This looks like the problematic line:
1740025696917,2025.02.20 04:28:16.917,ERROR,SC-FW,X2 home runing fault as endstop not trigger when second bump
I guess the right extruder is failing to detect home. It’s unlikely a firmware update would be the cause of this, unless the update failed.
To confirm that, I might suggest:
- Delete as many files as possible from the printer to free up memory.
- Force another update of the firmware. If it won’t do it from the cloud, you can download the binary file from this thread, put it on a usb stick, then do a local update.
- Try to run all the calibrations starting from the first one, after the update and a power cycle.
If it still fails to detect homing then I recommend sending these logs to Snapmaker support by support@snapmaker.com. Because in that case, it seems like some error in the stall detection, which may be a hardware issue.
Time differences can make email support a little slow, but they’re very helpful, in my experience.
