Obviously there is no retraction when moving between the print and the purge tower which leads to a lot of stringing. Is there a way that the the slicer retraction settings will also be considered when moving away from the main print?
Thanks, Martin
Oh yes….Slicer is Simplify3d and I’m using Chroma.

Hey @martinnyhc, thanks for reaching out. If you are using S3D with Chroma as a post-processor, any changes to improve stringing would have to be done on S3D first. We found this article here that has suggested S3D settings to solve stringing and/or oozing. Hope that helps!
Hey @martinnyhc, can you set your extra restart distance to 0 (photo attached)? That should help. Let us know if you continue to see the issue!

Yes, but my S3d profile is working perfect. No stringing at all. To me it looks like Chroma is not using the S3d retraftion settings when moving between the main print and the transition tower.
Ah, I see - okay, thanks for clarifying that. Could you send the GCode produced by Chroma and the GCode produced by S3D to alina@mosaicmfg.com? We will take a look and compare. It may be worthwhile to take a look at your Chroma printer profile as well (Profile > Printer Profiles > Export). Thanks!

My S3D profile is well tuned. No string at all when printing without Palette.
Please find pictures. files and profiles here: https://www.dropbox.com/sh/3j57sjzk1w6mj...
Thanks, Martin
Thanks for sending that over Martin, please give us some time to compare these files and we'll let you know as soon as we can. Thanks for your patience.

I have a extra restart distance of -0.1 because otherwise I see blobs. When printing single color I have no stringing issues at all. So I'm wondering why this is the case when printing multicolor.

I realize this is a older thread but I would add to this.
Since S3D does not know about the Palette 2S S3D does not realize that the extruder is going to be moved to the purge tower and thus it has no way of knowing there needs to be a retraction. What I find is little strings from when it leaves for the purge tower and again when it returns.
What I would love to see is a setting to enable retractions and specify the length of the retraction before and after it goes to the purge tower. Specifically when Chroma inserts the code to go to and create the purge tower it needs to retract before it starts moving to the tower and again before it goes back to the print. This would help eliminate the stringing and greatly improve the quality of the prints.
Here is an example of how it is affecting my prints:
as you can see the stringing kind of ruins an otherwise perfect print.
