Fix Inconsistent Layer Time

Howdy my happy printers,

As you can see from the screenshot below, the layer time across the print is inconsistent which is causing the print to look a little ugly. it’s not the worst but I’d like to improve it. You can see my speed settings in the picture too. Please advise what else I can try.

There are different parameters which affect layer time.
As you stated the printing speeds, but you also need to consider the parameter within the filament settings, i.e., Auto Cooling in Filament Settings | Bambu Lab Wiki.
As well as the volumetric flow rate:

With the proper combination of these settings, one can achieve uniform or near-uniform layer time; however, there are limits, so you may need to speed down the faster layers.

To try to help, can you clarify the need or goal for the changes you add in speed settings. Can you share the specs for the PA filament you are using?

I’ll clarify best I can.
The material is Matter Hackers Pro Nylon. The part I’m printing is being sold and used outdoors and is expected to be abused. Red is needed thus the Pro Nylon which has a strong layer bond.
This is the link to the store page which has the TDS download: Pro Nylon

I’m just trying to get the Outer Wall to be as clean as possible because this is being sold.
