Okay, I've been in contact with Dave from HobbyCNC. He's been great.

To sum things up, here's what I had to do:

I basically looked over every single solder joint, and retouched almost all of...

I'm contacting HobbyCNC now. LOL Yeah, I suppose that could've been done earlier.

The RN for the Y-axis is orientated correctly, sadly. ;)

Here's an update:

I was getting tired of cutting a million wires for the parallel cable to try to switch the step/dir signals for X and Y.

So, I remembered that I had the A-axis available, and...

The J2 jumper isn't a problem. I messed up it's looks(I have a jumper puller, but I was lazy and used pliers), but it's fine. I took it out, and put it back in, but that was after the problem was...

Thanks. Sadly, I'm an electronics noob. I'll try to gain some knowledge in this area.

There is a .1uf for each axis. I didn't even notice it 'til now, but in my picture I uploaded, the chips are blocking the view.

I just went to Radio Shack to buy another gender changer. I'll just run wires in between the two female connetors with the exposed ends folded over so they stay snug, and switch the wires around(2,3...

I have uploaded a high-res pic of the board I took with my camera.

It's around 220kb, so here's a link:
PICTURE

I don't have any means of doing it at the moment.

Maybe I could buy another gender changer so I have female connectors at the end of the cable, and at the controller board.
Then run wires in...

I was understanding everything you said, but I don't quite get that last part. Sorry.
The voltage at the driver chip has to be at least .3V higher than the parallel port? 4.7V is the minimum for...

There are two resistors at the front and back of each regulator.

LM317 has
249 1/4 W 1% opposite the tab side of regulator
750 1/4 W 1%

LM317HV has
249 1/4 W 1% opposite the tab side of...

There is only one LM317 on the board, so what do you mean by "the LM317 that powers the axis your having trouble with" ?

Pin 6 reads 5vdc on all chips.

Thanks a lot for your time and help.

U5 is LM317
U6 is LM317HV

The driver chips look like this:

(nice ascii drawing? lol)

I'll check it, and get back with the results later.

Thanks.

I'll check that card out. What is different about that one? I thought the one I bought was pretty "bare minimum" as it is.

As far as configuring it, I know how to do it(but thanks for the...

It's the new 4-axis chopper board.

The Y-axis is having the problem, regardless of which motor is hooked up.

Is there any easy way to do this? I guess I could unscrew the board and lift it...

I installed a new parallel port PCI card, and changed the settings accordingly.

Same problem.

The voltage is 5v using this card, so the previous idea that 3.4v could cause problems doesn't even...

I don't know why I even made that comment. I ended up saying to myself, "What? This is no big deal."
I ended up using some solid wire and doing just that. Which was how I made the post where I...

Thanks a lot for your help.

I ordered a new cable and a parallel port card after my last post. Hopefully that does the trick.

I just did some reading, and found that 3.3v is normal for parallel ports now.

I guess I should get a card...

Okay........x_x

I tested it AGAIN, right at the back of the computer, and it's 3.4vdc.

But I wonder why the other axes work fine.

Sorry, I don't know what I'm doing. I soldered together this controller board, built my power supply, but I don't know about this printer cable...

Is there an easy way to test the printer cable...

I just tested it again. Reads 4.2v at the end of the cable.

Okay, I swapped motors. The problem is in the same axis.

I don't really think I need to swap wiring. I have the wires really short right now, for testing, and I can see there are no problems.
...

Do I test the voltage at any time, or when I'm actually using it(like testing the two pins for that axis while I'm jogging it)?

Right now(not doing anything), it's reading 3.4v on all of the...

When I jog it forward or backward, it will spin smooth half the time, and just stutter/vibrate the other half. It's just random.

The other two motors spin perfectly fine.
I have the same...

What would cause a motor to studder or lock up when being ran?
Keep in mind they are not connected to anything (except the wires of course).

I have a 3 axis board from HobbyCNC, with 3 motors...

What's a recommended amp/voltage rating for a limit switch?

Awesome thread. I read the entire thing just now. Nice coverage of the entire process.

CF: How much did that version of OneCNC cost you?
