I bought the machine a few days ago.
I followed all assembly instructions on eleksmaker.com.
Until step 12, move the axes.
Then e lazer burned continuously, without anything to do on the software, it marked "still work in running"
Since the machine stopped and the software marks me
"Serial port faild, please set serial port and refresh"
But nothing works the USB ports work well though.
It seems that the machine is not installed correctly?
