Another Settings(s?) Problem with My 3.2.1

[danilo 0]

 Have a decent set of STL files on hand  Trying to print them from a Cura Slice and the print messes .

Extruder action is  smooth then in mid circle it Jerks and returns to the begining of the segment  , missing bits and  seemingly of a mind of it's own Can't seem to convince it to laydown a simple continous bead.

Which to MY mind it should do automatically on a Simple half circle??.  What's up with the  jerk then stop in the middle action?

Printer has been doing 'jes fine'  on previous other prints (today) so a Hardware fault is seeming  as improbable cause.

Do I have a setting (s) bungled    OR??

Can someone lookit this .stl and Cura Gcode.. (Gcode is V small) to see if there is anything obvious

Cylinder half 1.stl

AA6_Cylinder half 1.gcode

It looks to me that you have the z-seam location to either random or possibly nearest with the corner preference set to something other than none.

 

BTW, that model is not going to be printable when orientated vertically because the fins have no support. It would be printable orientated like this:

Thank you..   note that I'm reducing the scale by 2/3rds ,  that changes the goal posts.

Fixed it by fiddling with wall thickness

At smaller size..it  Only prints well when vertical. Horizontal Layering produces poor  fins... even at finest settings
