Machine stops while working.(cnc3018 pro)

The machine stops while working. It only works if you disconnect and put back the connection.
What is the expected problem?

**** Connected to COM7 @ 115200 baud ****

Not really enough to go on but This thread may help.

It is rather long but has a lot of useful information for those starting out with Arduino based CNC.
