This channel is dedicated to personal automation control through Computer Numerically Controlled motion control systems. If you're interested in learning about CNC I invite you to stop by, and have a look. The information here will hopefully save you time, and money. I strive to bring videos that are original, and thorough to help you on understanding motion control in all facets. Please visit my Ebay store under eDealers Direct for Gecko motion control systems, and CNC components. I offer personal consulting, on everything from business models, to machine fabrication.
Thank you for your support. Tinned leads are fine to use with terminal blocks, but like with ferrules torque of the screws on your terminal blocks should be tight enough to make contact, but certainly not over torqued. I suggest referring to your terminal block torque ratings, and purchasing a torque screwdriver. Thank you, Vince
could you see the installation of ground rod and give us your opinion under this name Grounding System Design and Installation -7 Steps #groundingsystem thanks
I think the arduino stuff is more name recognition and ease of use for very simple applications rather than cost. People will likely find stuff about how easy arduinos are to program before they find info about how it isnt good for industrial applications. In terms of other single board computers (Raspberry pi and its derivatives) and system on modules (single board computers lacking ports), $23 should get you well into the 1GHz/1-2GB Ram range rather than the 16MHz and <1MB ram from the arduino. Obviously this stuff isnt industrial equipment, but its at least somewhat modern hardware, and could probably handle RTOS stuff.
Thank you for your support. You may be right for certain cases, but I know dealing with many end users programming isn't for many people. Cost can never be underestimated when people make buying choices on components. Thank you, Vince
Hi Vince another gem to add to the list of education you give to us, so thankyou. I have a general question, is it ok to buy 7 core double shielded cable when only needing 6? Can the extra one be ran with the shield drain? If not, does an extra wire not used cause problems? I know you run the extra pin on the aviation connectors just thought id ask about cable. Cheers again mate! All the way from Australia.
@@petermcauley4486 Hey Peter, thank you for your support. Using a cable with extra leads is fine to do pending the cable is prepped properly not having the extra lead exposed when not in use. Typically what we see is end users simply cut them flush with the cables casing, and in best practice a piece of adhesive backed heat shrink should be used to finish the cables end providing a sealed cable/lead. If you require the extra lead to be run with the shield drain that would be fine as well. Thank you, Vince
i am from indonesia, i watched almost all your videos about assembling cnc controller, and after i watched your videos i realized what i have been doing all this time is totaly trash, its like perfect way to build a bomb. of course i am not a technician but i am grateful to have found this channel. i hope you can visit cnc build in indonesia channel, you will be surprised. (sorry about my bad english,its google translate)
@@corvetteguy50 sorry, i may have been vague. i would typically (i'm not an electrician) return my grounds to a steel bonding surface fixed to the chassis. then from there return to the ground pin on the IEC. (bear in mind 3d printers are as far as my experience extends). im just wondering perhaps said CNC seller done it that way. thanks
All grounds in best practice are to be run to a ground bus bar allocated to your electronics enclosure as you discussed. The power supply you're using for your system if built correctly would be grounded, and using a metal enclosure which would make it conductive allowing it to conduct to your metal electronics enclosure to ground it. Thank you, Vince
three phase motors run in reverse if the pairing changes isn't it, it just takes two wires to change though.. on spindles which support reverse (counter clockwise) one may need to be careful
Thank you for your support. You're correct. The other option to reverse the direction of the spindle is to press REV on the digital display of the VFD. Thank you, Vince
Wire coloring for the A/C side would be suited to your states electrical codes. These should be available through a Google search for your state. Thank you, Vince
Thanks Vince, I listen to your vids whilst I weld all day. And watch most when i need a visual, Ive relistened to all your vids series on mistakes content creators make, over twice now. 26 odd vids twice and some even 3 times to collect your input and info. So thankyou, Im retrofitting a plasma machine I bought new that ran a usb grbl setup but now i have all the centroid acorn gear {ethernet} Im in australia so its cost me a bit plus with your help, my machine will end up bullitproof. so thanks again, I have a question. I have many stainless steel electrical enclosures of various sizes. Is it a good idea to run the power supplies I have 3 {yes I know but i need that many} in a seperate enclosure added to the side? to isolate them further to help. plus all the shield drains and ferrites etc. I have the enclosures so thought it might help? and run the low output wires through glands into the main cabinet or 5 pin aviation plugs?. Any help would be great thanks. I get a few laughs too. cheers from Australia Pete
Hey Pete, Thank you for your support, and kind words from down under! You can mount all the power supplies in the same enclosure as the other controller electronics if you utilize ferrites, and double shielded cable as when installed properly the Acorn, and drives will be properly protected from excess EMI. Thank you, Vince
Hello. I have a similar cable - the wires are blue, brown, yellow-green, and please so the shield wire is soldered together with the yellow-green wire and connect to ground of wfd?
Thank you for your support. The answer depends on the robots requirements you're working with..?? There simply to many variables without knowing the expectations of the end user, and the machine you're working with to answer. Thank you, Vince
Thanks so much for the video. Would this apply to setting up the VFD for a wood turning lathe, .75Kw 415V 3 phase motor with 240V single phase power supply, lathe spindle speeds from 350 rpm to 3500rpm. Cheers
Thank you for your support. The settings provided in this video are for HY VFD's. If yours is a different brand then you'll have to review its users manual, and or contact its vendor for the correct settings. Thank you, Vince
With reference to your first observation. In the UK 240V mains power is provided by the Line and Neutral, where Neutral is actually tied to earth. Therefore the vendor is correct.
Thank you for your support, but the video was intended for US audiences as that's where it originated. I want you to review what you just typed above carefully, and I quote "In the UK 240V mains power is provided by the Line and Neutral" this would mean both of these lines are providing each VFD R, or S terminals based on this video 120v. This is the only way to power a 220v rated VFD as I discussed in the video which is accurate. Thank you, Vince
In the UK, with respect to earth (ground) the Neutral is at 0V and the Line is at 240V above earth. Therefore between Neutral and Line there would be 240V A.C. As you know, in a VFD the AC mains supply is rectified into DC which is then used to drive a three phase variable frequency oscillator to provide the output. Apologies if you have already covered this.
Incredible job laying this out. I consider myself expert level and the way you did this was too easy to follow...I mean that as a compliment. Thank you.
Safety is so vanilla. I suppose it depends on who you are getting the "educational information" from. If it's coming from the government, believe every word. Another great, informative video, Vince. Yet again, the things you think are common sense, are not so common anymore. We need to get fathers back in the household.
12:30 or it is people who religiously pre-tin (which usually means you will do fine with what is in the flux core, at the cost of much more wasted solder wire - so probably fine, albeit inefficient).
9:46 connectors like these are even more tricky in regions where unleaded solder is the standard. Haven't handled this exact connector before, my approach would be to a) use a good quality SN100Ni+ solder and b) mount a mating connector in a bench vise, mount the connector to be soldered to the mating connector, only then solder - and very thoroughly inspect it afterwards. This setup will reduce connector warping due to soldering heat a lot, but it can also hide further heat damage (eg seized pins that are supposed to have play).
7:40 I would personally want to use longer and if possible double heatshrink on soldered connections - at the length shown there, somebody inexperienced or just not paying attention could easily end up with solder wicking up beyond the heatshrinked section, making for non optimal robustness in a vibration prone environment.
4:40 the question "will this be safe with 220/240V" is more complicated even. Is it rated? NO, period. Are these maligned US plugs safe at all even at 120V , given how they can expose conductors while being plugged into a flush socket? Errrr, NO. Would it be any better at 240V? NO. Will the insulation handle nominal 230V or even 400V? most likely YES (so will telephone wire, should you use it on 230V - most certainly NOT). Would it meet the specifications for possible transient voltages on a 230V mains? Likely yes, but unless it is rated or you MEASURED it with a hipot tester, there is NO telling (insulation for 230V mains needs a surge rating north of 3000 volts (!!) by most standards, and for good reasons). Also mind that new parts can meet specs that parts that had the expected amount of wear and tear no longer will. Are inverter-ish devices, and a VFD is such a device, always safe running at half the input voltage (as could easily happen when you put a 120V plug on it!) - surprisingly NO, if they are not designed for that, damage to the device is possible (in the worst case, overheating it) - someone asking "what clown put a 120V plug on that if it isn't supposed to go into a 120V socket?!" if something happened would be very justified.
I think what the top forum post at 3:14 actually refers to is a condition that can happen in three phase building installations in the style common here in Europe, which have a 400V 3 phase lead in to the building and break this up into 230V circuits to supply wall sockets, in a wye configuration. A bad neutral connection can get the neutral point in that wye floating and dependent on how the other circuits are loaded - which can end up supplying 400V to wall sockets.
Reading nominal 220V on reasonably modern looking equipment seems odd, given there aren't that many places left that haven't gone 230V/240V nominal, and 230V/240V equipment can be designed to accept 220V nominal voltage tolerances...
Hello there. I really enjoy your videos, they are very definitive and straight to the point. thanks so much! QUESTION: 9:11 you are saying that the H17 connector is the hardest because it's so small for a proper 16 shielded spindle cable. WHAT ARE THE alternatives? I'm asking because I'm installing one next week. I totally agree with you that the metal housing is way too small for the upgraded proper premium shielded cable that I have ready to go. thanks in advance for any answer or advice on this.
Thank you for your support. Machining the connectors housing as shown, and discussed on my channel (search H17) shows what must be done to install the connector. There are no alternatives unless you swap out the connector, or spindle that utilizes it. Thank you, Vince
My lead time currently is 3 days with my current shop load. I need a length to provide a quote. Please email me from the video's description if you would like to move forward with the purchase. Thank you, Vince
Thanks Mr Vince for this free course. your channel need to spread in you tube a little note maybe you are using hard keyword to find you channel from new learners in this genre if you use like this Plasma-cutting and make a search your channel doesn't appear in the first you tube page
@@corvetteguy50 Maybe you will go the same path with VFDs as you did with the controller build or installed incorrectly. This video's keywords don't match the title, making it hard for new learners Guessing it. Mr. Vince, you bring new content, which is great. Use old keywords that RU-vid's algorithm knows it
In all my years, I have never taken anyone who chews their fingernails seriously. This kid needs mental help and to watch videos by Pros before he starts to make his own video.
LMAO. He disobeys his own disclaimer. Sounds like 'do as i say, not as I do.' Phony 'maker' videos need to be removed. RU-vid needs to step up their game.
Just starting to build some cnc equipment. Thank you for your teaching videos. If you get time a video on wire ends/ connectors would be awesome. Like the ones for the arduino pins. male and female connectors. and the proper names. Thank you so much.
Thank you for your support. Arduino boards shouldn't be used for CNC production robots as they are unstable. A Google search on this will reflect the many issues end users have. Thank you, Vince
@@corvetteguy50 thank you so much for the info on Arduino boards. We will look at picking a different board. we are building a cnc plasma cutter and a cnc router.
You should be using an ethernet board/controller as it will provide the most stable platform for your robot. I recommend my UC-400 turnkey package from my store if you're looking for a controller. Thank you, Vince
hi im about to convert a mill over to cnc and ran into something. maybe you can give me your input. i got some nema 34 stepper but the connections for them only come at 18/4 unshielded. i just built my plasma cutter with different motors i had to manually wire and made sure to use shielded cables i could ground with 5 pin connectors. i could remake these cables its just weird shielded wires arnt stock on them. how much would it matter if the first few feet coming off the motors arnt shielded?
Thank you for your support. There's now way to answer your question as its impossible for me to know the shop environment your installing the system in. I will tell you though a few feet is arbitrary, and in best practice using the proper double shielded cable provides end uses piece of mind if they're installed correctly. Thank you, Vince
My soft limit switches work but when jogging by hand with the arrow keys it will try to stop within an inch going at about 700ipm which makes my stepper motors skip position, I even set the slow zone to 3 inches 4 7 or 10 but still wants to stop within and inch and I lose steps.
Thank you for your support. unfortunately without seeing your system/settings its impossible to diagnose. If you want to setup a consultation just let me know. Thank you, Vince
Sure the gas strut may be there because the spindle otherwise would fall because of the added weight. But it actually comes with quite a lot of benefits to the load put on the z motor 2d operations making it stay at the same hight. And making a new controller from the getgo would just bring the price up when it isn’t really needed and they also mention that it is a very easy install while changing out electronics isn’t really for the inexperienced. If you do your research you can also find many industrial like Cnc mills using gas struts maybe more common is using a counterweight but using a gas strut is definitely not wrong. I just want to say I very much respect you and your videos and I have learned alot from them but I just want to bring to attention the gas strut actually is a quite cleaver idea, haha
Thank you for your support. I appreciate it. Unfortunately, we have two different opinions on the correct solution. Using a motor with an integrated brake is by far the most professional, and simple way to keep the spindle from falling. It also reduces parts count of the entire CNC system. The reason the vendor we're discussing didn't implement it is because as I said in the video its a quick fix to an already released version of their chassis. Thank you, Vince
Good morning Vince! I was driving to work, and I got the thought to ask you what the little tool you use to protect the wire insulation when soldering is called? Id look around if I had the time right now. Thank you. God Bless
Thank you for your support. I'm sorry I don't know what tool you're referring to? Do you mean the jig holding the spindle cable leads when I'm soldering on the spindle connector? God Bless You As Well! Vince
Mr. Vince, why you don't use db9 connector with VFD's client? I think the way you did it with your VFD hides and save the wires. Maybe you do it to meet what clients want and are willing to pay for.
This is correct, have a look here I'm ahead of you on your question for this client ...:) ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-t2FIT1E2PyA.html Keep in mind its best to search my channel as I have almost 500 videos which usually will have one covering a question. Thank you, Vince
