Help with slicer and Elegoo Neptune 4 Pro

[WF55]

Hello,
does anyone have experience with Simplify3D and the Neptune4 Pro?
I can't manage to produce reasonable prints. I would like a printing speed of 150 - 200 mm/s.
I tested the Prusa slicer as a test. This gives me perfect prints.
Has anyone had a similar problem and a solution with S3D for me?

Thanks
Fred

Is your issue only that you want it to print faster, or is there some kind of other quality problem you encountered?

I want to print faster.
If I print faster (150 mm/s) I have much quality problems with infill.
Enclosed a picture with Prusa slicer with 200 mm/s and S3D with 150 mm/s , the same temperature.

Can you post the 2 gcode files? That will make it easier to give suggestions. It looks like you just need to increase the extrusion rate for the infill in S3D.

Attached the files.
Thank you for wanting to help me.

The main difference I saw is that the Prusa file was using 6000 mm/min (100 mm/s) for the infill, but you have S3D set to use 9000 mm/min (150 mm/s). I you want to compare the prints you should really be using the same speeds.

As you start moving faster, you usually have to increase the temperatures and potentially also the extrusion rate. Otherwise you will see the broken infill like in your photo. There's some other good suggestions here:

Thank you for the information. I'll try that.

I'll come back to the topic again.
Am I correct that the "Default Perimeter Speed" is equal to the "Infill Speed" ?

So S3D doesn't have a separate parameter for the "Infill Speed"? If the "Infill Speed" seems too high to me, I have to lower "Default Perimeter Speed" and possibly increase the other speeds?

[S3D-Jason]

Yes, the default printing speed is usually the same as the infill speed.
