Duex Heater LED lit....unused

[TampaPrinter]

Hello all. Today I added a duex5 to my corexy in preparation of going to triple Z. Moved the BLTouch, moved X,Y and current dual Z to the Duex (keeping stepper wires away from heater line seemed like good practice). Changed config.g & home files and all seems to work well. There is an LED lit on the Duex that doesn’t seem like it should be. The LED above the E6 heater is lit....though E6 is not called for in the config. Its not lit on startup, but lights after home and stays lit. It’s also the only LED lit on the Duex. I cant find an LED explanation on the Duex like on the Duet2wifi dozuki so thought I would ask if this is normal and what that LED is for. Would also be nice to get a more experienced set of eyes on my config....just to be sure I have not missed something. I have two duet machines now, but I'm still pretty green.

@TampaPrinter said in Duex Heater LED lit....unused:

Its not lit on startup, but lights after home and stays lit.

Post your homing files?

[dc42]

@TampaPrinter, the E6 Heater and PWM5 outputs on the DueX share the same control signal. So the E6 Heater led lights up when you first send a control signal to the BLTouch.

@dc42 I thought it might be something like that! Thanks much for the clarification. It's all working very well!
