BTT SFS 2.0

Still having issues with BTT SFS 2.0 This is what I currently have in my printerconfig file as per the instructions. But every print when it starts it goes to the back and parks.... just stays paused. It's like the sensor is backwards. [filament_switch_sensor switch_sensor] switch_pin: ^PG12 pause_on_runout: False runout_gcode: PAUSE # [pause_resume] is required in printer.cfg M117 Filament switch runout insert_gcode: M117 Filament switch inserted [filament_motion_sensor encoder_sensor] switch_pin: ^PG13 detection_length: 2.88 # accuracy of motion sensor 2.88mm extruder: extruder pause_on_runout: False runout_gcode: PAUSE # [pause_resume] is required in printer.cfg M117 Filament encoder runout insert_gcode: M117 Filament encoder inserted
Solution:
I found this in the vcore mods section and it works great!!! BTT V2 SFS Smart Filament Sensor install on Ratrig : https://wiki.circuitlaunch.com/BTT-V2-SFS-Smart-Filament-Sensor-on-Ratrig-6d153a7734e14531a74e5e2cc28e1c38 I couldn't find much help on Discord or the web on installing the Filament Runout Sensor. Here is my Tutorial on it with a V-core 3.1 500 on the Octopus Pro V1.01 board. Hope this helps someone set this up....

Getting this to work was more than a bit Tricky for me. Hopefully my settings will help. In the Manual (PDF) linked in the references it shows what the best place to plug it in for your MCU. I have the Octopus Pro V1.01

Printer will work if the sensor is disabled in mainsail. But as soon as printer enables the sensor it pauses.

I can’t PROBE_CALIBRATE. Clicking +0.1 results in the printer going down and back up by 0.1.I can click that button until the cows come home but the bed will not get closer to the nozzle. The VERY first blob of skirt won't stickAnd it interferes with the rest of the print. Adhesion for everything else is great. What's the dealprint suddenly looks really bad. where to start? looks like z wobble but almost layershift.As titel says. I havent changed anything. I think but i feel like something is messing up.V-Core 3 - 500 | Bed tilt adjustment is unreliable: the differences in z-height do not convergeDuring the bed tilt adjustment, the range does not converge reliably, sometimes it only takes 1 or 2Ceramic heater not feeding filament throughFilament is able to feed through until it hits the post of the ceramic heater, it was working fine bX Endstop Always TriggeredI'm having an issue where my x endstop is always showing as triggered in Klipper.
