We just got our Ultimaker 5 at the office and it's super exciting! Right now we're trying to print a handle, but we're having some troubles printing with PVA as the support material. The other material in this case is Tough PLA. The print creates these blobs/bulbs and strings (for a lack of a better term) both ejected on the glass plate and on the support structure itself. Since it takes about 2 days to print one handle I figured I should read up on the settings and what could be the cause. So far I've only found that Ultimaker recommends:
"When printing PVA in combination with another material, we recommend using the adhesion method for the accompanying material. For the best adhesion and print quality, we recommend setting the ‘build plate adhesion type’ to Extruder 2 (PVA) in Ultimaker Cura."
I'm yet to try this setting. Does anyone have any experience with that setting? Does it make it better? As we're just begining to learn the machine and Cura we're not exactly sure how to get rid of this problem. Do any of you people out there with more experience know if this issue could be circumvented with some Cura settings?
