Help Please

Does anyone know how to wire one of these.I want to build a CNC machine and have no idea of what is involved but I purchased one of these on e bay TB4-axis drive board HY-TB4DV-M
I want to build a 3 axis CNC machine and use the fourth axis for a lathe spindle.

Hi can you post a link to this I can't find it on eBay. Did you get a link to a website or to download a manual?

Geoff:

I think it's this:

HY-TB4DV-M Ebay CNC Controller 4-axis - ShapeOko

and the manual is here:
http://www.shapeoko.com/wiki/images/...ler_4-axis.pdf

It seems to be an OK controller and well documented.

Thanks Per-Erik
Johnnyg, not sure what you want to know but you wil need a pc with a parallel port to connect to that card and some cnc software like Mach3 which uses the parallel port to drive the. 4 axes of your cnc machine. Read the manual several times before connecting any power to your card as mistakes involve a nasty smokey smell and lots of dollars. You can get the manual from the links in Per-Erik's post above. You'll need a 24 or. 36 volt power supply to power the stepper motors as well depending on which motors you buy. Spend lots of time in the learning and planning and design stages as you will reap the rewards when it all comes together. Check out various cnc websites for the best choice in what ball screws and shafts to buy and how to calculate the gears and toothed belts to get the correct resolution for each of the axes. There are a lot of important decisions to make before you buy any more parts. What size table, moving table or moving gantry, what pitch and diameter ballscrew, what power spindle motor. Larger spindle motors require variable speed controllers, and maybe water cooling for the bearings( mine has this!).
I cannot over emphasise that you need to learn as much as possible before committing to buy anything as it's very easy to make expensive mistakes. I'm sure you will find someone on the cnc websites who can perhaps help you through the initial steps there is quite a bit of precision mechanical assembly required to put it all together and get it all perfectly aligned, as I'd you want accuracy you have to build accurately.

This is what I ordered 4 Axis Nema 23 Stepper Motor 287oz-in & Driver CNC Kit Longs Motor Free Shipping | eBay and yes it has mach3 software and I do know that I will have to connect it to a parallel port on a computer all i want to know is some pointers on power supply.There is a voltage adjuster on power supply do I need to adjust it to a specific setting.

[Mike.Powell]

Generally the power supply voltage is substantially greater than the voltage rating on the motor. The Motor controller will chop the supply voltage while monitoring the motor current. The supplied voltage will depend on the motor, the motor controller and the specific settings you use on the controller. The best place to find how to configure your set up is in the motor controller manual.


Based on your statement that you "... want to build a CNC machine and have no idea of what is involved...", I recommend the plans for the Momus CNC, which you can find here: momus CNC | benchtop DIY router plans | home page

For $20 you get a very well thought out set of plans along with a detailed explanation why a rigid structure is important and how to achieve it. Even if you don't build this particular design, I think the manual is a great introduction to the important factors of creating a DIY CNC machine. The plans also provide an overview of other aspects of the whole CNC system, and a good list of suppliers. At 170 pages, there's a lot of good material in these plans. (I'm currently building a Momus CNC.)

I also recommend browsing through the CNC Zone forums: Momus Design CNC plans - CNCzone.com-The Largest Machinist Community on the net!

Great to see you take the plunge and build a CNC.
I just wonder why You seem to fix whatever you need without a CNC….

Momus is a great design, but there are two things I don’t like with the setup.
Not studying too much though:

• Just one off center stepper driving the X-axis.
  Here I would have installed a second X-axis stepper or redesign
  using two trapezoidal or ball bearing screws
• The uses of direct belt driven X and Y axis with just one single small pulley.
  Question is the final resolution – maybe ~0,15mm
  
  The specification does not state any resolution and repetitive number as far as I can see.
  
  Besides that it’s a lot bang for the buck and easy to build at home.
  
  Happy building to all!!

I have some pictures here they are in order I just want to test the motors to see if I can get them to move before I go through the expense of building the table or machine.Picture # 1 is the back of the power supply what wires connect here? Picture # 2 shows a pot voltage + or - do I need to adjust this. It is also shown on picture # 1 on right side.Picture # 3 is of the control board.Pictures 1 Thru 6 from left to right shows connections what wires connect here?Picture 7 shows the computer connections I think I have this figured out but you can explain just in case what connects here.Pictures 8 & 9 are of the nema 23 stepper motor.Picture 10 is of the specs of the motor.I'll post the pictures later of the table I am designing to see if you think it will work or maybe if I need to make any changes to it.The end of this has some more info on kit.

Hello johnnyg

A quick reply on picture of power supply with the small pot .
Look here for Specification and you’ll see that with this pot you can adjust the
output voltage between 20-26,4V. Try to tune the output voltage to 24V
which I believe is already done at factory.

How to wire steppers and power supply is in your pictures and manual.
For instance: -V from power supply need to be wired to terminal marked GND on your
controller and +V goes to the terminal marked 12-36V.

What wire colors from the motors go to the control board and where do they connect to it?The motors have 6 wires what colors do you use and where do they connsct to the control board?I see the 4 wire connections in the diagram but they don't say what colors are used and where they are connected to.
