I want Advice on Optimizing 3D Printing Settings for Better Quality

Hello everyone,

I am working on improving the quality of my 3D prints and would love to get some advice from the community; I have been using my 3D printer for a while but i have noticed that some prints do not come out as expected issues like stringing, poor layer adhesion,
& inconsistent surface finishes.

I primarily use PLA and PETG filaments but I am open to experimenting with other materials if they offer better results. What are some optimal settings for print speed, temperature & layer height that you recommend?

Also i have upgrading my printers hardware, such as the hotend or the build plate. Would you suggest any upgrades that could lead to significant improvements in print quality?

As well, I found these resources when doing research on this; https://marlin.crc.id.au/forum/t/cannot-recover-from-pausing-a-3d-printpower apps & if anyone have any resources, tutorials or personal experiences please share with me, It would be greatly appreciated!!

Thank you :slight_smile:
