John:

  , yes, I should have thought of it long ago, but I wrote the code generator to put out
only Mach3 code figuring Id add a post processor later to put out any code type. Of all the sections
of GT the code generator is the one I will replace first, I wrote it as too combined a class, Ill rectify that
when GM gets deleted, hopefully by summer..

Art.
The old AHHA software uses w for the rotary as well.

thanks!!!

  Glad to hear its workable. Ill implement a change so you can specify a W as the 4th axis. Im in the middle of some
code work so it will after next release, but its on my list.

Thx

this machine is a 3 axis cnc with a 4th axis rotary table which in their software the letter is w.  the code will work once the a is changed to w. i have to take out some of the notes at the top, open it up in my software and renumber your code with my software, save it then i can use it.  both party software here are almost on the same page. i will attatch a sample text file from my other cad programs that work directly with the cnc software.  once this file is output from the cad this is how it should look. thanks for all your help and everyone else's help as well!!  we all like to learn new tricks of the trade.

  On rereading your note.. IS this a machine which is really a 3 axis unit, but the Y is used to drive the A when its needed?
GT will put out code that does need all 4 axis, the X,Y,Z and A all run when your cutting a gear with a straight flute..
if you were using a involute shaped cutter you could cut without the Y motion....

Hi Kevin:

  Hmm. OK, first.. are you getting both left and right handed at this point? The checkbox is reversed, but you should be able to get one of each , but make sure you press regen after changing the selection.

Ok, second issue. , to ensure
I understand, your saying your control cannot put out 4 axis of motion at once? The 4th axis code for Gearotic
does indeed move all 4 axis, but typically only 2 or 3 at a time.. look at the following helical code for example..

G1 F600.0X -4.0000  Y 0.0000 Z -3.0000 A 31.2025  //this moves 3 axis.
          X -4.0000  Y 1.5000 Z -3.0000 A 31.2025        //this one only 2 axis.
          X 4.0000  Y 1.5000 Z -3.0000 A 16.7975            //same here...etc..
          X 4.0000  Y -1.5000 Z -3.0000 A 16.7975        //only 1 axis here..

  What is it your CNC doesnt like about this code? Its pretty basic flavour 4 axis, (other than possibly W as the A axis..).
Is it that it cant handle two lines in a row with the same coordinates?? I can add a checkbox for a W axis , and I can likely
make it not put out redundant motions.. do you know exactly what it doesnt like? What kind of machine is it , perhaps I can see
from its specs what it isnt liking..

art, '
i had the cnc guys i bought my machine from because i could not get your code to work with their controller.  they told me that if this program is a spiral type motion the y axis should not even be in the program because it just uses the x axis and the rotary axis correct? or no? he says his control cannot process 4 axis at one time when one is not needed.  he told me to contact you to get the post processors that will work for his control or add an option in the program to select the processor that you need to go with each individual machine control.  this is all kinda new to me so if you can shed a little light on this subject i would appreciate it! 

thanks !!!

Kevin:

  I will also add a selection for axis letters..

THANKS!  i'll try that
