Finally Installing the Servo on my Lathe | Electronic Leadscrew Part 27

[@Clough42]

If you're looking for a TI LaunchXL-F280049C board to build the ELS, both Mouser and Digi-Key are expecting a few hundred in July with more shipments later in the year. The chips on these boards are used in automotive applications, so the global semiconductor shortage has been really frustrating.

[@lukeamato2348]

Having worked in composites for quite along time just make sure the fiber orientation is balanced and alternating through the layers like your 0-90 degree layers and 45 degree ones to keep strength similar in all directions ...unless you want something to flex more in one direction than another

[@routercnc9517]

Thank you James. I’m keen to get started so I will keep an eye out for them.

[@SRED]

James, I have had the TI LaunchXL -F280049C on backorder with Digi-Key since January 2020. Periodically I search the web for them, and I was shocked last week when Texas instruments showed them IN STOCK! I quickly ordered the board and it shipped from Singapore within two days. To my shock it showed up Friday 5/13/22. So, if others are waiting on the board, they should check with Texas Instruments. I programed the board per your Part 10 video, and everything appears to work as I expected except my feed rates and threading, everything is way to fine. Maybe 3 times too fine. I'm sure my issue is a simple setting in the code. I had a few questions about my setup and was wondering if there is a communication channel you prefer to receive questions.
I can't thank you enough for your videos on the G0602 VFD and ELO conversion. It makes my machine enjoyable and much easier to use. Your videos are the best I have seen on how to do projects. Thank you!
Oh yea, I tucked my servo in the same place you did a few months back while waiting on the TI board. It's very clean setup now.

Can't thank you enough for the ELS project. Along with a VFD, definitely the single biggest improvement I've made to my lathe. As a hobbyist with no machining experience, it's really helped me learn how feed adjustments can help with chip control. And as an EE, I loved all the analysis that went into the MCU selection =)

[@teropiispala2576]

Now when you said your project is finished, you can move into next phase.
Few years ago I spotted your lead-screw and decided to build one. I ended up putting a control also to the cross-feed, since I was able to fit the motor into backside and maintain manual usability. Wheel turns easy enough when controller is in disabled state. Is
My first intention was just make automatic cross-feed, but features have been piling up over time. Some features are really handy and I couldn't get back to fully manual lathe.
My goal was to maintain manual working process but provide useful tool features to expand what can be done without drowning into swamp if g-code debugging and broken tools. I feel I have managed to do it, while I have scrapped several features like speech control, which I thought was good idea. It's not, because it's no reliable enough.
WhatI have now is threading, chamfer, tapers, rounding and free formed smoothed shape. I have a graph, which show the current shape cut from the stock. It allows me to pick corners and go back on spots. I can also make a shape in program like blender and load it into my sw. I can cut it directly tracing contour or slice horizontally any portion of it to rough with different tools.
In threading, I have conventional cutting with shaped tool, but also multipass cut which can form any thread shape using any tool shape. This is handy with large threads on tough materials which I don't have a tool or rigidity of my lathe is not enough for a good result. Now I can cut basically anything with 35 degree aluminum finishing insert and get practically a mirror finish on threads.
I have basic functionality running on launchpad and more advanced features on laptop. I have pulse wheels and sw controls from gui and graph, but 95% of the time I use ps4 controller. Then my moves and cuts snap into target position and I can use buttons for finemovements.
I have made multipoint compensation for errors, meaning I can make a cut, measure it from several spots and feed measured values into sw. Then at the next pass, it'll compensate the error. My lathe don't have straight rails, so there's lot to deal with. Currently I'm working to map all error sources and make automatic compensation, but that's pretty hard task.

[@tiredoldmechanic1791]

Another useful thing is to make enough perimeters around holes and slots
so the volume under bolt and washer is 100% filled.

Many years ago I had a dream of automating as much of my house as possible. Living in rented appartments and porting back old solutions quickly got old, so I bought a house. Now all my half-working projects got set back by months and years, since a newly built house is already full of 'projects'. One per day, at least the progress can be tracked.

[@leetrengove7921]

Look good mate..
One thing I did notice is the long ramp down time of your spindle-VFD. If your VFD has the ability to take a braking resistor it can really speed up the ramp down time without having an over volt fault..

[@Clough42]

It doesn't, and this is as fast as I can ramp it down with my largest chuck. It's almost worth replacing the VFD.

7 years ago I built a prototype ergonomic gaming keyboard out of plywood, plastic, screws, chop sticks, kebab skewers and hot glue. The plan was to rebuild it using aluminum profiles and sheet metal, but I never did. It worked just fine in it's Macgyver ghetto style state, so why bother.
Now that I've gotten myself an MSLA resin 3D printer, I've finally gotten around to start making a final version of the keyboard. I'm deep into the 3D CAD (Fusion 360) part of the project and have started doing test prints of some of the parts.

The answer to BOTH of your questions is this: I'm probably 80% done with a hall effect sensor to stop the carriage for the ELS, but I just can't get through the last feature I want it to have (resync). I'm humbled by how difficult real time systems are to properly program and debug.

Great job refining this ELS James! How has the adoption of the ISV57T, with the built in controller, changed the ELS panel layout and wire routing?

[@LostApathyDotCom]

You mention wanting bigger washers under the screw that hold the bracket in - what about making a small steel plate with a matching hole pattern? One "big washer" to distribute the clamping force over a much bigger area of the printed part.

[@ericmeservey8701]

Remove the cut washers, and create a thin square aluminum sandwich (top bun for the previously open-faced sandwich) plate with 4 holes in it to spread the clamping load. You probably still have the setup in the DRO. As a plus you will have more support for the Nylon bracket, and eliminate risk of pulling the fasteners through the relatively soft nylon ( which is why you wanted the washers )
Awesome video as always

[@AK-lm9ly]

James, seeing you make this progress with the ELS installation makes me want to get around to designing/building/programming/etc. a "CNC" control for my old 1911 South Bend ~10-inch lathe (originally a treadle lathe, but previous owners discarded the treadle) and get one of my PDP-8s working reliably enough to act as the controller for the lathe. So, a 1911 lathe and a ~1968-1972 computer + an ASR-33 Teletype connected together as a CNC lathe system. Magnetic tapes too (DECtapes)! ;)

A sine plate?.....try using one of those digital inclinometers....they' re accurate to ..02 of a degree.....or so they say, and on testing one a strip of paper under the one end is enough to make it indicate the difference, more than accurate for most jobs.........I have a sine table and it shows a difference with the slip of paper.....who needs gauge blocks.

It only took 8 years or so to get round to putting up lights that should be properly adequate and not occlude much of the natural light), the tool and material storage trays and shelves have been a WIP with no progress for most the time since it became my workshop, and I started work on a office computer/gaming sim chair frame I have no idea how many years ago now, and nothing managed to get done to that for many years now, but cursing when I stub my toe on the box section bits that are welded up and tucked under the workbench...

I have not read all comments in the 27 part series. What about adding a limit switch that can be adjusted to touch the carriage at end of travel? Then just stop the servo when the end is reached. That would be handy for threading and working close to the chuck.

[@colinrhodes643]

Great series James. I've just watched the whole series over the past few days. This also has me thinking. I recently saw some information on polygonal turning on the lathe with a multi head cuting head running at various spindle ratios to cut squares, hexagons etc. These were mrchanical arrangements with drive belts or gears. Your ELS with (probably) a larger motor driving a cuting head perferctly synced the spindle and being able to dial in a speed ratio. Hmmm

[@bengrogan9710]

One thing many people don't think of trying when 3d printing is the fact that you can interrupt the G-code mid print to allow you to add captive parts -
In cases like this where you mention the rigidity of the part you could design the part to have some small hollow cylinders inside to add 1/8th steel rod, then finish the print making it permanently captive
You can also do similar for the threaded inserts by leaving a hex chamber and simply pushing a normal nut in place then finishing the print

[@Clough42]

I've heard of this working, and heard of other attempts that were spectacular failures.

[@bengrogan9710]

@@Clough42 from my past experience the failures come from allowing too much space for the inserted part in designs and allowing them to be too thin walled around the inserts (usually top and bottom rathe than side wall)

Just a suggestion, if possible, it's always a good habit to keep the quill as short as possible, especially when milling. It makes the quill more rigid and you get better finish. It also minimizes stress on your machine.

@Clough42.... The Texas Instruments board you use for this build is sold out everywhere and has been for a long time. Where can we get a replacement? Thank you for your help.

[@Todestelzer]

I would use ABS/ABS+ for a mount. Voron printers are all abs for example because it doesn’t creep over time.
Nylon is good for gears for example but it’s flexible. Not good for a motor mount.
ABS will break a some point but it is stiffer and will hold his form even under load better.

[@Clough42]

Adding carbon fiber changes the properties somewhat. I tested both a CF-Nylon and a CF-ABS mount. The ABS showed much more flex immediately, but didn't creep. The CF-Nylon crept a bit over the first couple of days, but then settled down. We'll see how it works long-term. This is an excellent application for testing, because it's easy to see how it's holding up, and easy to replace if it becomes a problem.

[@Todestelzer]

@@Clough42 as far i know adding CF doesn't improve the strength but it improves printability and looks.
But I am curios how it will perform over time too.

[@Clough42]

@@Todestelzer you should probably read the data sheet for a material before speculating about what the CF does or does not do for its properties.

[@Todestelzer]

@@Clough42 I don't want to argue.
I did a fair amount of research for CF or glass fiber added to 3D printing materials.
For ME CF and glass fiber is a way to get nylon or ABS print easier and changes the surface looks.
The problem with adding CF or glass fiber is it weakens the main material in the end.
There are 3D printers how can add CF strings to the print and cut it to length while printing.
Theses parts are super strong indeed.
I am interested in how your part will perform. An update video would be nice.
Maybe you could try the part in ABS and make a comparison between CF-Nylon and ABS too?
Thanks for making theses videos I appreciate them 👍

Hi James, thanks again for taking the time to produce great content that is worth waiting for and to watch. Quick question, I am sure it will be straight forward to implement but because I don't have any experience with the TI boards, I would rather gather some info first. Will it be possible to use your code for the ELS to sync a second spindle on my lathe as with large sub spindle cnc machines. I would like to ad a small sub spindle to my machine to finish up the machining on the rear of plastic components I machine. Sure we can do it by hand but doing thousands by hand is not the answer.

RE: the bracket you printed... I've been through a VERY similar issue twice now. 1 of my brackets is now aluminum and the other bracket is completely redesigned with gussets, which is how I would have made your bracket. Gussets and a slot to slide over that mounting plate that you milled/drilled. 1 fixed mounting hole and how every many extra slotted holes that you want. I might have even made that bracket solid with no infill if I got it in my head that I had to 3D print it and put 1 fixed hole, 1 slotted hole, and then drilled 2 new holes through the backet+plate to affix it more solidly. In any case, it would have gussets. I am not saying that your solution will not work, long term, long term simple brackets like this just have not worked well for me personally.
I made my bracket slotted and drilled through the mounting plate and printed part right on the slot. It has been holding solidly for a long while now.

This one holds pretty well. It came with a hook spanner, but I just tightened it by hand. To be fair, I deadlift 450lbs without straps, so my grip strength is probably a little above average.

are you concerned with the belt being able to stretch/flex/whatever under load now that it is 2 or 3 times longer than before?

Glad to see you are human and make mistakes occasionally, just like us mere mortals 😁

And now the lathe is too small! Time to upgrade :)

My project that it's waiting it's upgrade the electrical of my workshop because if you turn on the big welder it blows the fuses (20amps)
