Hey guys.

I had a cnc3040 about two yars ago and worked flawlessly, Due to funds I sold it, now I have acquired another one but for the life of me I cannot get it to respond, I have tried several Mach3 setup files.

Now Its not the connection or the control box (or at least I am sure) as When I do a driver test the motors 'sing'



I am at my end with it any ideas please?
