I think I need to slow down wiping of the PVA filament I'm using

I think I need to slow down wiping of the PVA filament I'm using

I just got my MMU2, and the first problem I noticed is that the PVA I'm using needs to be printed much slower than the defaults.   I'm printing with soluble interfaces, and I've slowed down the speed of support interfaces in the print settings profile, and that has helped with adhesion within the print, but it makes a mess of the wipe tower as it just goes full speed there.

In PrusaSlicer, I can't seem to limit the speed of a filament profile but I can limit the flow rate (perhaps this is what I need to do?).  I would love to be able to specify a max speed within a filament profile.

Any suggestions?

You are correct, dropping the max volumetric flow for a filament will also drop the top speed it can print at.

I print Prusament PETG plus PVA (Primaselect).  Item is printed perfect now but wipe tower is a mess. The wipe tower can create crashes. I have to pause the print frequently to cut strings and blubs from the wipe tower to avoid crash. How should we set up this in Prusaslicer 2.0 to have good printed item plus wipe tower?

I bought the MMU2S primeraly to print 1 filament (PLA or PETG) plus 1 filament PVA soluble, so would be great if we get this working. 

Thank you for tips!
