Hi, I started printing using repetier hosts and everything was fine, half of a job started to give error messages and after the printer give the message "command waiting" and doesn't move. I try to replace the firmware but nothing change.

Perhaps the reason for the USB cable, you can try to print with an SD card to see if the issue is solved.

thanks William I'll try. Now the new thing is that the machine, after waiting message, loose the heating plate and the second extruder temperature is 100°C without command.

I think there may be the COM port is occupied in the middle of printing, of course, may also because of the USB cable and the interface.
