custom build with non smart filament sensor for Ender 3 V2 doesn't work
Because I have no smart filament sensors but only non-smart ones, I have build a custom firmware for my Ender 3 V2. (with bl-touch)
Now the extruder doesn't work and the home isn't in the middle. Also the filament sensor doesn't stop the print.
Can you please advise me what to do?

Make sure your extruder temperature is above the cutoff before trying to move it.
The filament sensor needs to be turned on via M412 S1 in your start gcode before it does anything.
As for homing, you'd need to adjust the probe offset via the M851 command.
Ok, homing adjusted, filament sensor turned on.
Extruder still doesn't extrude during printing. (the temp is normal 210 degrees) I can turn the blue knob by hand, the motor isn't activated.
Now about the filament sensor. When I remove the filament from the sensor, the printer freezes. When I put filament back in the sensor the printer comes back online again.
The behavior of the sensor is the same as in your standard firmware when the filament sensor is turned on. Ender 3 - v4.2.2 Board - BLTouch (which has the smart sensor)
@marlin-firmware-service Yes, I knew it also, but forgot it.
Ah yeah, maybe it is indeed wise to add it to the firmware page as standard step. Certainly for the new people.
