Ultimaker S3 heating up during preparation

[Levo 0]

Hi,

 

I am currently printing a custom material at temperatures much lower than usual (150 degrees Celcius) with an Ultimaker S3. I made a custom material profile for this with the right printing temperature. Due to not being able to change to a custom material on the Ultimaker itself, I just choose (Black Tough) PLA while loading it with my custom material.

However - although the actual printing temperature is correct, meaning it is the same as the settings in Cura (so 150 degrees) - while preparing for the print the Ultimaker shortly heats the nozzle to 235 degrees (which is the printing temperature of Black Tough PLA, the material which the Ultimaker thinks is loaded). I don't want the material to be exposed to such high temperatures.

How can I prevent the Ultimaker from heating up to this temperature while preparing for the print? I looked at this forum and tried some things, like adding the following to the start G-code:

M104 S150
and
M104 {material_print_temperature}

Unfortunately, adding those lines to the G-code did not solve the problem.

 

Any ideas? Thanks in advance.
