Check Filament before printing

JMT_3D · 27 Nov 2018, 14:34

Hey,
I was wondering if it's possible for the DuetWifi to check the currently loaded Filament before starting a print job, as it has happened, that the wrong filament was loaded. This happens especially when having multiple gcode files for different filaments on the SD-card.
Surely the slicer would need to put the information about what filament to use into the gcode.

Is there any functionality like this in the RepRap firmware already?

Thanks,
Matthias, JMT3D

@jmt_3d In slic3r's print settings in the output options, for example, I have added PLA_ to the output filename to a saved PLA print settings. I also have different ones for each filament type.

Well that's the easy solution...
Seriously did not think about that. Thanks!
But I'm still curious if there is a way to do it in firmware.

That's one for chrishamm to answer, because he write the filament management and implemented the M701-M703 commands.

As with many other things, a check will be easy to implement when we have added support for conditional GCodes and the RRF object model.
