As seen in

from teaching tech, he uses pin 27 for the bl-touch and pin 29 for the filament runout sensor.

its at 8 minutes when he talks about how to use the pins on a ender 3.

Would be great if you added that!

Honestly, if you're looking at going through that much hassle, it would be easier and more reliable to upgrade the mainboard to a v4.2.7 replacement.

These have simple, plugin ports for the BLTouch and the smart filament runout sensors and are supported out of the box.

I thought it would be easy for you to program and an extra feature.

It is easy for me to solder, if I have the printer opened up for the bl-touch, it is another 5 minutes for the runout sensor.

But it's your call, I respect your decision.

 

Thank you for the easy firmware service! I really like it.

I have a V4.2.7 Board and plug in the Filament sensor in the right spot. Do i have to change some settings in the code of Configuration.h ? I uncommend the line 1175 witch said define Filament_Runout_sensor. Is this enough ? or do i have to add a line with the pin?
