Klipper Configuration

Example Configuration File

Below is the recommended configuration file content. Please adjust according to actual needs:

tip

• If you need to use the ALPS pressure module as a Z-axis endstop, please refer to the configuration below

[stepper_z]
endstop_pin: probe:z_virtual_endstop
# position_endstop: -0.5
