Console error Communication timeout during homing probe

In the process of executing homing or QGL, I get an intermittent error “Communication timeout during homing probe”.
Have to reboot and hope for no error next try.

There is a fix which should be implemented by SOVOL in next firmware update.

look for the entry TRSYNC_TIMEOU and change from 0.025 to 0.050
in the file /home/klipper/klippy/mcu.py (SSH to your machine)
Restart Klipper

Thanks!

Hello @sovol3d

Maybe for you?

An innovative solution.

Be sure to remember this if you start getting other communication errors or the dreaded “timing too close”. Your “fix” simply tolerates noise on the USB data buss and doesn’t fix the underlying issue. Other routines are also sensitive to USB noise.

I know, i already equipped all USB cables with ferrite ring cores. Using the enclosure adds a lot of electric noise and the cable shielding is meh. This is the only solution which should be implemented in firmware soon.

I WANT TO DO THIS . i don’t know how to access that file…. i installed putty

but have no idea where to go from there

Try using WinSCP

Graphical file explorer with a built in file editor

Uses the same ID/password as Putty
