Have EMC, Have Taig, Having nothing but a blank stare?

[SpeedsCustom]

Hello Everyone, I have a CNC package I bought from Ebay. It's a nice package, Came with Keling Stepper 282 motors, stepper driver boards (Don't know anything about them) Except that it is a : k179 Unipolar Stepper Drive: Don't even know who makes it

Picture:



I'm running EMC for a Taig CNC, I'm just setting this up. After looking through the manual I feel overwhelmed and pushed away because I feel like there is so much to do!

I have one stepper motor installed and I just wanted too see if it moves or not, when using the keyboard, using the <---- -----> Arrow keys, I can get the motor to turn ever so slightly if "I tap the left and then the right, but I have to tap the left key before the right key or it won't move"

I pretty much have no idea on how setting up the Hal Config because I don't know anything about the driver, I feel pretty discouraged right now because I only want to use EMC and not Mach3 because I have an older machine only running Linux on it.

Is there anyway you guys can help me out and I'll provide as much info as I can?

I know nothing about them either, but a Google search for k179 Unipolar Stepper found a bunch of links, including this link to the schematic and specification document. Maybe it will be of help.

Thanks for posting, I know who made the Board. It was the guy I bought from EBay, BrentHub, he knows his stuff but told me that the EMC software was pretty intense on what needed too be put in, he didn't have the information I needed, Like it asks for the Config of the Driver.

I don't know what to do

Jason,

Do you have a breakout board? If so, do you have the pinout for it?

If not, then getting one would be a good idea. I personally am using a MiniIO breakout board from CandCNC. It offers the same pinout as a Xylotech. However, there are lots of good choices.

I will try to help you get going. What I need from you to start is:

Are you going to be hooking the motors up direct to the screws?
How many tpi are the screws? (20tpi I believe)
What is the voltage and amperage of your powersupply?

I am a linux expert if you need help with the operating system just yell and I can probably help. Never have run that software package but know the operating system up one side and down the other.

-This is what I have:



This is for one CNC Breakout Adapter for your db25 cable, to attach step and direction signals to your driver boards. This board has 19 screw lug connections. 18 and 19 being signal ground, all connected to the normal ground pins 18-25, and the 1-17 are the normal cnc assigned pins. The db25 connector is a male plug. The screw lugs are the hip-roof type so you can easily see where you are inserting your wire, and will accept up to 16 ga wire.

-What do you mean pinout? Diagram? Don't think I do.


-I had the wires from the stepper directly hooked up to the driver board/resistors using Lugs.

-On the Taig, I believe it's 20 yes.

- 12.5 amp power supply. (But the system has been configured by the designer with the desired resistors so that it all works.

Hope this is a goos start!

If you could help me I'll love you......

OK, this will do for a start. Your BOB (breakout board) is not opto-isolated so if something goes wrong with your drives you could fry your computer's parallel port at a minimum, or your whole computer.

You will have to choose a wiring plan for your system. I used the Xylotex wiring plan because that is the way the BOB that I use is wired.
This is from the xylotex_pinout.hal file.
linksp Xstep parport.0.pin-02-out
linksp Xdir parport.0.pin-03-out
linksp Ystep parport.0.pin-04-out
linksp Ydir parport.0.pin-05-out
linksp Zstep parport.0.pin-06-out
linksp Zdir parport.0.pin-07-out

If you choose to use it, you will need to run wires from connector 2 on the BOB to the step pin for the X axis. Then wire connector 3 of the BOB to the direction pin for the x axis drive. You will need to run a ground from pin 18 or 19 of the BOB to ground of each drive. Repeat for Y and Z using the information from above.
Ystep goes to 4
Ydir goes to 5
Zstep goes to 6
Zdir goes to 7
When you get this done, I will help you set up the "INPUT SCALE" values for the "stepper_in.ini" file.

Does this help?

Oh yea about that, I'm going to be purchasing a BOB board protector for the purpose of protecting my computer. It plugs between the BOB connector and the computer.

I'm going to read this more carefully when I get the chance, but the Drivers were already pre-wired to the BOB. I mean I don't have it in front of me so I don't know which numbers run to which, but i'll have to check it out.


Make sense?

Yes, good luck,

I won't be able to look at it tonight, but tomorrow I'll post again. I think i'll be alright, just need your help, thats all

[SpeedsCustom]

Oh and just if this helps, the designer told me that Mach3 works fine with this system, so maybe Mach3 has a certain pin config we might be able to work, don't know if this helps.


Edit- Acondit, I just looked at my setup and it was pre-wired just like you described I'll have too look at the Hal Config tomorrow, think were on the right track

Ok, So looking at my controller last night, it was already pre-wired this way, the way you showed me. I just checked my EMC and I had Sherline Inputs and they were different from what the Pins should be. I switched it to the xylotex and it matched what you said and it makes sense now. Otherwise, the Sherline Inputs would NOT match from the Lugs too the Controller.


I'm ready for the next step
