Problems with LED and Cooling Fan on Smart effector
-
changes fans on port over and over..FAN_0 and FAN_2 are DEAD..only Fan_1 work as intendend and i can control it via the M106
Question: how does the board or the slicer know which fan port is used for Hotend and wich is for the part fan?

If fan0 and fan2 outputs never work, the mosfets controlling them are probably damaged. This happens if you short the outputs, and sometimes if you connect a fan with the red and black wires the wrong way round (depending on the fan).
The firmware doesn't know which fan output you use for the hot end fan. It's up to you either to use an always-on fan output, or to set one of the fan outputs to thermostatic control. Fan 1 is normally used for this purpose. By default fan 0 is used for the print cooling fan, but you can change that using the F parameter in your M563 tool definition command(s) in config.g.

hmm…as i didnt touched the board nor the fans before that problem occurs there must be broken mosefets...really trange..all taht happens after i changed from bang bang mode to PID and made that heater calibrations. before that all works like charm..Hotend heater on FAN_2 and part fan on FAN_0
so i guess i have to contact the seller?(reprapworld)

uses the "always_on" port as hotend fan and mapped the tool with a F1 the Fan_1 to the part fan..
