How to Correct the Z-Offset on Your Ender 3, Ender 3 V2 and Ender 3 Pro
Unless you're using BLTouch on your Ender 3, then you'll need to have your Ender 3, Ender 3 V2, or Ender 3 Pro's print bed on a proper Z-axis to manually level the bed.
This is a known issue with the Ender 3-series of 3D printers.
If you've noticed that you can't get your Ender 3's print bed low enough to properly level (which was my case), then you're likely facing the issue of an improper Z-offset, which is another way of saying that your printer's extruder is improperly aligned along the Z-axis of your printer.
What does the Z-axis limiter switch do?
The Z-axis limiter switch tells the printer where the z-axis begins on your 3D printer. When you auto-home your Ender 3, the extruder base moves down until it runs into the Z-axis limiter switch, telling it to stop moving down. This protects your print bed. But if it's improperly aligned, whether too high or too low, then you'll struggle to get your print bed leveled properly for printing.
The good news is that it's quite easy to adjust the Z-offset on the Ender 3, Ender 3 V2, and Ender 3 Pro. We'll show you how!
