Variable Heat-Soak

[airbornetrooper82573]

I saw on the voron discord someone making a variable heat-soak. Basically, if you cancel a print and restart if fairly quick, it avoids having to wait for the soak for as long.

Heatsoak here

Check if heat-soaking is needed

{% if current_bed < target_bed - 20 %}
    M118 Bed is cold.    # display message
    SET_DISPLAY_TEXT MSG="Heating Bed: {target_bed}c"
    M190 S{target_bed}      # Set bed temperature and wait until it is reached
    M118 Heat Soak 5 minutes    # display message
    G4 P{ 5 * 60 * 1000 }       # dwell = 5  minutes
{% elif current_bed < target_bed - 10 %}
    M118 Bed is warm.    # display message
    SET_DISPLAY_TEXT MSG="Heating Bed: {target_bed}c"
    M190 S{target_bed}      # Set bed temperature and wait until it is reached
    M118 Heat Soak 1 minute    # display message
    G4 P{ 1 * 60 * 1000 }       # dwell = 1 minute
{% else %}
    M118 Already Hot! Heat Soak 5 seconds    # display message
    SET_DISPLAY_TEXT MSG="Heating Bed: {target_bed}c"
    M190 S{target_bed}      # Set bed temperature and wait until it is reached
    G4 P{  5 * 1000 }       # dwell = 5 seconds
{% endif %}

End Heatsoak section

I tried adding this into my print_start macro but got Error evaluating 'gcode_macro PRINT_START:gcode': jinja2.exceptions.UndefinedError: 'current_bed' is undefined.

Would you be able to assist with incorporating something like this into the print_start? I already use your setup and just want to integrate if possible. Thank you

This is a bit out-of-scope for this macro, but feel free to do a fork and add your own twist and take on the macro.
