Help Please

[johnnyg]

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 (http://www.shapeoko.com/wiki/index.php/HY-TB4DV-M_Ebay_CNC_Controller_4-axis)

and the manual is here:
http://www.shapeoko.com/wiki/images/9/9b/HY-TB4DV-M_Ebay_CNC_Controller_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 (http://www.ebay.com/itm/200763845425?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649) 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 (http://www.momuscnc.com/)

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! (http://www.cnczone.com/forums/momus_design_cnc_plans/)

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 (http://www.longs-motor.com/productinfo/detail_12_84_159.html) 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.

[johnnyg]

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.

[Perik]

Johnnyg

If you compare these two images (from your picture and the manual referenced earlier in the thread),
you should be able to figure out how to wire the stepper.

Black to terminal A+
Green to terminal A-
Red to terminal B+
Blue to terminal B-
Yellow and White is not wired at all. (Your Unipolar steppers runs as Bipolar).

I base this on that your colored stepper wires match those in the drawing.
If not, you need to check with the supplier or find the internal stepper wiring
setup yourself which is possible.
I do not know this controller at all other than through the manual and your links.
I suggest you take your time to read up about the theme. Building a CNC from scratch
can be a challenging task. I used more than 6 months on my MDF crap but most of that
time did go into the steep learning curve and I still have many "black holes" :-)

When you start the CNC mechanical planning check these sites among others:
EMS-Mderl CNC-Info und Shop (http://www.ems-moederl.de/) Translate using Google...read all the topics and try to understand "why".
and this nice CNC build using mostly China stuff: Ghqp (http://www.ghqp.com.au/)

And don't forget www.cnczone.com (http://www.cnczone.com) - my second home for many months ;-)

[johnnyg]

Thanks this will help but where did you find this picture?This is what I have been asking for all along.

[Perik]

Johnnyg,

If you look at post number #3 in this thread and the second link:

http://www.shapeoko.com/wiki/images/9/9b/HY-TB4DV-M_Ebay_CNC_Controller_4-axis.pdf

you should find the image I refere to besides a lot of other good information.

[johnnyg]

I also see dip switches on my control board and they are set like this ,1-on,2-off,3-on,4-on,5-on,6-off.These settings are set on all 4 dip switches see attached pictures.What I want to know is are they set correctly for 1/8 step motor and if so how or can I change them to a 1/16 setting or should I but I woild still like to know how its done anyway.

[Perik]

Johnnyg,

Again back to the referred "manual".
Look for this table and switch number 5 and 6.
From your writing your steppers seems to be set for 1/2 step (5=on, 6=off) and you can
easily change to wanted Microstepping according to the table.
The most optimal Microstep settings should be decided further down the road when
you "know" your mechanics.

[johnnyg]

Ok thanks thats what I thought just want to be sure.The other part of the question was can I step it down to 1/16 using these motors don't want to burn anything out here?Also I wanted to make sure what the connections are used for on the top left of the attached picture. I know one is for the LPT printer port in the middle.What's the other 2 for one is supposed to be for a joystick controller or ps2 or xbox but how does it connect to it?Would the end plug be correct just to plug it into the connection?

[Perik]

Johnnyg,

1/16 microstepping is safe to run.
About the connectors - again related to the manual ;-)
PIN15 is for attaching a “Manual Pulse Generator” (MPG).
DB9 is for your Limit switches and Emergency Stop.
To add a joystick / Xbox controller you’ll do that by attach those to your controlling PC
Look here for a few options: ArtSoft USA - Plugins (http://www.machsupport.com/plugins.php)

I see this is a common problem with chinese cnc kits, very little instruction with so many promises. I would ask the guys on CNC zone to help you, as chinese controller problems are always asked their due to the little documentation that such sellers provide.

Just be greatful you didnt by the chinese TB6560 junk which only too many people describe as junk.

I hope you get the answers you are looking for.

[johnnyg]

Trying to find out which pins to use with my mach3 program does this info show up in manual? Are the ones in this picture correct? I'm just trying to get the motors set up or just to move.

[Perik]

johnnyg,

Follow Fig. 5 in the Manual (http://www.shapeoko.com/wiki/images/9/9b/HY-TB4DV-M_Ebay_CNC_Controller_4-axis.pdf).

[johnnyg]

Is this picture figure 5 it don't say that anywhere in my manual but would this be the correct way to set the settings?

[johnnyg]

I can hear and feel the motors wanting to turn by holding the shafts and using these settings but they dont move. Are these settings correct and what Else do I need to move them and how?

[Perik]

johnnyg,

Have you tried to wire according to Fig. 5?
I suggest you concentrate on just one stepper - for instance X-motor
pin 16 and pin 1.
What have you done on the "Motor tuning" page?

About the fourth axis (A).
Use A - not C. Mach3 default show only X,Y,Z and A (fourth axis).

I must say I have no experiece with this controller and I don't have your
manual - just the reference from the link I'm pointing to.

Have you made a deep dive into the Mach Install manual:
http://www.machsupport.com/docs/Mach3Mill_Install_Config.pdf
A lot of good reading ;-)

[johnnyg]

Here's the manual that was emailed to me.

[Perik]

Johnnyg

You'll have to look at at Fig. 6 as well and check mark "Enable1" - enable X-axis (pin 4)
