Tony - your comedic timing, writing, editing skills, and expertise as a maker are all things I aspire to achieve even a small fraction of one day. Hats off to my all-time favorite youtube creator, I'm sure you've no idea how many people you have inspired.
Damn lol I learned more than I ever thought I would on this topic hats off to you as well 👍
That was a great video.
Every time you say Linux CNC Physicsanonymous shivers
Oh cool, I work for SKF. Great video!
is there a ball caught in the white plastic on top of the screw around 5:41 ? sounded like there were not enough balls inside or too much space in between, same as the bicycle I inherited in 1985 and which had extremely worn balls in the ball bearings
I'm a complete novice and most of what you say is above my pay grade. But you have an addictive way of explaining things that compels me to watch every video you release multiple times. So well done TOT you steal a lot of my IRworld surfing time but wouldn't have it any other way. Keep doing whatever you are doing (don't fully understand it but it looks and sounds impressive) And I look forward to the next video, whatever the subject matter is.
Awesome stuff Tony! 😃👍🏻👊🏻..... "Coincidentally" wearing my TOT hoodie and t-shirt while watching! ✏️❤️👕
I really enjoyed this video, thanks
Million subscribers yet?
Was that an electric chair joke in the beginning there Tony.
This was a good video Toe no doubt....cool huh... If I ever find the money and time to acquire a decent monarch 10EE I'm going to approach it like a refurbishment because it's a metal machining tool.... buying one new requires super careful preparation can you imagine purchasing a used one that you have no knowledge of its usage in the past or the users knowledge of the neccessary upkeep and calibration standards.... that block set ol' Toe here brakes out to qualify his milling early on by itself is definitely a must have and $1100 used and sorry but u don't buy "used" calibration equipment. U can i guess but it will not be standardized so, then you will have to send it out for calibration which will cost more money. I can tell my boy here knows this. Yeah, I'm eager to start doing that 10EE. Getting one and getting it functioning and looking better than I could have imagined would be so exhilarating for me because I haven't ever met another human being that is a good person so I have to do shit myself because if i left it up to the scum bag mf i have to share my world with they would lead me to believe i wasn't capable and they want me to send my children around them and destroy them too. My oldest daughter was tricked and they murdered my first son but, i promise they won't take my son and baby girl People don't change you are right it's just me man just me I'm the only one who changes
As good as you are with this stuff, it's harder than stopping biting your nails. Paint em with flat clear it worker for me.
Tony if you want to ballbar your machine to see the accuracy with a Renishaw let me know.
Just discovered this channel (as in Mar, 2021). Eating up the content like warm beer nuts. Really has me questioning my life's choices.
So much words??. No subscrib
Dont takk just make.we undrstand
is your Y axes issues from the shaft "buckling" in the one direction. It would account for why it is one direction and not the other. Is the head pretty tight in the dovetails?
Hey Tony, I'm an employee of IntervalZero. It was great to see someone use our product for personal use! Our product is so far down in the chain of production I rarely ever get to see anything physical come of it!
5:24 the crunch sound is from the white plastic pipe rubbing on the metal hose in the background, if you mean this sound, I dont hear anything else
@This Old Tony, is it me (or maybe an optical illusion) or does your y-screw look like its not parallel to the ways @5:30 into the video?
how much is the the oval ball field in metrics. Because there is no point of translating freedom units to metrics, if you don't explain the distance of your hand egg field size.
That's not bad Tony. When I say that's not bad, I mean it.
Love the 3 axis MPG. almost certainly going to make one for myself.
Your freaking cut-away visuals are the best freaking part of these videos. The subtlety and humor is fantastic.
Well if my lathe breaks down I know who to call. Lemme know if you have a transmission go out in your truck.
your Y nut is missing balls
When Tony first started this project (and I know nothing about any of this) I thought, “Oh cool”. And then, months later, I was like, “whatever happened to that Maho project?” Holy moly, now I see why. Way more complicated than it looks. What a project.
Pure overindulgance in precision cutting makes me high. So i must buy a mill, my Lord.
Oh boy!!!! TOYS!!!!!
I love the subtle dad jokes!
so what was causing the bearing noise? did not see you fix it.
"Feel free to skip if you want" OF COURSE I will skip several times. But BACKWARDS. There are some jokes so good I love listening to them several times. 😂😂😂😂😂😂😂 BEST. CHANNEL. EVER. ❤️❤️❤️
I have an idea for the problem you are running with the Y axis. The ball thread has one slide to the side of it (the whole slide of the head), causing it to bend in one direction thus being super unhealthy for these bearings. How about putting an extra bearing in a strong housing that is set to take on these forces? Or better yet give it a 'second slide' that Will counter the pull from the Main y axis slide.
The Maho green is called machinery green in Germany and the color code is RAL6011 not RAWR! ;-)
Those of us who have never been to a football field can't imagine it
Ok........great video......as usual!!! Ok......and i m not to smart..........b u t.......WHAT THE HECK DOES ......MAHO.....stand for..??????
I didn't even realise it was a 48 minute video lol watched from start to finish and enjoyed every bit.
Tony, do you know what max RPM you have seen from these servos? Do you ever get close to the 3000rpm limit for the ones you have?
❤️ from India 🇮🇳
Servos to the ribcage help with safety. Dangerous workspaces need bruising agents to remind you to watch yourself.
Please do a gas spring video that would be amazing.
I still fondly remember the FANUC servo-tuning "blip" sound from my days working on CNC machines. Also, I now happily spend my days no longer working on CNC machines.
Does she still speak with a German accent?
Super Awesomeness again, as Always!!
I'd buy the Maho OnlyFans
!
Might want to add some movement locking switches or some sort of "dead-man" type switch to the MPG cube. I'm sure it's mostly fine, but I'd be worried if any freak vibrations on the table causing an MPG to move when it shouldn't. Or worse; something goes wrong and the cube is knocked off of the table, it hits the floor, the mpgs spin and send all the axes in random directions, your work is ruined, your tool explodes, the spindle is slammed into your vice and bends, and worse; you have to bring your router back while you spend a few months fixing the Maho.
The difference in surface finish is most likley because one of the sides is climb milling (nice side) and The other side is conventional milling. I suspect it wont go away compleatly, unfortuneatly.
Industrial electrician sees this and is beyond extremely impressed. Same guy looks at that panel and is utterly horrified! Get it sorted out man! Great channel definitely subscribing, just promise never to show me in there again!
19:00 So are you going to add haptic feedback for the machine loads? Then it would really feel like manual jogging...
Tram (apparently) is the parallelism within the x-axis. But NOD is the parallelism within the y-axis.
From start to finish, how long did it take to make this video?
That ballnut replacement @5:18... Is it me or the crunchy sound also matches up with the metal wire harness grinding against the plastic tube rings... There is also a solid ground groove from the contact grind in the plastic tube...
I would never think to skip around on your videos.
Man the strange ticking you were hearing at the start of the video were the two pipes sliding one over the other, around 5:25, look right
Very, VERY informative! Thanks TOT for having taken what is surely a TON of time to put this all together.
Tony, you had me chuckling all through this. Keep up the humor, it makes learning about machining so enjoyable. Cheers!
I think that the crunching noise on the Y axis ball screw nut is caused by a misalignment, it makes that sound only when the bearing block is going towards the machine, that causes to bend even more and to destroy the ball screw nut
You’ve gotta be careful when working with dehydrated steel. A mate of mine didn’t have his coolant mix right and the piece expanded by 20x, he hasn’t been the same since
That machine sounds as bad as I feel
Why a Mach based controller and not a commercial controller and software?
"...but it can become a rabbit hole if you keep thinkin' you could just get a little bit better." Truer words never spoken!
11:35 had me in a fit of laughter hahahaha
Scratch that the whole lot did hahaha
This Old Tony relly blows my mind! Where are you based out of?
Just a heads up I was a machine builder for American Broach and built alot fof the CNC Broach Sharpeners and I might have some insight for your ball screw problems too. We need to Colab !!
Tony, I have been enjoying your various machine projects. And do a nice job explaining/how-do. This might be the first time I popped 😳 a comment. If you're interested, for some good add on's to automate, for your machinery. Have you ever heard of Direct Automation 🤔. Check out this company. One day, we should chat together.
What did i just watch I'm sure it was some guy talking about a big green machine that does some sort of wizardry with metal
I love me some long format Tony.
Don't worry Tony. I watched the whole video. I even rewatched some of it because i kept getting distracted.
Hiya
Don't worry about dove tail ways unless you have to hold .001 tolerances I operated a nc bridge port in the 70s with dove tail ways. no big deal Since then I operated and maintained 14 different cnc's . 13 had box ways, and I could hold .00005 tolerance on grade 2 titanium on a Takasawa lathe . We had Mazak mills and Lathes and Yams too.The only machine with ball ways was a Swedish drill press with 54 x 72 in travel. Are you Canadian because you work in metric? I still have not changed over. The ball screw clicking could be that you do not have double ball nuts face to face preloaded apart. This eliminates any backlash and some ball nuts takes one directional load only. The ball screws were anchored at each end with double angle contact bearings . to keep the screw from flexing. We would take 2in thick 304l stainless plate clamp it on two inche copper parallels so it would not slip also to allow for the chips to clear the cut.Chips and heat are your enemy! Drill a 1in hole thru the plate and use a 1 dia x 2.25 in corncob end mill all the way thru the plate . 200 rpm and 2in of feed full depth to make this plate into a doughnut shape. Did this for 39 years. Corn cob cutters are the best,1st rule of milling always climb cut, 2nd rule of milling always climb cut, 3rd rule of milling never conventional cut Use double ball nuts face to face preloaded and double angle contact bearings at both ends of lead screw. Have a good day.
Where did you get those gas shocks? Need a pair for my 100 year old mill. The table weighs around 500 lbs at least. Needs help going up. Have to buy a 2hp motor just to move it. Got a car steering wheel on it now. The base the table rides on is huge. The table 32inch and can move 38 inch left or right because of the huge base it's on. And no the ways aren't over tightened.
connector is a dbhd44. better than a db13w3 i guess.
The cause of the .0001 drop is what is causing your Y axis to chew up.
Hey Tony, what camera or cameras do you use to record your videos?
Hey Tony, it almost looks like the y-axis crunch sound is being caused by those two hoses rubbing together! Just a thought!
Good job you can make an Chuck
Hi Old Tony, when you cutting a cycle cw the mill behaves like conversational milling because the left side cuts more material, and when cut a cycle ccw the mill is behave like climb milling because the right side cuts more material, I thing this is the reason you see different finish in the s type groove
@ThisOldTony I'm not sure if you were joking, but at 5:23 you can see there is a tube rubbing against another in the back, making the crunching sounds you mentioned
love this.
While printing cases for the buttons you could create embossed names/descriptions for the buttons on the 3D model :)
I watched this in two sittings...
Can't help but notice those Chinese Leadshine ELP-750 Ethercat drives are already gone or hard to get.
It's hard to tell with Chinese knock-off EtherCat stuff...I've heard good things (cheap) and horror stories (had to replace after a few months, weird firmware bugs, motor bearing failures etc.). I'm sure Tony will tell us if it's breaking down over time. It's always suspicious when you see this stuff being hawked on eBay, AliExpress, etc. Hopefully it will all work great for him. Thanks for nice video!!
Weren't you having issues with the y axis essentially right after you got it? Could there be a underlying issue with the u axis that's causing the ball nut to break?
Honestly Tony, hearing you find your voice, grow more comfortable in your videos, and learning so much from you, has been awesome. :D
Fantastic video. A bit more on servos.. Not all of them have batteries. The reason that servo has a battery is because it has an absolute encoder (this is how it can "remember" its position through a powercycle.) Some servos, like Allen-Bradley servos, use an incremental encoder but rely on the controller to maintain reference. In the machinery I work with on a daily basis, German paper converting equipment, there are many servo-driven elements. Since they're using incremental encoders, we have reference sensors on particular parts of the machine that the controller uses to "home" an axis. I've recently started watching your videos regularly and I'm really impressed with the amount of information you're relaying to the audience. I've learned a ton from you and I really appreciate the content. I've decided it's time to get a mill myself and stop using the ones at work for home projects. Originally, I wanted to get a CNC mill but the more I watch your videos and a few others on IRworld, I think I'd be better off getting a manual mill and adding CNC capability. This video may very well have catalyzed that idea. Thanks again for the great information and the laughs!
those are tapered gibs your y axis has there those can tighten up under motion if they have some play. now they should have either one screw pushing on either side which is a system that pretty much eliminates play in the gib but most of the time, for ease of use, they have one screw that fits into a groove to push the gib in and out ant if some part of that is worn the gib has some play to tighten up under load and screw up a ball screw in one way only
gliding ways can also work in rapid back and forth motion pretty well if they're lubricated enough, which they likely are in this case. still, scraping the ways can go a long way in keeping the oil on the ways under rapid motion. don't worry about the geometry, it should be finde the way it is and just a few crossing scrapes every half an inch is enough for those chonky guideways
Tony, do you know if your motion control system is driving those servo drives with step/direction or in torque mode with 0-10v inputs for speed and torque?
Those leadshine servos are tiny - amazing. I've a ton of experience with the Lichuan ones, they're fantastic value, I think we pay around $250 for a 750w drive and motor package.
11:35 When you got to tell your folks some bad news.
Question, has MAHO called and asked for their machine back? :)
5:21, If you pay close attention, you will see the sleaf ripple against the hydraulic-line... just saying
Did I just watch a 48 minutes long video about some cnc machine?
Hey Tonny! Isn't that weird sound in 5:37 a sound of a steel thingy rubbing on white plastic thingy?
My mechanic training is nearly a decade old, I am not good at electrics and useless with electronics, yet I've enjoyed the whole thing (though my two braincells went "nope!" for the electronic part) !
I sure miss This Old Tony. Nice that the new CNC guy kept the same hands and voice, though....
THIS OLD IS THIS OLD TONY I FELL IN 🖤 WITH! welcome back misterMR
do you want your conduit wire opening to fill with chips? Cover them up....
So who are the two others that made it to the end?(; I love these longer videos there just so packed right to the tippy top with information. And it’s the good stuff too, not like the crap you see on the news.
That was incredible Tony. I have no idea what you're talking about and yet I enjoyed every minute. I have attempted to watch "gone with the wind" (oh Ashley, oh Ashley) a couple of times but given up before the end! Not with this video! I am the 4th person to watch it all. I even think I could fool someone into thinking I know the difference between savoury and fruit loops! Thank you for making me a better person 💝😘
