Good news and Bad news: the good news is I was able to print (almost) the ribbed vase I was having trouble slicing. To get it to slice I doubled the bottom's thickness from 3.1 mm to 6.2 mm. And when I printed the part I scaled it up from 110 mm high to 120 mm high.
With these changes Kisslicer seemed to slice it OK. However, Craftware still would not slice it properly. So I used Kisslicer's GCode to start printing. The estimated total print time was a little under 14 hours.
The print looked absolutely superb up to the time I went to sleep for the night. You can see how smooth the inside and outside surfaces are in the first image below. Without a doubt this is the highest quality I have printed so far. Setting Layer Height = 0.2 mm might be the key to that. I was hoping for a really great finished part when I got up the nest morning.
Unfortunately this was not the case. When I got up and turned on the light (it was just before 5AM) the printer was at about the 90% mark and doing just fine. I turned on my PC to get ready to post this message, and very shortly after that the printer stopped printing. I looked at the LCD and it had gone back to the main Info screen where it showed 0 for the heated temperature and the actual temperature dropping fast. So I had no choice but to stop the print and do an Auto-Home.
The printer is powered from the same power control center as my PC. This unit has 4 independently switchable power outlets and is itself connected to a UPS box. My guess is that there was a slight voltage drop caused by turning on my PC, and this somehow affected the Atom2's circuits.
After I did Auto-Home I checked the motherboard connection of the 2 yellow thermistor wires and that was fine. Then I tried Preheat to 200 and that worked OK. So I do think the printer is physically OK.
The second photo below shows the other problem I had: The bottom came off the part when I tried removing it from the print bed. In fact, the bottom did not print as designed - most likely as a result of what Andrew Lee discovered when he looked at the part's STL file. The bottom was supposed to be 6.2 mm thick, but in fact it printed a bottom only 0.6 mm thick (0.6 mm = 3 times 0.2mm layer thickness).
Even though this print failed I am very pleasantly surprised at the quality the Atom2 is capable of printing. I am going to change the way the bottom surfaces are created and try this print again - probably in a smaller version first. Hopefully that will yield an even more impressive result.

this makes me curious. Try send me the file. I would love to look at in my 3d setup. I think you have more than one surface in the buttom.

Andre - I'm sorry but I have deleted the STL file and have only the GCode left - so we will never know what actually happened. However, I have just finished re-defining how the part is made and I now have the inside surface joined with only the insid

Andre - I forgot that I had saved the STL file from the part you looked at on a cloud drive. I also put up there my "fixed" version of the part Here is the URL for both. The fixed one is called thermos.stl:

Finished slice this thermos.stl on Kisslicer 1.5 Beta 2.2
Peak memory usage is about 3.5GB
bottom is about 6.2mm

Hi Clarence. I have the same version of Kisslicer as you do, and when I sliced thermos.stl I get strange results. My key parameters are 0.2mm layer thickness, Num loops = 3, Extrusion width = 0.38, Skin Thickness = 2 mm, and Infill = Vase.
Here are th

Why infill vase or hollow? I think slicer did them right. But for this stl, it should be infill at least 10? Check the start of my gcode, you can found the slicer setting there for reference.

Clarence = thanks for your comments. Because I started designing models before I ever got a printer I had to guess how to do it. At the time it seemed to me that a vase or bowl type part should have an inside and an outside so it would have sufficient
