SHAPER_CALIBRATE goes OUT OF RANGE

[Mike Eitel]

Hi
I'm setting up my newly build 2.4r2.

It is not the first time that I use klipper.
I setup quit successfully a DIY delta before. Also using accelerometer and shaper autocalibration.
Everything works fine, i even printed some parts for my Pi-TFT50.
I'm now in the phase of optimization.

When I try to use any of the shaper commands I fail.
The machine tries to reach a position smaller X0 .... I tried G90 and G91. Same behavior in all variations I tried.

If I remember right my delta did not try to reach a defined position, but stayed on position an d started with vibrations.

Any idea ore similar experience ?

THX in advance
Mike

I made a dump mistake. Grrr
After some reading in the the klippy source code...
I had partially copied the config of my delta.

[adxl345]
cs_pin: rpi:None
spi_speed: 5000000

[resonance_tester]
accel_chip: adxl345
probe_points: 0, 0, 100 # an example
It is obvious that vibration is around that point... means goes into negative values too.

set to probe_points: 175,175, 165

works like a charm.

Sorry , but eventually somebody runs into the same trap and can learn from my stupidity.

I just looked at your config, its the points where it moves to then start. What size is the printer? For a 350mm try this,

# Acceleration sensor
