@T3P3Tony I have a meeting a super long time ago with the trinamics team, it was the time were they were just launching their drivers. They made to me a presentation, where they showed me on a screen how sensitive was their torque detection on a common nema17 motor. I clearly rememnber thatn even a very soft touch to the motor axis using my finger, was being detected by the driver and shown on screen.
This is basically the stall detection capabilities.
I have a long no started idea to try to tune the 5160 drivers on the extruder to be able to detect a change on pressure change while extruding. I managed to do something (not finished) but woulkd it be possible for you to access directly thjrough firmware the driver data and detect these torque changes?
This would be my idea on how to do it with your actual hardware. I think It would be possible, trinamics offers its API of their drivers to work on such features too.
