GitHUb for me is complicated (as in I have never looked at how to use it). I like having a source with download. Ralph wrote:

John, I wonder why neither you nor Oleg, both creators of widely used and open-source ELS systems, don't use GitHub (or similar) service to publish source code. I feel that publishing code on

Mine also has the equivalent of a feed hold. Press the stop button and it finishes what it was doing. So if it's threading it stops at the end of the thread pass. If it's retracting it stops at the

My system is based on Oleg's with a number of changes. I certainly would not have a system without that excellent base code. The original software did not offer flank cutting or additional

The half nut must stay closed through an automatic sequence. I felt a constant cut area seemed more sensible and machine friendly. If further passes are needed to achieve the required size or fit the

Richard is that Oleg's method or did you eliminate his code and add yours? Ralph wrote:

Ah. So you do exactly the same thing mine does for following the flank. The only difference is mine doesn't do the extra move in the Z threading direction before it waits for the index and does the

Hello, All, Like John Lindo, I have also used Richard's system to cut both plunge and 29.5° "compound simulation" threads, and can confirm that both work well. Unlike John, I have only had my

My X infeed per pass is based on a constant area calculation where obviously the depth of the very first pass dictates the area of the first cut and therefore subsequent cuts. When commencing an Auto

Well if you are following the hypotenuse of the 28.5 degree triangle then for each pass X is a bit deeper and Z is closer to the headstock if the thread is cut towards the headstock. Simple trig.

Wow John you have got me worried now! I did not think that it was "clever math" so I had better go back and check what I did. Richard

Sorry, I meant Richard. John Sent: October-18-20 9:31 AM To: [email protected] Subject: Re: [digitalhobbyist] No compound Hi Ralph, So you have written the 'clever math' to do this.

That was not me, believe me I am not even capable of thinking of what I might want to do. That was Richard! Ralph wrote:

Hi Ralph, So you have written the 'clever math' to do this. Super. Looking forward to a detailed explanation on how you've done that. John Sent: October-18-20 1:38 AM To:

John, John, Jack or Jill I am so glad to get the responses. I am one step closer to actually using some form of motorized Z with the Z motor mount. Hopefully X will follow. Ralph

Wow John, that looks great! One of these days I am going to have EazyCNC <http://www.eazycnc.com/welcome/welcome.php> running on my mill. Ralph

Actually John I think that Ralph was directing the question to John Lindo! Further to the comment you made that I repeat below, sorry John you are incorrect. I am using the Russian ELS on on Arduino

Hi Ralph, Much of the explanations are probably in the E-Leadscrew archives which unfortunately are pretty large. My ELS uses time to determine where the start of the thread is. If the spindle
