??? ??? Thanks John . I tried to read the whole thread on Igor's project several times . Some I understood & some I was totally lost on though I'm sure the online translate I was using didn't help one bit . I was impressed with what Igor &? his thread members were able to pull off . Who knows he may be chained to a table wright code for the war machine in Russia these days . I don't think I had seen the word " guitar " used more times then I did in that forum , & I'm a rocker & just plain music freek .

??? ??? thanks for your work .

Hi Ralph and guys.

I intend to reintroduce the digital feed ELS and RELS files, and photos back into the digitalhobbyist forum next week.

As you remember, the original digital work was very well set out by a Russian guy named Igor ? and basically worked around driving electronically a lead screw for a mini Sieg type lathe.

But the RELS system grew from Igors original work? by R Edwards. Power feed X Z, screw cutting, taper cutting etc etc.?

All the files and photos that were originally entered into digitalhobbyist a few years ago by R Edwards, without my knowledge or consent within 2 weeks were pulled. so I asked Edwards? WHY ??

He said he did not want the KGB knocking on his door because Igors work was not "open source". I am sure Russia has a lot more problems on the world stage at this moment?to worry about electronic?lead screws.

I think it?was a very sad?case at the time of Edwards not wanting to be involved in the RELS unless he had complete?control and you do?it "my way or the?highway",?and no debates. This is called Autocratic?management.?

I know in the past John D had a few issues with Edwards to say the least

when he first bought one of John?s proven controllers.

But time moves on.?

I will reintroduce the RELS piece by piece, and put back info and photos into digitalhobbyist, as I have full backups of? schematics, Arduino, sketches etc etc and AtomicELS? and are all welcome to glean any information that?might be helpful.

The Arduino files reference the?encoder may be beneficial.

I am prepared to answer any questions regarding the RELS? as I built 3 complete units, but bearing in mind I do not have a post degree in electrical engineering

and only savvy with RELS on mini lathes, but a lathe is a lathe whatever size you have.

Needless to say Edwards is no longer allowed to post, read, etc etc any digital hobbyist forum news.

Hope the above information helps current and future [email protected]? members.

Thanks for your understanding, a long time overdue email?from me, sorry for that.

Suitable motor 86HSE116，86HSE154，86HSE82
Encoder lines 1000

Not sure what EGND?is but otherwise it looks like other encoder wiring.
