Hi all, I have just completed the physoical part of a DIY X2 mill conversion to CNC, using the Heavy Metal kit. It was not as straightforward as I had hoped and certainly shows that it is built down to a price, but after a bit of faffing around it is all working nicely.

Now I am building a new controller box based on the Planet CNC Mk3 board, which calls for 8 to 24v power to the board itself, and I have a 24V 25amp power supply for it. However the stepper motors are NEMA23 2.8NM units, and I am driving them using DM542 driver boards, and I am wondering whether the 24v supply I have is going to be good enough. Should I get a separate 36v power supply to power the steppers? For info the mill will be used for mainly aluminium and other soft parts in the main, with some mild steel work now and then

Cheers

Les
