Grbl 1.1 Download

I have Purchased a 3018Pro from Bangood, it worked ok for a while then it stopped responding
on all the Axes, I could only switch on the Spindle. Thinking this was perhaps a fault on the motherboard I ordered a replacement. While waiting for the replacement board the machine started to respond again after installing all the software onto a New/old desktop PC.
Then two days ago it stopped responding again as before with only the spindle powering up.
The new motherboard arrived today so I installed that. Download morph mod. No response at all, the originall board still gave me spindle control. I have reinstalled the drivers and all the other software etc that is supplied through the links on banggood site (Several times) with no success.
What am I doing wrong? I can't believe all the Stepper motors have gone wrong at the same time. I don't Know what an ardwino ?? is other than it is some sort of mother board. I enclose photo of the old and new boards. I hope someone Can help me please.
Thank you Dev
