I wish RRF could associate fans with tools and M106 Sxxx with no arguments would control the speed of the current tool's fan. Is there a way to do that?
Are you adding the fan association to the M563 gcode in your config.g that defines the tool? The default Toolchanger configurations don't do that and if you do then fan commands then follow the tool around correctly. I'm on RRF 3.1.1 so mine is a bit different but my M563 commands look like this: Code: ; Definitions M563 P0 S"T0" D0 H1 F2 ; Define tool 0 with associated heater and fan M563 P1 S"T1" D1 H2 F4 ; Define tool 1 with associated heater and fan M563 P2 S"T2" D2 H3 F6 ; Define tool 2 with associated heater and fan M563 P3 S"T3" D3 H4 F8 ; Define tool 3 with associated heater and fan
