Z - offset resets after each prints

Flagship K Series Creality Flagship K1 & K1C

Hello, i am having an issue with my z offset. My offset is saved in my printer.cfg under [prtouch_v2] z_offset. The issue is that each time i start my printer the first print is fine because it uses that z offset but when i launch a second print the z-offset is way off. What i found out is that after each print there is a line in the console saying z offset = 0. Then i see the z offset on the left the negative value of my desired offset (see image) and it will stay like that for all the remaining prints. I cannot for the life of me figure this one out.

Printer : Rooted Creality K1C using Fluidd
Packages installed : KAMP and improved shapers
Slicer : Orca

Did you ever find a solution to this? I am having the same issue. I feel like I am doing something incorrectly but I don’t know what.

Buller ? Anyone … Buller ?

I too am experiencing the same issue… I’m trying to isolate whether if it’s the following:

  • KAMP
  • Fluidd
  • Moonraker
    and worst case, rooting it

It depends on how you start the print. Using the screen will override certain custom macros and settings. It’s very annoying, and different z offset settings in different places also complicate it and can have negative effects. I got it working for a bit but it eventually started resetting again. Gave up and just upgraded to this because the load cells kept giving me bad z offsets to start off with.

Okay, after some playing around, lots of resets and firmware rollbacks, I think I got it.

This all hinges on the fact you trust the bed level check it does automatically before a print via the load cell.

  • Essentially you need to reset to factory (but make sure to take down all changes you want to keep i.e. run current for the extruder and rotation distance).
  • This will keep root but wipes everything. Once done, install helper-script and install moonrake+fluidd and improved shapers. Reboot.
  • Go back to k1c screen and do the input shaper + bed calibration.
    Machine is good to use at this point.

Now this is the important part. Do NOT run ‘tune’ or calibration in fluidd UI or the macros. I believe firmware does something funky to these once you reboot. If you need to recalibrate, via the K1C screen.

I haven’t tested this with KAMP so suggest trying what I did first for a few prints, throw in a reboot or to and see if the z-offset sticks. Add KAMP and see how that goes afterwards.

Also use Orca… Creality Print I believe sends something which may interfere with this too.
