For mounting things on the panel - rivet nuts massively simplifies assembly, and allows components to be removed individually from the cabinet without having to remove the back panel. On that note - those back panels are made of mild steel - get yourself a switchable magnet and you can lift them out easily Also, for drilling holes for various connectors - check out step drill bits, they're great for being able to accommodate lots of sizes in sheet metal without a drawer full of tools, and they will chamfer themselves which makes cleanup easy

I was going to suggest the same. M6 self tapping torx on DIN-rails and M4/M5 for mounting circuit boards directly to the enclosure backplane. The power supplies for DIN-rails are quite compact, might be an option help you with layout size constraints. They are taller but looks like it would fit the enclosure used in the video. Nice job btw!

Great video! To answer your question about the best way to mount your equipment: I'd like to suggest using rivet nuts to attach your equipment to the sheet metal enclosure, you will find that they are a game changer. They are very cheap, easy, your nuts are permanently mounted exactly where you need them, no more fumbling around trying to hold the nut in the backside while you try to get the screw to line up, it won't come loose from vibration and short something out, and they will give the whole thing a really professional appearance.

you can use spring washers to prevent the units from coming loose.

Also 3d printing mounts makes it easy to mount the parts in your cabinets and it also keeps them seperate from arcing out on the metal cabinet and it helps hold the screws tight u can use heat set inserts and the plastic keeps the screw from just vibrating back out

I’d love to build a CNC mill. The electronics are the easy part for me at least. Trying to build a machine rigid and accurate enough seems like a tough task.

Yes, that is an excellent point. The ones I did here were sufficient but I will use those washers next time.

I would have used a CNC to do the panel holes and the labels can be engraved. Not only is it more clean but the holes will be perfect and you can check for alignment issues prior. Also the use of ferules would have made those single power and other wires easier to install. (Ferrule Crimping Tool Kit are easy to find and are not overly expensive)

Just responded to similar questions in a recent comment. Every cabinet is different. Customers have their own requirements for connectors, cabinet size, arrangement of components inside (i.e. VFD mounted in or out of the cabinet), etc. The cabinet isn't stiff or stable enough to machine unless I created a jig, but that would be difficult with the type of machines I build. That would be more suited for a vertical mill. I am changing over to punch and die which is far easier and faster. If I was making the same cabinet over and over, a jig and CNC would be a good choice.

Yes, the terminal used for the smaller wire needs a ferrule connector to enlarge the surface for the screw to contact.

@@SodiumEx Not necessarily. I listen and learn from commenters like yourself, which is why I don't use the ferrules and follow the NEC. Having loose wires will, of course, depend largely on who is installing the wires into terminals. Terminals are designed to accept bare wires. The argument against the use of ferrules is similar to the argument to use them, it depends on the person and tools used. If the ferrule is too big, then the ferrule will not be effective and thuls can cause potential harm to the devices or the equipment overall. Using the correct size of ferrule is best, but one cannot determine whether a ferrule is properly installed in a field of installed ferrules; therefore, the use of ferrules cannot be trusted as a whole. When I use wire ferrules, I use them in circumstances where I feel they will be a better fit for the connection.

Do you save money doing it this way? I remember at some point in time building your own computer became more expensive than getting an already made one as an analogy.

I have an Avid CNC and I bought their CRP800 controller. When you look the components inside and add up the cost, it’s between 50% and 60% of what they charge for the plug and play unit. So if you don’t value your time and you already have the tools to build the enclosure and the cables, yes you can save some money but not much IMO. Personally I don’t regret buying the controller pre-built because you see that they are using DIN rails to mount the drives and the power supplies. All the high voltage sections are routed away from the low voltage logic section. Just to see how true industrial grade controllers are assembled was a good learning experience for me. So even if I already had experience doing all the wiring of a hobby grade CNC I don’t regret buying a pre-built controller.

Now I use an enclosure one size up from the first that theoretically would house all desired components. I guess I was born with fat fingers. Sigh.......

@PatrickHoodDaniel I didn't mean to be short, I didn't have a lot of time to explain. I build panels and controls all the time for our business. Not cnc, but industrial automation. A punch is nice and clean, and you were right for stating it would have been better. Mag drill is definitely not the way to for this type of work. As you found out, they don't work well with thin base metal because there is nothing for the magnetic field to generate. The thicker the surface, the better the grip. We use 1" steel work benches with our mag drills. That being said, we hand drill much of our panels. We sometimes use step bits in the process. We occasionally use hole saws if necessary, and our favorite multi-hole solution is our water jet.

Ugh... where to begin. @4min you say you could add shielding. I assume you are talking about adding plates in the box? Any 'gap' or arrangement you mention is nothing. You would need several feet to mitigate EMI interference, not inches. All cables, and I mean ALL cables, should be shielded with the drain to a common ground. You talk about the shielding bolt being grounded to the case. How? There is paint everywhere. If you are adding a wire from the cover to the case then you are making several ground loops, which is not good practice. You use normal wire from VFD to spindle??? That is where most of your EMI will come from!(Have I mentioned shielded cables yet?) Then all the horrible crimp connectors... my god, man. SOLDER+ShrinkWrap! Lastly, Vevor is not making industrial anything. It is 'pro-sumer' stuff.

I’m going to be wiring up my second cnc control cabinet and I’m deciding on whether to use shielded cables as extensively as I did on my first build for a cnc plasma table (the current build is for my cnc mill). I notice most people don’t use shielded cables/wires between the steppers and controller. This saves money and effort and it obviously works. The question is does this allow occasional errors. Even Centroid says nothing about shielding outside of the Ethernet cable that connects the pc to the controller. It should be noted that the op is wrong about proximity. Depending on the source a few millimeters is enough space to mostly mitigate the effects of EMI. For example a few millimeters is enough space between signal wires and a plasma torch lead to have perfect operation. Likewise about 3 to 4 inches from a switching power supply is enough to protect against EMI. I do agree with the op that I don’t see any evidence of proper cable shielding being used in this video. It’s not enough to have shielding, it also has to have a drain to ground on only one end.

@@anthonydomanico8274 It is perfectly fine not to shield, but wire/cable placement is important to limit crosstalk. You will want to test the signal with an oscilloscope to confirm the signal is clean. There is a no-mans-zone in a signal that the controller will not know if the level is high or low. Probing the signal will allow you to see where this signal lands within the constraints of the signal (i.e. 0 to 5v). Follow wire/cable routing standards like don't run signal lines close or in parallel to high voltage/current lines.
