awander,
1-Save your Gcodes and Mcodes and load the codes in Mach3Turn.
2-In the cycle menu, move down the codes lines and you will see the toolpath.
3- When you reach the part of the codes you do not want take the line numbers (exemple between 300 and 3000).
4- Edit your codes and delete the lines, resave the Gcodes.
5- Retry it in Mach3Turn simulation to see if you remove the lines you do not need

Hi everyone,
I'm retrofitting a lathe with a licensed Mach 3 + Lazyturn. I'm not able to work with 2 tools, the first in front side and the second in the rear side:
- Lazyturn can not generate the negatives X-coordinates (I think)
- Defining the second tool as "rear" in Machturn,  the tool work as frontal
How can I do? Please, somebody help me.
(Sorry for my language, I'm from Italy)

Thanks
Ugo

How can I do?

All the LT testing done was with a front mounted tool. Rear mounted is not addressed in defining the tool so it is the way it is.
I would need to see the affect if the Lathe was configured as a slant bed / rear mounted tool.
I am going to guess that the code will not work and would need to be manually altered. You should not mix front and rear.

Hood may chime in on using front and rear tool posts.

Hi Rich,
I try to explain it better.
I test the machine with only one tool defined and used in the part program. The number tool is 1. All the tool offset are 0. All the work offset are 0.
The distance between the front and the rear tool is 0.
- If I define the tool as front the toolpath is right.
- If I define the tool as rear the toolpath is the same as when defined front. Only the buttons for manual X are inverted.

I forgot!
I think that an easy way could be to develop Laziturn (very simple&good CAM) allowing to define the tool as rear. It need only to update the X quotes as X=X*(-1).
What do you think about?

to develop Laziturn

Lazyturn is no longer being developed...it is the way it is unless Art decides to modify or change it.

Hi:

>>Lazyturn is no longer being developed...it is the way it is unless Art decides to modify or change it.

 :), very true. I may add to it some day, but it was meant only to be a simple code generator done in a unique way. I have so many projects going on that
I may never revisit it, or I may decide to commercialise it someday so it can grow. But at the moment, even with its limitations, its a handy free utility, and its nice to see its
being used.
  I learn more about toolpathing and 3d every day, so perhaps someday it will all come together in a new project..

Perhaps even containing a wizard for bevel gear blanks ?  ;D ;D

Keep up the good work Art - you are the man.

Hi friends,

I'm trying to work with rear tools. I invert the X-quotes (from positive to negative) using the function "formula" X*-1.
All run well, except the first X-positioning G0 or G1: before going to the right quote (becomed negative by formula), the axis go quickly to a positive (undefined) quote, then follow rightly.
I don't know how can I do.

Thanks
Ugo

Please read my reply #22.

Suggest  a look at the manual to understand how the generated code is compensated. Then consider using a G52  maybe ( see section 6.2  to 6.5 in Appendix F).
