Describe your issue:

I’m trying to get my bed to home on the Z axis, but it doesn’T work. The printer head centers above the bed, the bed lowers a few milimeters, and then I get this error message in the console window: Endstop z still triggered after retract.

I can get the probe to deploy/retract using the mcros on the dashboard in Mainsail. Tried using the Z endstop connection as well as different pin definitions, but I’m stuck.

Any help very appreciated!

Hello @Oblikfan !

You may have a probe installed, but the Z-axes still uns on endstop:

[stepper_z]
step_pin = PB0
dir_pin = !PC5
enable_pin = !PB1
microsteps = 16
rotation_distance = 8
endstop_pin = ^PC2  # <---------
position_endstop = 0.0
position_max = 250

Using a probe as endstop works a different way:

Thank for the reply.

reading the configuration reference file, I can’t figure out what pin to use for my endstop. If I try unsing one of the pins for the probe, I get an error message saying the pin is used twice in the .cfg file

It’s not a pin on the board:

The probe section also creates a virtual “probe:z_virtual_endstop” pin.

Ok, the virtual pin is setup and the bed tries to home, but it won’t stop when it reaches the probe.

Please attach a recent klippy.log to your next post.

Figured it out, the probe was sitting too high compared to my hotend nozzle.

Moved it down and now it homes ok.
