Tiny Z seam in spiral mode #809

Open flouSH opened 10 years ago

flouSH commented 10 years ago

Hey David,

there's a bug in the spiralize function which leads to a very subtle z seam. I've seen it before, but never looked into it. Now Roland from Repetier gave me a hint to look at the gcode via Repetier host.

In there you can easily see it (tiny white line): image

Looking closer at just one of those spots and the corresponding gcode* you quickly see that there's a rapid move to close a gap in the spiralized code: image

Is there any chance you can fix this? It just so super sad - because with a high-end printer like the Ultimaker you can still see the Z seam, even when spiralized - which somehow destroys the whole purpose of spiral/Joris.

Or is it my mistake and I misunderstood something?

See you soon at FabCon 2014! Florian

I noticed this too, and I wonder if it's related to the very odd spacing in the infill of the bottom of vaze when running vaze mode. In normal mode the bottom fill is fine.
