Hello,

Basic Information:

Printer Model: Ender 5 pro
MCU / Printerboard: BTT mini E3 V2

Describe your issue:

I Have a Print end macro like this:

[gcode_macro PRINT_END]
#   Use PRINT_END for the slicer ending script - please customize for your slicer of choice
gcode:
    M400                 ; wait for buffer to clear
    G91                  ; Relative positioning
    G1 E-2 F2700         ; Retract a bit
    G1 E-2 Z0.2 F2400    ; Retract and raise Z
    G1 X5 Y5 F3000       ; Wipe out
    G1 Z10               ; Raise Z more
    G28 X0 Y0            ; Present print
    G90                  ; Absolute positioning
    SFS_DISABLE          ; disable smart filament sensor
    M106 S0              ; Turn-off fan
    M104 S0              ; Turn-off hotend
    M140 S0              ; Turn-off bed
    M84 X Y E            ; Disable all steppers but Z

…At the end off the print I have this Error "!! Must home axis first: 0.000 0.000 0.200 [0.000]
The print is good only this error, The nozzle

Before I have that print end in my Cura Slicer Printer’s settings and I have no problem.
Can you help?
Thanks
Pat

Hello @Pbonamy !

In the klippy.log there is more:

[gcode_macro PRINT_END]
gcode = 
	M400                 ; wait for buffer to clear
	G91                  ; Relative positioning
	G1 E-2 F2700         ; Retract a bit
	G1 E-2 Z0.2 F2400    ; Retract and raise Z
	G1 X5 Y5 F3000       ; Wipe out
	G1 Z10               ; Raise Z more
	G28 X0 Y0            ; Present print
	G90                  ; Absolute positioning
	SFS_DISABLE          ; disable smart filament sensor
	M106 S0              ; Turn-off fan
	M104 S0              ; Turn-off hotend
	M140 S0              ; Turn-off bed
	M84 X Y E            ; Disable all steppers but Z        # <-----------
	{% set max_x = printer.configfile.config["stepper_x"]["position_max"]|float %}
	{% set max_y = printer.configfile.config["stepper_y"]["position_max"]|float %}
	{% set max_z = printer.configfile.config["stepper_z"]["position_max"]|float %}
	{% if printer.toolhead.position.x < (max_x - 20) %}
	{% set x_safe = 20.0 %}
	{% else %}
	{% set x_safe = -20.0 %}
	{% endif %}
	{% if printer.toolhead.position.y < (max_y - 20) %}
	{% set y_safe = 20.0 %}
	{% else %}
	{% set y_safe = -20.0 %}
	{% endif %}
	{% if printer.toolhead.position.z < (max_z - 2) %}
	{% set z_safe = 2.0 %}
	{% else %}
	{% set z_safe = max_z - printer.toolhead.position.z %}
	{% endif %}
	G0 Z{z_safe} F3600             ; move nozzle up
	G0 X{x_safe} Y{y_safe} F20000  ; move nozzle to remove stringing
	TURN_OFF_HEATERS
	M107                           ; turn off fan
	G90                            ; absolute positioning
	G0 X60 Y{max_y} F3600          ; park nozzle at rear

Can you imagine what this line does?

After disabling the motors you always have to home before doing any move.

Hello EddyMI3D,
Now end print is OK, I have just to adapt to my printer for parking the nozzle in front, particularly of my Ender 5 pro, front and rear are inverted.
Thank for your help.
Have a great day.
Pat
