Klipper Neptune3Pro config - filament sensor

[jfurner]

Hey just a small update for the Klipper N3P config. The filament sensor type appears to be a switch instead of a motion sensor. It kinda works as-is but it usually pauses the print right at the beginning for a false trigger filament runout. Then it seems to work after that, which I'm not sure I understand why it doesnt just keep triggering filament runout.

I replaced section [filament_motion_sensor filament_sensor] with this, and no more pauses at the beginning and the filament sensor state on the dashboard updates correctly.

[filament_switch_sensor filament_sensor] pause_on_runout: true switch_pin: PB4

Thanks again for all your work on this! Its working great.

Thanks for the update! The original cfg was built around the Neptune 3 standard file, so I'll be sure to change the one for the pro. Glad to hear it's working otherwise 😀

I have the same issue on my Neptune 3 (not pro!). Will change the config and test it with the filament_switch_sensor instead of filament_motion_sensor.

You need the motion sensor setting on the 3 standard or it'll give you issues

Sorry for the noise then!

If you're having issues on the 3, take the sensor apart and check for buildup inside of it and/or a stuck encoder wheel

I could finally make it work by increasing detection_length (default 7mm, I've upped to 50mm) and using the filament_motion_sensor (the settings you provided). Thanks!
