Hi,
We recently acquired an Ultimaker and are having difficulty printing out a model that is a logo with a loop at the top for a chain to go through (like on a necklace). The original STL file has been designed so that the loop is the same height (on z axis) as top and bottom of logo body (to avoid any support structure being necessary). There is enough base in the loop to build the curve without support (and we've seen other similar STL files and models work this way.
Our problem is that even after 4,267 tweaks to Cura to the best of our ability, the Gcode files result in a print that is printing extra lines between the logo and filling the loop with material, even though we have support structure turned off. We don't seem to see the lines on the print result.
We're not sure if the gcode is causing the lines and fill or another setting in Cura is causing the Ultimaker to drop the xtra material, although with our experience it looks more like support structure is being built as the extra lines look like support lines and not printing errors.
We are in a hurry to get a ton of these printed so we are willing to hire someone with experience to take a look at the source STL and the Gcode and either help us fix the code or send good code based on the STL from any slicer they prefer...
Hope to hear from someone, and thank you!
