today I found the mainsail-config when searching why I can't edit the mainsail.cfg.....

as there is also a M600 i tried to modfy my unload Filament macro to work together with the PAUSE from there, they use the 'printer.extruder.can_extrude' to check if the hotend temp is high enough to extrude. as I need it the other way around to heat up if required I thought I could use this instead 

{% set hotendtemp = params.HOTEND|default(230)|int %}
{% if printer.extruder.temperature < '210' %}
      M117 Heating...
      STATUS_HEATING
      M109 S{hotendtemp}                                                  
{% endif %}

so my M600 is only 

[gcode_macro M600]
description: Filament change
gcode: 
    PAUSE Z_MIN=50
    UNLOAD_FILAMENT

to work during colour change while the UNLOAD_FILAMENT macro should work alone as well....

    STATUS_READY
    RESTORE_GCODE_STATE NAME=unload_state

So my question to the Macro Gurus, do you think this could work or do you have better ideas (as sometimes little Wick thinks the world is a lollipop🙈)?

hahaaaa, got it....

if you are crazy enough to try out my weird thoughts you need to have customisable mainsail-configs installed ( to have different park positions for Pause/Cancel/Retractions etc, very useful! )

I modified my unload/load macros to include the colour change.

So if you define a colour change in your slicer, and printing comes to the layer with colour change, toolhead goes to the defined position and unloads the filament, when inserting the new colour, simply push   load filament   button, fila will be loaded and print resumes automatically. standard load/unload works as before..

Wasn't even aware of that. Definitely will have a read of it though. Thanks.

As you put out a challenge....

the 2 G1  needs to be modfied for your printersize (mine is for 350)

and also the 2 unloading parts with the values for your hotend as stated ercf_software.cfg (which I wouldn't have found without your ERCF Thread 😉) for forming a tip when unloading

changed a little bit..... so now no longer neccessary to change Park positions or rectractions on Pause or Cancel in the unload and load sections, these values are now taken from the predefined Variables of the customisable mainsail-configs and some other changes, tested and works fine for me, now I just need to find out how to change to the extrude menu of klipperscreen on pausing when colour change, found no way so far, anyone with an Idea ?

 

I placed it in the Printer.cfg macros section before print_start and print_end

Unload_load_M600.cfg
