@Surgikill said in Triggering 'Load Filament' prompt with a macro:
@dc42 Yes, I am doing that now. However, I want the prompt to contain options that are dynamically created based on the content of "0:/filaments". I don't want to update the prompt every time I add a filament, or modify the name of a filament. Just like how DWC creates the prompt when pressing the 'Load Filament' button.
At present RRF doesn't have any string handling routines and no way of extracting file information or file lists.
The best you can do is use the object model item
move.extruders[0].filament
which will show the currently loaded filament (or null)
I ran into a similar issue trying to create a filament change macro to use from PanelDue as my printer is in the shed and my computer inside.
I had to manually list all the filament types I use in an array.
This is what I came up with.
It may (or may not) help in your case.
; ChangeFilament.g
; requires RRF 3.5 or later!
; list of filaments must follow rules for array
