Ok, now it is up to me. Thanks for the mounting ideas. Thanks Richard for the update on the Russian activities. The Chipmaker.ru is an interesting site. Google translate does a reasonable job Ralph On Tue, Aug 18, 2020 at 5:38 AM Richard <edelec@...> wrote:

¿ªÔÆÌåÓýRalph, I honestly do not know at the moment if the RELS is open source. There was certainly no copy-write information on the original code I worked with. I have requested an answer from someone who has been involved with the code for a good while.In the meantime you may wish to look at the information available on the CNC-Zone Forum The thread discusses the project and schematics and software are available to download. The project appears to be in version 7 and includes considerably more options than the modified code that I have worked with. As I am not involved in that group, if you have any questions they need to be directed there. The actual site involved is but you will need to brush up on your Russian! Yes the video you show is the original Russian but at a later issue. With regard to mounting the X drive consider yourself lucky to have those two tapped holes. I would scrape the paint away to show the hopefully machined face then repeat what John has discussed. I attach pics of my X mount in the course of build. Not as elegant? as Johns but it works. I really should pull it apart and machine away some excess and add some chamfers! I connected my X screw in a different way to John. I was concerned that the old X screw would swing around excessively so retained it via a bearing see DSC0158. The stub shaft from that locates with the "Oldham" coupling which connects to the stepper. I obviously drilled and tapped my fixing holes in the carriage after everything was lined up as you can see in the photos. After drilling and tapping and refitting it was doweled as in DSC0156. You need to design and make your mounting then drill some oversize holes for the two bolts bolt it up slack, tap for alignment, tighten bolts and pop in a couple of dowels. DSC0114 hopefully shows how I mounted my Z stepper off the "Banjo". The disk on the spindle is the "one pulse per rev" signal for when I had John Dammeyer's ELS. This has been changed to an 1800 pulse encoder to suit the RELS. Hopefully this helps Richard On 16/08/2020 17:26, Ralph Hulslander

Ralph?
I have no carriage gib screws, but tensioner plates, but if I did and the stepper mounting plate touched them,? then simply mill horseshoe cut outs in the plate to clear.? from your photos I cannot see why you would want a mounting plate that deep anyway to even come close to the set screws and nuts. The plate needs only to come down as far as the casting protrudes out. Suggest you measure and draw out the end of the C Slide , overlay a drawing of the stepper motor mounting holes and footprint. and see where you are from there. What you will need to do is to ensure that the area where the plate will contact the casting needs to be flat and square to the CS feed screw. This will avoid any excess load on the? "oldham" flexible coupling when in rotation. A good sharp file and toolmakers square should do this operation, and time and skill. Ball turning is an excellent use of an Arduino based ELS, Oleg ? is a good innovator, full marks to him. Thanks -- John |

Ralph.
more photos of the? Cross slide screw to the stepper motor and they should be more self explanatory. You will need to measure all your reference points for attachment. Basically you are looking to connect a motor spindle to the end of a feed screw. there's nothing really complicated. You can still use the lathe whilst machining and building up the parts. -- John |

See photo attached.Similar to what you need to know. Assuming you are using a Nema 23 ? 3/8" thick ally plate, drill and tap 4 holes the same footprint as the stepper motor 4 x fixing holes. Bore the plate through the same diameter as the motor nose register diameter. Drill through 2 x holes clearance same dia as the holes used for the taper turning attachment. Put the cross slide feed screw in the chuck and drill ream a hole for a double connector Male into the C/S and? male into a "oldham" flexible coupling. that will connect to the stepper motor spindle. Make 2 x standoffs to the correct length that will connect the stepper and plate and the oldham coupling, to the existing taper turning threaded holes. Hope this helps. -- John |

Is the RELS open source?
Is this ?? Anyone have some ideas on how to mount X drive on my Craftsman 12x36 lathe? I need a better picture showing the gib screws which are below the taper attachment mounting holes.
