I can not understand where is the temperature setting 175 Deg C  For the second print head T1 is coming from ? I have not used it in the setups. I is also strange how  it is repeating ?

Anyway, this puts the printer into a never ending cycle and the print is never starting ( Printer Tenlog TLD 3 pro)

175° is likely the material standby temperature for T1.  You are saying that T1 is not used in the current print?  Did you disable T1?

You can use the "File | Save Project" command to save the model and your settings.  Post the 3mf file here.
