!! Toolhead stopped below model range

I am running into a bug where I am getting the following error after some time:

!! Toolhead stopped below model range

I suspect that it is due to the AB motors timing out. However, I set my idle timeout to 999999 in my config and its still timing out after around 30 minutes. Is there any way to work around this?

Nothing in my code throws that error. Where are you getting it from?

Hi, Thank you for the response. I am using a Cartographer Eddy Probe. I am not exactly sure where the error is coming from. However, someone on the cartographer discord told me it is a klipper error.

alchemyEngine commented

That line does not appear anywhere in the Klipper code base either. It seems like it may be an issue in the probe software?

cray12399 commented

Sorry, I was mistaken. They did not say the error was klipper. They just said that the error was not related to an issue with the cartographer probe. I did find the code with the error right here though:

https://github.com/Cartographer3D/cartographer-klipper/blob/master/idm.py

Not sure how much it will help with diagnosing this issue. But line 1310-1311 is where the error originates from.

Edit:

It appears the same line appears in the beacon probe code too. So it appears to not be cartographer-specific as far as I can tell. Which indicates to me that this might be some sort of issue with how eddy probes work with the measure_thermal_behavior script.

https://github.com/beacon3d/beacon_klipper/blob/master/beacon.py

The measurement script simply sends the MEASURE_GCODE that you configure in the script, so if what you're using there is throwing errors then I would start be investigating that gcode.

Someone using a Beacon probe was using this gcode there:
G28 Z METHOD=CONTACT CALIBRATE=0

Hmm, interesting. I will try using that as my measure g-code and report back here with the results.

Alright, so I got the same error again despite changing the measure_gcode. I attached my klippy.log in case that might help in figuring out what is going on here.

I checked out the log and unfortunately I can't give you any new insight. As I said, the measurement script does not hook into Klipper at all, but just sends gcode via the conventional interface and reads positions - so the issue is not on my end.

I'd recommend opening up the issue with the Cartographer team, pointing them at the relevant lines from your log:

The only unusual thing I can see is the discrepancy between your kinematic and toolhead/gcode Z positions:
