Hi folks, new here and new to CNC with a first post. Jogged my first steppers this weekend so just passed that major newbie milestone. I have a three wire fan (new) off the on-board header for the XPro v4. When I first turn on the board the fan runs at high RPM (maybe full, maybe not - but fast spin rate). Eventually the fan slows and stops, and the controller temps appear to run high enough that I'd expect the fan should be running. Is there a fan setting someplace in firmware to control fan speed, or should I just skip the three-wire header and wire straight to 12v? Thanks.
