bad results using PVA as support-material

[simonbmco 0]

hello community!

 

using extrudr MF PLA as the mainmaterial and UM PVA as supportmaterial, i always get tiny holes in the surface of the MF PLA, at the places where the two materials touch. the rest is acceptable!

anybody is fighting with the same problem? how could i get rid of those?

 

hopefully the attached photos will help!

greetings

Never seen that before... Are you unsing a prime tower?

what do you mean with prime tower?

the printer is standing on a not very stable desk/board, it is shacking a bit. (unfortunately this is the only available place for it right now) you think that could be the problem?

The prime tower is a little tower that prints between material change/layer change and will prevent polution from one material into  the other. You can select it in Cura in the dual extrusion settings.
