Nice work Doddy and thanks for your efforts.
I will get the required power supply, what current rating will cover my needs?
Should I also have a 24 v supply to cover other potential requirements?

I dont think that I flashed it or spiked the card but i suspect I would have a tough job convincing CNC4you that it was a simple warranty failure
But I now know I can get something adequate from the far east for less than £6 inc carriage and vat which realistically is far less than their P & P on a replacement part.
While initially they were good for support , they now seem to get a bit uppity if you ask further questions so you feel reluctant to approach them.

Who needs them anyway when the support here is so good.
