Avoid z_calibration if already set about klipper_z_calibration HOT 7 CLOSED

There is currently no way to do this. I will add this feature...

from klipper_z_calibration.

Thanks Titus.
Any idea why my z_offest keeps reducing height between print starts?
Probe accuracy is not an issue.
Currently I'm restarting the firmware between prints which is successfully eliminating the issue.

I have looked through the cfg's and cannot for the life of me find anywhere that is reduces the z_offest.

Sorry, I was wrong! You can do like this:

{% if printer.z_calibration.last_query != True %}
  CALIBRATE_Z
{% endif %}

I will add this to the documentation..

from klipper_z_calibration.

You calibrate everything, print and rerun calibrate_z and the resulting offset changes without rerunning homing, QGL/Z-Tilt or mesh?

Is the value even wrong? Or is the offset then still correct? The fact is that the value may well change when the printer has become warm.

from klipper_z_calibration.

I have G28... so I'll change it to...
{% if "xyz" not in printer.toolhead.homed_axes %}
G28
{% endif %}

I already have....
{% if printer.quad_gantry_level.applied != True %}
quad_gantry_level
{% endif %}

I will change calibrate_z to this as suggested to...
{% if printer.z_calibration.last_query != True %}
CALIBRATE_Z
{% endif %}
SET_GCODE_OFFSET Z_ADJUST={params.Z_ADJUST|default(z_offset_dflt)|float} MOVE=1

I'll let you know how I get on.

All working now as expected. There is no longer a z height reduction between prints... that I can tell ATM.

from klipper_z_calibration.

Glad to hear that! But, I would recommend calibrating z before every print if the printer is closed and can heat up.
