From 85e6cd865c7e6e053971cac456155e5fbd97ccd6 Mon Sep 17 00:00:00 2001 From: Kevin O'Connor Date: Fri, 20 Apr 2018 13:15:03 -0400 Subject: fan: Scale fan speed requests between 0 and max_power If the fan's max power is limited by the config, then scale speed requests between 0 and max_power. This makes more sense for typical g-code fan speeds.
