New to 3D Printing - Creality Ender 5 Plus

[loadedphp]

Hi Fellow PrintersI am new to 3D printing and got myself a Creality Ender 5 Plus due to its volume size, and good reviews.Currently I still have not been able to print my first model due to the distance between the nozzle and the print bed, and have some questions which if I can find the answers I hope to get my printer going:Current problem seems to be that the print bed leveling:So my questions are:1)How far away should the print nozzle be from the bed for PLA?2)The BL touch when doing a auto bed leveling always levels the bed with a 2 mm gap from the nozzle, is there any way to fix that?Any other suggestions to help a beginner get started.
