[BUG] Klipper SKR Mini 3 V3.0 supplied default printer.cfg file has error in the BL touch section #773
Once I added the ^, it worked correctly. Without the ^, I got lots of errors like "BLTouch failed to verify sensor state". I also noticed that the pin on the BL touch would not retract back up when it touched the bed (or even my finger).
BigTreeTech supplies an example printer.cfg file for the SKR Mini 3 v3.0 for Klipper here: https://github.com/bigtreetech/BIGTREETECH-SKR-mini-E3/blob/master/firmware/V3.0/Klipper/SKR-mini-E3-V3.0-klipper.cfg
But there is an error in it.
Here is the section copied and pasted from the file: [bltouch] sensor_pin: PC14 control_pin: PA1 x_offset: -40 y_offset: -10 z_offset: 3.0
speed:
The error is in the _sensorpin: line. It's supposed to be:
sensor_pin: ^PC14
The ^ is missing in the original. According to the official Klipper documentation, "Most BL-Touch devices require a pullup on the sensor pin (prefix the pin name with ^)." https://github.com/Klipper3d/klipper/blob/master/docs/BLTouch.md
Once I added the ^, it worked correctly. Without the ^, I got lots of errors like "BLTouch failed to verify sensor state". I also noticed that the pin on the BL touch would not retract back up when it touched the bed (or even my finger).
Please fix the default file.
