HY-TB4DV-M

[finsel]

Hi,

I have no enough money to buy a good board.. and I guess this is where my problem started. I need someone to help me to find where is the problem.
I create a video on
[nomedia="http://www.youtube.com/watch?v=rewDMzR-Le0"]YouTube- HY-TB4DV-M[/nomedia]

I have no idea what to do on Mach3. The setting below was provided by chinese:

The definition of 1-PIN 25 of Parallel Interface:
PIN2 Spindle motor
PIN4 X Enable
PIN1 X Dir
PIN16 X Step
PIN17 Y Enable
PIN7 Y Dir
PIN14 Y Step
PIN5 Z Enable
PIN6 Z Dir
PIN3 Z Step
PIN5 C Enable
PIN8 C Dir

The definition of DB9 4 channel inputs interface:
P1 X Limit
P2 Y Limit
P3 Z Limit
P4 STOP
P5 Empty
P6 GND
P7 GND
P8 GND
P9 GND

1st. I don't know if I made right to wire DB9 p4 to p7 ( simulate the Estop button). This is correct ?

2nd. I just installed the mach3mill. What I need to configure ? and where, etc.. just let me know one sample based on the settings provided and I think that I can do that...

3rd. the Computer is pentium3 533mhz (is enough?) with lpt port at ECP+EPP.

Can someone help me what to do ? You know.. the chinese support do not answer, of course.
I need to put it to work on the table just for test , so I can start to build the cnc board....

Update:
I changed the dip switches and the noise stop and all led tunred on.
But the lines in MACH3 do not go to the next line... this problem persist.
A new question: Ithink that the chinese guy sent me a 2,5 amp board not a 3amp board that not match with my 3amp motors... this is the root cause for the mach3 not run as expected ?

Thank you!
Frank

If you have the DB9 pin 4 connected to pin 7, you are giving an E-stop, and it will stop. I am assuming you did the configuration of Mach3 to correspond to the pinout of your controller. If not, you need to do that.

Hi,

The problem was the computer.. must be at least 1ghz.
After fix that, I re-set the dip setting, reduced the noise on the motors.
The boar should be 3,5 amp, so is enough to my 3amp motor

About the db9, yes, thank you, Now I'm able to set that stuffs.

For now, I just need to buy the Lead Screw to use in the table: 1mx1,5m. Do you recommend which one ?

Oh, pls, do you know where in the mach3 I set the Lead Screw settings, and the board size ?


thank you!

You should post the resolution on you tube, as well.

anyone have the correct direction hold times and step timing for these boards?

[finsel]

I dind't set the mach 3 yet.. still buying the stuffs to start to build the CNC.. Also this is a mystery for me too.. if you take it, pls share I will appraciate!
tks!

[Ron Thompson]

I am not sure what you mean by "direction hold times and step timing". I have the board set up I received from Ebay seller Hubbard CNC when I bought it.
On Config>Port setup and axis selection, set Kernel speed to 35000hz.
Then on Config>Motor outputs, X enabled, step 16, dir 1, Y enabled, step 14, dir 7, Z enabled, step 3, dir 6, A enabled, step 9, dir 8.
Then on Config>Output signals, Enable1 check enabled, pin 4, Enable2 check enabled, pin 17, Enable3 check enabled, pin 5, Enable4 check enabled, pin 5, Output #1, enabled, pin2. (yes, pin 5 is used twice).

>Oh, pls, do you know where in the mach3 I set the Lead Screw settings<
You will need to choose the screw first. You need to know the distance the nut will move per revolution.
For example, if the screw is a 10TPI single start, the nut will move 1 inch for every 10 revolutions. multiply this times the steps per rev on your motor (probably 200?). 10 X 200 = 2000 steps per inch. If you have micro-stepping, multiply X that. 2000 X 16 = 32000.
In Mach3 open Config>Motor tuning. Choose the axis. Put your number in the "steps per" block and click save axis settings. Repeat for each axis.

I too have this board and have similar issues. I am running this on 2.4 gig pc and have tried MACH3 and EMC2 software. The same 2 lights come on when power is applied. I thought I had my stepper motors wired incorrectly and have tried 2 (6 and 8 wire). The 8 wire is from a working plug so I do not think wires are my issue now.

The directions from seller were the worst I have every tried to use. I have them in a DOC file if anyone want's to read them.

If anyone has a clue how to get this thing to work I would greatly appreciate the help.

Here is a pic of the board and my testing setup.

Thanks,
Rick

Hi Rick,
What model is your motor ? The wires are correctly plugged ?
And how many amps is your motor ?
I think that you can put it to work, just don't give up and do not plug anything wrong
And also, check if your computer have the parallel port rightly configured (Check BIOS at startup).
Tks!
Frank

Thanks for the assistance.

The 6 wire Motors are Vexta C5121-9212 2-Phase 1.8 Deg/Step DC 5.4V 1.5 Amp.
Red, Green, Yellow, White, Blue, Black.

Here is a link I built that shows the board and has a link to the doc.

Hi,

Do you have more information about your motor ? Like code PK.... ? I can't find any reference about C5121-9212 neither in Vexta web site.
Your controller board is the same as I have. we can set the dip setting after understand what each wire from your motor mean.
Please let me know
see you.
