### Basic Information:
Printer Model: Ender 3 s1 pro
MCU / Printerboard: stm32f401
Host / SBC: Raspberry Pi 3B+ running Klipper & Octoprint
klippy.log
_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 am new to klipper and trying to figure things out. Mostly I am ok with it, reading articles and implementing them.
I am stuck with saving z offset.
I have run
I probe with a paper below the printer head and its a good fit. Just tight enough but not too close to the build plate.
After that I start the print and even the side line is quite above the build plate. I had to set manual Z offset to -3.7 to get it to print on the plate.
Now I dont know what I am missing or doing/not doing something for which I am facing this issue.
I am sure others might have faced the same issue and probably someone might point me a solution already posted but sorry I tried, I couldnt find it.

Your provided log contains no indication that you ever performed a z-offset calibration and saved the value.
Please carefully follow [Probe calibration - Klipper documentation](https://www.klipper3d.org/Probe_Calibrate.html)

Thanks for the direction.
I am not sure why its not in the log but I have done that. I am also using octoprint and I did screw tilt calibrate, bed mesh using Bed visualizer plugin, probe x,y & z offset then save\_config.
Is octoprint messing with log being created ?
Ill rerun all that and send the log again, hope that helps.
Thanks

ok
My bad. I was just running bed visualizer and not actual calibrate.
X,Y calibrate are spot on no corrections needed.
Z however, I keep getting error TESTZ unknown command.
update:
After restart of the Host & Firmware TESTZ z=_._ worked.
After pulling my hair for 2 days, ITS DONE.
Finally working as I want.
Test print at 100mm/s working flawlessly.
THANK YOU
