Thanks Michael. Ive started my research by watching this

The search continues for an unregulated toroidal PSU

Thanks Clive, I've watched a lot of Joe's Youtube videos. He has put a lot of work into his machine. If I was to build my own unregulated power supply to match my Nema 34's (4.6nm) that each have 3.4 mh inductance I have worked out that the 'sweet spot' voltage would be around 59 volts. Should I be looking at something like this when I buy the toroidal transformer.
https://www.amazon.co.uk/dp/B00MWQDI...4-e511ab4d5346 ? or this that has a higher current (and price) https://www.amazon.co.uk/dp/B00MWQDO...1ab4d5346&th=1
Then the two 30 volt outputs would be connected in series to give 60 volts. I've looked at a few Youtube tutorials but i've still got lots to learn.

Chris you might want to look here:

As the prices from Amazon are a good bit higher then theirs and they are UK based. So you might want to check them out. Save you a good bit of money as well as have a UK based company to back the quality of build.

If I understand correctly you are building a 1200x600 router. if so I personally think you are going way over the top with nema 34 motors and way over the top with the 1000Kva toroidal my router is 1600x1000 using nema 23 and a 500kva toroidal . running 68 v. I can easily get 10mtr/min rapids.

Thanks Michael for pointing me in this direction I did a bit of a google search but did not find this company. They certainly have a wide range of products that are competitively priced. I'm sure I will be using them. I have just watched this Youtube material to expand my knowledge. https://www.youtube.com/watch?v=CAYKno16weE
The chap seems to explain thing quite clearly.

Hi Clive I'm sure your right about how nema 23's would have been more than sufficient. I think my choices could certainly have been better but at the time they were based on an eagerness to get started combined with limited time to research due to other study and work commitments. Also I intended to build a slightly bigger machine but later decided to scale it down. I am now in position where I am committed and can't change where i am with the project so I want to try and make it work as best as possible with the assets I have. I am pondering how other than overspending are there any detrimental effects that I can expect from using nema 34's on my machines functionality?
