### Basic Information:

Printer Model: CR10S PRO V2  
MCU / Printerboard: MANTA M5P + EBB36 CANBus Toolboard

Hi all, trying to setup my CR10S PRO V2 with an EBB36 board and BLTouch Z probe.

I can get the X and Y axes to home successfully however these are attached to the Manta Board not the EBB. I cannot get the Z axis too home. The Z axis lowers a litttle bit but does not deploy the BL Touch and then stops and gives the klipper error ‘Endstop z still triggered after retract’ . I also cannot get the Part Cooling Fan to run when giving commands via the Klipper interface. Thoughts?

Thanks

Looking at your `klippy.log`, I don’t see where you’ve specified the `[bltouch]` parameter as defined here:

[https://www.klipper3d.org/BLTouch.html](https://www.klipper3d.org/BLTouch.html)

Now, you have set some aliases for the BL Touch and you have a `[probe]` parameter, but the `pin` argument in it doesn’t match the pins in the alias statement.
