Of course! Other videos you ask "Does this content matter to me?" These, you ask "Does This Old Tony matter to me?" And the answer is YES. Yes he does.
Tony, your idea for the map -> invert -> cut inversion -> stick together process at the end makes me think you could machine some *ridiculous* halves of geometrically complex billets for the damascus/forge-welding guys to then twist and fold. I don't know *what* geometry you'd want to stick together, yet (with a lot less work than it takes to make those 'mind-bendingly close' EDM clearances), but I'm really excited thinking about novel steel-also-steel-but-different composite structures you could make, then acid-etch (or CNC-TIG braze some aluminum bronze filler onto, too, for gold-colored parts?). I dunno, I need a few years to build the 'too small for a building permit' shop in my parents' yard and work my way up to any of that, so I'm hoping for some instant-er gratification.

TOT actually broke the Spacetime Continuum. What you were unaware of is that the person that appears in these videos as TOTs son in this multiverse is actually TYT trapped in this dimension.
I frequently do CNC circuit board engraving and have been using a similar technique for many years, but since the circuit boards are conductive and copper is relatively soft it doesn't need a special probe, instead the probing relies on the engraving bit making contact with the copper surface to form an electrical connection to let the software know the bit is touching the surface. Mapping the surface is essential for good results as the engraving depth is only 50um in order to make very fine traces. Cheers, Jake
I was about to comment the same thing. Without probing and surface mapping, even slight unevenness in copper clad or in mounting would results big variations in the width of engraved tracks. This trick also works with other non-conductive materials, if you glue thin copper/aluminium tape over the surface. Just remember to connect the probe cable to the part, once I forgot to do that and CNC machine happily turned circuit board into punch card😅.
How can I be so sure I will never use this in my life time but still enjoy this video more than any other commercial content created during last 30 years? Happy new year TOT!

Also I started 3d printing recently and I have to say that Tony actually helped me in unconventional ways. You helped me developed my designing mind and helped me approach certain issues in a new often easier way. so thanks! and keep up the good work!

I 100% concur with your first sentence. ToT is the only "bell" I have activated, because with him I want to watch the video as soon as possible. Others, even some of my oldest and dearest channels, I can wait a few days until I have some breathing room to enjoy the video at my own pace. But with ToT, I know I will watch it a second and third time to really let the humor and information sink in deep. I think I've watched half his videos three times, a quarter even more and many I'm only partially interested at least one or twice.
Same, i was trying to figure out if he just set the cut depth more shallow over the higher surface. Im glad i know the truth now, but wizardy is cool too
I've had the same thought! A properly calibrated triangulation laser scanner could scan the whole surface is seconds, and very reasonably get sub-mm precision. If you used an time-of-flight setup, you'd probably be able to get nano-meter precision, but that would get very expensive, haha
This is so cool! As an engineer, I was able to do a similar thing in my job. I took a 3D model of a computer board, and took the surface heights of all the components to make a negative, with over sized holes. That negative would contact all the parts of the board while avoiding the delicate components. Then you can put weights on top of the board to ensure the board is contacting the entire surface when gluing to a heat sink.
We do this in astrophotography too. :) The calibration is done using "flat frames" that capture the non-even illumination of the field due to optical limitations.
We do this in microscopy too! You want to generate a mosaic image of high-res images of a larger sample, and all have them in focus, even if the specimen holder, the specimen itself and the coverslip aren't flat? Surface mapping ftw!

Darks are essential for correcting hot or cold pixels, while bias is more about finding the pedestal (or "DC" component, if you like) of the read out values.

Perfect timing, just about to have my dinner, here in Scotland. Something to watch, and eat my curried haggis supper. So I'll say, great video 5* before watch it in a minute and expect to be entertained.
Some 3D printers have this technology too. Both of mine probe the surface of the print bed before they start. One uses an induction sensor and one uses a physical probe. They're also set up to zero out the surface as the print height increases.
I use manual mapping on mine. Initially I used manual mesh mapping, which is a measure the points then your good to go... until you clean your machine or nudge it and change the geometry in subtle ways we can't even see with our human eyes. Moved on to billinear mesh leveling which allows me to specify a z-offset and tilt to adjust it when things change. Pro-tip do not use a 10x10 grid, that's 100 points you will have to measure multiple times to get it honed in, stick to something more sane like a 3x3 unless you really need that level of accuracy.
I was going to mention that until I saw your post, so I'll just expand on it here. ;-) In the 3D printing community this technique is normally called "mesh bed leveling". There are various methods of probing the bed surface. All current Prusa printers and some others use inductive sensing to find a metal underlayer of the print surface (and thus require a z-level offset to account for the thickness of any surface layers/treatments on the metal). Others use a BL Touch (or similar) mechanical probe. And the newly announced, but not available yet, Prusa XL printer uses a strain gauge in the hot-end assembly to touch the surface with the nozzle to probe (there may be other printers that do this, but I'm unaware of them). Several of the 3D printer firmware families (I know Marlin does, I suspect Klipper does but don't know for sure, not sure about the other firmware families) have the mesh leveling built in and use gcodes like G29 or G80 to initiate the probing routine. Often the way the 3D printer firmware applies the surface probing is they use the full value of the mesh to the first layer, and slowly over the next few layers decrease the effect of the surface mesh z adjustment until it isn't applied anymore.
Checking what year it is was perfect! The fact that we're two weeks away from 2022 when it still feels like 2019 boggles the mind! p.s. I definitely wouldn't be against another christmas story episode :) one of my favourites.

Hands down my favorite youtuber. If you pressed me I'd admit AvE is my hands up favorite youtuber. They both released a video in one day and now i feel like ricky bobby. Ive never felt so conflicted over what to do with my hands before. And that includes during high school.
I've been waiting for someone to explain this to me in a way I can partially understand and nod my head like I know what you are talking about.... Thanks a lot ToT, I'm so much smarter than I was before I watched this video.
This video was perfect for me. I have been curious about how to do this for awhile (surface mapping) to engrave some components. I just didn't know where to start looking to get more info. Now armed with the correct terminology I can find out more. Plus I was dying when you said "It turns out I'm the reason I can't have nice things" Hope that probe tip replacement works out and thanks for another awesome video. It always brightens my day when I see a new video pop up in the notifications.
I made a cart with a pair of linear gauges facing each other to accomplish this same curved surface mapping on drum cymbals, but the pair of gauges means I get thickness too. The cymbal tracks with a linear scale so I can re build the point cloud. Works like a charm!
Glad to see cmm scan technology applied to cnc now. Now if my customers who send me one half of a broken casting would get this my world would greatly improve. They could scan the actual half, increase for shrinkage and invert for the missing side to send a solid complete pattern
I use a manual method of this on the cnc at work. we have some dodgy plastic that comes in sheets of 2440mm x 1220mm and i machine both sides to make tops and bottoms for speaker cabinets. this plastic is recycled and has a surface that fluctuates up and down up to 3mm, nightmare to get countersinks to be flush with the surface, so, i probe (this probe can only do z check) every location i have to put a countersink in. what i do is every time the probe touches off i pass the z value to a variable, my machine they are E### and just increment the number by 1 for every new location, then when i go to countersink i just call the offset for that location. The software i use doesnt have the ability to do surface mapping, the machine is 30 years old. and this was the only way i could do it efficiently and fast. the machine has a cassette drive and floppy disk lol. Wish i could use fusion and mach. Im trying to blag my boss to give me and the team fusion, and he said yes but hes dragging his feet on it lol. As for mach i dont think we can convert the machines OS. its too old. Thanks for the excellent vid as always. love you T.O.T.
yeah, inverse perspective transformation would be hard to do without a PDP11 to do the complex multiplications used in linear algebra (lots of matrices), you couldn't do the derivative analogically (unless you wanted to build a Babbage's analytical engine yourself). better stick with modern digital electronics. I don't understand any of this about gcode, but I do understand the mathematics because I write computing graphics software for 3D point cloud reconstruction. its just a world matrix transformation of the gcode points into the surface mapped, we are literally warping the world space.
@Luiz Felipe thats really interesting, i didnt think of it as a matrix. did a bit of stuff on matrices at uni when i was studying computer games software development. thanks for that inciteful reply
As an engineer/physicist new to CNC and basically unaware of precision and leveling I fixed all my alignment problems with a 3D printed a version of the Raith? I think? multi-axis probe...That tool with a raspberry pi + 1000+ lines of code (in bash script bc python is the worst) to map, analyze and change gcode, and drive my machine basically gave me the ability to make features with 100ish micron precision/repeatability in acrylic/PC...Then I got a resin printer and my mill has been gathering dust...Again ToT hits on a subject so close to my heart :)
Oh dear lord I forgot how fun it was seeing a new TOT video and taking a break from what I'm doing to watch it, man we missed you. It's good to be back on speaking grounds Tony
Blue Probe... drove one of those for many years and loved that car into a rusty forlorn high mileage heap. Was moved a little to see one immortalized into your video. Excuse me while I go wipe away some fond memory sniffles.
The surface map file that it outputs is pretty much CSV format, as far as i can gather, very easy to parse. I could whip up a tool to convert it to a mesh really quickly if someone gave me an authoritative example file.
This principal would be awesome to use for something like a low-cost router build where big machinery/expensive operations aren't available (like flattening the gantry face on TOT's first router build). Spend some time with an indicator manually creating your own surface map of the tubing installed/loaded and have the software make it perfectly flat for you.
Yeah, same here. I have run CNC machines in the past but I am mostly stuck with manual machines without even DRO. Still pretty pleased with stuff we can turn out though. I machined a custom railed PCC receiver a few years back, it had about a foot of 1913 rail on top. I cut every single one on the wheels. Jog .375, cross, jog .019, return, jog .375, cross, jog .019, return, for 31 individual slots. Came out clean and to spec.
Love your videos! It's amazing to see what can be done with modern hobbyist-level CNCs. I did similar "map the surface" projects using Fanuc CNCs and Renishaw probes. The most complex mapped large pipes (up to 20m [787"], 2m diameter) so we could machine features accurately. 2-3 hours of probleing, hundreds of data points, all done in Fanuc macro language and PLC. My best probe story... a careless operator cracked the glass body on a TS-27R probe. Still worked, accuracy wasn't noticeably affected, with a replacement probe a few weeks delivery. But the humidity (this was in India) would seep inside the body, condense on the inside surface of the glass, and could eventually cause problems with the electronics. So I had someone provide a condom; poked a hole in the tip, rolled that sucker on, problem solved! We used that probe for at least 6 months, replacing it every few weeks as required. I tell this story anytime I see a probing videos. So this may be a repeat. Cheers!
Merry Xmas and a Happy New Year to you and your family, Tony. Here's to a way better 2022! [edit] That hammer head joke! There are baby hammerheads everywhere hammering on the boat of the guy that should have bought a bigger boat because of that joke.
I nearly rolled my eyes when you explained the intro engraving. Not gunna lie, I loved that joke, and would totally do that to my hammers if I was able to God I love the dad jokes!
@@MrKotBonifacy I literally just watched this video when I got the notification for this one :) Personally, I‘d love to see a feature film length video of ToT just rambling about… Let’s see what the 1M sub special will eventually look like!
I am wondering why the engraved letters appear to have such perfectly square corners when the tool used is round. If you look at the ends of the horizontal bars of the letter E @3:40 the ends are sharply defined and squared. It also looks like the tool depth was enough to make the full width of the characters in one pass. That is not making sense to me.
The v-shape of the tool is used at different depths to essentially get different radii in the corners. You can see as it cuts that the tool is moving up and down more than the height map would require so that it can engage different amounts of the tool. Close to the edges of the letters the tool raises up until basically none of the tool is engaged. Engraving bits can't make flat bottoms while retaining that tight radius, so if you needed the engraving to have a flat bottom for whatever reason you would have to use an endmill with an acceptable radius for the corners. Most likely you would end up with a much less rigid tool that way, and it would have to cut much more slowly or you would need tool changes.
@@joshwillis1726 Goodness! Yes I can see how that works, and it is very cool. CNC of some sort is something I'd like to have in my (mainly wood) shop, but I have not been sure how much I would use it. It's that sort of added value you described that makes it a lot more interesting.
I'm curious about this too. Josh's explanation makes sense if there's multiple passes, including extra cutting at each sharp vertex, but we just see a single, continuous motion. A truly sophisticated servomotor spindle and CNC control could "map" where the cutting edge of the tool is, and scrape that tool edge into and out of a corner to get this effect in a soft material, but that's not the case here.
This Old Tony you have to know this... seeing that your new clip is on youtube is like finding 20 in a pocket of a jacket you havent worn for months, its like a one more candy when you'd swear you've ate them all, whole next level of pleasure..

I am here for you TOT! Well you and AvE... oh and Clickspring... Mr. Pete. Tony, I fear that I may have been less than faithful these past several years but I thank you Brother, for the things that you have taught me. Happy New Year to you and yours.
Sweet. I was bored because of a windstorm power outage and first thing in my notifications is Old Man Tony with his old man hands in the spotlight 😁. Perfect timing.
This is something I have seen in 3D printers that allow it to work with slightly warped or unlevel print beds. I always wondered why that didn't seem to exist for cnc machining. Turns out it does! Thanks for the vid.
Might be nothing new to some people but I didn’t know about it and now I do! Thanks Tony! My favorite you tube channel. Your videos are great. So glad your back!
You breaking the probe the first day made me laugh 😂 my current job is basically running a machine shop solo with a few machines and they have a nice haas mill with a sweet probe that I have yet to break but his day will come😇
Not only are we all willing to map our surfaces, the guy demonstrates the process while being more and more good looking. I see melting hearts everywhere now
Hello Tony nice to hear from you I hope you are better than ever! Keep going and a wonderful Christmas for you and all your familly !!! By the way great video !!!
Finally! Someone has figured out a way to use the warped wood being sold at Home Depot!
I think they’re sold out of that as well. I wonder if warped wood sits in a shipping container for months on end, comes out straight??
...It's not warped, it has a surface map integrated, it's a feature !

All current Prusa printers and some others use inductive sensing to find a metal underlayer of the print surface (and thus require a z-level offset to account for the thickness of any surface layers/treatments on the metal). Others use a BL Touch (or similar) mechanical probe. And the newly announced, but not available yet, Prusa XL printer uses a strain gauge in the hot-end assembly to touch the surface with the nozzle to probe (there may be other printers that do this, but I'm unaware of them). Several of the 3D printer firmware families (I know Marlin does, I suspect Klipper does but don't know for sure, not sure about the other firmware families) have the mesh leveling built in and use gcodes like G29 or G80 to initiate the probing routine.
Often the way the 3D printer firmware applies the surface probing is they use the full value of the mesh to the first layer, and slowly over the next few layers decrease the effect of the surface mesh z adjustment until it isn't applied anymore.
15 minute break at the factory and a 14 minute video. Perfect!
"Hey Raul, get back on the line! And what are you grinning about?"
😂
Personally, I don’t mind at all if Tony pumps out a few wood videos. I’ll watch em all!
If he takes up crocheting I'll still watch. I don't give a rat's ass about what he does... as long as he narrates it! :P
His machinist friends will nutcheck him
I wood watch them as well.
Checking what year it is was perfect! The fact that we're two weeks away from 2022 when it still feels like 2019 boggles the mind!
p.s. I definitely wouldn't be against another christmas story episode :) one of my favourites.
I can't begin to explain how excited I am to be notified you just uploaded! Thank you!!

I'm so pleased to have you back lately. Thank you for your videos, they are always top notch.
Using The Clapper to start a band saw is a stroke of genius. If you have already proven yourself incompetent with a band saw, then you can't clap with that one remaining hand, and your band saw privileges are de facto revoked. Brilliant!
Thank you for the comedic pause after the hammerhead shark. I didn’t need the time to get it, but was able to enjoy it longer!
28 years machining and I never knew this was possible, Great Video thanks for sharing mate 👍
This is just like auto-bed leveling on a 3d printer. Awesome stuff Tony!
Welcome back Tony
New sub. here - you are a very clever man that has excellent communication skills on this topic - look forward to all of your future videos and binge watching the previous. Best Wishes from Australia.
You end up coming back for the endless stream of dry dad jokes and funny little skits. I found him because he did a collab with Wintergatan (mechanical instrument building channel) and not because I have an interest in machining... you just get hooked so fast on his ever witty narration :P
Love this surface mapping! With each video of yours, I feel I'm being pulled closer and closer towards CNC..
..not the same, but I'm still dreaming to implement a good solution for non-planar 3D Printing, using 3 axis... 😌
There's a video or two out there with non-planar 3d printing. You'll always be constrained by head geometry. What are you thinking you'd like to do?
@@chaos.corner make the head swivel over 2 axis :p
@@markkalsbeek5883 That would be 5 axis then
here's an idea: imagine a bubblegram, but the medium can fall away, and the "bubbles" become solid like a sintering 3d printer.
TOT the Bob Ross of material shaping (mainly metal), humourous yet informative & very relaxing! (happy accident? Who knows) Just know I missed him while he was off air & really glad he's back :-)
Hands down my favorite youtuber.
If you pressed me I'd admit AvE is my hands up favorite youtuber.
They both released a video in one day and now i feel like ricky bobby.
Ive never felt so conflicted over what to do with my hands before. And that includes during high school.
So good to have you back TOT. Hope all is well or healing with you and yours.
These always impress me watching them lightly move around, I feel like if I wrote the code it would just slam full speed into the work piece
I love you, Dad.
I've been re-watching a your old videos just to get my TOT fix. So happy you're back :)
Way over my head, but I still enjoy watching. Thanks Tony,
I've been waiting for someone to explain this to me in a way I can partially understand and nod my head like I know what you are talking about.... Thanks a lot ToT, I'm so much smarter than I was before I watched this video.
This video was perfect for me. I have been curious about how to do this for awhile (surface mapping) to engrave some components. I just didn't know where to start looking to get more info. Now armed with the correct terminology I can find out more. Plus I was dying when you said "It turns out I'm the reason I can't have nice things" Hope that probe tip replacement works out and thanks for another awesome video. It always brightens my day when I see a new video pop up in the notifications.
I made a cart with a pair of linear gauges facing each other to accomplish this same curved surface mapping on drum cymbals, but the pair of gauges means I get thickness too. The cymbal tracks with a linear scale so I can re build the point cloud. Works like a charm!
I love your CNC vids. It's what brought me to your channel and I stayed for the content.
Glad to see cmm scan technology applied to cnc now. Now if my customers who send me one half of a broken casting would get this my world would greatly improve. They could scan the actual half, increase for shrinkage and invert for the missing side to send a solid complete pattern
Use the tool itself as a stop. command it to the position you want and stop the block against it.
I will literately never ever use any of the skills Tony teaches here in his videos. This doesn't stop me from thoroughly enjoying all of them. LOL
In bed recovering from a surgery this morning and was so happy to see a new TOT video when I woke up!
I use a manual method of this on the cnc at work. we have some dodgy plastic that comes in sheets of 2440mm x 1220mm and i machine both sides to make tops and bottoms for speaker cabinets. this plastic is recycled and has a surface that fluctuates up and down up to 3mm, nightmare to get countersinks to be flush with the surface, so, i probe (this probe can only do z check) every location i have to put a countersink in. what i do is every time the probe touches off i pass the z value to a variable, my machine they are E### and just increment the number by 1 for every new location, then when i go to countersink i just call the offset for that location.
The software i use doesnt have the ability to do surface mapping, the machine is 30 years old. and this was the only way i could do it efficiently and fast. the machine has a cassette drive and floppy disk lol. Wish i could use fusion and mach. Im trying to blag my boss to give me and the team fusion, and he said yes but hes dragging his feet on it lol. As for mach i dont think we can convert the machines OS. its too old.
Thanks for the excellent vid as always. love you T.O.T.
yeah, inverse perspective transformation would be hard to do without a PDP11 to do the complex multiplications used in linear algebra (lots of matrices), you couldn't do the derivative analogically (unless you wanted to build a Babbage's analytical engine yourself). better stick with modern digital electronics.
I don't understand any of this about gcode, but I do understand the mathematics because I write computing graphics software for 3D point cloud reconstruction. its just a world matrix transformation of the gcode points into the surface mapped, we are literally warping the world space.
you are basically doing a lerp, a linear interpolation of the 2 points (current, aka offset, and the recovered), that kinda works. nice trick.
@Luiz Felipe thats really interesting, i didnt think of it as a matrix. did a bit of stuff on matrices at uni when i was studying computer games software development. thanks for that inciteful reply
As an engineer/physicist new to CNC and basically unaware of precision and leveling I fixed all my alignment problems with a 3D printed a version of the Raith? I think? multi-axis probe...That tool with a raspberry pi + 1000+ lines of code (in bash script bc python is the worst) to map, analyze and change gcode, and drive my machine basically gave me the ability to make features with 100ish micron precision/repeatability in acrylic/PC...Then I got a resin printer and my mill has been gathering dust...Again ToT hits on a subject so close to my heart :)
Oh dear lord I forgot how fun it was seeing a new TOT video and taking a break from what I'm doing to watch it, man we missed you. It's good to be back on speaking grounds Tony
So glad you are back in action TOT. Missed you a bunch!
love wood videos wish you would do more woodworking tbh .. its really cool to see a machinists perspective to woodworking
tried this on super janky chinese router to do pcb milling ages ago - weirdly accurate! thanks for another great video!
Blue Probe... drove one of those for many years and loved that car into a rusty forlorn high mileage heap. Was moved a little to see one immortalized into your video. Excuse me while I go wipe away some fond memory sniffles.
This Old Comedian.
The best informational comedy channel on the internet.
So now the question, can you then export your surface map from Mach 4 into solid works, so now you have a 3D scanner? :)
The surface map file that it outputs is pretty much CSV format, as far as i can gather, very easy to parse. I could whip up a tool to convert it to a mesh really quickly if someone gave me an authoritative example file.
Holy crap, I haven’t been this excited to click on a notification in a long time.
Ho-Ho-Ho. Merry Christmas, Tony. All my best to you and yours. Thank you for all the video gifts over the past year.
I like the wood projects. I like the variety you provide.
This principal would be awesome to use for something like a low-cost router build where big machinery/expensive operations aren't available (like flattening the gantry face on TOT's first router build). Spend some time with an indicator manually creating your own surface map of the tubing installed/loaded and have the software make it perfectly flat for you.
This is basically how auto-leveling 3d print beds work. It probes the bed and applies that mesh to the gcode to move in parallel to it.
I'm a gunsmith, all manual machining. I dont even know how to turn on a cnc machine but still love these videos just because it's TOT.
Yeah, same here. I have run CNC machines in the past but I am mostly stuck with manual machines without even DRO. Still pretty pleased with stuff we can turn out though. I machined a custom railed PCC receiver a few years back, it had about a foot of 1913 rail on top. I cut every single one on the wheels. Jog .375, cross, jog .019, return, jog .375, cross, jog .019, return, for 31 individual slots. Came out clean and to spec.
@@karatos I don't have the luxury of a dro on either of my two lathes or my mill. But I damn sure set indicators all over lol.
So glad youre back!! Loving having your videos again!
Love your videos! It's amazing to see what can be done with modern hobbyist-level CNCs. I did similar "map the surface" projects using Fanuc CNCs and Renishaw probes. The most complex mapped large pipes (up to 20m [787"], 2m diameter) so we could machine features accurately. 2-3 hours of probleing, hundreds of data points, all done in Fanuc macro language and PLC.
My best probe story... a careless operator cracked the glass body on a TS-27R probe. Still worked, accuracy wasn't noticeably affected, with a replacement probe a few weeks delivery. But the humidity (this was in India) would seep inside the body, condense on the inside surface of the glass, and could eventually cause problems with the electronics. So I had someone provide a condom; poked a hole in the tip, rolled that sucker on, problem solved! We used that probe for at least 6 months, replacing it every few weeks as required.
I tell this story anytime I see a probing videos. So this may be a repeat. Cheers!
Merry Xmas and a Happy New Year to you and your family, Tony. Here's to a way better 2022!
[edit] That hammer head joke! There are baby hammerheads everywhere hammering on the boat of the guy that should have bought a bigger boat because of that joke.

OMG! I just got the hammerhead joke. More caffeine.
Never considered this, pretty cool to see how it works. -future mechanical engineer
Same same
When I first saw your tittle I wondered how you would integrate lidar with CNC, or the other way around...
So enjoyable watching your vids!
The hammer joke absolutely killed me. I couldn't breathe.
I nearly rolled my eyes when you explained the intro engraving. Not gunna lie, I loved that joke, and would totally do that to my hammers if I was able to
God I love the dad jokes!
ToT: Which wizard did you use for the surface mapping? Was it Gandolf, Merlin, Dumbledore? How how did you summon the wizard?
--Thanks!
The pause to let us chuckle at "hammerhead" was brilliant. Well done sir. You should have a TH-cam channel.
I was having withdrawal symptoms waiting for another video from you! Missed you dude!
can you still *do* the introductory ted talk, eventually? :)

LOL, I'd to see that one too. "How I became This Old Tony", would start out with him crawling on the floor picking up metal chips and eating them.
He did, methinks... at his 100K subs video... : ) Time flies when you're having fun, eh?
@@MrKotBonifacy I literally just watched this video when I got the notification for this one :)
Personally, I‘d love to see a feature film length video of ToT just rambling about…
Let’s see what the 1M sub special will eventually look like!
I am wondering why the engraved letters appear to have such perfectly square corners when the tool used is round. If you look at the ends of the horizontal bars of the letter E @3:40 the ends are sharply defined and squared. It also looks like the tool depth was enough to make the full width of the characters in one pass. That is not making sense to me.
The v-shape of the tool is used at different depths to essentially get different radii in the corners. You can see as it cuts that the tool is moving up and down more than the height map would require so that it can engage different amounts of the tool. Close to the edges of the letters the tool raises up until basically none of the tool is engaged. Engraving bits can't make flat bottoms while retaining that tight radius, so if you needed the engraving to have a flat bottom for whatever reason you would have to use an endmill with an acceptable radius for the corners. Most likely you would end up with a much less rigid tool that way, and it would have to cut much more slowly or you would need tool changes.
@@joshwillis1726 Goodness! Yes I can see how that works, and it is very cool. CNC of some sort is something I'd like to have in my (mainly wood) shop, but I have not been sure how much I would use it. It's that sort of added value you described that makes it a lot more interesting.
I'm curious about this too. Josh's explanation makes sense if there's multiple passes, including extra cutting at each sharp vertex, but we just see a single, continuous motion. A truly sophisticated servomotor spindle and CNC control could "map" where the cutting edge of the tool is, and scrape that tool edge into and out of a corner to get this effect in a soft material, but that's not the case here.
This was dope Old Tony, Glad to have you back!
This Old Tony you have to know this... seeing that your new clip is on youtube is like finding 20 in a pocket of a jacket you havent worn for months, its like a one more candy when you'd swear you've ate them all, whole next level of pleasure..
You have a way of making those hands feel like they are pointing right at me despite those million other sycophants vying for your favor. Don't worry, I know that they mean nothing to you. I am here for you TOT! Well you and AvE... oh and Clickspring... Mr. Pete. Tony, I fear that I may have been less than faithful these past several years but I thank you Brother, for the things that you have taught me. Happy New Year to you and yours.
Sweet. I was bored because of a windstorm power outage and first thing in my notifications is Old Man Tony with his old man hands in the spotlight 😁. Perfect timing.
This is something I have seen in 3D printers that allow it to work with slightly warped or unlevel print beds. I always wondered why that didn't seem to exist for cnc machining. Turns out it does! Thanks for the vid.
My recommended adverts have gone straight back to machine parts and CNC companies thanks to these I missed them lol
Might be nothing new to some people but I didn’t know about it and now I do! Thanks Tony! My favorite you tube channel. Your videos are great. So glad your back!
So happy to see you around again. Just the perfect Christmas gift!
Cool. It's like the BLTouch probe on my 3d printer.
thank you for your content. you are by far my favorite creator of content, and by that ...I mean content creator
The impossible dream, now perfectly possible.
Great , hugs from Brazil
Mate that is Fantastic, add the "this old Tony" touch, now it's just EPIC
Man I laughed so much with the last emoji face XD. I'm so happy to have you back!!!! Nice video as always! Best from Spain.
Gosh it made my day to see a new video out from ToT!
You breaking the probe the first day made me laugh 😂 my current job is basically running a machine shop solo with a few machines and they have a nice haas mill with a sweet probe that I have yet to break but his day will come😇
Not only are we all willing to map our surfaces, the guy demonstrates the process while being more and more good looking. I see melting hearts everywhere now
I inspect roads and bridges for a living, will never CNC or machine anything but yet here I am.
Love me some This Old Tony
That intro was soo funny, I hammered my head on my (CNC) table ...
I literally gasped when I saw that you just uploaded. Thanks TOT for creating excellent videos
Great to have you back Tony, happy Christmas and keep up the fantastic video's
"We have no choice, we are on a time loop now" a deterministic view of reality
Thanks TOT! What once was magic now is explained, and both of my brain cells are bruised from touching!
Hello Tony nice to hear from you I hope you are better than ever! Keep going and a wonderful Christmas for you and all your familly !!! By the way great video !!!
Damn, you're the only TH-camr that gets my humour.
Mapping is Awesome. So easy for the machine, once it "learns". Cool!
I have to say that your stories (video's) are always fun as well as very fully packed with good information. Thank you for helping me to enjoy life.
