DIY Coil Winder - with Arduino Mega and Marlin 3D printer firmware

[@MikeSims70]

I love how you get straight to the point and you don't waste time on a soap box. I'm going to use some of this information to make a device to help me make vape coils ... i've always wondered if i could synchronize two stepper motors with enough precision to handle 38 and even 40 gauge wire ... looks like you've done it but that stepper controller looks pricey. Nicely done video - you covered all the details with efficient timing!

[@EpicenterBryan]

Awesome! Glad you found that useful. The big improvement not shown is to use a smaller diameter wire guide, and one that can get in closer. It's delicate and tricky to adjust, but a syringe type tip used for dispensing glue works great. But not advised until you nail direction and all that. Easy to go too far and bend the tip if the gcode is not fully tested first.

[@abbylersch6509]

Your practical intelligence astounds me. Awesome work.

[@EpicenterBryan]

+Dirk Hardpec Thanks! Ideally, press the button and get the banana on this project for sure though.

[@johnday7362]

Really cool coil winding project. Thanks for sharing it!

[@Sqwince23]

Thanks for sharing. Made it possible for me to make something similar. The gCOIL program was especially helpful.

[@paparoysworkshop]

That is a great device. If you made a small notch on the outer collet (where it slides onto the shaft) then you could bring the start of the wire down at shaft level and out to the end of the shaft. That would eliminate any need for tape or anything else to hold the wire. Also, you can write a simple sketch to spin the stepper motors and eliminate the need for the 3D software program and other programs. Use an arduino nano and you just need a start button. Lastly, a V bearing would make a better guide and give you more control. I can see it making perfectly wound coils. A few tweaks and that machine will be the cat's meow...

[@MrPlusses]

I love a video that makes me think of something I might otherwise not have thought about. I do hope there will be a final use video when your done. Excellent!

[@JustinHallPlus]

I'm planning to build one of these this summer. I want to be able to produce non cylindrical coils, so I'm working on trying to optimize the whole thing to be able to handle oblong bobbins (like in guitar pickups) as well as cylindrical ones, and maybe even square coils if I'm feeling brave.

[@EpicenterBryan]

+Justin Hall It should be easy enough to modify the mechanics to hold oblong bobbins. Then all you need to do is measure the circumference of the oblong bobbin with a wire or string, divide by Pi and use that calculated value for "diameter of bobbin" in the software.

[@JustinHallPlus]

EpicenterBryan Thanks for the advice!

[@AlMg1SiCu]

"most of the channel subscribers won't be interested" Video gets way more views than any of the others :) Nice work, looks like with some small adjustments it will work fantastic!

[@xFuaZe]

I'm not sure if it would do anything. But if you know when your "coil part" has made a full rotation, you can move the head with the size of the wire. This way it would be exactly the right spacing... I'm not sure if it would work in practice, but it doesn't seem to do such a thing in this video.

[@squishy312]

I enjoy all of the videos. However, you should make a channel that is dedicated to little projects like this. There are a lot of us out there that are also makers, and it helps to see what other people are doing. If you had a dedicated channel, you could do record more of these projects. Keep up the great work!

[@ShenghongZhang]

I think the shaft moves a bit slower on the axial direction than the cable climbs in the microscope video. Probably need to tune that a bit?

[@kamboora]

so nice job, congratulations, i just interested to know what is the stepper motor drive "minute 9:05" brand?i'm doing such jobs that i need a driver for my steppers. thanks

[@EpicenterBryan]

+Ibrahim Al_menesy I got it from this guy on E-bay... stores.ebay.com/SAVEBASE

[@bulletproofpepper2]

very nice work. i was looking for Arduino programing tips. if cut the cone sides flat you bring the nozzle closer to the work. thanks for sharing.

[@keili0511]

I can't find the Gcoil Software anywhere in the internet, can somebody provide a link for me? Great video!

[@thebeststooge]

A lot of slop in that and over winding. They do sell 0.1mm nozzles for really cheap but I would suggest a stainless steel nozzle so your opening doesn't enlarge since that copper is abrasive to the bronze nozzle.

[@LynkedVideos]

Keep in mind that the wire is coated in enamel. I wouldn't want to use either brass (not bronze) or steel for the guide. This is a great application for acetal (polyoxymethylene). If that's not available, then machine something out of some type of nylon. PCB drill bits down to 0.3mm are dirt cheap, and a cursory search on Google turned-up a 0.15mm bit.

[@sublimationman]

Very cool. Looks like you needed a little more speed on the sled back and forth and the there would be less chance of overlap like it was doing in the video but it's very close.

[@tonyhodgson6744]

That's ingenious, nice one.. I've been winding a lot of flyback transformers and that device would have been so much easier than my winder....

[@crikycrocky]

I like the way you have put this together. I know now in KZbin terms this is an old project but should you ever revisit it or do something similar, regarding the difference in nozzle hole size compared to the wire diameter, you may find that due to the nozzle being made of soft brass you could use a punch to peen the brass over reducing the diameter of the nozzle hole. This would have the added benefit of work hardening the brass in the vicinity of the nozzle opening itself.

[@samanthaautoengineering8792]

dear sir iantm Samantha from sri lanka. this very imported this tome but I cannot found this parts in sri lanka. ple help find this parts to me

[@ericjohnson8482]

Your coil will have some issues and not output as well as it would if the windings were laying perfectly on top of each other, another thing you might want to look into is vacuum impregnating the coil with a polyester or epoxy resin.

[@GonzaloCobos]

Awesome winder, but not quite perfect coils! I made one of those some years ago and I ended up guiding the wire with a wooden stick, specially to fix the end of every layer and the beginning of the next.

[@The-Master-of-None]

Please please share your plans and instructions how to do this in detail. This is such a good build. Thank you. :)

[@wbwillie]

How would one have to set that up to wind guitar pickups?

[@FirstIrishKing]

Great video, Bryan.

[@hemashri]

It's a good work for those interested...

[@mikesfarmmikesfarm3977]

I know this is a old vid, but I am a arduino guy as well as a freeze dryer, prepper etc. Are you making electro-magnets or solenoids ?

[@szekerespista3758]

Congratulations! Can you make one for sale? I am interested! Thanks

[@AuralVirus]

using a suitable gauge syringe's needle, either inside the 3d printer nozzle or on it's own may cure the wandering(?)

[@driversteve9345]

Awesome job man! It's not perfect but close! With a bit more tweaking, it will be as good as a professionally manufactured coil! When can I buy your winding machine? I want one! LoL!

[@abelestebandelatorre1052]

Great proyect! Suggestion: Remove the 3d printer nozzle guide and add more distance between (10 to 20 cmts more) both extremes of the wounded wires. You will get a professional finish. The key is to keep wire a little tight while wounding

[@pstoneking3418]

Nice job. Very interesting.

[@shyleshsrinivasan5092]

Brilliant ! Thanks a lot !

[@dominictisdell4091]

Hi Bryan, as per a couple of the recent comments, the Gcoil software server looks to have died. Would appreciate it if you could post it somewhere for us. Thank you!

[@PRPabst]

Very good project. Did you any changes to the original Marlin firmware? If yes, can you share it? I what to try it. I need to wound like 2 to 4 thousands turns.

[@paulrautenbach]

You might try a (much) longer distance between where the wire leaves the nozzle and the shaft it is winding onto. You should find this allows the wire to track back and forth along the shaft by itself, guided by the last turn already wound on the shaft. That is, it will give neater windings and be much less dependent on the position of the nozzle. You may even find it unnecessary to move the nozzle for narrow (ie most) coils.

[@EpicenterBryan]

+Paul Rautenbach what ended up helping was to pinch the wire with my fingers as it spooled into the delivery tube. It helped keep the wire centered. But replacing the nozzle with a smaller one is the plan. I found some on E-bay.

[@khofhikhof1503]

Friend i need speaker coil winding machine

[@PerryCodes]

Is it not important for the coil to wind evenly?

[@Arek_R.]

You can buy 0,15mm dia nozzle.

[@bzhmaddog]

Nice Project. Quick question though. Why not using a standard Ramps shield ?

[@EpicenterBryan]

+Cédric MARTIN I'm using parts that are actually for another project (cnc plasma cutter). That project needs to move faster with higher torque so I'm using a 24V power supply and the ramps shield can't run at 24V. Although I did use a Rumba board one time at 24V. It literally burst into flames the first few minutes.

[@paul.alarner6410]

whynot give a link to the modded code ? .

[@retroatx]

This is very nice!

[@NMETSGChan]

If you would increase the lateral movement speed by 25% you would get a better coil since winding uniformity gives the best result.

[@rolandosalgado1552]

Very usefull Project , thanks for share !!!

[@Counselor77]

I love it, great work !

[@wa4aos]

Glad I found your site.. I have a need to build something similar to repair coils on mechanical filters. You explained this very well and gave me some excellent ideas that I would have had to attempt to figure out.. Thanks so much for sharing your knowledge and this very slick project! I will be using 40 gauge wire or possibly 44 gauge litz wire that will have a freq coverage in the 450KHz range, which is the freq these filters operate at. A few quick questions. Are you experiencing any significant backlash in the X or Y planes? That track looks like an excellent way to go. Did you find a source for a finer nozzle. I was considering using a small piece of Teflon stock and drilling an appropriate size hole with small wire bits ?? Again, thanks for sharing this project. I have been looking online and as well as youtube to get some viable options and got the best ideas from your project. Best regards, Glenn DSM Labs (doty com)

[@EpicenterBryan]

+wa4aos Yes, I found there are smaller nozzles on E-bay. No back lash issues with that leadscrew or the delron nut.

[@ChristianRThomas]

I plan to do something like this in the not too distant future. I know more about this topic from the electrical/magnetic perspective than I do from the motor control angle. Like you I have thought that winding on carbon fibre would be a good option. I have to say I'd be less keen on Aluminium as it's conductive and is going to invite losses through eddy currents (carbon of course is also conductive but nothing like AS conductive). Maybe those losses are going to be insignificant in comparison to the resistance of the wire but I would suspect they'd show up on the hysteresis curve rather than in an L + R transfer function. Since you are doing it on such a small size (though I now see I am two years too late) you could use sewing machine bobbins as your former. Finding decent and cheap bobbins on a larger scale is something I am finding nearly impossible, even from China. I was also going to suggest using epoxy - probably with some filler to avoid drips - rather than nail varnish. Having the bobbins could help you not get the glue on your collets and shaft, which might be hard to remove if you leave it too long. But this video has been very useful in helping me formulate my plans so thank you. My next step is to find a decent tensioner mechanism that will do 1.5mm wire - other end of the scale from you.

[@vader3t3]

Wish I had this for my school project...

[@patprop74]

That was very interesting, if you do want to make this a cost efferent project, you could replace the mega with a uno( 4$ to 6$), by adding a grb shield (4$ to 6$) with two a4988 stepper drivers( 1$ to 2$) each, and add a few different mounting plates, so that not only could you spool your tiny coils, it could also be used to coil recycled magnet wire. I am sure that 0.1mm wire, must cost a fortune, you could easily find them on many different transformers on old boards. but I am wondering, what do you plan on making with these coils? especially that it with an aluminum core .

[@EpicenterBryan]

+patprop74 The end use for the coils is in my home made stereo record cutting head. Those are the feedback coils and push rods where links will go to connect to the stylus holder.

[@KiSwiSje]

thank you for sharing this, i found it most inspiring

[@bumbarabun]

You can easily find 0.2mm nozzle on amazon or ebay :) Not sure about 0.1 but it could be too tight.

[@hyperhektor7733]

You said you need only 2 perfect Coils. Too my this setup looks overengeneered but still doesnt give 'perfect' results. I think you get the job easier done when you programm the arduino direct to controll the 2 stepper motors. use the microscopt to determine the windings per round and then just put it in the arduino sketch together. To improve the accuraccy you need a better wire guide. The nozzle is too far away. Better use a small pipe* and go as near as possible to the coil body ( depends on the end diameter of your coil).* You can buil the pipe with a 0,3-0,5mm drill with hardwood or plastic. Another idea is: use a sewing needle and bend the end of it to 90 degrees (heat it maybe). this could work as guiding arm instead of a nozzle.

[@sspence65]

This would have been handy when I was making coils for my axial flux wind turbines!

[@Sqwince23]

thanks so much. this was what I was looking for!

[@EpicenterBryan]

Awesome. Glad you liked.

[@SMT1hanel]

[@johnnyplays2843]

Quick question does uarduino or however you spell it work with a MacBook

[@cmguitar50]

yes

[@GasNBullets]

Ok so what are you using 200 mini pickups for??

[@EpicenterBryan]

Well, they were used to measure feedback for the movements of a stereo record cutting head I was developing. Several years were spent on that project, and it worked pretty well once rebuilt. But the head was too big and I could only cut 1/2 a record with that version. The videos were private - only for a forum where people were interested in the topic. I might post one where I blew up the head demonstrating how the feedback was working. That one was pretty interesting... Who knows. So many projects, so little time.

[@butchweise6056]

A lot of people DO. care Bro!! Thanx for the vid!!!

[@Livingstonshoedios]

fascinating (no sarcasm what so ever)

[@hunter00047]

Good work but over complicated producing in-perfect coils, only worth it if you wish to produce tons of coils, then a multi-bobbin winder would be better. I knocked up Tesla secondary coil winder with some wood a spindle and cordless drill in 1 hour with perfect non crossing turn. The golden rule start simple then improve as you go.

[@wa4aos]

Your point?? I think the video was very helpful with lots of good ideas that have helped many of us. He took his time and explained the mechanical and firmware issues that are confusing if you have not played with them. He was winding .1mm wire and that would have been a total disaster on a cordless drill arrangement as you described. He also needed a somewhat accurate turns count for his project whereas your tesla coil simply gets more output voltage as you increase the primary vs secondary turns ratio. Sounds like you are ignorant enough that you should not criticize someone else's work when its obvious you have too little understanding of what the author explained. Zzzzzzzaaaaaappppppp to you and your tesla coil.

[@hunter00047]

Wrong Tesla's to work correctly need counting as they work on resonance not just add turns like you say,+ I wound thinner than that on a cordless with speed control.

[@sweatkamran]

Hi nice project i like to make similar like ur project Can u help me

[@PerryCodes]

Good info. Terrible audio. update: at a certain point, the audio is okay. looks like your mic gain might have been too high in the initial segment/shoot.

[@Sevendogtags]

Audio was fine for me, maybe it's your speakers.

[@PerryCodes]

Nope. Not my speakers. It's clipping all over the place within the first 10 seconds.

[@Sevendogtags]

Perry Codes Well whatever it is, it's you. Drivers, sound chip etc... Cause it's fine for me. And don't see anybody else complaining about audio here.

[@PerryCodes]

Nope. It's not my speakers. It's not drivers... sound chip... So either your speakers suck or you simply aren't perceptive to digital distortion. Because it's in the audio. And I've heard it from several different computers/speakers. Turn up your treble. Turn up your volume. And listen to the word "Epicenter" in the first several seconds. The clipping is on the left channel. It continues like that for quite some time, but eventually goes away ... probably during another take with the mic gain turned down.

[@Sevendogtags]

Perry Codes Lmao, you're clearly mad! xD FYI, all modern computers have sound chips! You're thinking sound cards, that's 80-90's-ish unless you're gamer or a professional artist. Ever heard of Realtek?! They're in like every other motherboard on the market! It's called a sound chip. Also, I had heard what you're referring to now that you explained it more. I didn't think of it much cause it's no big deal at all! You were making such a big fuss about it like saying audio was terrible that I thought it must be something way worse. But clearly, you're just a self-centered jerk.

[@ahbushnell1]
