Printer stuck due to max temp error

Recommended Posts

Hello Everyone,

I finished my bran new Original+ and I hoped to begin with printing. Unfortunately it always stay stuck on the same problem "max temp error". Here is how it appeared from the beginning until now:

1) I began to print the little robot at first for a try: the print was competed except that at the end appeared a "max temp error", apparently during cooldown because the robot was finished.

2) I sought for solutions on the forum. This leads me to make some change on the print head avoiding the two wires of the resistance & thermocouple to be in contact. I checked the firmware version: 15.01.

3) I ran the bed leveling wizard several time: the first time it completed, but after a while (seems to be during cooldown) I had this max temp error. The next time I tried, the max temp error appeared as soon as the temperature exceeded 100 °.

4) Just to observe the result, I tried to prepare the machine for ABS. Curiously no problem occured during warm-up and the temperature stayed stable at 250°, but as soon as I cooled it down, I had the max temp error.

5) I tried a new warm up for PLA and from this moment, my machine stayed stuck on the max temp error at 100°, and it's now impossible to change this, even after disconnecting the power supply several minutes. I can't find a reset button.

Before it stay totally stuck, I observed that during a max temp error, the measures were completely false and jumped from 120 ° to 700 ° within second. Fan was out, no custom parts.

Every good idea is welcome...

    • "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.
