Hi Folks,

I've seen the word "Jobber" in catalogs and books for years,
but for whatever reason, I've always been to worried about
looking like an idiot for asking what the heck it is or means.
...

Wow, that is so cool!

Well, so much for all of the alien theories and all that stuff. he he

Like BobWarfield was saying, man I sure could have used some of that
"know-how" info last year when...

Here's an idea I had a couple of days ago:

I'm going to make one in a couple of days and see how it works. Should
work great unless...

Hi All,

Well, there have been no responses to this thread, so I will assume
there is not much interest in learning much more about this unit.

I will say this as a final thought..

I am...

Hello Gang,

I just wanted to post about my newest purchase of the Rotozip router
(RZ1) by Bosch. (a.k.a spiral saw) for use on my DIY CNC wood router.

I started off using my Dremel tool, as it...

Hi,

I've got the HobbyCNC Pro kit with 305oz steppers, and I need to reverse the
direction of a couple of my stepper motors. I looked through the instructions,
but I cannot find any detailed...

You're kidding me?... How am I suppose to tell it when it's
touched the table top for cutting or whatever? There has
got to be something somewhere...

Thanks,
Patrick

Hi Gang,

Well, I finally completed my CNC wood router build, and have setup
TurboCNC on the system. I'm using the HobbyCNC Pro package with
the 305oz steppers.

It took me all night and today...

Hi All,

I've got 3 305oz/3.5A stepper motors, and was wondering if anyone
with experience with this type/style of mill would know if these are
large enough to use on this mill?

Any input...

Hello Matt,

Excellent reply, I can totally understand that! ;)

And, I just started reading/learing about Ohm's law, so although I do not
totally understand that yet, it's in there kind of...

Gosh darn it... You see, there I go misunderstanding again.

This is almost the very same misunderstanding I had the other
day and I started thinking that all of this amperage was a bad
thing...

Nice ebook, thanks.

The one thing that he doesn't explain in there is way the
amperage "should never exceed" about 67% of the total
of the stepper motors?

This is where it gets back to having...

OK, I tested my 19.2 volt transformer, and after it goes through
the bridge and cap., it's up to 28.3 volts! That's a 1.4739
increase in voltage.

It's strange that it would actually boost the...

OK, thanks. that's good info to remember.

Hi Gerry,

Does that apply to all bridge rectifiers in curcuits such as these? I mean,
is that a calculation that I can use to figure out how things are going
to work in any given cnc system I...

OK, so, if the transformer is rated at or below 24 volts for the HobbyCNC system,
then the amperage is a null subject?

Please remember that I am new to this stuff, so I am likely to misunderstand...

Hi Folks,

Okay, so I've spent the last couple of days asking tons of questions about
transformers, and reading as much as I can find on the subject that I can
understand at this point.

So...

ok, thanks Al.

Hi Gang,

OK, I remembered that I had this old practice amp in my bedroom
that I don't use any more, and started thinking that maybe I could
use the transformer out if it.

I tested the 2 leads...

OK, thanks Matt.

OK, thanks Matt, I really appreciate it. That does make things clear for me.

Also, I noticed as I was reading around, that some people are converting
computer power supplies for use on these...

Hi Matt,

Okay thanks for the response.

Question:
You said: "Just use the two 12V wires and do not connect the 0V center tap."

Now, this may sound really dumb, but I told you I was blank...

Hello Gang,

I'm getting ready to put together my controller system, and the recommended
transformer is a little expensive. So I did some looking around, and I could only
find one other...

Whatever happened with these conversions you guys were going to do?
Anything ever come of this?
