Once the control board hung.

Please make sure the wires are well connected. Turn off the printer, and turn it on again.

I have checked cables many times.
After restart the printer works fine for a some time.
But what can I do while printing? If I restart print I lose printed model.
May be is it the firmware or COM port setupt issue? I set COM port to 250000.
How to check the firmware version I dont know.

How about printing without computer? I mean print offline with SD card.

Garbage characters do not appear a few days.
A new problem have appeared.
The computer often lost connection with the printer.
Often during the beginning of the second printing.
I reconnect USB and print successfully.
