Retraction when moving between print and purge tower

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.
