A good tutorial. Look under Cutting Width tab.

If you have given up I would suggest hooking black to ground, and the other three to positive.
Reason being, red is hot all the time to keep time running, one of the other two is the ignition hot to...

That is a slower machine, so it will be slow, but should run I think. Being a laptop, it may have problems running a real machine with the parallel port, but that is not the case here.(yet) LinuxCNC...

Make sure you use the removable stuff for small screws! (blue? medium strength?)

What were your spindle speed, feed, and depth of cut?

Yes, it is possible with Linuxcnc if using 38.x probing. If you look back one page the script I posted modified the original Etch Z Adjust code to do that. It can write values to a log file that can...

"Multiply microseconds (us) by 1000 to get nanoseconds (ns)"
Step Time = 1.0 x 1000 = 1000ns

If you are not aware, any one using / experimenting with Arduino may find this interesting on indiegogo.

$9 ARDUINO Compatible STARTER KIT

Made their goal, still 12 days left.

I believe you have that backwards.

And the OP and title of this thread was about different (better) options, not cost.

Yes, as I said, I have been lurking, from the beginning, and HAVE read it ALL.
This was just my input, so make it 835.

I just found it, did not draw it :) Just been lurking in this thread. I too feel there is a better solution out there, just haven't found it yet.
But if you look closely, I think there is a lip...

I ran across this and it reminded me of this thread.
I think some one suggested some thing like this a while back.

I tried something similar.
I coated a plain bare board with a thin protective coating*, then drilled it and used a scribe point to "engrave" around the traces instead of milling without removing and...

Do you have homing switches and did you re-home the machine?
Sounds like you reset zero and/or home to your work piece, (possibly a few times?) and have worked your way out of the soft limit...

There is a limit to how fast the parallel port and software can run.
Take an average guesstimate example:
3 axis with 6tpi on each with 100 ipm rapids
If an encoder is 1000 pulse per rev X 6 rev...

Yes, the curve is steep. Especially if you are not use to command line.

What platform are you using?
What version are you trying to use.

I am using it under Fedora, but it has been a while since I built it. Also used it in Ubuntu from LinuxCNC install in the past. I...

OK. Do you still have the original install disk?
Could you try it to see if you get back to where you started?
You said:

Did you upgrade to 10 using the Linux CNC Live disk?
If it is a "vanilla" copy of Ubuntu it will NOT work!
It must have the real time kernel installed to run Linux CNC. (it will only run in...

Another possibility is use a board outline and use back and outline, and drill and out line if you just want to regenerate only drill or only back.
I THINK it takes its origin from the smallest x-y...

Glad it worked for you and that all that code I wrote is helping some one else!
I didn't test metric well since I work in inch.
Like I said, there were a few bugs. Next time I use it I will try to...

I posted a set of scripts I use a while back:

Fixed. I was unaware this feature was added.:cheers:

I think neil pretty well covered it.
Note - when he says do not daisy chain cap to A then B then C
He means you should go Cap to A, Cap to B, Cap to C. Each load with it;s own feed directly to cap....

I believe neil is asking, and I agree, is if you have the power supply ground (black wire, "-" on cap) tied to your earth "ground"?

I notice the Hobby CNC board is a chopper. when the steppers are connected and enabled it will be "chopping" the signal to them to limit the current when not moving. This can generate a lot of noise...

You say the shields are connected to your controller case.
What is it grounded to? Signal ground? Earth ground? Both? Motor ground? All/none of the above?
If not (or if it is not a good, solid...
