    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.

    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.

    • @ghwizz

      I can't make a straight box or many of the other things you find easy but I have been soldering for 40 years (!) and I would respectfully suggest you add a technical correction to the description as described above. Otherwise you run the risk of a bad joint or worse - an intemittent connection which is a pita to diagnose.

      If you put your NC switch in series, any toggled switch will open the circuit, thus telling you that a switch has been triggered...

    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.

    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.

    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

    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.

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'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.

    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.

    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.

  • @RangerM98
    @RangerM98 4 ปีที่แล้ว

    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.

    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.

    Just a late comment. Using the control power transformer, as you have done, is best practice. For those who don't understand why it will become readily apparent when you source power from the same power panel as your air compressor and plasma cutter. When the air compressor and/or plasma cutter power on there will be a voltage spike through your control panel that will likely disrupt operations. To anyone who doesn't know a control power transformer will mitigate/eliminate voltage irregularities from the primary power source to anything that is sourcing power from the transformer.
    That being said your practice of installing that big round control power transformer is a very expensive way to go. It requires a lot of real estate inside that panel and large panels like yours are expensive. Another option for lower budgets is to buy an independent separate stepdown/stepup transformer from places like Vevor or ebay. They cost $70 vs $250 for a proper control power transformer. The typically come in their own case with a cooling fan which is easy to mount separate from the control panel. This can allow a person to buy a much smaller control panel and save at least $100.

    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

    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.

    NO and NC is the "de-energized" state of the relay/switch, i.e., the state it's in when it's disconnected from all power sources, and not necessarily the "resting state, the condition it is in all the time". I only think this clarification is needed because we use NO and NC relays at work, but we often have them wired to be constantly energized (so basically "NO, held closed" or "NC, held open"), so "the condition it is in all the time" wouldn't necessarily match up with what pins are actually connected.

    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.

    A properly applied crimp pin for instance in a connector shell beats a soldered wire to pin connection any time. Soldered connections are not common in panel building. Under some versions of electrical code, they are actually prohibited in some instances for instance in high current power carrying conductors.

    For the RJ45 option, you can do away with ALL those pieces except the cable. Get a tool to crimp your own cable and just learn the pin-out for each cable and input on the controller. Then you just put the individual twisted pair wires in the appropriate location on the male cable end and plug it into the controller. If you have 8 RJ45 connectors, buy 8 cables of different colors (get CAT6), one for each location, and get them at least 2x as long as you need, so you can cut them in 1/2 so you can make an extra or backup (or if you make a mistake). Allow for length needed to route cables. You can probably do away with 8 of those boards this way and about 200+ connections that could all be a point of failure.
    I've made 100's to 1000's of custom cables like this and they work well. If you ever need to run USB long distances, I found running over CAT5 works really well, you just double up the connectors, so it uses a single twisted pair (2 wires) as one USB cable, with will give you a total diameter/gauge 4-8x greater than USB cables - so there is less V drop and greater amperage capacity. I got it to run well over 75ft with standard USB2/3 over CAT5 cable w/ no "extenders" or powered aux devices.

    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. :)

    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.

    if you have a home depot near you you should buy spool of (rj45) cable and connectors wear the wires poke thru and when you crimp the connector it cuts off the what is not needed and leaves a nice clean look and yes they work great I did my whole home that way I hope this helps you save time and money and most of all room from having to much wire laying around and to many unneeded connectors

    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. :-)

    7:47 Jeremy, IMHO the simplest solution for your "translator" issue would be to make your own RJ45 cables. This is simple to do with an inexpensive crimping tool. This is done in crossover cables. You would simply rearrange the wires on the end of one of the connections. BTW great video.

    Maybe the wire you needed off the shelf was a "crossover" Ethernet cable? There are really just two types of RJ45 cables (crossover and straight through), unless the company who manufactured the encoder did something really special just for their stuff (a possibility). Your pin out board is a better flexible solution to make any off the shelf cord work as long as you know the pin out it needs to be. Probably save yourself money than buying "special made" cords from any manufacturer.

    Like a crossover cable? Where the wires are crossed so the order of wires is different at one plug than the other. They have them, but I don’t know if the order is right. You can cut the end off, reorder the cables and crimp on a new connector.

    Why use the RJ45 Switch board? You can cut one end of the cable and wire a new RJ45 connector onto the end in your new configuration. They also make a much smaller RJ45 breakout. Why use these at all? What was the problem of just cutting the end off and stripping back the jacket the amount needed and wire in directly? Just seems like extra expense and no one would have been the wiser.

      To be correctly pedantic, the connector is a an 8P8C modular plug. RJ45 is actually a telecommunications standard that designates a connector that is very similar to (but not exactly the same as) an 8P8C modular plug, and also a particular wiring configuration (a single telephone line wired to the middle two pins and a sense resistor across another pair of pins.
