temperature drops after a few minutes

Recommended Posts

Hi

Since the exchange of my temperature sensor I observe a strange temp. drop after a few minutes. When freshly switched on, the temp. regulation works fine, but after a few minutes of printing the temp slowly starts to drop (from 230 to 210 - see attachment).

There are NO GCode commands. This happens when using the controller and preheat to a specified temp aswell. The sensor senses correct - as far as I could measure with another device - so I guess the heater has a problem.

any ideas?

It could be that your fan shroud is allowing the fan to blow directly onto your hot end, rather than downward onto the hot plastic. The fan isn't on at the start (default settings), so the temp probably drops when the fan kicks on. You might consider printing out a replacement fan mount, like the one Daid designed on Thingiverse. It works much better than the origami thing they ship.

    • "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.
