Arduino leadscrew: improved 1-axis NanoEls

[@MaximKachurovskiy]

You can now order this controller as a kit on kachurovskiy.com 😀

[@thp1202]

great! thanks for making this open source. awesome stuff

[@stevebonnett1509]

Brilliant project - well done. I've just ordered most of the parts. Am struggling with sourcing the KF2EDG 3.5mm connectors at the moment. I have the same lathe - it needed a lot of fettling. I'd actually seen your lathe review about 18 months ago before I bought mine

[@MaximKachurovskiy]

Lathe in every home! :) Thank you

[@user-sergey12570nsi]

Спасибо за очередной проект, предыдущая версия у меня прекрасно работает на Корвете 407, правда с последними изменениями в прошивке. А так -же для движения суппорта использую Nema 32.

[@MaximKachurovskiy]

Вам спасибо :) Буду благодарен если расскажете про свой станок и опыт сборки ELS на github.com/kachurovskiy/nanoels/discussions - и про изменения в прошивке.

Мне нравится! I have been watching this topic on your channel for a while, this is one of my favourite topics. I have been thinking more about my own design, using a dedicated chip for motion + DRO + output to VFD, and one dedicated for the interface (I am thinking ATTiny 3227 on each), and having them talk over SPI. While мои девушка is visiting her mother, it gives me time to do some more work on it, and now, I am blessed with your updates! Молодец & благадарю вас :)

[@MaximKachurovskiy]

Sweet, the more designs the merrier 😊

[@gilleshenri9529]

hello I find your work really great, I also have a WM210 lathe which I intend to tackle the modification by installing your ALS system and then see if there is a possibility to modify the code by installing a nexion touch screen congratulations again for your work

[@cncdavenz]

I have just completed the install of the original on my OPTIMUM mini lathe and I love it. Thanks.

[@tonycstech]

Am still waiting for the remaining parts. Is there a step by step instructions on how to wire everything etc ?

[@MaximKachurovskiy]

Dave, congratulations, please document your experience on github.com/kachurovskiy/nanoels/discussions if you get a chance :) Thank you!

[@luclaflamme4712]

Nice project ! I will implement quite a few of your modifications when I get the Lathe , later this month. Quick question for you : Did you install the OXA 250-000 Tool post yourself ? Or did it came with the lathe ? I am just wondering how easy it is to fit an OXA on these machines ...

[@MaximKachurovskiy]

Thank you. Installing the quick change tool post is easy as long as you order the size that's not too big. As you noticed I no longer use it though - 2 blocks and a hold down work better and fit nice big tooling :)

[@kolbakolba]

As always great job🦾

[@shawnmrfixitlee6478]

Great share & very good features

[@mihaimastacaneanu8505]

Congratulations for your channel! Brilliant devices, clear presentation! I love very much this kind of "half-dumb" controller for half-dumb people. I am a workshop rat and going full CNC is a no-go for me. I usually make my parts on-the-go but I would like certain automation to speed up work. I hope I'll succeed finalizing one Els. As I cannot find 600ppr encoder but only 400; would it be suited for application and what changes in firmware would imply? Good luck!

[@MaximKachurovskiy]

Thanks 🙏 400 encoder no problem. Just change the value in the code.

[@panq1]

It's nice to have a large LCD! However, the volume knob that only changes the brightness of the LCD, which is used infrequently, has too much presence. It may be enough to make a small hole in the case and operate it with a semi-fixed resistor.

[@MaximKachurovskiy]

Good call, I think one can just put a smaller cap on it and then it will be hard to accidentally turn as the potentiometer is quite stiff. It has to adjusted each time the incoming voltage changes though so I wouldn't hide it inside the body. You can also clip it entirely and just make it flush with the panel and use the screwdriver to turn :)

[@panq1]

Will the input voltage (5V) change during use?

[@MaximKachurovskiy]

@@panq1 no, but it changes if you e.g. power it via USB while updating the code on Arduino. Not a big deal :)

[@humanspirit3432]

Cool! : D

[@frodobaggins169]

Thanks for your els. Would it be possible to add a servo motor to power the spindle to program a stopping angle for gear cutting or bolt circle for drilling. Thanks for your great video.

[@MaximKachurovskiy]

Frodo, thank you, good question, it seems like it would require a completely different style of controller to do that - basically a rotary table controller?

[@frodobaggins169]

@@MaximKachurovskiy thanks for your reply. A rotary table controller would be my guess too with a tooth belt to lock the spindle to the locked motor. Maybe this could be a project for you to think about.

[@JesseSchoch]

nice update!

[@garyhardman8369]

I would like to add one of these to my lathe, however, my lathe has an imperial 8TPI leadscrew. Can this be accommodated in the software

[@MaximKachurovskiy]

Gary, sure, not a problem at all.

[@HM-Projects]

I don't think you have enough ELS kits 😆

[@MaximKachurovskiy]

Correct, I don't have yours yet :)

[@HM-Projects]

@@MaximKachurovskiyI'm redesigning the board to make it more compact with added connectors for optical linear scales and limit switches. I won't be putting together any soon though, stm32 is unobtainable for the moment.

[@MagnusNemo-xc5nx]

Is there any backlash in this system? Would a ball screw be beneficial? Compatible with CNC?

[@MaximKachurovskiy]

There's backlash like in any manual machine but as long as it's the same across the axis it's not a big deal, you learn to work with it. CNC lathe is a tool for different tasks, manual lathe is for quick one-off work I believe.

[@MagnusNemo-xc5nx]

@@MaximKachurovskiy Would a lead ball screw increase system performance?

[@MaximKachurovskiy]

@@MagnusNemo-xc5nx sure, but it will take away the key feature that you can disengage the half-nut from the lead screw.

[@X3msnake]

Greetings Master How reliable has been this controller? Have you had issues with the arduino nano limited processing speed and lack of dedicated quadrature encoders resulting in missing steps/pulses while reading the encoder?

[@MaximKachurovskiy]

Hi! I didn't notice any problems like that but I'm not a very demanding user 😄

[@Roberto-cc4el]

Entschuldigung ... wo finde ich die elektronische Platine für die Version NANO ELS H2? für das 2004 4x20 lcd? Vielen Dank.

[@MaximKachurovskiy]

Hi! Meinst du PCB Gerber für Produktion oder LCD Display? Danke

[@Roberto-cc4el]

@@MaximKachurovskiy da mir dein projekt sehr gut gefällt und ich es gerne in meiner bv25 drehmaschine mit 2 nema mit automatischer verarbeitung machen möchte wie ich aus deinem video gesehen habe habe ich bereits eine nema 23 mit dm542t treiber ich habe bereits das sisplay und den 400 schritte encoder und auch Arduino und verschiedene Knöpfe Ich würde gerne alle Komponenten wiederherstellen, die Sie benötigen, wenn Sie so freundlich wären, mir zu helfen, zu verstehen, welche Leiterplatte Sie benötigen und wo Sie sie in Europa kaufen können ... Ich danke Ihnen im Voraus.

[@MaximKachurovskiy]

@@Roberto-cc4el Wenn Sie 2 Achsen der Drehmaschine (Z und X) steuern möchten, funktioniert NanoEls nicht für Sie - es steuert nur Z. Für 2 Achsen können Sie Rocketronics oder github.com/kachurovskiy/megaels/ verwenden Sie können Leiterplatten für 10-20 EUR auf jlcpcb.com bestellen - laden Sie dort einfach eine ZIP-Datei mit Gerber-Dateien hoch. Besten Wünsche!

[@tonycstech]

Is there a limit for the pitch ? I need to be able to cut very large pitch like 10 or 15mm. Also, because of that, an option to cut compression screw where pitch is changing gradually would be nice addition that only high end machines have. Basically is need to have a starting pitch and ending pitch l, as well as the thread distance. Depth can be dialed in by hand. There is a potential problem with compression screws. They not only change pitch but depth also. So I guess if you plan on making this feature available, it will need second axis to change depth gradually as well. This will be impossible for 1 axis setup but it will enable many users to create filament extrusion screw using this function. Thank you.

[@MaximKachurovskiy]

Tony, correct, conical or compression screws are tough because very few people need them and they are quite complicated. I think at that point it's simpler to use a CNC lathe controller and be able to cut anything you can model :)

Sorry, Pat :) If you're in Europe I can mail you the PCB if you like, got 4 extra.

[@JafferM786]

Does it have metric and imperial?

[@tonycstech]

I think it's both.

[@MaximKachurovskiy]

To cut an imperial thread, I simply Google "8 TPI in mm" and then use the corresponding "mm" pitch e.g. "3.17".

[@JafferM786]

@@MaximKachurovskiy Thanks for replay. It would be great if you can add a button to switch between metric and imperial. But great work thinking of making one!👍

@@JafferM786 there's an alternative software version of NanoEls aimed at imperial users at github.com/gstwrt/nanoels-imperial

[@paulfountain3139]

Does anyone make and sell these ready to go?

[@MaximKachurovskiy]

Paul, not yet, I'd love to sell them myself but the amount of regulation and paperwork is Germany in order to do that makes it a bad idea under 10k unit per year which is not the size of the market we have here.
