Problem is toolpath in Radius (setup must be changed in machine settings in mach3 control,default is incorect).

If I output code with I and J, toolpath is disaster,  with R is mutch better but still wrong - Radius looks like inverse R line.

On my turning machine (mach3 control, X-Z axis), i use generic fanuc.cps , code is perfect, only i must change U/W in X/Z.

Best regards

@zeljnik2014 I cannot see a difference in the arc output between the fanuc turning.cps and the mach3 turning.cps. Do you have an example?

[zeljnik2014]

First example is fanuc code which i am use, you can see very fine arc line.

Second pic is mach3 with I/J output, chaotic toolpath, i think that is not need any explanation.

Third pic is mach3 with R output and You can see inverse radius toolpath line.

I am made simple programm, include face , rough profile, finish profile and cut part!

Difference is output G2/G3 code.

[AchimN]

Thanks. By looking at the code you provided you are not using this the latest generic mach3 turning post:

http://cam.autodesk.com/posts/?p=mach3_turning

Could you please download the latest one and test again? I´ve tested the output on several parts and all arcs where correct using this post.

[zeljnik2014]

Hello,

postprocessor is now ok. I am tested all operations and works without any issues.

Only changes which i am made is in line G28 Z0 X0, because in tool change or in the end of programm it is not need move in reference point, i like to use G0 Z100 X100 or G0 Z150 X100 in depend of tool length.

But, this is fantastic job.

Best regards,

[AchimN]

Ok thanks for your feedback.

[silas.armbruster]

Hi 

Could you tr to make an option to disable the G28 like in the generic Mach3 mill post ?

best regards.
