Add filament to the Object Model

oozeBot

I thought this had been previously discussed but I can't find it. Please correct me if I'm wrong or if there is another way to do this.

We'd like to request "filament" be added to the Object Model. This probably shouldn't be top level, but within extruder to cover multi-tool machines. There are probably other things that would be valuable, but initially we'd just like to be able to identify what filament is loaded to run a unique startup script per tool at the beginning of a job.

filament.loaded = true/false
filament.material = ABS/PLA/etc

Both of those things are available now

Filament type

move.extruders[state.currentTool].filament

Filament loaded

sensors.filamentMonitors[0].status

or

sensors.filamentMonitors[0].filamentPresent

Depends on the filament monitor type as to what you need to query

I have a simple switch

Filament loaded
with filament.png

No filament
no filament.png

@owend thanks! We’ll give this a try. I was expecting type to be enumerated in the Object Model but it does not appear that it is.

You can also use M582 to check the status of the filament sensor and trigger the associated macro.

@owend TBH, I was thinking more of the state used when Loading / Unloading / Changing filament from the UI when clicking the filament name next to the tool number.. I just found the filament type in the Object Model - I'm not sure how I missed that before! But I don't know where DWC is getting the state of the filament from..
