Hello, almost ready to pull the trigger on my cnc only a couple of things I can't figure out or decide. 1) I am going to use the Panucatt Gradus M1 controller with the Bigfoot drivers with 4 nema 23 269oz steppers (Hybrid - Nema 23 Bipolar 1.8deg 1.9Nm (269oz.in) 2.8A 3.2V 57x57x76mm 4 Wires). I am not sure what power supply I need? Do I match the amps on the steppers or the drivers. The website says that Bigfoot takes 3a @ 48v? (I would like to find a power supply that I can order with the steppers from steppers online, since I'm already ordering the steppers there) 2) I need to get a quiet cut spindle because I live an an apartment. I was looking at the quiet cut spindle that smw3d offers. What I am curious about is I see a lot of spindles that look similar but don't say quiet cut, are all spindles quieter than routers and if so what are some affordable options other than smw3d that I may have missed (aside from sites like ebay or amazon, I prefer to buy direct on big purchases. I have bad luck with ebay/ and china purchases)? Also smw3d website recommends the 400w @ 48v power supply, they want 40 at steppers I can buy them a little cheaper but they don't have a 48v 400w only a 48v 500w will that work?
