The last few minutes of this video is why you are our favorite DIY youtuber.

Jeremy, my daughter is now in her 30's and renovating her second house " by herself". I have to hope that letting her help as a child influenced her confidence to think through any challenge.

There you go again, sharing with viewers more than just how to do the electromechanical 'stuff'. Your kids are blessed to have a dad like you. 👍

1st: If you didn't want to spend the money on a RJ-45 break out board (those things get expensive), and don't want to worry about breaking a custom cable, you could make a short length of custom wired cable that goes from the component to a bulkhead connector in the panel side. Then run from the bulkhead to the component on the machine with a normally wired cable. This way, your custom wired cable is safe inside the cabinet and you have standard cables outside in any potentially dangerous areas, without the expense of the breakout board. The other is that you were showing wiring all of the switches in parallel for not being able to detect one of several NC switches opening. If you wire the NC switches in series, you can detect one of several NC switches opening. Further, for safety critical applications, both the NO and NC side of the switch should be monitored as NC contacts can't detect shorts or failures to open and NO contacts cannot detect wire breaks. Remember, a damaged cable doesn't always fail open, sometimes it will develop a short between conductors, especially if it manages to flex and chafe through insulation. Wire the NC sides in a series loop, and wire the NO sides in a parallel group. The control should monitor for both the NC and NO circuits to be in the "safe" state. Probably overkill for limit switches, but a must for multiple e-stops or palm button controls.

I laughed out loud at the ask me how I know part, because, ask me how I know?

I use to love to watch my dad build things. I learned so much stuff from him like this. Good on you for involving your children.

Geeze! You’re a creative polymath! I’m glad you’re teaching and sharing what you know. From what I see of kids today, very few are ever even exposed to the kinds of knowledge you have.

I'm so happy KZfaq recommended this channel to me. such a cool dude with really interesting projects. One of the best DIY engineering channels I've seen, definitely deserves more subs.

Re: the soldering, the melt-and-dunk method may not be wise: generally you want all the metal involved to be at the same temperature to prevent a bad joint ("cold joints" can look and feel solid but not actually be soldered.) If the wires can't take the heat required without melting their jacket, you can separately tin them (well), and then do the melt-and-dunk, but maybe hold the iron at the joint for an extra second or two to make sure it's all bonding.

This is an awesome video series. I just found your site today and I have to say, I truly enjoy your delivery and content. Thank you Jeremy. I look forward to watching some more.

Jeremy, I discovered your channel a week ago and it didn't take long till I subscribed. You are awesome, I like the way you keep it within a range of understanding and leave the rest to us to figure out. That makes your videos so fantastic. You explain and teach us so much yet leaves us with just the details to figure out on our own for our personal application. I think it's safe and so smart. By the way, when you said "ask me how I know", I knew the answer to that because I did it too, more than once. lol... A month ago I was given an old industrial copier machine and an old industrial color printer. I took them apart and kept all I wanted, maybe a little more. Later on is when I found you. I don't know what I'm going to do with all those small stepping motor, compared to the large one you found in that copier machine. If you don't live too far from me I may ask you if you want anything I don't need and I'll send them to you. I live in central Alabama. I have tons of parts I hoarded for a long while which most I probably never use. I never sell anything, I give it away or I throw it away. I also dismantle a threadmill and kept the parts, now that I saw how you made a bench power supply out of it I need to find the box where I put all that electronics in. I want to make one just like yours, it's awesome... Thanks again for an awesome channel. Keep the great work.

As for soldering, if you take a small piece of thin solder and twist it inline with strands of the wire, you can then put the wire into the cup and hold the iron on top of the wire and the solder will melt and make the connection. I have wired a lot of solder cups.

You're making great progress. Sharing your hobby with your kids- making memories they'll recall years from now.

Man, I cant describe to you how much this video helps me. Please please do more in videos like this. Super big thanks.

What a great video, especially with your family. Sometimes you just need to step back, take break so your mind can clear n figure a solution to what is a speed bump inyour thought process. Having yourkids come in, ask some simple or even crazy questions, to get you over that bump and figure your way to move along. You are a remarkable person, n a great dad. Everyone is learning, in more ways than one. I feel better now just watching. I learned something. At 66 some times its hard to teach an old dog new tricks. 40 years as a residential journeyman electrician, now retired, a breath of fresh air is sometimes what you need. Thanks so much for sharing, n wish more parents lived life like you. The world needs more parents like you.

You are my new go-to channel for CNC info. Thank you, brother. Much love!

You are a fantastic parent. I feel the best thing you have taught your kids is to have an inquisitive mind! You have also taught them by example to be lifelong learners and problem solvers!! Great job!!! You are a great role model for all dads!!!

Jeremy, it is very fun and refreshing to watch your videos. You take pride in your work and enjoy what you're showing. Keep it up and thanks for the quality content!

The problem with limit switches that you comment is the reason why in the industry it's so common to use current signals instead of voltage ones. The 4-20mA protocol is the most common, in which 4mA is logic zero, and 20mA is logic one, but if you read 0mA that means the signal path (or the sensor) is broken. These signals usually just pass through a resistor to generate a voltage and that voltage is then assigned a logic value.

You are one of the finest in explaining these concepts to the average Joe like me. And I’m sure students already in the field (ing) love it as well. Thanks for all you do!

Hey! I know I'm a bit late commenting here but I came back to your channel for a project to make myself a CNC mill and your reasoning for using NC limit switches is a great point. I may actually pass this on for some of our proprietary machines at work!

For someone who wants to have a try/play with CNC I would recommend getting an Arduino UNO and install GRBL on it, then you can just use a couple of very cheap stepper motors with control board ($3 each on ebay) cobble together something very basic to move a pointer around and then experiment with what you can do with the software. Making a full size CNC router is not more more difficult than this, just needs bigger stepper control units :-) To quickly create some gcode to try on it have a search for JSCUT BTW - Have a look at GRBL on an ESP32 - this is really impressive

Everyone - please click the link to show solidworks that we appreciate them sponsoring jeremy

So glad to see more content from you!! As for the encoders you want to get RJ45 Crossover cables.

The inside of your box is very organized and clean👍looks really well made.

You can Series the limit switches in NC configuration.

Thanks Jeremy for your videos. Im getting my utube degrees while recovering from spinal fusion in my back. Lol. I admire you for getting your children involved with your passion to teach others. They will definitely remember and cherish the time you gave them.

Your attitude towards your kids is absolutely beautiful.

Congrats on 200k Jeremy! Nice job!

Jeremy, I really enjoyed your story about kids in the shop. I'm a Dad and didn't always follow that model, and that's my fault. Technical skills in our country are fading, except with Dads like you where they are expanding. I watch a lot of your videos and have sent many to friends and my Dad, great channel!!

Great video, Jeremy. I'm really enjoying this series. One note about wiring your quick-disconnects. Your description of soldering the solder cups is a recipe for cold solder joints. The wire should be fixtured in the solder cup first, then be soldered in place. If you fill the cup with solder first, then by the time you insert the wire, all of the flux will have burned off and the solder is likely not to properly wet the wire. Also, you can use normally closed limit switches on a single input by wiring them in series. This way any one that opens trips the controller.

Inspiring content Jeremy. Currently making a CNC plasma table myself. Keep making 'em!

I like how you explain things. I have bought most of my components for a lite duty cnc machine. I looked in to a few blog sites for the wiring but the vile comments by troll groups was relentless. I think its a generational thing and sharing information unlimitedly to the best of your ability at the time of discovering is a fresh way for working. Thanks for sharing.

Great video! You're a wonderful teacher.

Half way through and I already love this channel! Thanks Jeremy

The best instructional video I have seen. Thank you!

I've had a need to reverse the RJ45 or RJ11 arrangement in the past and because it's a specialty cable I used some yellow CAT5 snipping from the bin. Because it can potentially damage components that are not made for it, so I tagged it as well but outside the raceway so I can follow the yellow to trace the route from component to component. I love that you encourage your children's interest in tinkering, that sort of thing changes their brains at an early age and can lead to a lifetime of curiosity and critical thinking, much respect Jeremy.

I am glad I found your channel! I enjoy seeing your videos and the way you explain what you are doing. Thank you, keep up the good work and God bless you and your family.

Always a pleasure watching your videos Jeremy. Keep up the great work and keep em coming.

Bro awesome video. You are the perfect teacher . I learned lot of your youtube chanel.

Very informative video, I especially liked the safety measures. Deserves much more views!

You are a natural born teacher! Thanks for sharing this awesome project!

Great video. Thanks for walking us though each component and step. Very informative and helpful.

Woah my head hurts. I like your simplified descriptions makes researching what I need to know easier. Thankyou

I'm going to take a butchers at Solidworks tomorrow evening while I'm out in my small workshop. It's nowhere near the size of yours.. I'm rewatching this video again right now Jeremy..LOL.. I love the information u put into this so I need to watch it a few more times. I will take notes tomorrow and work from there.. Thanks again pal..

Great job on the video. Description was easy to understand. Great engineering. Congrats on sponsor! Mahalo for sharing. : )

About the “eathernet switch” you made, Siemens makes connectors that you cut the cord and you can wire the connectors any way you want. You don’t need to strip them either, you just line them up and clamp it together (the connector and the wires are everything you need.) it’s what we do at work for this sort of thing. I’m very impressed with how compact you made the control cabinet! Although it is a bit messy, but it’s not going to a customer, so works for me! 😂 haha

You have amazing videos! Came here from smarter everyday and am loving it!

🇺🇸🇦🇷 One of the things that I most liked is the fact that you teach your kids about it. There are some kids that know crap of NOTHING because their parents entitle them or “ don’t have time or protection them from I don’t know what “ Very knowledgeable this is not the first time I’ve seen your videos.

Jeremy. i am so happy to "meet" you on KZfaq. you are doing a terrific job. please keep up all the informative videos, great content, and hard work. so honest: "ask me how I know !?!" 'A-Plus'...jumping the 80volts. just like jumping 12v on the back of a gauge cluster. but...your information..."makes my old head spin". any, and all, negative comments are just (know-it-all =) "yada, yada, yada." so very proud of you and all of your hard work. very best to you and yours. walt.

love the electrical aspects! keep em coming!

Amazing work on this video.

The rj45 you need is a crossover ethernet cable. Or for 20 dollars or less on Amazon you can get a crimper kit so you can make your own rj45 cables

This is a great project I'm glad you're doing this

LOL... "Ask me how I know" Honestly I can not even remember the number of times I soldered connectors together and then had that DOH... Moment!

Well done, Sir. You’re an inspiration.

Great video! Love seeing kids in the shop.

As always a very well made and interesting video. Thanks.

To your comment about the kids in the shop- Sage and Well said my friend! If you can't explain it to a 7-10 year old to the point THEY understand it- then you dont know it either... BRAVO Mr. Fielding!

Ahhh electronic controls....fun stuff. Use this all the time in food processing / manufacturing.

Excellent sir. Well done. Thank you. Keep up the good work.

Great content! Great Dad to those kiddos keep up the good work!

Love the bonus footage. Man big brain on this one and I'm here building a $100 CNC.

The last 2 minutes was the best!

At 12:47 you say you can't wire multiple normally closed switches together if you want any one of them to cut the power. Your diagram showed the switches connected in parallel, so any one would bypass another. But, if they were in series, they would function properly. With positive "OR" logic, we want normally open switches in parallel. With negative "OR" logic, we want normally closed switches in series.

The rj45 connector stuff reminded me of making crossover cables for home lan setups for gaming parties we used to have back in the days of 28.8k internet connections.

Love your videos! this is a cool build!

I really love your videos, including this one. But for me as a German it is really funny how you say "DIN". DIN is a german abreviation which stands for "Deutsche Industrie Norm" which translates to "German Industry Standard" in english. The "I" in DIN is a long vocal so it should sound more like "dean". 😉

You're a beast, man. Solid work.

All good stuff. 🧠 I like your explanations and visuals. And cudos, (Dad & kids) for the fun🤺 and teaching moments 🎓with the kids. 👍

You're a great man ,thanks dude.

When I worked in engine test and development, a lot of our equipment used RJ45 connections too and we often had to have "crossover" cables made so that Tx would talk to Rx properly without the use of a network switch. Usually tried to use different coloured sheathing to make it obvious

Great video, Jeremy. Beginners will really benefit from your experience. A suggestion: It looks like you are borderline on the 50% open-air rule for an electrical enclosure. You might want to look into putting a couple of air circulation fans in. Would hate to hear some of your components overheated and fried because of overheating. Keep up the good work. Cheers.

You're a good Dad Jeremy. Thanks for the video.

Idk if you'll read this, but I think the off the shelf solution is called a crossover cable. Its basically an ethernet cable that isn't wired 1 to 1 on both sides if that makes sense. I think it was meant so that if you connect two PC's together, they send data to the other PC's receiver pins, rather than their sender pins. This has been rendered obsolete by modern computers. I think. But you don't need me to tell you that your method does the job just fine.

Very good video thanks

You are a genius Jeremy. Thank You so much.

Hi Jeremy, It is so few times that I know something that might help someone that it is almost nonexistent. I have a tool that makes up "RJ45's" because I used to run cables from one room to another and I needed lengths that were not available. This tool would allow you to make up a cable that went from one rj45 to another and had the wire configuration that you need. The tools are not that expensive and you can get them from "Maplin" and most likely other electric supply stores

Alternative method to the RJ-45 'translator' solution you showed: If you have an RJ-45 cut/crimp tool then you can just make your own custom wire by reordering one side of the connectors properly. Then you don't have to use the 'translator' . Both things take time though, and this solution would require that you have the RJ-45 Crimp/Cut tools and spare RJ-45 connectors as well as the networking wire needed to make your own custom RJ-45 connection. I have those things but most don't.

this video needs 10 thumbs up, great video!!!

Super logical. I always appreciate your good work. Patreon dollars well spent.

Brilliant fabrication and broad set of skills.

Fantastic! Keep up the good work (being a dad). Also the project is great too.😀

Great job

Thank you for this video....great work, great video......

Smile on my face Made By You Jeremy! Works well and what I needed to Fit my day! ~ Thanks! note: I don't make or really understand all this, but I DO Know ~ W0W! Look how much you've done! I Enjoy listening about ALL created. Hold Close the Sound a Energy of Your Kids - They grow up too fast! Hi to them & 'Mom' there as well! Cheers to All : } ~- *

For changing the pin order of the RJ45 connectors, you could use a 110-block or a keystone jack. You can even surface mount the keystone jacks on the outside of your box to use as your quick-disconnect.

Jeremy, excellent video explaining the POWER Supply for a CNC machine. I would hope you explain couple of things about VFDs. 1. Which is the better VFDs to use for especially at home, since the homes in the US are single phase 120/220. I have read that getting a spindle that is 2.2Kw and 220 volts is not good to run on a VFD that takes 120/220 volts single phase and converts it to 220 volt 3 Phase. It would great to hear your point of view since you have done excellent videos on various motors. :)

WHOA. Your comment on the limit switch closing the circuit means the switch is pressed close (or normally open). Limit switches should always always be normally closed, so when they fail, they fail open and your motors don't drive whatever into the frame, burning out the motor and doing damage. You're my new favorite youtuber, BTW. I just don't want your beautiful machine to be able to tear itself apart.

When using break-out boards for Ethernet/RJ45/8P8C connectors, be aware that those types of connector are usually used for data that is somewhat sensitive to electromagnetic interference (both from outside noise and from cross-talk between wires of the same connector), with the problem usually being mediated with the use of twisted pairs of wire. If you don't know much about the data going through, assume you need to use twisted pairs after the breakout, or if you can use tiny wires, cut off the connector and use the pretwisted pairs inside directly.

Hey man, love your videos, curiosity only - you said in the part 2 you’d say how much it cost you in the next video... didn’t see that...?

Hi Jeremy, first of all, love your video's. And for the encoder, i like your solution. However, the first thing that comes into my mind, that also would be cheap, is to cut off the connector and put a new one on in the right order. This would save you some space. I used to create these cables all the time, working in IT. Inside are just the 4 pairs of cables and you can easly rewire them to a different order. Also i would recommend to use sftp cable as it would protect the signal due to the insulated shielding.

love the end :)

Jeremy, heard you on NDQ today. Excited you're working with SED.

Amazing!

You show the multiple NO in parallel, you can do multiple NC in series. It is just a bitwise AND or OR arrangement.

Nice video. I like the advice about having your children out in the shop. I did have a quick comment about your limit switch NC vs NO answer. I hadn't thought about it before as my controller wants the switches NO. There are two sets of pins on the controller for each axis. They are the same electronically and the controller figures out if the positive or negative switch was tripped based on its movement. When you said that having NC switches connected prevented you from having multiple switches connected, that isn't true. You just need to wire them in series vs parallel. That way if any one of the switches or connecting wires creates an open circuit, the controller will stop. I like the idea of sending a positive signal from the switch vs no signal and assuming all is good. The odds of your wiring developing a short when using NC configuration seems very minimal vs. in the NO configuration having a wire or connection break and always sending an all clear signal. I am going to check my controller to see if it will allow the NC signal and if it does, I just may switch which terminal I am using on the switches. P.S. I send a link to your video where you were showing off your new CNC machine and he has been drooling ever since as he would love to have something like that in his shop. :-)

Thank you sir.

Very good 👍
