Thanks, nice to see a lathe routine. one of these days I will get my lathe build done and put your routine to use.

Some reason can not find the Mach Toolbox again; Seems like a simple search would helped me locate it, But to no avail.
(Update Found it: Machsupport Forum\ Support\ Downloads section)

Had to sharpen my lawnmower blades for a new season, so mounted a Dumore tool post grinder on my Z axis head, made a blade fixture holder, then wrote a small script to solve the task. Now I don't have to deal with the grief and they are always balanced. Uses a 3" diameter grinding wheel and does one sweet job, no burning and less mess. Though it does take longer than by hand I can get back to more fun safer things. Like napping.

I did find these replaceable ends, not indexable. Ill look in the catalog tomorrow

check out DA milling system from http://www.hornusa.com/products/milling/
The PH Horn grooving tools are the best.

I found them to be much better tooling for me.

VB and the development of wizards / Re: THCon() ???

« on: March 19, 2012, 06:23:39 PM »

What is THCon ?
if i step through a simple check program

dim a as double
a=THCoff()
a=a
seems that i get a = 0

a=THCon
a=a
seems that i get a = 26
 
a=THCon()
compiler error

a=THCon(0)
unrecoverable error

FAQs / Re: which way is xy as i stand at my mill?

« on: March 19, 2012, 04:57:57 PM »

I like to think; Draw the CAD part with the 0,0 at the lower left corner and then place the material on the router or mill table with that in mind. I have mach3 .xml files that set my axis's either way.

Depends on the size parts I am cutting, the direction I programmed the repeated cuts (I do contour passes, 3d back and forth stepping over every pass). My cross slide seems to be faster, quieter, stronger and only uses one ball screw so I tend to use that as my X. But sometimes working on a very large piece I swap them and machine the other direction. I just think having the Lower left corner being Zero, Zero and Drawing to suit and then machine to suit keeps it simple (KISS)

As Terry states, make your own standards just learn to fully understand how to make it work for your needs.

As you can see it checks for any DRO or LED not equaling zero
I created the plugin for computing 5 axis tool nose position and then drive all the axis's to the position based on 4th and/or 5th axis head rotation, I just added the get data button to see current data values. It was a test in learning multi-axis matrix programming. Took me months to understand how to get it to work. I've found, I'm not that smart, but I manage to muck way thru it.  ;-)

« on: March 01, 2012, 08:51:51 AM »

I wrote a plugin that gave me all the DRO's, along with a few other things
I just have to find what they all referred too.
