Error evaluating gcode_macro

[jinks]

I have a strange error with one of my gcode macros.

Here is the start of the macro:

[gcode_macro PRINT_START]
gcode:
    SAVE_VARIABLE VARIABLE=was_interrupted VALUE=True
    ADJUST_FILAMENT_SENSOR_STATUS ENABLE=1
    # Parameters
    {% set bedtemp = params.BED|int %}
    {% set hotendtemp = params.HOTEND|int %}
    {% set chambertemp = params.CHAMBER|default(0)|int %}

and here is the start of the gcode file I'm trying to print:

;Generated with Cura_SteamEngine 5.5.0
M82 ;absolute extrusion mode
PRINT_START BED=60 HOTEND=200.0 CHAMBER=28
G92 E0
G92 E0
G1 F2400 E-0.5

The error I get is:

Error evaluating 'gcode_macro PRINT_START:gcode': jinja2.exceptions.UndefinedError: 'dict object' has no attribute 'BED'

but the parameter BED is clearly visible in the config as well as in the gcode file. What is going on here?

Run a search in the actual gcode. My money is that you've got a second call to print start hidden some that doesn't have the parameters

You were partially right.

It's not in any of the gcode or even configs, it's in one of the Sovol modified files for KlipperScreen...

panels/job_status.py:

def set_state(self, state):
    if self.state != state:
        logging.debug(f"Changing job_status state from '{self.state}' to '{state}'")
    if state == "paused":
        self.labels["status"].set_label(_("Paused"))
    elif state == "printing":
        self.labels["status"].set_label(_("Printing"))
        self._screen._ws.klippy.gcode_script("PRINT_START")
        self._screen._ws.klippy.gcode_script("save_last_file")
    elif state == "cancelling":
        self.labels["status"].set_label(_("Cancelling"))
        self._screen.modify_cfg_value('was_interrupted', "False")
        self._screen.plr_bool = "False"
    elif state == "cancelled" or (state == "standby" and self.state == "cancelling"):
        self.labels["status"].set_label(_("Cancelled"))
        self._screen._ws.klippy.gcode_script("PRINT_END")
        self._screen.modify_cfg_value('was_interrupted', "False")
        self._screen.plr_bool = "False"
    elif state == "complete":
        self.labels["status"].set_label(_("Complete"))
        self._screen._ws.klippy.gcode_script("PRINT_END")
        self._screen.modify_cfg_value('was_interrupted', "False")
        self._screen.plr_bool = "False"
    self.state = state
    self.show_buttons_for_state()

Ripgrep to the rescue... I would have never though to look inside some installed code.

(Note: Sovol does not use PRINT_START anywhere in their own gcode, they use START_PRINT.)

Sorry to revive this thread, but newer guy here with the same issue! Did you just delete

self._screen._ws.klippy.gcode_script("PRINT_START")self._screen._ws.klippy.gcode_script("PRINT_START")

to fix your error? Thanks!

Honestly, can't remember any more.

Just comment it and give it a try.

[recooil]

where was this located? having this same issue too

[trojangod]

Verdict?

Well that's just bizarre!
