PidTune Ultimaker 2 with e3d v6

Recommended Posts

Hi all, i'm installed an e3d v6 on my UM2.

Now i must to do the PidTune, because the heater cartridge is to 40W. But i've so much problem;

If I connect the printer to my macbook with pronterface, I send the M303 command after a few second pronterface say me:


 >>> M303SENDING:M303PID Autotune startPID Autotune failed! Temperature too high


What can I do?

Tkanks a lot ;)

Are you doing this with warm hot-end?

Marlin gives this message when you overshoot the target temperature by 20°C. Since you don't specify a target temp it is 150°C by default so if you start with a hot-end warmer than 170°C it will abort.

Anyway, you should do PID tuning at the temperature you usually use -- if you typically print at 215°C, use:


M303 S215

    • "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.
