Problem with repetier host 1.6.2 -solved

Hello, is it possible to print both the supports and the part with the same extruder (the one on the left, number 2) in the version of repetier host 1.6.2? The software systematically refuses and does not take into account what I ask: to know to print my part and the supports with the extruder 2 and therefore makes the slicing with the extruder 1. I use the configuration two heads, everything is Configured correctly, for example: printing the supports with “any of the extruders”, printing the object parameterized with the extruder 2, but it is impossible, it always uses the extruder 1 for the part and shifts me The printing of the supports with the extruder 2. I do not know if I was very explicit. It is annoying because this new version would suit me better. Thank you for your answers.
