G71

Mach4 Industrial lathe screen could still be going through some development. Its Hobby lathe screen would be more effective. About the latest Hobby builds its lathe tool nose compensation appeared okay with digital readout.

I could vouch the Mach4 Industrial three-axis use is more than adequate. I haven't used the control productively due it hobby, prototyping and modeling. Additional is studying advance programming and engineering. Lately, I'm not sure how thorough the mill screen is with tool compensation general applications. I do recall that geometry as simple as a square island with corner radius and tool nose compensation accurate.

I did a thread mill program that included Macro B with Mach4 Industrial control. It sure is nice to use Macro B with rough cycles to reduce coordinates.

I went with Mach4 due to is compatibility with hardware and a plus its latest builds include Macro B. Someday G12.1 and G13.1 (G12 & G13 or G112 & G113) might be implemented and looking forward to it.

Much of LinuxCNC is using a parallel port with its hardware and modern computers limited availability. I'm using a Mesa 7i92M with ethernet sort of a motion controller to my laptop computer. Chosen due to an existing CNC control box, hardware and configuration. The 7i92M was basic with its pins and ports about a couple years ago. It might be going through some internal development. Maybe the model firmware would get future updates.

The G71 Python remap is in the interpreter, it doesn't touch real-time. And it works.

Any program language can just rename their executable file G71, G85 etc. Make sure that file name is the same G code programmed.

Okuma's G85 and G87 likely have a bit of a different algorithm of source code because G85 is used with rough turning and facing. G87 finish pass. Rough turning and facing distinguished with different G code's starting. Rough turning start G81 and rough face G82. Both ending with G80.

Okuma has another CNC program build that's similar to Fanuc G code but might not be seen as oftern as Okuma's trademark G code.

@Sm,

The problem with mach4 is that people are getting lazy. It works directly and within 30 minutes.
But after that you will see a periode of window 7 up to 10 failure's. Also mach4 is nothing related to linuxcnc possibilities.
I have a free software from Russia that is developped after Mach4. I get it for free for a lifetime. But i don't use it, It's claimed to be better than mach4. See purelogic.

I only use Linux 64 bit with Ethercat. The best of the best you can get, just like Tina Turner.
Maybe over 4 years i go to 128 bit linux.. but not sure about this yet.



@SMPLC,

Follow linux. Spent your time in linux, become just as good as Andy.
You can make the G71 man page if you want to. Why not?
Andy will give you the link's to start with.

There already is a G71 manpage.

github.com/LinuxCNC/linuxcnc/blob/andypu...src/gcode/g-code.txt

(search that page for G71)

Not too shabby. It looks like the surface feet was kepted up and a good surface finish.
