Posted · Multi-Material Temperature Issue

I'm configuring Cura for a new 3D printer my company is developing. The printer has a 3 material set up, which loads and unloads the 3 materials into one hotend. Very similar to the Prusa MMU2.0. 

 

My issue is that Cura is adding a M104 command for T2 at the beginning of the print after the start gcode. This is problematic as printing starts with T0, but since the temperature has been changed for T2 and all tools use the same heater, T0 is now printing with the T2 temperature. 

 

Hopefully, that makes sense. I have pasted the beginning of my exported gcode to show the issue, the problematic line is in bold. Let me know if I need to clarify anything
