CNC SHARK PRO PROBLEM

Hi,

I just purchased a cnc shark. Being new to cnc I am fighting the learning curve and studying the tutorials. I am having a problem with my machine losing info. The first thing I notice is that the forward speed adjustment in the jog program starts out o.k. and works well on fast but later it will on it will only run in slow position even though it is set for high or medium. also it seems to skip some lines of g-code.Example: in carving the velocette tutorial it omitted the V. After it finished running I ran it again and it picked it up and turned out o.k. I was running my router at about 1/2 speed(around 15000 rpm and I had the forward speed set at 50% even though in Vectric software the speed was set at 100 in per min. I am wondering if maybe I have a bad step motor or maybe the processor is bad. I would appreciate any suggestions?

Please help.

I didn't find the right solution from the Internet.

If it ran the correct pattern the second time but not the first, I would suspect a physical problem. If you had a g-code problem, you'd expect to see the same result both times.

How large was the skipped portion that worked the second time? I would expect a skipping motor to not realign itself, but to stay off for the remainder of the cut.
