Title: Gcode/post processor help G77
Post by: M250cnc on September 13, 2009, 06:13:35 PM

I need help with the gcode generated with my cam program "OneCNC"

With a turn op Rough/Finish it generates the following code for G77

N240 G77 U2. R2.4
N250 G77 P260 Q360 U0.1 W0.1 F0.1

When this is dry run in Mach i only get the finish operation hence i haven't included that part of the code

If someone could help me figure out how to get this working i would be grateful

Thanks

I don't think Mach supports a G77 and the post processor from OneCnc shouldn't post that code if it a post processor for MACH.

Thanks Rich

There is no official PP from OneCNC for lathe.

But it is an adaptation of a PP i found on the OneCNC forum

Phil,
Don't know what to tell you as i have never fooled with doing or modifying any post processor. I would think that
OneCNC should provide you one which is done for Mach Mill and Lathe.

Just one of those things you learn from experience, in that, the CAM program may not be worth much if you can't process the information properly for the recieving program. Some CAM programs charge you for one.
Try a post processor for a Fanuc lathe as that may do the trick.

I don't use OneCNC and haven't even looked at their info on the program, but, CAM programs sites usualy tell the PP's they have or give you specifics on the programing for changes. If they advertised that it posts to Mach then you have ever right to expect something from them IMHO.
Sorry can't be of more help.

Phil,
Check the manual's or open Mill and have a look at the Gcodes to see what is supported.
I don't think so as i said in reply #1.

If you have installed mach to the default location it will be in C:\Mach3\Macros\Mach3Turn
If you have a custom profile then there is a chance you didn't clone it from a turn profile and if thats the case then you will not have these macros there, just copy them over from the Turn folder.
