Implement firmware retraction detection
you looking at using a print start script (akin to how OctoLapse sets its retraction) to suck those out of the slicer, or to acquire the retraction settings in some other manner?
I don't think firmware retraction is usually controlled by the slicer, but if it is then a gcode will be added. Octolapse recognizes the gcode and acts appropriate. The slicer retraction settings would still apply in that case.
Excuse me.. arc welder. Octolapse does too, lol. Since arc welder doesn't need to retract, all that I need to know is that the filament is retracted. Bonus points if I know how much because you never know what kind of stuff a user will pull, like using firmware retract and the detracting manually ( i have seen this) so I don't know where the filament is without knowing the firmware settings.
Yeah, I overlooked the 'FW' aspects of the issue's language...
You're having to deal with a multitude of different firmwares which is a big undertaking.
Out of curiosity (for the marlin builds), I looked at configuration.h and configuration_adv.h. Seems the extruder related settings in the FW is somewhat limited. If there is value in getting them detailed, I can provide same for my printer's FW (Ender 3 v2).
