Problem with spiralize in CURA 4.3.0

[pdwpackrat 0]

Having an issue with spirializer. seems to be an issue with CURA 4.3.0

STL of:  I Dream of Jeannie

I believe  I downloaded the original bottle stls from : https://www.thingiverse.com/thing:3192392

 

I scaled teh solid version  down from 214mm to 100mm within Cura, set spiralizer  , but it generates gaps in the spiral.

 

I then re-scaled befor cura, made new stl file. at 100mm  (Height), but spiralized had the same issue.

 

tried many settings for quality, smooth specialized contour,  and adaptive layers.  no real change.  

if I resize it back up to 214 mm within cura, and it seems ok then.  

 

I'm at a loss.

 

Attached is gcode, and stl file

It's not just the spiralize mode that's unhappy with that model. You can still see problems with spiralize disabled. For some reason, Cura is unhappy with that model. Sorry, I don't know what the problem is.

I had printed this model with an earlier version of Cura, about 5 months ago. I did not notice the issue then, it printed fine. Well, not quite. It was weak near the upper bulge, so  I was going to print a new one using a 0.40 mm nozzle,  pretending to be 0.50 mm to make a thicker spiral. That is when I saw the issue. I had started the print before I noticed the issue in Cura  realizing it was not going to complete correctly.

No explanation as to why but

Switch 'surface mode'  to surface and turn off 'smooth spiralized contours' seems to work.

 

Cant seem to get a bottom layer to it tho.

confirmed those settings,

note: surface has no top or bottom.

it seems that  spiral just not working right

 

going to fake  it, for now.

surface both

wall count 1

infill 0

top 0

bottom  4

nozzle set as 0.50 with a 0.40mm physical   for thicker lines

 

tried.. failed 

- nope  too shallow of an angle..  will 

too steep around 27 mm
