Hi, Im a little confused, I want to build a homemade cnc , and well I have a question, I was planning on buying the xylotex oard for 149.99 but I found out the one on hobbycnc for 79 bucks, the difference is thatis unipolar and I need to solder it, that is not a problem for me but what Im confused is that what ealse I need.... if I buy this board.

Here is the stepper motors :

8 wire MCG IS-23-019 Dual Shaft NEMA 23 stepper motors with a peak torque of 97 oz-in

what else ?

the reason for building it is because I want to create small rc car parts, on carbon fiber etc. Please anyone can give me a feedback thanks.. another thing is to be economic parts not to expensive thanks.

To get the motors to work, you need the HobbyCNC board, a power supply, and wires.

And a computer with control software.

I have a computer power supply ? will that work ? and I have march 2 , and my pc. Any diagrams so I can use the power supply ? or reference because hobby cnc I think it doesnt provided it, and If I want to put fusage in case over current or over voltage ? sorry for my bad english my lenguage is spanish

[mendez]

if the stepper has 8 wires, and on the driveboard has 6 how I conect it ?

[ger21]

2 pairs of wires get coneected together. You need a wiring diagram for those motors.

Here is the diagram for your motors. It shows how to connect it for unipolar in the bottom left corner. Be aware that running it unipolar the holding torque will only be 0.7 times the bipolar torque. https://www.mcg-net.com/electric_mot.../IS_23_019.pdf

but will work ? the unipolar ? because i read something that unipolar boards cannt run bipolar steppers right ?

Our driver boards work with 5, 6, or 8 wire types that draw .6 thru 3A per coil. Simple.

thanks, I already order it Dave on your site.

Don't use a 12v computer supply. The performance will be so low that it's a waste of time. 35-40v would be much better.

[mendez]

but where can I find that ?

[jeffs555]

http://www.mpja.com/ often has good deals on power supplies, and there are usually a lot of supplies on Ebay.

Best and cheapest is to build your own from a transformer, bridge rectifier, and capacitor. You can usually find 24 volt transformers easily, and they will provide about 30 volts DC. Another transformer option is to rewind a transformer from a broken microwave oven. Search these forums for details.
