    Steps for configuring a new extruder onto a TapChanger v0.2.5
Step 0. Before starting


Re-tighten your carriage screws, this can be a cause of non-repeatable homing.
If you use sensorless homing: make sure there is no occasional skipping while either axis are being homed! This may cause misalignment. If that is the case, lower the homing_speed in your printer's [stepper_x]/[stepper_y] configs.
Check your homing routine, ensure it homes Y before X, otherwise you may accidentally bump into docked tools, or you may get interference from the Y tensionner if you home X too close to the front of the printer.

Step 1. Manually swap to new extruder
