### Basic Information: Printer Model: Ender 3 MCU / Printerboard:3B+/creality 4.2.7 `klippy.log` Hi all, I have a funny (not realy) problem when I want define the z offset: I homing all the axis. I move the nozzle at X117.5 Y117.5 I use PROBE\_CALIBRATE command in the console. The probe move down two time and after the second time the probe go on the first point of mesh. Now the window for move down the nozzle appear, I clic for move down and after a few clic the nozzle down and immediatly go up. I can’t define the z offset… Have you a tips for me? Thanks ---

Sorry, I didn’t know how to do that [klippy.log](https://klipper.discourse.group/uploads/short-url/fvWadJrfiqQCpkAYEtOvJvo9FUE.log) (600.4 KB) ---

It looks like you simply waited too long (had a coffee?) before continuing your calibration and in the meantime Klipper went into its idle timeout. Just follow: [Probe calibration - Klipper documentation](https://www.klipper3d.org/Probe_Calibrate.html#calibrating-probe-z-offset) ---

Thanks for your answer, (no coffee, but special vitamin to set up klipper for the first time) towards the end I used the probe calibration and at the same time I googled a solution. ---

I tried again: [![](https://global.discourse-cdn.com/free1/uploads/klipper/original/2X/a/ade187455e0e5300a0bf7082c5801ddf31b26887.jpeg)](https://zupimages.net/viewer.php?id=23/10/6n9c.jpg) I think I found the solution in the documentation: [https://www.klipper3d.org/Bed\_Level.html](https://www.klipper3d.org/Bed_Level.html) I think I need to change the position\_min on the Z axis in the printer.cfg file. ---

to me it looks like you have to update the end stop position of the z axis stepper: ```auto [stepper_z] position_min: -1 position_max: 230 ``` Take care bot to crash the nozzle in to the bed… ---

I tried with -1 and -7 but it doesn’t work. I use the manual probe: [![](https://global.discourse-cdn.com/free1/uploads/klipper/original/2X/9/932ef9949de775286d0f522c8a8112f5d398c085.jpeg)](https://zupimages.net/viewer.php?id=23/10/nd85.jpg) When I click on -1, the nozzle goes down and when I click on -0.1, the nozzle goes down and immediately goes up. ---

please paste the stepper\_z section of your current printer.cfg Based on your description, I think you still move out of range. Did you try to lower the nozzle till the probe triggers? ---

Yep [![](https://global.discourse-cdn.com/free1/uploads/klipper/original/2X/1/124638d41f864ad97f09d3fdccf1890ab154941a.jpeg)](https://zupimages.net/viewer.php?id=23/10/jn7m.jpg) “Have you tried lowering the nozzle until the probe goes off?” No, I just use probe\_calibrate. ---

I think I have found I use probe\_calibrate After, I moved down the nozzle at 1mm of the bed I accept and save, I get for the first time a z offset value in the printer.cfg After, I re-use probe\_calibrate And when I use the babystep, the nozzle goes down and up, but I see that the value is correct because the test paper is good, maybe the nozzle goes down a bit more and up for the right value. ---
