Problem printing PLA & PVA as supports
I have an Prusa i3 MK3 w/ MMU2, using Hatchbox PLA 1.75mm, and Sainsmart PVA 1.75mm. PLA is on position 1 and PVA is on position 5. Using PrusaSlicer-2.1.1 and both the printer and the mmu are up to date on the drivers as of today 12/20/2019. I'm using the print settings in PrusaSlicer of 0.20mm SOLUBLE FULL MK3. Filament position 1 is set to Prusament PLA MMU2, position 2 is set to PrimaSelect PVA+ MMU2.
The problem i'm having is that after the first layer of PVA goes on the board and switches over to the PVA, it just pools in the wipe tower, does not move, then eventually stops and tells me that there is a problem with the MMU2, I've changed the hot end temperature up and down at 5 degree intervals all the way down to 175 degrees for only PVA and up to 205 degrees. Still no luck. Anyone have any suggestions?
