Hi I’m trying to use a Creality v4.2.7 board with the latest marlin firmware and I’m having trouble finding info about the frequency of the PWM output of the fan port. It seems to be too slow to be used with the v4.2.7 board and a Voidmicro laser.
If I change the firmware from soft fan control to fast fan control will that help and what frequency does it default to?
Thank you if you read this!
