I am having a nightmare with the Z axis home switch. It's just getting that first layer printed and once I got it right, the next print is out, not a lot but getting very annoying.
My Z home switch is well secured and have a screw adjuster that works fine, I just don't think the micro switch is that accurate and was wondering if there is anything better?

G92 sets the position of the axis where it is, in other words G92 Z0. sets where the head is to Z0. If you use the method above and anything moves while the printer is off you have lost your position. It's generally a bad idea to rely on a printer holding position with power off, not to mention the issue of drivers only wanting to turn on with whole steps, so if your magic position is a few microsteps away from a full step, that can induce error as well.
To the OP what kind of homing speeds are you using? Too fast and you won't get good accuracy.
