@dc42 I had the heat-sink cooling fan always on and the extruder fan wasn't working due to bad wiring (negative had come loose from connector)
I've replaced the wiring and connected the extruder fan to fan 0, working great now.
Thanks for the tip, Ill move the heat sink fan over to fan 1
also feel free to move this thread if possible I seam to have posted it in the wrong section, meant to post in "Firmware installation"
