Ooze shield at single head prints - strange...

Recommended Posts

Today I tried to use the ooze shiled function in cura for a single-head print.

Cura does it but strangely follows the whole contour of the part - means not just applying a straigt contour around at max perimeter, no, it really applies something like a "skin"...

Has anybody tried this before? Experience?

Or is it a bug???

I think the ooze shield is very close to the object (2mm). I had a case where ooze shield and object were kind of merged and the object was partially destroyed. Thus, I extended the distance in the CuraEngine to 5mm and will check if it helps.

Another issue I had with the very close ooze shield is insufficient cooling of the object.

However, I have the ooze shield activated all the time, even for single extrusion prints but with them it is never printed. I wonder how you drayson managed to have the ooze shield with a single extrusion print. Have you acitvated some support on the second extruder?

Nope, but I was also astonished, but I think found it out...

my setup: Cura 14.07

- checked the oozing-box

- support is on first extruder and everywhere

- bed adhesion is brim.

- second extruder is not used.

In layer view it is applied and acc. to my gcode simu it should be printed too. But this is only when using support anywhere - switching this off, it disappears...

When thinking of an ooze shield I expected something like a wall around the object based on the projection, not a cocoon :smile:

On the other hand it is clear that it is nearby the object to avoid oozing onto it.

b.t.w. - how have you changed the spacing from 3 to 5mm ?

      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
