@Smplc,

We need people like you that can invest some time in linux.
It's open source you know. It's growing day by day. Up to the sky....

If you can write a tutorial about G71 on this website, Yo, we would be happy !
Tonight i wrote on the forum how to make a webserver in short.

So this is really a good place to be around for machine user's up to mathimatical professor's you know.

I want glasses too for my avatar tommorrow.... Just look for glasses now .... ehhh.... okey... have a good night.

I'd write source such as G71 for my own use and due to industrial manufacturing experience. I considered if Mach4 Industrial control were more productive and if a small business too. G71 could be enhancement to my profile if to be a developer occupationally. Such if I implemented my own G71 non-monotonic, proven reliable enough, it might get encrypted before if it went into circulation and free.

Otherwise, it wouldn't be expected that other people are operating my equipment now.

I might show other ways and ideas to develop algorithms comparable to a G71 than presenting my own script. And without getting too fundamental. I'm still process of developing my own script, testing and debugging. These presently functions or modules.

I would expect those that use CNC controls to act responsibly and safe practice.

I don't have any projects or builds to post at github yet.

Your G71 is probably okay if proven with geometry.

You want to program your own G71 to write it in your CV and increase your chances of finding a better job? Good initiative, keep us updated on your progress.

What translation tool are you using? It is super hard to understand what you are trying to say.

I meant discrete answer and not escalate. Nevermind.

I am interested in following your progress, but your response reads like I offended you.

As of program language is C programming with Ubuntu 'terminal' and 'gedit'. High-level or abstract mostly, including with such modules, macros or plug-in as G71.

Other terms of expression Machinist and instruction.

No offense but irritate. I could be on a basis of relevance and passive.

I would of expected a solution about transmitting a finsih profile data between interface files and functions but it seems unexplainable yet. It could be something more demonstrative within language of source code and terminology. I have some educational material, experience, could experiment and eventually probably figure out implementing G71 type 2 source code. Idea starting question was to reduce consumption testing code and make implementing more approachable.

I could be testing the G71 intermittently and might have unpredicted gaps. I'm studying low-level programming and possibly embedded systems too part-time. Perhaps studies could extend in other computer engineering divisions too. I might have to go back to studying Lua language due to it Mach4 source code and if any more accessible to implement a macro. Mach4 could use C programming language as a register or plug-in.

Hi Andy,
I am game to put the two together.
I have your G71 typeII python remap running.
I made some slight modifications and added G41/G42 cutter compensation to the python remap using some ugly hacks.
Computed the Z axis offset for each cut using trignometry. It is rudimentary and I would like to implement it inside rs274 so that we can use G41G42 compensation from the C++ code directly.
I also have the benporter/G71 running. I see how he has made the profile using profile and endprofile keywords.
Can you guide /review any changes to be made.

Hi Andy, Partik T,

Any ideas on how to compute the roughing finish pass with thickness specified by I,K.
I checked benporter patch and because of monotonic requirement on the profile for both X and Z axes, the roughing finish pass will not eat up any profile segments.
Any ideas on how to handle same for non monotonic passes.

I don't entirely understand the question but:
Could you add the offsets to the tool geometry before passing the data to the radius compensation code?

I did it all from scratch, including the maths. So I have not investigated which parts of the existing code that can be combined and reused
