Awesome, thank you.

Hi! I've read somewhere that the pause_temperature has been implemented, but I've searched and I couldn't find any examples like the ones you've posted above. Could you please tell if this resume script is good to resume the temperature of the bed and the extruder to the previous temperature before pause the print?:

{% if pause_temperature.0 is not none %}
; wait for bed to reach the previous temperature
M190 S {{ pause_temperature.b }}
; wait for extruder to reach the previous temperature
M109 S{{ pause_temperature.0 }}

Was having lots of problems getting this to work -- the extruder would not extrude after resume. I spent an entire evening on print fails until I found the comment in this thread by @c3r63ru5 . There is an issue in using the commands above with GCODE produced by Slic3r because it uses relative, not absolute extruder settings. I changed the resume code to the following and it worked perfectly.

{% if pause_position.x is not none %}
; relative extruder
M83
; prime nozzle
G1 E-5 F4500
G1 E5 F4500
G1 E5 F4500
; absolute XYZ
G90
; move back to pause position XYZ
G1 X{{ pause_position.x }} Y{{ pause_position.y }} Z{{ pause_position.z }} F4500
; reset to feed rate before pause if available
{% if pause_position.f is not none %}G1 F{{ pause_position.f }}{% endif %}
{% endif %}

Thanks you for everyone.

I've followed the entire process and sensor works fine when filament runs out but when I change the filament and press knob for resume print process hotend comes back to correct position for a second then quickly return to change filament position and extruder retract filament again... substantially I'm in a change filament loop!!! Why this happens??
