I have printed a PLA blower fan adaptor for my M180 and installed a fan in the right-side position for testing... I've plugged the fan into the auxiliary wire located in the right front of the printer housing and it's a 12v 40mm x 10mm 8+ CFM fan as recommended...
When I go to print, the fan does not spin (I've tried two different ones and neither spin when printing starts) Is there something I'm not doing in the software that's keeping the fan from spinning up?
The fan gets warm when you touch the center where the motor is, but it doesn't spin up and I can hear the main board cooling fan speed up and slow down when I plug and unplug the fan.
I saw in the Wiki a set of command lines, but it doesn't specify it this will work with S3D, and where in the command they are supposed to go
From the Wiki:
M106 T0 S100 ; set pwm to 100, max value 255
M107 T0 ; disable pwm
