It doesn't work for me, how do I configure it?

#

more information is required

#

but the short asnwer is you have to define the settings in AFC.cfg for it, and also have a servo named 'cut'

#

in AFC/AFC.cfg:

set the hub_cut_* values (including hub_cut_active: True
under the welcome gcode, after PREP add SET_SERVO SERVO=cut ANGLE=n where n is your 'normal pass through' angle for filament

somewhere in your printer config, have a servo named cut defined, such as:

[servo cut]
pin: AFC:PB11  # RGB4
maximum_servo_angle: 180        # Set this to 60 for a 60° Servo
minimum_pulse_width: 0.0005     # Adapt these for your servo
maximum_pulse_width: 0.0025     # Adapt these for your servo

#

do not power the servo off 5v on the AFC-Lite board, use something with a dedicated buck converter.

Try thanks

error

#

then you don't have your AFC Lite MCU defined as 'AFC'

I'm using the adapter

pastel tundra Mar 30, 2025, 2:01 PM

#

that's good

#

but you still don't have an mcu named 'AFC' hwich is the default

Where do I see this...I'm not good at this...can you guide me?

steady girder Where do I see this...I'm not good at this...can you guide me?

If this is a default install the mcu is likely named Turtle_1. You have the pin referenced to a mcu called AFC which klipper is telling you does not exist.

#

If you are unsure, check your config files for the mcu name.

#

You can try moving the servo definition into your AFC_Turtle_1.cfg file

#

Thank you, I will review and report.

If you are still having problems please run the following script and post the link here https://github.com/ArmoredTurtle/AFC-Klipper-Add-On?tab=readme-ov-file#troubleshooting

#

oh my bad

#

i copied that from a very old install where the defautl mcu name was AFC 🙂

steady girder Mar 30, 2025, 2:33 PM

#

I changed the name

#

#

I left it in AFC_TURTL_1.cfg is it ok?

#

because it worked for me

pastel tundra Mar 30, 2025, 2:39 PM

#

that's fine

#

Another question...how to adjust the servo so that it fits exactly where the fiber passes

pastel tundra Mar 30, 2025, 2:43 PM

#

trial and error

#

use SET_SERVO SERVO=cut ANGLE=n

#

to find the correct angles for passthrough, prep for cut, cut

steady girder Mar 30, 2025, 2:44 PM

#

ok thank
