Enable/Disable Crash Detection with G-Code?

Is it possible to enable/disable crash detection during a print with g-code commands? If not directly, can a variable be toggled with g-code (namely, the tmc2130_sg_stop_on_crash variable in this case)? For the latter, I can see an argument for not allowing g-code to mess with system variables, but I thought I'd ask. Thanks for the info.

Did you end up finding this?  Im looking for the same code.

No, I never did. A cursory examination of the firmware code leads me to believe it's not there, but I would love to be wrong about that.

Here the possible Marlin g-codes for Prusa printers and other: https://marlinfw.org/meta/gcode/

I think deactivate crash detection over standard g-code is not possible on the MK series.

thanks, i checked them out and it does not look like its available over gcode, shame. Trying to do exactly the same as the OP and i have the printer set up to eject and detect that it has ejected with a camera and motion detection but crash detection has to be manually disabled for the print.

Hello,

if you are familiar with the firmware:

There are service G codes for a comparable function. This allows you to set the threshold for triggering the "crash-detect" function, which leads to the desired result.
Threshold values for the axes are currently X = 3, Y = 3, Z = 4, E = 3.
M916 [X | Y | Z | E] for normal printing (e.g. "M916 X3"); this is not used for homing.
Use a higher threshold (e.g. 10) to switch off the "crash-detect" function for the corresponding axis.
The service G codes must be switched on in the firmware (TMC2130_SERVICE_CODES_M910_M918) and the firmware must then be recompiled and flashed. This G code can then be used in either the user start or user end code of the slicer. The changed settings cannot be saved permanently in the printer using the M500 code.

greetings, Holger 🙂
