Fill out above information and in all cases attach your klippy.log file (use zip to compress it, if too big). Pasting your printer.cfg is not needed
Be sure to check our “Knowledge Base” Category first. Most relevant items, e.g. error messages, are covered there

Describe your issue:

…I have gone through the steps to change the printer over to Klipper but am stuck on the BLTouch pins locations in the Printer.cfg.
Klipper just keeps giving the Error about the pin locations not being correct, and I have no idea what they are.
It’s a standard 1.1.3 board with the Pin 27 board thing in there.
I have tried multiple different times after googling but have been unable to get it right.

If you are using the BLTouch EXP adapter, the relevant pin is pin 27 (BEEPER), which corresponds to PA4 and is used as control_pin.

Typically, you will use the former Z-endstop pin for the probe’s signal, which is PC4. Therefore, your configuration should look like:

[bltouch]
sensor_pin = ^PC4
control_pin = PA4
...

Side note: If you have a little money to spare, then get a new board with TMC drivers. This will be an upgrade that you’ll really notice.
