Holes and glitches on vase mode #3126

Closed thiagopeixoto16 closed 8 years ago

thiagopeixoto16 commented 8 years ago

Hello!

I'm here to report two issues with vase mode. 1. "Dots" When I turn vase on for this model, it generates some "dots" over the inner part of the model, like that: glitches It happens only when I raise up the extrusion width (like the example 1mm), lowering it to the nozzle size it disappears.

2. Holes Another issue about the same model, there is some gaps that I called "holes". I've verified and there is a real travel command that skip around half of the loop. holes

I got this error today again on another vase. :cry:

:( I don't much care for spiral vase mode as a printing option myself. I've tagged it so it's less likely to slip through the cracks, but time is at a premium and there's, oh, about 500 or so uncategorized old reports still to sort through.

For someone looking to debug this, probably start seeding print statements around https://github.com/alexrj/Slic3r/blob/master/lib/Slic3r/Print/GCode.pm#L353

Something else that might be handy is to see if it still generates "holes" in the gcode if you turn spiral vase off but set perimeters = 1, top layers = 0 and bottom layers = N, 0% infill (all manual) If it doesn't break there, we can be certain of the STL input.

Well, on my build of 1.3.0-dev I didn't see any gaps. holes-1 3 0-dev gcode - noholes.zip if you want to try printing it.

The blobs look like infill or gapfill according to how Slic3r's 3d preview. Not entirely sure how that's happening. I set gap fill = 0 to see if that was getting used, no dice.

I'm going to add a separate issue for the infill blobs, makes tracking stuff easier.

Found the culprit: "Only infill where needed" was checked in your profile and that was causing the blobs.

If you run into problems with new -dev w/r/t holes please open a new issue. AFAIK it's fixed in current -dev now.
