cura screw up?

So, what am I doing wrong that confuses cura?

Re spam issue ... is it that it's deciding that there is too much skin tone and therefore "porn" ??

At one place I worked they had such a porn filter - the problem was that marketing (bless their cotton socks) made a point of highlighting business news by sending out scans of cuttings of the Financial Times that tripped the porn filter every time! (the paper used was pink - not sure if still is).

Annotated screenshot shows both your original and increasing h to 13 in line 19. Made OpenSCAD preview much cleaner, but can't see any significant difference in Cura?

P.S. I've heard of two cases where Gmail decides my images are spam. Would appreciate feedback of any other cases please, to help me isolate cause.

Is there a better one that can still drive the printer over usb?  This is
a linux only farm.  And this is the appimage version of cura 4.9.1.
Among other bitches, it can't see a filename over 16 characters.

F5 shows trash all over, doesn't say why, f6 restores the rendered
preview.

Your changes fixed f5, but not cura. The first layer put down still shows
the error. And its continueing layer by layer, up to about 10 layers
now. And I am about to see if a ruby nozzle and carbon fiber PETG will
survive cleaning it up. PLA literally falls apart. No flexibility, and
this part WILL be flexed, about 2mm in a 52mm circle. The armature that
rotates inside it and drives it thru ball bearings is eliptical by 2mm.  
So this toothed belt and the outer bearing races are subject to being
flexed in and out about a mm each way, at up to 2000 rpms.

I edited the .scad to translate([0,0,6]) it all to be at or above the
plate, then found I was using the "CR-10S" driver when its a "CR-10S pro
V2", but V2 hasn't made it into cura yet so had to settle for a "CR-10S
Pro".
And I think it may be fixed. 2.5 hours will tell the tale. ;o)
But I expect to have switch to a carbon fiber filament for this part in
the long run. Might even have to buy a ruby nozzle smaller than the
default .4mm. That tale has yet to be written.

See my other post, Terrypin. I think its fixed, the problem never was
visible even in curas previews, only showing up on the build plate. It
was a combo of the wrong driver, and an stl that was vertically centered
with 6mm below the plate and 6mm above.
