I'm from Germany and new to this forum.
I'm having a strange issue printing a lampshade in vasemode/spiralize (Cura 2.5.0), always got a HUGE Spiral around. (printer CR10)
At this time I've printed it three times. (its always the same spiral but getting from print to print less heavy and flat/smaller?!)(the 1cm big wobbles, its a perfect spiral around from bottom to top.)
Retraction on, Fans on, Zhop on, layerhigh 0.2mm, wallthickness 0.4 (nozzle is 0.4)
-> z-seam and a huge spiral around the whole print (startet at 5cm)
retraction off, fans off, zhop off, layerhigh 0.2, wallthickness 0.4 , 70mm/s
-> no seam, but also a spiral around, this time the spiral startet later (startet at 8-10cm)
retraction off, zhop off, fans off, layerhigh 0.2, wallthickness 0.7, 70mm/s
-> looked great but turned out the same, spiral startet waaay later (at 15cm)
(first at the back -> newest in the front)
Now I have one lampshade left, because I needed 4 of them mofos
First we thought the spiral comes from the fans, but fans off turned out the same :/
Thicker walls looked good at the beginning but the spiral started later.
Maybe its because the print is so huge (290mm width) and the weight pushes down?
Or the Filament is to warm+weight = spiral? maybe 30% fan speed on?!
Every other print before turned out great, no problems.
Btw. this is the first time I printed something in Vase mode.
