new to 3D printing, help please

[DaleSabers]

When I say it's not consistent for a border test, I mean it's not consistent. If I tell it to reduce the height, it doesn't reduce or it will reduce just not the amount I'm wanting. The bed is level as I've taken a digital and torpedo level to both surface and bed. I'm hearing some clicking when it goes over the prints but the company says it's normal to hear it according to the users guide. So it's likely hitting the prints but since I can't get the calibration to be consistent.

I've managed to get a batarang from batman beyond printed but the material curls from the bed just ever so slightly. I'm doing up a small print right now and will post pictures of everything once it's done.
