1st layer issue
Hi, this is my first proper 3D printer. Took me like 3 days to set up lol but I'm having issues with the first layer for some reason. I've re calibrated it using the wizard 3 times now and it seem adjusting it live whilst printing doesn't seem to help either. Any advice would be great. Thanks 
RE: 1st layer issue
It looks like its not extruding the filament properly. A good place to start would be to check the filament feed. If you can hear clicking noises then the adjuster is too tight otherwise it might be too slack. Have a look at this video it shows how to set it:
If its not that then post anything further, if it improves then also have a look at this thread:

Fine tuning the Live-Z by printing a square is easier to see and will help you get it dialled in.

Ahh! I do actually hear clicking. I wondered what that was. Sooo thanks for that I will take a look at the video. Hopefully I don't tighten or loosen the wrong thing lol
RE: 1st layer issue
Corners need to be 90 degrees, if not possible to high.
Square at end , lines are not sticking together, there should be no holes.
Check filament and temperature filament is correct, if yes is correct do 10 degrees more heat on nozzle and see if extruding works.
It could be under extruding, check spring setting, see manual for this.
Clicking sound is not good, wrong filament, spring not good adjusted, grub screw loose om gear, check if filament path is good.
