Anybody know where I can get a k40 PSU in the USA that will control the steppers as well I though I found one but turns out it will not run the steppers also if I have to replace the tube as well should I go ahead a order a new k40 and just take it for parts?
Have you checked http://aliexpress.com? i buy all my laser & cnc stuff over there. There must be a seller who can look at a picture of your PSU, and give you hint of one that works with your machine.
