ERCF in pause and start_print.cfg about klippain HOT 2 CLOSED

Hello,

As I don't have an ERCF myself at the moment it's quite hard for me to work on that now.
However, @elpopo-eng, do you have any insights about this issue ?

from klippain.

my temporary solution is to use the toolhead sensor to stop the macro in case of non detection of filament at the end of loading:
After:
ERCF_CHANGE_TOOL_STANDALONE TOOL={INITIAL_TOOL}
I make a call of _DO_ERROR_TOOLHEAD_SENSOR_EMPTY

[gcode_macro _DO_ERROR_TOOLHEAD_SENSOR_EMPTY]
gcode:
{% if printer['filament_switch_sensor toolhead_sensor'].filament_detected != True %}
{action_raise_error("ERROR ERCF !!! UNLOCK ERCF FIRST and restart start_print macro.")}
{% endif %}

That works fine, but need to have a toolhead sensor!!!
