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

This Old Tony relly blows my mind! Where are you based out of?

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.

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 IRface, 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

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 💝😘

This old Tony. Try an Igus ball screw instead. No crunch and cheap and tough

Maho, Maho man, i'd like to be a Maho man. I guess the guy in leather was German?

WOW, I'm with Ron Covell, , , ALL IN ONE BREATH, Amazing.

5:40 Do you think that ah perhaps the crunch sound is coming from those two ribbed pipes rubbing together in the background?

Epic videos on this conversion Tony! So, if you here back at square one, would you do it again? (Ignoring all the lovely content you've created at the same time) Is buying an old CNC Bridgeport a better starting place?

"Green Mile", love it!

"Why do I watch these videos? I HATE machining!!" Also me- hey look a new TOT video.

Personally, I'd change out the gravel in the " Y" ballscrew. I tend to like smooth river pebbles over crushed granite.

Boy those overhead shots are hard on the vertigo!

I don't know anything about machining, milling, cnc, turning what have you at all. Barely have a concept of what those terms even mean. I guess its either Tony's style of presentation or me being a masochist that not only had me sitting through the entire video but even put my automatic porn downloader on pause for 48 mins.

A 48 minute video is not long. There is some idiot on YT doing 90 minute videos and not even apologizing, rediculous! Great video Tony as always! ATB, Robin

The color is RAL6011.

The paper trick is still the best for 3D printing! Automatic bed leveling is kinda meh.
