The MachBlue screen set from the ArtSoft web site is now at this address: http://www.machsupport.com/screens/MachBlue_setup.zip

The BlueProbeVer3.zip file is...

Artsoft has changed their website. The link given in post #1 of this thread for downloading the Blue Screenset is no longer valid. As of May 16, 2009, it is located at this url...

Accuracy is dependent on the shape of the tool, how deeply the tool is lowered into the centering pipe and how square the sides of the centering pipe are to the axis of your spindle. For hobby wood...

It looks like Artsoft did some reorganizing of their web site so the link to the Blue Screenset has changed. You can now download it from here...

Take a look at post #66. It shows how to open the script for the Y direction probe. On line 7 of the script you will see Code "F4" which sets the feed rate. If you are running a metric...

Here is a you tube video of a corner finder variation of the center finding tool. This was posted by Joe on the Joe's CNC 4x4 Hybrid forum. Works great! YouTube - Zero Edge Finder

Adam-

Looks nice. Thanks for contributing.

BOB in this case is Break Out Board. CAP is capacitor. Take a look at the first photo at the beginning of this thread and you will see the 0.10uf capacitor that I had to add between ground and pin 15...

Yes.

Hagar-

The video showing the tool centering and then touching off the top of the pipe was an early version of the centering routine. As you have discovered, the one available for download from...

Mr. Chips-

That should do it. Give it a try. (If you zeroed z at the top of your work piece it looks like this file will just cause the cutter to run along the surface of your work piece...)
...

Mr. Chips-

The commands in a g-code file specify x,y and z coordinates for cutting. If you use the XYZ Probe to move the cutter to a position on your work piece corresponding to a point in the...

A free end shaft has 2 degrees of freedom plus rotation. For instance, if you insert one end of an Acme screw in a flanged end bearing and hold the other end of the shaft you will be able to freely...

I agree with Martin. I'm using 1/2 inch Acme threaded rod on my JoeCNC 4 x 4 Hybrid mill that is 60+ inches long. I ran into whipping problems at speeds over 240 ipm. I modified the end supports to...

Here's my entry-

The dirty secret is that the angle iron by itself is probably not a suitable guide, but couple it with the precision aluminum extrusion and it becomes quite good. My angle iron had visible warps, but...

How do you think I knew the answer so quickly? I've had the same problem. I don't know how many times I've changed values in the motor tuning dialog only to have them "disappear". Just another one...

Did you press the return or enter key after you typed in the offset amount?

Here's a little more clarification for how to set the DRO after doing a probe. If you want to set up your DRO so that it reads 0.0 when your tool is centered over the edge you do the following...

Here is a diagram of what happens after you run the X+ or X- probe buttons. For example lets say you put your touch plate on the left edge of the piece you want to line up on. If you start out with...

Johann-

In the script shown above, change the line towards the top:

Code "F4"

F4 specifies a feed rate in your current units. Just edit that line in each of the button scripts to the speed...

I've had a couple of requests for modifying the button scripts of the probe panel and I don't really want to get into the modifying business.. However, here are a couple of hints-

Mach3 has a...

Art-

I think we are on different pages....

1) Did you assign your input pin to the probe function? Go to the "Config" menu, "Ports & Pins" and scroll down until you see the "Probe" signal....

Here is the probe plate I'm using to set up coordinates for my various fixtures. It has a 1/4" steel pin in the center instead of a scribed cross hair. When I fabricate new fixtures, I drill a hole...

Mr. Chips-

When the flange bearings are properly broken in and greased up, they have 2 degrees of freedom (besides rotation). By adding a second bearing at the same end of the screw the degrees of...

More confusion with numbers. My value is inches/degree celsius yours may be inches/degree farenheight. Also there is a wide range depending on carbon content, alloy, etc. Our European friends are...

The thermal coefficient of expansion of steel is 11x10-6 in/degree at 20 degrees C. So if your screw is 60 inches long and the temperature changes 30 degrees C the expansion will be: 11x10-6 * 60...

Monte-

I think it should work. You can do a quick test by seeing if the TOUCH TEST led on the MachBlue screen turns on when you touch your probe wire to the spindle/router.

Mr. Chips-

You don't have to modify my code. The code does it's magic by calling the gcode probing function- G31. No hard coded pin assignments anywhere in my code.

Mach3 takes care of...

Mr. Chips-

You need to find an unused input line for the probe. If you aren't using an estop on your machine, I would think you could use pin 15- just make sure you don't have both the probe and...
