I have just bought 2 Ender 3 Pros and am very pleased with them. On the Micro SD card that came with them there was a Creality Slicer that I am using and basically I have now printed over 70 items and never changed or got involved with a setting yet. I am using the Creality Slicer in its 'Quickprint mode' This slicer is a very robust older version of Cura but it seems to work so well.

I read so many things where people are messing with settings and spending money on Slicing programmes. For me this Creality Slicer is all I need and no need to know about settings. Just slice and print.

This is how it should be in my view
