I've read a few other threads about this machine and it sounds like the supplied electronics (stepper drivers etc) are poor and would need replacing quite soon.

I have seen that the machine is available in a frame only option:

Would this be a good starter for making my own machine, or are there better options? It comes with ball screws so at least feels like I might be able to make an accurate machine out of it.

Failing that are there better kit options or suggestions on parts suppliers for making my own machine.
