Voltage and PWM duty cycle plot overlayed on temperature plot



  • I've got 12V LED strips on my printer, the 12V comes from a 24V PSU fed into a DC step down converter to get the 12V

    The problem is simply the LEDs are dimming once in a while, probably because I've driving a 200W bed heater

    It'll be nice to see a plot of the PWM duty cycle and voltage on a plot. Not just for my rather inconsequential problem, but it would help people identify if they've got a poor high resistance connection somewhere in the circuit, or identify bad PSUs that have bad voltage regulation, or plain overloaded

    edit: I corrected circle to circuit, blaming autocorrect
