I do plan on doing the checks in stages but I thought about seeing if I can prepare a check list and go through it step by step.

I have ordered another db25 cable so going to check the cable.
I am going to grab lithium WD40 spray and give the ball screws and rails a coat.
I am going to test the motors on their own.
If still no luck I will check the board settings as Doddy suggests.
If still no luck then I will purchase PSU I found this one https://www.ebay.co.uk/i/15261107092...9916224&crdt=0, are these safe to purchase or do i need to go to some specific website to avoid dodgy components?
then go from there by purchacing a bob and stepper drivers as recommended by M_C.
Thanks guys btw for the help thus far and don't panic I am not going to do all and everything in one go.
