Adding parameters to END_PRINT

Hi folks, just don´t want to change the END_PRINT macro or pull it out and add it to an own cfg. I really would like to move z to a defined hight like 200 before the motors are switched off. Further more, I would really like to ad a call for a special gcode at the end of the END_PRINT: This gcode will wait until the heaters are cooled down and then shut down Klipper and after some waiting time it calls my Tasmota to switch off. What should I do to get this working from your perspective?

Look at the various built in variables and hooks you can override https://os.ratrig.com/docs/configuration/macros

Configuring RatOS Macros | RatOS

RatOS comes with a bunch of flexible predefined macro's that can be customized via variables and macro hooks.

So far okay, I got that. Nevertheless wouldn´t it be nice to have this as a variable in the printer.cfg, as it is for the printhead: variable_end_print_park_in: "back" like: variable_end_print_z_park_in: 200 Other than that... There is a macro hook called: _USER_END_FEATURE When is this hook called? Is it used at all? I know... If you have something printed which is higher than 200, you would run into an issue. So this needs to get calculated from the current hight. Okay, so let´s forget about the _USER_END_PRINT_AFTER_HEATERS_OFF hook. But I still would like to have at least the possibility to call some gcode after the print is ready and the END_PRINT is done. Couldn´t we get added the _USER_END_FEATURE at the end of the END_PRINT? As long it is empty nothing would happen, but the user would be able to add something instead of just manually run an additional gcode afterwards... @Helge Keck is this something one could think of?

use _USER_END_PRINT_PARK macro to set your z height and for the rest jsut create another macro and put it after END_PRINT in your slicer and you are done

blacksmithforlife•3mo ago

yeah - like what I do https://github.com/jscancella/myKlipperFiles/blob/main/vcore3-printer.cfg#L309-L322

Okay, that´s the other way round... but that is some solution at least. Thanks guys... didn´t think about using the slicer for that.

You can supply any parameter you want to END_PRINT, they will be passed down to the _USER hooks. For example

END_PRINT mycustomvariable="center"

END_PRINT mycustomvariable="center"

printer.cfg

[gcode_macro _USER_END_PRINT_PARK]
gcode:
  M118 Park in {mycustomvariable}

[gcode_macro _USER_END_PRINT_PARK]
gcode:
  M118 Park in {mycustomvariable}

Will print Park in center before END_PRINT calls _END_PRINT_PARK to park the print head. If you want to change the behavior of the endprint parking, i would override _END_PRINT_PARK specifically. If it's dependent on parameters, override _END_PRINT_PARK with a blank gcode parameter, and handle all the logic in _USER_END_PRINT_PARK.

I´m still waiting for my heater for the hotend so could not test yet. I just added this to my own_macros.cfg which is included in the printer.cfg: [gcode_macro _USER_END_PRINT_PARK] gcode: G1 z 300

miklschmidt•3mo ago

That'll do 👍

Well... so far so good, but I do have still an issue with the END_PRINT. If I call my script to shut down printer and stuff after the print is ready with this macro:

[gcode_macro POWER_OFF_PRINTER_NOW]
gcode:
  {% if printer.extruder.temperature < 49 %}
    RESPOND MSG="Printer switch-off..."
    G4 P6000
    host_shutdown # Calls safe shut down of Raspbi
    tasmota_off # Calls Shell command to switch off Tasmota
  {% else %}  
    RESPOND MSG="Waiting for cooling down to shut off."
    TEMPERATURE_WAIT SENSOR=extruder MAXIMUM=49
    G4 P6000
    host_shutdown # Calls safe shut down of Raspbi
    tasmota_off # Calls Shell command to switch off Tasmota
  {% endif %}

[gcode_macro POWER_OFF_PRINTER_NOW]
gcode:
  {% if printer.extruder.temperature < 49 %}
    RESPOND MSG="Printer switch-off..."
    G4 P6000
    host_shutdown # Calls safe shut down of Raspbi
    tasmota_off # Calls Shell command to switch off Tasmota
  {% else %}  
    RESPOND MSG="Waiting for cooling down to shut off."
    TEMPERATURE_WAIT SENSOR=extruder MAXIMUM=49
    G4 P6000
    host_shutdown # Calls safe shut down of Raspbi
    tasmota_off # Calls Shell command to switch off Tasmota
  {% endif %}

which is called in Orca after the END_PRINT as seen in my screenshot, the print does never reach 100%. It get stuck at 99% and the print is saved as error. Installed is v2.1.0-RC2-109-g975b128f Any idea how to wait for print finish (100%) to make sure all things are done?

try it with a delayed gcode macro should do the trick

[delayed_gcode POWER_OFF_PRINTER_NOW]
gcode:
  {% if printer.extruder.temperature < 49 %}
    RESPOND MSG="Printer switch-off..."
    G4 P6000
    host_shutdown # Calls safe shut down of Raspbi
    tasmota_off # Calls Shell command to switch off Tasmota
  {% else %}  
    RESPOND MSG="Waiting for cooling down to shut off."
    TEMPERATURE_WAIT SENSOR=extruder MAXIMUM=49
    G4 P6000
    host_shutdown # Calls safe shut down of Raspbi
    tasmota_off # Calls Shell command to switch off Tasmota
  {% endif %}

[delayed_gcode POWER_OFF_PRINTER_NOW]
gcode:
  {% if printer.extruder.temperature < 49 %}
    RESPOND MSG="Printer switch-off..."
    G4 P6000
    host_shutdown # Calls safe shut down of Raspbi
    tasmota_off # Calls Shell command to switch off Tasmota
  {% else %}  
    RESPOND MSG="Waiting for cooling down to shut off."
    TEMPERATURE_WAIT SENSOR=extruder MAXIMUM=49
    G4 P6000
    host_shutdown # Calls safe shut down of Raspbi
    tasmota_off # Calls Shell command to switch off Tasmota
  {% endif %}

and after END_PRINT in the slicer you call it with

UPDATE_DELAYED_GCODE ID=POWER_OFF_PRINTER_NOW DURATION=1

UPDATE_DELAYED_GCODE ID=POWER_OFF_PRINTER_NOW DURATION=1

I´ll give it a try today. Thanks for the hint. OKay, I edited my macros now like this:

Update: That did the trick, thanks mate. I just had to add "CHAMBER_HEATER_OFF" after "gcode:" because the chamber heater kept heating for any reason. After that I had no issues.
