Description

Introduces a new 'infill_fan_speed' parameter to allow specific part cooling fan speed settings during infill printing.

Reduce the fan speed for infill will improve layer bonding.
Also i have a theory that may reduce warping in big prints but i need more testing to back that.

Based in #7906
