Components to my 3axis CncRouter?

[UserJ]

ok Im sorry for if this is a stupid question but I'm learning. There's the motors(3), the power supply for the motors, the driver, the power supply for the driver. Is that it? What's a breakout board?

two types of motor driver configs:

1. Breakout board + 3 driver boards.
A breakout board is a board that connects to the computer by parallel port. it then buffers the signals and sends them to the individual driver boards that attach to the Controller Board (breakout board)

2. Hobby CNC, Mechatronics, and TB6560 chinese boards, and others, are "all-in-one" boards. They contain everything in one single board.

Ohh ok. Thanks for clearing that up. So if I get the HobbyCNC the motors will directly connect to it but will I also need 2 power supplies or only one?

you only need one. the board has onboard voltage regulation, so the one power supply gives 5 volts to the logic part, and the 24v-42v goes to the motors.

The thing with break out boards, is you need 2 power supplies, or anyway to get 5v.

Here's a good tutorial on how this person wired up a breakout board with some driverboards: https://www.youtube.com/watch?v=9tzr-QSPzTM

he has two power supplies, one that outputs 5v for the breakout board, and the other that powers the motors

Note that Hobbycnc will not with 4 wire motors. You will also need to solder all the parts on the board. It's a kit.

if you have 4 wire motors, then get the Mechatronics board since it's pre-made and it can use both 6wire and 4 wire. but since i had 6 wire, i still chose the hobbycnc since it had better performance.

you can not use 4 wire motors with the hobbycnc board, so if you have 4 wires, get the mechatronics.

Yeah I've been watching the series of videos he put up. Thanks for clearing these things up. All thats left is figuring out what kind of steppers I need.

Is there a site to find good deals on power supply's? I was planning on checking out eBay but if there's any other places with good deals...

Well, in the video, he recommended the one from Buildyourcnc.com: Stepper Driver and Electronics for CNC Routers

It's $60 for the 36 volt one. $43 for the 24v

One of my local electronics stores has the 24v for $112.. UGH

I checked on ebay, and this person (http://cgi.ebay.ca/ws/eBayISAPI.dll?...=STRK:MEWNX:IT)has the same 36v one for $35Canadian (includes shipping) from china. I'm in the process or ordering one, (once i get paypal sorted out). Seems like the better deal.

This power supply will work on both the video's set up, AND the HobbyCNC board, since the HCNC board can take between 24v and 42v, and 4 stepper motors at 3amps max each = 12amps, but motors dont always use 100% of the rated amperage, so the 10Amp power supply is good.

Nice. Im gonna keep my eye on that. I just searched google and amazon and sure couldnt find one cheaper. Im still tryna figure out what stepper motors I'd need for my machine and learning about ballscrews. So hopefully I'll be able to wrap my head around both those and figure out what motors I need and order the right power supply
