New to printing and just got a tronxy xy-3. Having a few problems getting it dialed in. It's printing roughly 10 mm above the bed...sometimes. I'm not sure what I need to change but sometimes it will print above the bed and sometimes it will come down to where it should be. I have printed a few things...when it gets down to the bed. And they come out decent for now. If i move the Z axis and then try and print, It asks if i want to print from the current location. I'm using cura to slice. We 3D print where I work so I have a general idea of how to set the settings and how it should be printing.
