Every time the
znp_tjc_klipper process starts, it will check if
~/klipper/klippy/chelper/c_helper.so exists. If it doesn't,
znp_tjc_klipper will copy an incompatible version to that location. This incompatible version will cause the newly installed version of
Klipper to fail to start with the error message:
Internal error during connect: function/symbol 'extruder_stepper_free' not found in library '/home/mks/klipper.hybrid/klippy/chelper/c_helper.so': /home/mks/klipper.hybrid/klippy/chelper/c_helper.so: undefined symbol: extruder_stepper_free
Once the underlying issue is corrected, use the "RESTART"
command to reload the config and restart the host software.
