Follow the steps in this tutorial to adjust the Z-axis offset on your LulzBot Mini. The height of the Z-axis offset influences print results, as the thickness level of the first layer is a crucial aspect to any print. This tutorial will help you adjust the thickness level of the first layer, improving print quality in the process.
Before beginning the tutorial, it's important to understand some context around how the Z-axis influences print quality.
When auto-leveling, the nozzle electrically probing the washers determines the 0 position on the Z-axis.
Visually you can see the bed is lower than the corner washers. The Z offset: -1.35 means the printer will start the first layer 1.35 mm below the top of the corner washers (the 0 position in the Z-axis).
A dirty nozzle can affect the accuracy of the electrical connection. Be sure to clean your nozzle with a NON CONDUCTIVE material such as a blue shop towel if needed.
Verify your LulzBot Mini is plugged into computer with power off.
