How responsive is the temperature control?

  • I am actually looking at putting a duet on 3 different projects. That's a big reason for some odd questions.

    How responsive is the temperature control? How often does it turn the heater on & off? What are the PWM rate and PID update frequency?

    Is it fast enough to control a hot air solder rework station within about 1 degree C?

    The PWM frequency is configurable with a GCode but it defaults to 250Hz for an extruder heater and 10Hz for a bed or chamber heater. By default the PID loop measures the temperature and makes a correction every 0.5 seconds, but that too is configurable.

  • Thanks! Is it calibratable, with a scale and offset?
