Fan settings not working
-
I am wanting to change fan speed according to layer. I have it set up in cura to do this but it doesnt happen when printing. I end up having to change it manually with the slider. Do I have something setup wrong? In the web portal for the printer it also shows three fans which I only have 2. It shows 'Tool Fan' being a fan along with 'Hotend' and 'Blower'

Well I think I know the issue. Cura cannot address fans. Being that my blower is P2 and not the default P0 the gcode command being sent wont work. So I think I need to rename my blower fan to P0 in order to get this to work. Well never mind, Seems pwm is not working on fan_0. A bit upsetting.
Is there any way to remap fan_2 and make it fan_0?

There are two ways. You can use RepRapFirmware 3 which allows you to map any fan number to any suitable output pin. Or you can use the F parameter in the M563 commands that you use to create tools, to specify which fan is the default print cooling fan for each tool.
