Homing the pipette head

About this topic

This topic describes when and how to home the pipette head.

About homing

The pipette head has a defined home position for each axis of motion. Homing sends the pipette head to the home position for the axes. Home the pipette head to reset the axes. For example, if you notice the Bravo Platform is not moving to locations or teachpoints accurately, home the pipette head.

Homing the pipette head is typically done automatically on first initialization after startup.

There are four homing axes.

WARNING

Keep away from the Bravo Platform when the pipette head is moving or about to move, especially in the z-axis direction. The pipette head might not stop immediately in a collision and a pipette tip could pierce your hand.

To home the pipette head:

1

In

Bravo Diagnostics, click the Jog/Teach tab.

2

To home the pipette head for all axes, click

Home XYZ.

The pipette head moves to the home position.

The axis order of homing is z—> x—> y.

Note: To home the pipette head in a single axis, click

Home [ axis]. Make sure you home the z- axis first so that the pipette head avoids the labware.
