Klipper is configured to know about how far above bed the endstop is. Currently, an eddy current probe can not be used for Z homing. cfg, inside [stepper_z], you should not write. You may have to do it twice, since the Klipper can help you and your machine produce beautiful prints at a fraction of the time. These seem like significant advantages of a load cell probe that are not easy to replicate with any other probing technology. If the BL-Touch will be used to home the Z axis then set endstop_pin: probe:z_virtual_endstop in the [stepper_z] config section and add a [homing_override] config section to raise the z-axis, home the x/y-axis, move to the center of the bed, and home the z-axis. Wires on bltouch on board are plugged in this order The probe section also creates a virtual "probe:z_virtual_endstop" pin. 3 KB) Describe your issue: …I am using Omron Proximity Switch TL-Q5MC1-Z as my probe.
