Changed TRSYNC_TIMEOUT value in “/home/pi/klipper/klippy/mcu.py” file from 0.025 to 0.050, i.e. was “TRSYNC_TIMEOUT = 0.025”, and became “TRSYNC_TIMEOUT = 0.050”, and the error “Communication timeout during homing probe” disappeared, and BL-Touch now works as it should.
Only here there is one “BUT”, Mainsail in the update manager shows that the Klipper files are dirty, i.e. do not correspond to the original, and as I understand it, the next time Klipper is updated, the value of TRSYNC_TIMEOUT will again become 0.025.
If there is a way to write a value for TRSYNC_TIMEOUT in the printer.cfg file, if “yes”, then how to do it?
