports (PVA or Verbatim BVOH)
so I just thought I'd follow up with this.
I just completed a 4.5 day print with petg + aquasys 120 for soluble interfaces.
E1 = Prusament Jet Black PETG
E2 = Giantarm Silver PETG
E3 = Aquasys 120
It's not perfect, but that's mainly because I think I need to tune the temps a little, but it turned out well enough, and I think it proves that the aquasys works pretty well as a soluble interface.
I ended up using snug supports since organic supports tipped over on me on my first attempt. This added SIGNIFICANTLY to both filament usage and the print time, like double. and this is what the core support looked like after I detached it. supports that tall start getting less stable, as you can see with the waviness. If I were to print this again I'd probably try to support settings and I might try to dial in temp settings a bit.

Just a suggestion, why not quickly design some sort of filler block under the helmet? One wall, lightning infill, 3-4 top layers. Then just put supports between that and the helmet. That should save significant time and material.

Yeah that’s a good idea. I want to do a Vader helm and I might try it down r that. Thanks!

Hi everyone!
It's been a while, but I finally have an update. I switched from a 0.6mm nozzle to a 0.4mm and my results immediately improved.
I also have switched from Verbatim BVOH to Polymaker Polydissolve S1, as I am unable to source the Verbatim.
Currently, I am printing the Polydissolve around 230-235 C.
RE: Trouble printing with soluble supports (PVA or Verbatim BVOH)
Would you be willing to share all the material settings you used for the AquaSys 120. That is Bed Temperature, Extruder Temp, lift height, extraction rate, and other settings for this filament that you used? I have been trying to get a print to work with 4 different materials and BVOH as I need water soluble supports but no luck. Based on your journey above, I am trying to see if I can get this to work with AquaSys 120 but not sure the optimal settings for the XL

Are you otherwise using the Verbatim BVOH settings? I'm having trouble with PolyMaker PolyDissolve and CookieCAD PLA. I'm trying to do interface in PolyDissolve and it isn't behaving well.
