Log of hot end power consumption vs. time after a print has completed

Recommended Posts

Hi all,


I'm wondering if there's a way to output the hot end power consumption data after a print has completed. I'm assuming that as the extrusion rate changes throughout the print, so must the power used by the hot end to melt the plastic. My thinking is that if the hot end is held at a constant temperature, then a higher extrusion rate would correlate to more plastic that needs to be melted and more power consumed by the heating element of the hot end. 


And/or is there a way to output the hot end temperature vs. time and extrusion rate vs. time after the print has completed? Then I could hopefully correlate dips in temperature to increases in extrusion rates.


I'm using an S5 and Cura 3.4.1.

Are you a programmer?  Are you familiar with web protocols?  If you go to the ip address of your S5 (or UM3) and then click on the temperature link it shows the power usage of both cores and the bed.  In a graph.  You can look at the javascript code and write your own code to capture the raw numbers and analyze it any way you want.


I'd love to see this data.  Especially if there is a failure of some sort.  I'm wondering if it's possible to determine that you have a nozzle clog due to the power usage (I know the filament sensor detects this also but maybe for the UM3?)

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
