### Basic Information: Printer Model: Ender 3 Pro MCU / Printerboard: Creality 4.2.2 [klippy(25).log](https://klipper.discourse.group/uploads/short-url/ladd5Cm3zlwtnpksoKIMuVsIihK.log) (1.1 MB) I was able to get printer connected but when I try to home all, I get an error message saying “Endstop z still triggered after retract”. Is there another settings somewhere that I need to adjust? When I run ‘query\_endstops’ it shows " x:open y:TRIGGERED z:TRIGGERED " Thanks, Lynn ---

Okay all triggers are showing “open” when I move the axis in the center and run the command ‘query\_endstops’. But when I home all axis, it makes a loud buzzing noise. Like it is trying to go past the endstop. [klippy(26).log](https://klipper.discourse.group/uploads/short-url/wTGHRP2NwL07z7GDeBcGAltjjI0.log) (1.9 MB) ---

I suggest you go through all the steps on that document! Start to finish eg the very next step is verify stepper motors ---

Thanks and going to start going through all the steps. I noticed when checking the endstops earlier they all were showing open, so I decided to go through each one to confirm each would show triggered when activated and noticed the z endstop isn’t working because it was unplugged when the bl touch was added. Do I need to reconnect the z endstop or can the bl touch be used at this point? ---

you do not have bltouch configured in your printer.cfg [Connecting BLTouch](https://www.klipper3d.org/BLTouch.html) [BLTouch Reference](https://www.klipper3d.org/Config_Reference.html?h=bl#bltouch) You can use the search function on [www.klipper3d.org](http://www.klipper3d.org) which is exactly what I did to give you those links. ---

To not damage anything you can trigger the respective endstops by hand and query their state while still triggered. ---
