I want to get a measurement of the current being outputted to my feed stepper motor in real time. I believe I could use this information with the stepper's spec to estimate the torque output of the stepper at any given time (and thus determine the pressure drop across the hot end).
What's the best way to achieve this? From what I've heard there's no convenient software in place that'd make the RAMPs simply display the current signals it outputs.
Are there any spare pins on the RAMPs well suited to the task of measuring current? My Printer is fairly bare-bones (2013 Type A Series 1, no heated bed, no SD Card, 1 print head) so there's a good number of open pins but alas I don't quite understand what's used for what. I know there are 2 other sets of thermistor pins, can they be adapted to measuring current instead of resistance?
I'd be very grateful for any assistance you guys can provide.
Thanks!
