common fact that the guidelines to wire up any of the components in motion control are missing out on a lot of information, thank you for adding in the blanks
I assume you reached out directly to the author of the referenced video and/or the vendor to provide some productive guidance. Everyone deserves support to improve. I appreciated the information you provided in this video.
'The content creator of this video was actually mad that I didn't "plug" his video as he was more concerned about getting more views on it then actually reflecting on what the video was showing his audience.
Very real. You buy it, you wire it as they showed, you fry something. They claim it's against their warranty and they don't warranty the driver you are hooking it up to. But also, don't think that most manufacturers are any better. I've bought the same brand of inductive sensors that a bunch of machines use at work. And their wiring diagrams were so unclear, we couldn't tell which side was power and which was the output signal nor if they shared a ground.
I’ve never owned a CNC before and I installed a MASSO on a Gerber 4x8 table saw. It was a little complicated but it’s doable. I love it! It’s been running for over 2 years in my sign shop mostly cutting aluminum and acrylic. I bought the CNC on Craigslist for 1k Very happy with it. Just my opinion.
Thanks Vince for the instruction. I also have a Masso Touch for my PrintNC build. Still trying to get as much correct information as I can. I will not even try to wire and power up until I am confident that i understand what I am doing. Thanks again.
Thank you for the Info. Onefinity is using these for their controllers on their elite series machines. I own one of these machines and it only recently arrived. I posted a video the other day that shows how I wired up a wireless MPG to the masso for testing. I totally use the wrong wire and not the best practices when hooking it up, I plan to fix those issues so please don't roast me :) The reason I mention it is in my video I open the controller and you can see how they wired it from the factory, not a single shielded wire on the entire build. With my multimeter I wasn't even able to find a PE connection anywhere on the machine itself of the masso unit. Nothing is grounded at all, no where to bond the shielded wire to if they had used it anyway. The power unit box is the only thing grounded and its a few feet away. It actually surprised me when I first opened it. I have plans to do something about it but who knows when I will have time to get around to it. They sell a lot of these units to people who don't know any better but I'm sure the other "hobbyist" machines are the same.
Thank you for your support. I heard your table noise issues, and I only do videos on end users trying to make content about controller builds if they are done incorrectly. I'm glad you solved the issue as I saw the follow up video as well. I would love with your permission to discuss what OneFinity wrote to you as I saw it on their forum. It's a vendor's obligation selling these robots to be held accountable to after sale support. I hope you, and your family have a Happy Thanksgiving! Vince
Probably the reason he didn't ground the board is a quick read of the masso g3 pages warns about grounding it to the machine and states that the board is grounded to the mounting plate, so mounting has a potential to create a ground loop. So he's simply following the warnings masso gives...
Thank you for pointing out the grounding problem. I think you just saved my project just in time as I am in the final stage of rounding up components to retro fit a Multicam M1 router ( re badged AXYZ Millennium router ). I was planning to swap out the old control board with a Masso M3 controller, using as much of the existing wiring as I can. now the existing spindle is a single phase 240v that goes into a 3 phase 240v inverter to drive the spindle. I already have a new spindle and was planning to replace this, it is a new 240v single phase spindle that is driven by a VFD, but this is to big to fit the current controller space, so I was planning to house this and all the transformers in a separate control cabinet to remove as much heat from the current controller space. The question is now , how do I ground this properly to avoid a ground loop, do I run a ground wire from the cabinets ground to the controllers ground bolt, where all the other grounds are attached, as I would have to ground it in the cabinet that it is housed in. so how would you properly ground items in two separated locations. I would appreciate your advice, thank you Peter
Genuine question, I was always told to think of cable shielding as a faraday cage for the conductors. In the video he doesn’t terminate the shield, and you mention he should ground the shield. Since he is just passing the cables through a hole in the enclosure, even if they were grounded wouldn’t EMI still make its way into the enclosure through the gaps? I thought that’s why gx connectors where metal, so that you connect the shield to the metal connector, which wraps around the cable and makes contact 360 degrees around the cable ensuring the cable and enclosure don’t have gaps for EMI to get in? I’m probably wrong, I’m not an electrical engineer.
Thank you for your support. EMI is always present, and you're correct that EMI can penetrate any gaps in his metal enclosure as well. the big question is how much? Well without an EMF reader you really don't know if the level would affect the drives, and other components as each have different levels of tolerance to it. If you use shielded cable and believe you don't have to shield the cable drains then you're turning these cables essentially to standard unshielded ones, or worse allowing them to not dissipate the electrical noise which can also lead to signal penetration, and their corruption. The GX-16 connector option works great, and you're correct for attaching the shield drains these allow the fastest termination and leak free noise protection. Most won't use them as they take time to solder, (multiply each terminal required for use on these connectors by how many leads building a system have, and all of a sudden, a controller price of 3-4k makes sense) and truth be told most content on UA-cam reflecting soldering with CNC controllers is never done correctly with flux which is why the joints for most end users look, so horrible. The bottom line is more UA-cam content on CNC controllers is just that "content", and you never hear most of these people explain that the system is built for them, and the skills in the video represented shouldn't be used by other's because they explain they have no idea if what they're doing is correct. They project they are knowledgeable about the subject making their audience believe they can help them. You can see this in their comment section. This is really scary considering another analogy of this same situation would be for a person never claiming to be a surgeon, but uploaded a video of them performing surgery on themselves leaving others to believe what they're seeing can be a "simple DIY project". Ultimately, they project success at the end of the video depending on how long it takes for any complications from an infection setting in, or dying but to their viewing audience at the end of the video they appear fine that is until of course they aren't. This is where UA-camrs need to proceed with extreme caution with their content, and stick with topics they understand, and should be held accountable for spreading incorrect information to the masses. Thank you, Vince
Onefinity is now using these, I wonder if it has been grounded properly or not. Haven’t heard of any issues yet. Not knocking Onefinity, I think they are great machines for what they are at a price point.
Thank you for your support. Remember a robot must be looked at as a whole machine, and not as separate units in that if the chassis of the robot is built correctly, and the controller isn't then the system as a whole is a failure as one controls the other. This is the big problem with the understanding of production robots we see on UA-cam all the time in the content discussed. It's a good question though, and one that should be asked to the manufacturer, and if they can't answer it then that is in fact the answer. Thank you, Vince
I wish someone could figure out how to bring an affordable ATC to the market. I know this is very hard, but whoever cracks this will be the top dog. I hope Vince is working on this quietly.
Great video: I’ve seen bad grounding cause all manner of gremlins and problems. The issue is that there is not really a cohesive doctrinal define design, guidance or methodology on grounding. If you ask a half dozen electrical engineers, you will almost invariably get almost a half dozen opinions on how to ground system. One thing I always do on any data lines is make them twisted pair (usually 50 ohm). This will at least cancel out differential mode noise. It would have been good to include a tutorial on this in this video (or a next ;-) on how to do it correctly.
Thank you for your support. Twisted leads isn't as effective as passive filtration (EMI ferrites) and takes much longer to do then to snap them in place. Price isn't an issue either as they're really reasonable. These are in best practice to be used with CNC controllers as they guarantee stability when properly used. Thank you, Vince
Do you reach out to the people who's videos you critique to offer them help and guidance? It's apparent that lot's of us have no where near your knowledge and experience with cnc machines and we use UA-cam as a way to learn new skills but if we learn incorrectly it can be at best frustrating and at worst dangerous. I think it would be a huge help to the community if you not only pointed out all the issues with these videos but at least tried to educate the video creators so they can possibly correct their mistakes and by doing so save people down the road in the future from making the same mistakes.
Interesting analogy, but let's tell the truth about what you described. Its apparent these people posting their controllers that are in my CNC fail videos really don't care about doing anything right, as much as they care about posting content for their channel. Why do I say that? Because these same people generate a profit from having their videos reviewed by people they don't care about, or they would simply do the proper research before posting it to be viewed publicly as common logic reflects it may negatively effect the audience they claim to care so much if what they were posting is incorrect right? I offer consultations for anyone wanting to invest the proper money in themselves to learn the correct process to build their controllers as this my career as an EE designing motion controllers. I'll certainly go the extra mile as my subs, and feedback represent that. I already supplied the community over 400 videos on my UA-cam channel for free, which is well over a college course, and if someone does a Google search, they're certainly going to find my videos. Not one other person in my field has done anywhere close to that. Please verify it. If novice's attempt to put the time in to view the videos carefully they'll learn, but if anyone expects to be mentored on this, or any other topic then this is what's called "billable time" as it would be for your career. The truth is most of these end users want to use forums as its free, and they simply don't want to pay to get the correct information. They also don't spend the amount of time required to learn it through reviewing my videos. It's really interesting I notice in this field of interest free verified knowledge tutoring seems to be expected, but if it's another career field say for instance you need a mechanic to fix your car that knowledge is considered valuable, and paying him to fix you car is required, or you're walking. The same can be said about going to school, or college to learn something. If its a field you want to learn then your pocket better have the money to support it. people justify education all the time. The clients I work with value me as they realize my knowledge will make them money if they can run their business with these robotics. These are the people that understand the value of what they receive when hiring me. Novice, or experts they realize they want a professional to achieve professional results because they are professional. Thank you, Vince
My opinion, they said enough. But this view is based on someone having the knowledge to do the wiring would have the knowledge to understand ground loops. I am not referring to a diy guy having ability to do wiring, but understanding wiring. All that being said, if a person is not familiar with the instruction or needs further assistance, they should stop and get those answers. Now is it the duty of MASO, my opinion no, because there is an expected level of knowledge that the user is believed to have.
Thank you for your support, and comment. I'm going to tell you the simple truth as I realize you bought the unit, so you're a fan of it. No vendor should be selling CNC hardware without providing all the proper required wiring diagrams, and all required documentation to enable their end users regardless of their knowledge levels to achieve a fully functional system. Here's another video I just made on them claiming they provided the required information for connecting an HY VFD, when it fact its missing the correct information once again for their clients. ua-cam.com/video/d1dXCFDX33U/v-deo.html You do realize they're marketing to the DIY crowd as that's their gimmick. Show me on their site where it says their hardware is designed only for professional installation. Its obvious that all the diagrams they provided are generic at best, and don't follow "best practices" by any drive manufactures, and other components. Their troubleshooting section on their website is comical to say the least. One more quick point, and really I want you to think about what I'm typing here, as I'm respectfully telling you talk is cheap especially on the internet. Claiming you have the knowledge of correct wiring practices, and understand ground loops, without having shown any social proof of that on your channel by showing your system before making such claims makes no logical sense as no one on the internet has any actual proof of your self proclaimed knowledge. I recommend before making any claims based on your CNC electronics knowledge that you make a video of your system as many people online project what they believe is "correct" as you can see by my fail videos covering these UA-cam content creators only to be shown direct from component users manuals they're wrong. Thank you, Vince
Thank you for your service in the Navy. An ethernet controller that's non proprietary. I prefer a UC-400, as its the most economical, and allows use of Mach3, and UCCNC motion control software. Thank you, Vince
Their primary advertising/target customer seems to be home shop machinists, not production shops. And even selling to professionals, having any customer wire something and fry it (even though it's the customers fault) is bad marketing. Even a cheap amazon special flashlight comes with instructions on which way to put the battery in. *When a simple 1 page sketch and 2-3 lines of text stops a customer from frying brand new equipment and countless troubleshooting sessions, it's stupid they didn't take 5min to draw it up and tell marketing to include it prominently.*
I'm sure this guy is technically correct but it's hard to take someone seriously who's criticizing a successful UA-camr for not doing things correctly when he can't even get his audio correct. I first thought you were using a $3 microphone from 20 years ago but you somehow screwed up the recording of the other youtuber's voice too. The bottom line is: if it works, it's not stupid. And his machine works. The parts he makes are accurate. I work at a steel mill that doesn't follow any of these best practices. Our electronics are subjected to the absolute worst possible conditions, extreme temperature swings, right next to high powered drives powering massive motors (there's even some unshielded signaling wires run right along side the power leads for those motors), not properly grounded (sometimes not grounded at all) and they all work just fine.
No different than its hard to take a guy seriously who leaves a UA-cam comment claiming I'm technically correct to insult someone trying to help his audience by showing proof of best practice. You do realize your essentially saying because I'm not a UA-camr who's a professional movie maker/entertainer using high end recording equipment, and the company you work for isn't using best practices when it comes to a properly built CNC controller designed to mitigate EMI which can corrupt the control signals of the production robot then no one needs to worry about it?? I think what you're really upset with is you're a fanboy of the UA-camr the video was made about, and it upset you someone did a video on him exposing the truth.
