ABL(Auto Bed Leveling) & Z-offset adjustment

ABL?

For 3D printing, it’s essential to make sure your bed is level before starting any print. An unlevel bed often results in print quality issues, like warping or completely ruined prints, which means wasted material and time.

On most consumer-grade 3D printers, leveling your print bed involves rotating a few (usually four, one for each corner) screw knobs to raise or lower the bed incrementally at different points. This process can be tedious and inexact, but there’s an automatic answer! Auto-bed leveling (ABL) is an excellent feature for 3D printers that can very accurately level your bed with almost no manual effort.

Z-offset?

Z offset is an important 3D printer setting that allows users to perfect their first layer while working with different materials and build surfaces. Z offset can be adjusted in slicer software or by inputting G-code commands.
