Does anyone have an Arduino encoder RPM program?

That is one of the next things I have to do.

We could make a RPM folder in the files section and put any files there

so everyone could use them.

I might be able to extract how Jon did the RPM output from the Atomic leadscrew program.

Thanks Mike, what a shame they do not describe what they did just play boring music.

They did furnish a link for their motor which I will follow.

Hi Mark, thanks for your replies.

I have CUI inc. AMT 102 encoders that I have played around with but never actually got to work.

We have talked about them here in this forum.

I would probably use an Arduino UNO but I have Raspberry PIs also oh and I have Texas Instruments?

LaunchPad MSP430 which I have never?done anything with.

I am most comfortable with the UNO.

I have an encoder off ebay somewhere.

I am in the process of mounting a Servo/Stepper motor as a direct?drive motor on my lathe spindle.

The motor?is closed loop so it has an encoder.

That is the encoder I am targeting?using.

I believe it is a 1000 PPR (Pulse Per Revolution) encoder but that is a guess.

I was hoping to use a RPM program to confirm the count.

I am not a programmer but I get away with hacking other's programs to get what I need.

So I would probably be using a UNO with an I2C LED display.

Ralph,

The rpm sketch is capturing every change in signal on both the a and b channels. So on the 800 PPR encoder I tested with it will process 4* 800 signal changes per rev. If you are going to 5000 rpm it’s probably best to just use the Z channel which signals once per rev. Can you share more details of your encoder such as the PPR and which channels it provides?

Kind Regards

Mark

Yes Mike there was a link, thank you.

Thanks Mark, seems strange to get a error?at ~200 rpm.

But I will investigate (ha).

I will need upto 5,000 rpm.

Here is a link to code on GitHub, tested against Arduino UNO and MKR Wifi 1010 using an Omrom E6B2-CWZ6C rotary encoder bought off eBay. Runs upto ~200rpm before detecting errors which could either be the encoder or ability of arduino to keep up with interrupts, but since both tested arduinos see errors at roughly the same level I'd guess its the encoder.

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.
