We purchased the "big box dual", unfortunately we are having problems with the extruders. When the fan is switched on, the extruders do not work properly and they don't heat up. Do you have any advice that could help us solve the issue?
You will need to provide a bit more information, such as LCD display, what you are printing, where the file came from, what slicer you are using and was this a ready built machine or kit. With all that, someone will respond.
