Re: Ooze Shield Is Printed In Wrong Order

I was confused by the printing of the ooze shield and prime pillar also. What I observed was:inventabuild wrote: Yes, I tried just two processes also and checked "Continuous printing - Layer by layer". Going into Prepare to Print! and viewing the tool path S3D does not cycle through the parts correctly if you look at enough layers. It will not continuously cycle correctly like the following illustration if Part1 and Part2 are both part of the same part (meaning a Dual Extrusion part):
PrimePillar1, Part1, PrimePillar2, Part2, PrimePillar1 Part1, PrimePillar2, Part2, etc,
S3D needs to fix this so the user can determine the order of parts to print.
T0 - Prime Pillar / Oooze Shield
T0 - Part layer 1
T1 - Prime Pillar / Ooze Shield
T1 - Part Layer 1
T1 - Part Layer 2
T0 - Prime Pillar / Ooze Shield
T0 - Part Layer 2
T0 - Part Layer 3
So S3D is smart enough to use the tool on consecutive layers, before switching tools and printing the prime pillar or ooze shield.
I haven't experimented much with the "Extra Restart Distance", but I believe a negative distance value (-.1 or -.2) will advance the new color which will prime the new color. In the this step, the old color would purge from the shared nozzle.
So I would use the prime pillar for purging, and the ooze shield to ensure the new color is printing consistently before the actual object.
