Turn off fan blip on boot (duex5)

jontek2

Hey,

I have a LED-strip connected to one of the FAN-pins on my Duex5 and on boot it blinks the LED's due to fan blip.

I've tried using the B0 command;

M106 P3 B0 S1 H-1

But it doesn't seem to work. I'm using v 3.1 of the firmware.

Is there a fix for this?

@jontek2 the boot up blip is before the pin configuration is applied to make sure that any fans run directly after power up in case you power cycled your printer in an emergency. This is done so that the hotend fan kicks in immediately (i.e. before thermistors are set up) to avoid heat creep.

If you have a spare heater output, you can use that to power your LED strip of the voltage matches, which will not get blipped at power up.

Thanks for the reply!

Ah okay. It's no biggie, just a little bit annoying

Thanks!
