Basic Information:

Printer Model: voron trident
MCU / Printerboard:bigtreetech manta m8p(stm32h723)
Host / SBC ebb cb1(Emmc)
klippy.log

Fill out above information and in all cases attach your klippy.log file (use zip to compress it, if too big). Pasting your printer.cfg is not needed
Be sure to check our “Knowledge Base” Category first. Most relevant items, e.g. error messages, are covered there

Describe your issue:

… MCU ‘mcu’ shutdown: Missed scheduling of next digital out event

This is generally indicative of an intermittent

communication failure between micro-controller and host.

Once the underlying issue is corrected, use the

“FIRMWARE_RESTART” command to reset the firmware, reload the config, and restart the host software.

Printer is shutdown

And I reboot my printer so:

mcu ‘mcu’: Unable to connect

Once the underlying issue is corrected, use the

“FIRMWARE_RESTART” command to reset the firmware, reload the config, and restart the host software.

Error configuring printer

What should I do?
Help me.
Thank you.

It’s important as far we do not know if it is a genuine Klipper version or is modified by a vendor.

For the latter one we are not able to give support because we do not know that the vendor has changed.
