Slicing adds new surface in middle of hollow area

[problemchild]

I am attempting to build the Secret Heart Box, thing #39682 file Bse_side1.stl , attached. I have successfully build this on my UP! Plus and on my M2 with Creator 1.1.2. I also built this with Creator. The profile (SecretHeartABSRevA.fff) and the Gcode (Base1PrA.gcode) are attached. Although the build separated from the bed and did not complete, the preview looks fine.

In an attempt to improve adhesion, I modified the profile and resliced the model, files (Base1PrTestC.gcode, SecretHeartABSRevC.fff), attached.

Only the first three files have been uploaded. BB seems to be balking.

Having trouble attaching two gcode files

Is it similar to this: http://forum.simplify3d.com/viewtopic.php?f=9&t=65

My workaround was to import the stl file, add the build operation process, save it as a factory file, open the factory file and then prepare the g-code, it slices properly. If the stl is imported and prepared directly then the problem shows up.

Thanks, Karl.

Yes, my case looks like the same thing. I'll try using factory files. The strange thing is that the extra layer seemed to be result of a change in the profile that didn't have any bearing on the model geometry.

Question: your preview screen shots have many more colors than mine, which are mainly various shades of green with red for rapid moves. I've looked at the color selections in the Creator preferences and don't even see where my preview colors are coming from. How did you get the colors?

[Karl_Williams]

I think those were the default colors for release 1.0.6. They must have changed the color scheme after that.

My understanding is that the color indicates the speed of motion. If you change the extruding rate, you'll get a different color. It's so you can see what layers are put down slower or faster, like if you use different speeds for raft, infill, first couple layers, etc., etc.

Simplify3D can confirm or correct, but that's my impression from what I've read in other replies.

Thanks Karl and Dale.

pc,

Here's the quote from S3D regarding the colors in the previewer:

The color represents the printing speed of those segments. It's starting to look blueish because the software is automatically starting to slowdown the printing speed to help maintain adequate cooling for these regions. This is intentional and can significantly help to improve print quality. If you want to try printing with it disabled you can uncheck the "Adjust printing speed for layers below XXX seconds" option on the Cooling tab of your FFF settings.
UNQUOTE.

Since the quick moves with no extrusion (e.g., moving to another part of the print) are shown in red, and S3D said above that slowing makes it "bluish", I'm going to stick my neck out and guess that red is fastest extruder motion, then orange, yellow, green, cyan, along the rainbow to blue as the slowest.

I agree with others who have suggested that a "color key" (map legend) be available -- maybe a mouse-over of some corner in the previewer? -- that will pop up a legend with a bargraph of the speeds in mm/s or mm/min or whatever alongside a rainbow color bar.

Some have suggested being able to configure the preview colors, but I like being able to tell the speed from the color. Just need a key so I interpret the colors as numbers. For those who are red-green color blind (and even for me, with pink/gray colorblindness), perhaps it would also be good to have a the bargraph popup come up when you park the mouse pointer on a line in the previewer, with the bargraph having a pointer to the color and a numeric display of the speed at that point.

I know Clayton said 1.1.3 is well along, so maybe they could sneak it in for 1.1.4...

I went ahead and had this squeezed in for v1.1.3 It will include a color map relating the preview colors to the movement speed. The color range has also been reworked slightly to better illustrate minor speed changes.

Thanks, C. You always do a better job than what's asked.
