Ultimaker 3, problem with temperature on Extruder 2 during print

Posted · Ultimaker 3, problem with temperature on Extruder 2 during print

Hallo everyone. I would like to ask you. I printed such a big object on my Ultimaker 3 with both extruders. In extruder 1 is PLA, Extruder 2 is PVA, because I will need de-solve the printed parts. Printed areas with Extruder 2 are really small comparing to areas printed by Extruder 1. I noticed, that PVA is not melted enough. So I checked the temperature on display and there is interesting thing. When printer print with Extruder 1, temperature on Extruder 2 is stable around 200 degrees. Only couple seconds before, when start to print Extruder 2, temperature start to increase to defined 240 degrees. BUT, when printer print last parts with Extruder 2, the temperature start to decrease and final lines are printed at temperature aroud 220-225 degrees and this temperature is insufficient for PVA. Do you know anybody, how can be this solved? How can be set the temperature on higher level, or how can set temperature to 240 degrees without decreasing to 200 dg.C? Thank you very much for all comments.

    Hi @Bublifuk21,

     

    since this is your first post: welcome to the community!

     

    Assuming that you use Cura as slicing software - the temperature settings are explained in the online manual:

    You can set a custom value for any of the five temperatures if you switch to the "Custom"-mode.
