I am in need of help disabling the heating elements and fans for my duet wifi board. Currently, I can get the X, Y, Z motors the signals that they need, but to get the extruding motor to operate I am having problems. I am getting an error that is saying that no tool has been selected. The heating elements are not needed because I am doing "fresh printing" therefore the material is in a syringe and will be extruded. I will be uploading my config code this evening when I get access to my duet board.
