1.2.9 Spiral vase unexpected extrusion in place of travel move #3755

Open motorb opened 7 years ago

motorb commented 7 years ago

Silc3r version 1.2.9 Windows 7, repetier host 1.6.2

Using spiral vase to make a part with a bottom layer, the travel move between the last infill track and the start of the spiral vase is an extruded move. This leaves a visible track of extrudate across the part. Issue repeats with alternate layer heights, part dimensions etc.

Screenshot included highlighting the offending command in repetier preview pane and gcode editor spiral vase issue zip.gz

thanks

@motorb Please read and edit your issue to provide the requested information: https://github.com/alexrj/Slic3r/blob/master/.github/CONTRIBUTING.md

I can't tell what's going on with what you provided.

Then try again with https://bintray.com/lordofhyphens/Slic3r/slic3r_dev/1.3.0-dev-a193297#files to ensure that it's still happening with current master (you should be using current master anyway).

Apologies, for some reason github isn't accepting the .zip file with the stl and configuration files.

motorb commented 7 years ago

OK, so if I rename my zip file to gz it will upload. great. I'll edit the issue now.

lordofhyphens commented 7 years ago

Don't forget to add a screenshot from Slic3r's plater too and check with 1.3.0-dev (linked above).

lordofhyphens commented 7 years ago

That white line in your screenshot looks like a travel move to me, so I really don't know what you are seeing that is an issue.

motorb commented 7 years ago

It's an extrusion move, highlighted as I've highlighted the Gcode line in the pane on the right. Further confirmed when I printed the part....

alranel commented 7 years ago

Yeah please, test with 1.3.0-dev.

alranel commented 7 years ago

@motorb, can you confirm this is fixed using a fresh build? You can download it at http://dl.slic3r.org/dev/

Version 1.3.1-dev Build commit: d17659b67c65bb5003ec92bf0d56ed7f8810e970

Occasionally moves that should be travel moves are generated with extrusions. Models similar to the attached one with "three spokes" show this on layers other than the first one as well. slic3rbug Slic3rBug.zip config.zip

This is not in spiral vase mode, but since it seems related I decided to add it here.

By the way this is a regression of sorts. For example Slic3r-master.2018.04.26.1669.8a93fbb.32bit.zip (which I had laying around) does NOT have this problem when slicing the exact same object running on the same machine (so the exact same configuration as above).
