very excellent!! for the counter and stopping the traverse motor if you put an encoder on the winding motor you get a known numbers of impulse of each rotation of the bobbin, an with this you can stop the bobbin motors and the others too. but for now the project is amazing, a very good work!!
I love it. I'm currently building a winder out of an old sewing machine and love the idea of a manual traverse system where you do not hold the wire and traverse rather I manually traverse it by a crank wheel rather than a cnc. Thank you
Love it! Ideas . . . 1. Eliminate the stepper motor and use a servo to transit the bobbin. 2. Instead of counting turns, why not just measure the length as it is wound. 3. Use a microprocessor (arduino, etc.) and do away with gcode. 4. For the software, include settings to mimic well known pickups. 5. Use a touch screen to control settings. Maybe a fine tuning rotary digital encoder would help with this feature. I mean, if you're gonna write software anyway . . . I'm just getting into guitar building, you have been a great help! I love to improve processes and troubleshoot :). And do everything myself where possible!
Heyyy! Me, after viewing one of your shares, Smiles Always!!!! Well done! I'm not scratching my head yet but I'll surely get to that point, thanks for your guidance!
Interesting stuff.... i am still partially building the older version, some stuff still not done, and doing just by checking the previous build videos. Checking this one i also can make one suggestion to the build list, 3d printer file for the plate for the pickup coils.
Having the counter separate from the software is a nice independent verification that you're getting what you expect to get. Things like that just feel good to me even if redundant. Great project!
I used optical pickup into interrupt pin on my Arduino to implement the counter. I used a basic LCD display to display counts - and I added a gauss meter to my winder as well. No CNC though.
Hi Chris!. That's a pretty slick looking machine you've built. My prototype has a few things different, but many similar. I'm not using G-code at this point, as I've had no experience with it. (If I build your CNC router that will change, LOL). I've tried some code for this written in a variation of Python, and also a different idea using a piece of open-source software that runs in the Raspberrian OS. (I had an unused Mark 1 Mod 0 Raspberry Pi board waiting for a job). I think I mentioned earlier that I was experimenting with wire tensioning. I came up with a device for real-time "dynamic wire tensioning" - it makes small adjustments to the wire tension based on bobbin position, wire gauge, winding speed and a couple of other things. I finished the "test model" of the device only a few hours (literally) before my accident, after trying a few different mock-ups. So it hasn't been fully tested and won't be for some weeks. I'm wearing a large and kind of awkward shoulder-fingers cast right now; as a result I'm down a hand. But, I think the gadget may work out OK, going by the initial trials. It's not an overly complicated system in terms of # of parts, or control. I'd like to send you some info for you to look at, once I'm back in the workshop. If you find it to be a useful addition, please feel free to use it, or include it with your plans. A bit of payback to you back for the many hours of priceless tuition your videos have given me in the luthier's art. Anyhow, your new machine looks like a really slick setup, and I'm looking forward to going through episode 4 (no internet in the hospital) to look at your new traverser. Many thanks for sharing this project - it's really exciting to think about the possibilities a system like this could offer.
Looks cool. I think you should be able to generate a G Code file that could accurately wind the pickup to the correct number of turns and have it shut down the motor.
In theory, yes it's possible. In practice, however, the math and its required coding get's extremely complicated. The challenges include accounting for different bobbin widths, the speed of the traverse needed for achieving different scatter winding patterns, and the need to ramp up the speed of the winder motor at the start of a coil winding operation. Thinking about it gives me a Python headache. Right now, it's much easier to cancel the g-code feed when the counter shuts off the winding motor.
So, if we purchased the plans and you make updates to the software, is there a way to receive updates or will it require an additional purchase or re-purchase?
Hi Chris, how do you handle wire towards the end of a spool? Let's say you want 5225 winds but you don't know if that much is left on the spool. Do you go for it and if it runs out early just scrap it? Do you not waste your time and just move to a new full spool? Maybe create an underwound pickup that just uses whatever you have left on the old spool?
I cross my fingers and hope to have enough wire. If I'm pretty sure I won't have enough, I'll grab a new spool. I could calculate how much wire I'm using based on length or even weight, but that seems a bit nerdy.
Very cool, I’ve built your CNC machine it’s really awesome I’m looking forward to this one as well. By the way, where do you get your pick up Bobbons and flat work/magnets and materials from? I have a laser cutter and 3d printers but just just seems like be a lot easier just to buy them in bulk? Thanks James
Looks awesome, I was contemplating buying one of those CNC coil winders that are like $575 from ebay but this looks like a better option with the scatter wind ability of the transverse stepper. Do you have any rough estimate of cost of parts? Do you have an idea what the maximum winding RPM can be? I had bought plans for the previous winder you developed but I think I will go for this build instead.
Don't know the cost. I used a lot of parts I already had. With the software I am working on, the rpm has to be limited to 1200. However, that could change in a day. I have ideas about this.
I will say I've been pricing out his non-cnc pickup winder using parts direct from China. Comes in just under a $100. With a lot of extra screws and such that you can use for future projects.
My main issue is wire tension. Too much, break, not enough loose. Any way to digitize it to remove iterative efforts? Got MOJO tool but still have to guess at tension.
I considered adding a force sensor to my tensioning mechanism. That would provide feedback in grams for how much the mechanism is squeezing the wire. I may explore that in the future, but for now, I have the tension set to yield exactly the target resistance I want for each bobbin regardless of the wire gauge. Of course, I broke the wire during my first three tests, but after adjusting the tension, I got the tensioner set just right.
GREAT project and awesome videos. Agree w Matt below that presets for historic pickups would be awesome. Those presets could be sold separately as the research is available.
@@HighlineGuitars It does beg the question how much difference do winds, wire and magnet type/strength all make in the final result. A device like this certainly makes experimenting with different magnets/components easy since the wind is identical.
Looking forward to this one as well
very excellent!!

but for now the project is amazing, a very good work!!
My solution is sort of a poor/simple man's approach. But it works!
Excellent winder you've created!! Chris ya never stop coming up with practical tools/methods for us to try to absorb!!
I am a big fan of your work, I will be happy to purchase the plans for it once they are available
Very cool. Great upgrade from the last winder which in itself is a great device.
Chris, it's amazing all you do! your channel is truly never boring
Nicely done! I will buy these plans when you make them available. This version will make for more quantifiable experimentation. Sounds like fun.
Nice job. I looking forward to seeing your final version.

Great work Chris, I am glad your doing it math isn't one of my best subjects thank you for sharing.
Chris, this is an amazing machine! Well done! Very inspirational!
Thanks so much!

Very cool Chris. Here's a crazy thought- what about presets to emulate historic winder traversing ie. Leesona 102 etc. Thanks for your great videos.
The only problem with presets is that the outcome would be purely subjective.
Absolutely fantastic!
Damn I'm very excited for software update that you are talking about!
excelent!!! I was waiting this for a long time, thanks Chris

I haven’t made any updates to the software. There hasn’t been any reason to.

Hey Chris,
Are you going to make plans available for this? Buying a cnc winder off the shelf is surprisingly hard.
