MINTEMP and MAXTEMP errors

Recommended Posts

hi - recently recieved a pressembled ultimaker and just getting into it (loving it btw).

Worked ok for the first 5 prints or so but since doing the Marlin upgrade (or possibly a new PLA batch) have been getting both MINTEMP and MAXTEMP errors - am thinking it must be a sensor because the temperature ranges from between 10 and 400+ degress in a matter of seconds.

uploaded a video of it failing here:

any ideas?

thanks in advance for help!

Warren -

Welcome! Glad you are loving the printer!

This does indeed sound like a temp sensor problem - most likely a loose connection. Check the connections from the thermocouple to the board on the printhead (thin wires screwed into the terminal block), and also check that the cables are all properly seated into the connectors on the printhead, and onto the electronics board under the printer.

If you are getting wildly swinging temperature readings, it sounds like a problem with the thermocouple or the associated circuitry. The firmware will throw errors if it gets readings that are out of range, and shut down the heaters - which makes sense to prevent damage from the heater running constantly without proper feedback controls.

It's unlikely to be related to the PLA, and even the firmware isn't likely to be the primary cause - although newer firmware may be doing a better job of detecting the problem. (Unless you built your own firmware and have the temperature settings wrong somehow?) Which firmware did you use to update your printer?

      The goal of this contest is to design a set of people figurines that could be used in such a project to make an area, office or mall seem populated. 
      Think of different types of people in different environments, like walking people, people standing still, working people, and both men and women.

    • Taking Advantage of DfAM
      This is a statement that’s often made about AM/3DP. I'll focus on the way DfAM can take advantage of some of the unique capabilities that AM and 3DP have to offer. I personally think that the use of AM/3DP for light-weighting is one of it’s most exciting possibilities and one that could play a key part in the sustainability of design and manufacturing in the future.
