Subject: Re: MK5 PID tuning?
The MK5 has an entirely different thermal landscape from the MK4 -
more metal to heat and higher distance between the heater elements and thermistor mean it takes a lot longer for heat from the resistors to get to the thermistor, which make the PID settings for MK4 much different. I get a thermal swing of more like +2/-15 degrees but it doesn't seem to affect printing much at all. I am looking to move to a MOSFET board instead of a relay board to drive the heater, and that should reduce the thermal swings some. I should also re-tune the PID but I have no experience dealing with the proportional-integral- derivative coefficients. I think the derivative coefficient should be the one that helps to mute the temperature swings but I'm not really sure. On Aug 27, 4:56 pm, Marty McGuire <schmartiss...@gmail.com> wrote:
