Soluble Support?

Has anyone been able to print with a water soluble support? I bought a spool of E-PVA from 3D Printlife and I have not been successful with it.
The specs say to never allow it to go above 225C or it may crystallize. I am experimenting with temperatures between 190 and 215 and can’t get a good print.
Also it seems that the X1 heats to 240C when it withdraws the filament, and I wonder if that is causing an issue with the filament.
I have had to “help” the filament out of the extruder twice now so something is causing it to clog / jam.
Thanks

Would you mind sharing what speed you used? And is it still working out for you?

I use Verbatime BVOH and it works great.
