Basic Information:
Printer Model: RatRig V-Core 3.1 500
MCU / Printerboard: Octopus 1.1
I use the BTT smart filament runout and jam sensor. If I use the standard M600 macro and change the spool / load new filament, the sensor keeps triggering on “resume” instantly.
Workaround: I disable the sensor manually while loading the new spool and resume with the sensor disabled. then once le print is running for a layer or two I re-enable it - and the printer keeps printing.
Did someone solve this with a better M600 implementation or so?
Thanks!
this is the current M600 macro I use:
[gcode_macro M600]
description: Executes a filament or color change by pausing the printer letting you cut the old spool - purge and reload new filament.
gcode:
PAUSE
##UNLOAD_FILAMENT
PURGE_FILAMENT
M117 Bitte neues Filament mit guter Spitze einsetzen.
RESPOND MSG=“Bitte neues Filament mit guter Spitze einsetzen.”
LOAD_FILAMENT
[gcode_macro PURGE_FILAMENT]
description: Purges cut filament
gcode:
SAVE_GCODE_STATE NAME=unload_state
G91
{% if params.TEMP is defined or printer.extruder.can_extrude|lower == ‘false’ %}

# Heat up hotend to provided temp or 220 as default as that should work OK with most filaments.
M104 S{params.TEMP|default(220, true)}
TEMPERATURE_WAIT SENSOR=extruder MINIMUM={params.TEMP|default(220, true)}
{% endif %}
{% set unload_speed = printer[“gcode_macro RatOS”].filament_unload_speed|float * 60 %}
{% set unload_length = printer[“gcode_macro RatOS”].filament_unload_length|float %}

Macro LoadFilament is practically the same with different speeds as purge
