Cheers yes a lot of frustration, it shows its never worth going for the cheap China option.

I have spoken to the chap on CNC zone but not been able to sort it I'm now lead to believe that the vfd may already Maxed out.

Had more issues yesterday doing very odd stuff!

The bed is aluminum with a spoil board on top. The rails on the y axis are supported round rails, we havnt yet been able to measure them but what is odd is that if the rail were bent you would elect the table to be smooth and follow that curve rather than being smooth fort the first half and then havnt angled cuts for the second, sorry I forgot to take a picture of the fault will do so next time.
