Yet another "There is an I2C communication error" on large print

Recommended Posts

Pretty amazing that my $160 printer is trouble free while a Ultimaker 3 Extended, a $4,300 printer, has so many issues.

The latest one is the infamous "There is an I2C communication error" few hours into a print.

I am attaching the logs which I saved to flash drive but I'm not holding my breath anymore to find a solution.

boot-0

boot-1

boot-2

Hi @Oj00, thank you, I have to tell you I have found there could be a problem from the Olimex board I say this because I did switch 2 Olimex boards from 2 printers that are the same (Ultimaker 3 Extended) and the error moved on the other printer, again I did not change the printing head cable. Maybe this information could be useful for some users, even for developers. But then again... how can this be from the Olimex board if the cable is connected to the motherboard? I need to understand more how this olimex board interacts with the motherboard.

    • "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.
