Pro2 Different prints with same profile

Postby karim_2402_3D » Wed Jul 25, 2018 7:48 am

First of all, I'm very happy with the Pro2!!
What i noticed is, when printing with only the right extruder, it's always printed with that shell wrapped around the object.
And, as you can see, the support net ist printed with the left extruder in red.

So, it doesn't bother me, just want to know why it behaves likes this, because I'm selecting the same profile (High Quality PRO2 PLA)

The red ones are printed with the left extruder, the white ones with the right one.

That is called a wipe wall, read this topic viewtopic.php?f=3&t=9939

When you print ONLY red, then only one extruder is used for the entire print, no wipe wall is used.
When you printed with the other extruder, you also used mixed settings for raft where BOTH extruders were used invoking DUAL EXTRUSION. Dual extrusion enabled wipe wall to prevent contamination of your white print object with tiny specs of red filament as the nozzle crosses over top while printing the object.
