How hard is it to change the board? at the moment I think it will only allow us to use nc studio so changing it would probably solve multiple problems I expect! but this sort of thing is not my strong point.

The pic of the motor mount plate is bellow not sure if it was cad or not but you can see how shocking the holes are and no its not the camera angle making it look worse it was that bad!

The vfd is hl3000-25-t I have a manual I was given I will add the link. A chap on cnc zone has been trying to help but no luck yet, I'm not sure its us doing something wrong or the setting at the moment we have tried all sorts.

Don't start changing anything without knowing that it must be changed and that it solves the problems. It may however help if you'd install a trial version of Mach3 and run that as well. Are you using Modbus to set the set the spindle speed? Are you sure that VFD is a real Modbus capable VFD? Most cheap Chinese VFD are NOT real Modbus. The manual pages are just lousy scanned picture, not pdf, so you must read every word, can not search. It also seems incomplete because the communication is not described. So, if you run Modbus I would suggest to go back to basic digital control, in fact, start with manual control from the control panel. Take the next step when that works.
