For setting Z0, I've been putting a sheet of 80gsm paper under the nozzle at printing temperature and dropping the head until I can just feel resistance. If I then drop it a further 0.05mm I can still PUSH the paper with resistance but starting to feel a vibration. If I drop it a further 0.05mm I can then only PULL the paper to get it to move, not push it and feel a lot of vibration.
Assuming the right answer if one of those three to set Z0 which do people use?
Secondly against your Z0 calibration method what first layer height do you use if you have a 0.5mm nozzle?

Use a 0.004" or 0.104 mm feeler gauge as your zero point. That way your nozzle won't drag across your plate when you home and then disable steppers to pull your print out. If your first layer is .2 or .3 mm and you set your first layer extrusion at 150%, you'll get a nice well-adhered first layer AND you don't have to fool around with all the Z offset BS. The feeler gauge is stiff enough to easily slide in the gap and get a good feel for whether it's right or not. Paper is, like someone said, too subjective. Go to the auto store or Harbor Freight and get a feeler gauge set and be done with it.
