I use 9999 bottom layers when I want a solid part. I find it works better than infill.

your build plate is too far from the nozzle. Decrease the starting Z height - you can do that with the G-Code Z offset in S3d, but there should be a hardware adjustment on your printer as well.

Is the part building correctly? It appears to have internal ribs in the image with the weight spec, but yours looks to be built solid with top and bottom layers, perhaps filled with infill. S3D will give you a weight estimate when you PREPARE TO PRINT. What happens if you set the print up with ZERO ...

I ran some parts last night on my Raise 3D N2+ with an aftermarket Bondtech extruder. Looking up ABS density it ranges from 1.06-1.08 g/cc. If I enter the density as 1.07 the predicted weight for the print is 314.8. With a density of 1.08 the predicted weight for the print is 317.7 Measured weight i...

One thing I did was to "drill" some very small holes through the area that I wanted filled in. I don't recall the size, but maybe .004". Going too small caused issues with the STL file. S3D then drew perimeters around all the little holes, so by matching the hole spacing to the total perimeter X2 I ...

If you are wanting to dial in dimensions on your machine to get more accurate parts, I have a procedure I've used very successfully. You can find it in this thread. Note that there are newer files posted in the last post. https://forum.simplify3d.com/viewtopic.php?f=9&t=6130&p=26646 If you are needi...

I've generally had to try a few tools when repairing a big file. I haven't found one tool that works great on everything.

Make sure the DENSITY of the filament you are using is set correctly. When I've checked part weight predictions they've been spot on. That calculation is a cake walk compared to print time.

I would love to see accel and jerk settings for different build features and moves integrated in to the UI.

No, modeled in inches. Thus the 2540 scale factor. The minor adjustments on the X and Y scale are calculated to account for machine and material behavior resulting in dimensionally accurate parts.
