Excellent tutorial ...simple explanation of each step and their letter code. This 75 yr old beginner even understood, learned and enjoyed. Great Narration.

[@jasonbirch1182]

Thank you. My first real g code lesson. It made perfect sense. I wish you had more.

[@TedDanzig]

Watching you demonstrate and explain was better than most of the literature I’ve found. Thank you.

[@derryafandi7717]

Thank you bro, still good on 2023

[@whocaresidontcare2116]

This was very helpful and clearly pointed out at a nice pace. Thank you for not adding music to the background.

[@ricklovoi1520]

Finally someone spends the time to really explain !! I found this awesome for someone who never used a CNC machine. Looking forward to learning this new skill!!Thank you !!!!!

[@obiscotchkenobi6195]

Thank you sir. You finally explained circular interpolation in a way that us normal folks can understand. Please, please, please upload more videos!

[@MisterFizz]

Very helpful for an absolute beginner. Thank-you for taking the time to lay it all out so well, step-by-step. I found the presentation guide me very precisely through the process and left me with a strong base level understanding of each step.

[@MrWallace803]

Great tutorial. I tried to learn radiuses from the Haas manual, but my head almost exploded. This lesson explained it perfectly.

[@58browning40]

Very good tutorial. I have been programming CNC lathes for many years but have limited experience programming milling machines. This video helps me understand mill programming better. Thank you!

[@AbhishekRaj1992]

58browning pleae help me to learn

[@DucTran-ih4ck]

Now I understand I and J so clear. Thank

[@johnzhang691]

I skipped the lecture at school and found this fundamental introduction very clear and helpful.

[@josezolorza406]

I go to NTMA Training Center & just started learning G&M Codes, it is very helpful to look at videos like this one. I find it sometimes better explained from another person than my teacher, Thank you for this video.

Great video! The illustration of g00, g01, g02 is extremely clear. Thanks for your time.

[@paulm5302]

Outstanding Tutorial. Please keep them coming... Thank you, I look forward to more CNC mill tutorials from you soon.

[@althomas6045]

titans and hass do not come close to the quality and safety of your code or the qaulity and depth of your explanations. well done. i've got 42 years in the trade and 37 as a programmer.

[@NyourfaceProductions01]

Good explanation of each move. This is a very good starting lesson of Gcode. I am an untrained machinist but really want to get into CNC for home and eventually convince my employer to get a small CNC 3D router.

[@STSCNC]

This was well done and easy to follow, Thank you

[@markwilliams4015]

EXCELLENT Video! Excellent Visuals! Excellent description! Couldn't ask for anything better. Keep up the good work!

[@robertdolan8959]

Really enjoyed the video, today was my first day of CNC Class at community college and the instructor went very fast through the codes. I like how you took your time to thoroughly explain the methods and not go too fast, thx again!

[@Dsmiffb]

sad thing is I had 3 classes dedicated to CNC programming at my college (automated manufacturing major) and you explained everything much better in one video. lol. very informative. been working for over a year in addition to my degree and I am always learning. it's a great thing to know.

[@INFIDEL82AA]

David... I can say the same thing, in regard to my CNC classes. My instructor was trying to explain or "Teach" our class G-Code, as if we all had SOME experience writing it. None of us had! We were all taking beginner classes. Then he would get all pissed, when we didn't get what he was saying. Some people just suck at instructing, on a level that will allow someone to learn. Like you stated, this 25 minute tutorial has explained things far better to me than my CNC "College Level" instructor ever could! Good luck! I hope things are moving forward for you. I absolutely love this shit!

[@jimjam1719]

titanium cranium- i agree with you, my instructor kinda mumbles when he talks, or should i say, he speaks very lowly, i.e. a low volume, hard to hear him, and i am just sitting 2 chairs over from him, and he tells us coming from his experience, where as we are newbies, he doesn't get mad, but i can tell he is prolly thinking that we are stupid to a degree, he has to keep reiterating himself or repeating everything but he doesn't explain it in simple terms, he can only explain it in experienced terms, in other words,,,, i'm not sure he is cut out to be a teacher, some people can teach, others can't. i think he is more concerned about the xtra money he is making from teaching on the side of his cam programming job. btw- i love this shit too.

[@Pidalin]

At the end, you have to find out everything in practice by testing, some lessons will taugh you maybe how to start the machine, not how to actually program it. 😀

[@seatlanta]

Good job. Clear graphics. Thanks for taking it slow.

[@Montoyee]

Thanks so much for this video! This really helps me understand what the bosses are babbling about when they're setting up at work!

[@noahberger8760]

Eric Montoya , What is it you do at work then, if the bosses are setting it up? I sincerely wish to know. So many CNC shops around here and I need to do something, since no one else seems to be hiring. I wish to know how to approach these guys with no experience but a willingness to learn.

[@duanedean3256]

Ha, best explanation of I and J. Could never understand it till now. So simple.

[@jimjam1719]

duane dean- ya, i finally understood i and j just now with this video, couldn't with my instructor, but with this video, now i can.

[@Warpfield]

Just now coming to this, 3+years later. Very informative.

[@MakeSomethingCNC]

this is what i have been looking for! very well spoken and layed out.

[@mathewwhittle10]

First thumbs up I've given for ages... still foxing my brain, but this allows a person to soak it all in. Thanks.

[@jbbauer0]

Watched a couple other videos on G02. This one really hammered the nail in. Thank you.

[@MrRctintin]

That was very clear thanks. Just learning G&M, and that was a great help to me.

[@saaimshaikh6815]

Thank u so much for this!I have an exam tomorrow and I don't have any notes.This video is a savior!

[@dunn-ng5878]

yes ! I start learning by myself from your video . this is the first lesson about code I learned. thanks

[@fr8tv4]

[@twosuns8704]

Very helpful,thank you very much.In one of my classes we are working on writing the programs for milling,we're starting with basic designs like your example part.I picked up on a lot of stuff that I wasn't getting in class lol.I took my time and paused every step to really understand each block.THANK YOU.

[@vergilalbia909]

very good!!!,,well explained g-codes and its functions..it helps a lot more people like me who just started to learn basic cnc-mill programing..thanks much for the brilliant mind and generousity of the person who uploaded this video!!!..god bless!!!

[@sk8guitardrums]

nice and very well explained.

[@cncprogramming3907]

Thank you for the comment!

[@jimjam1719]

yes, very well explained and methodical but at a very low volume, i had to crank it up to 80 or more to hear you.

[@tobiasmele]

Great video I thoroughly enjoyed every minute PLEASE do more!

[@meshalastic]

nice and very well explained. Big thanks, I wish teachers explain stuff the way you.

[@eric8027]

Awesome!!! Your explanations were spot on!!! Thank you for taking the time!!

Very nice!! I have just set up a 6040 CNC. This helped a lot

[@josecunha731]

Great job, excellent primer, very much appreciated.

[@dell051lt]

Wow, thank you soo much for this!! Definitely going to have my classmates watch this video. So,e of us were lost on trying to read g code. I am in school for this with a instructor who goes too fast during each lesson.

[@codymartin4771]

Thanks a lot this really helped me specially just starting to work with a Fadal Mill

[@joepie221]

Cody, On my Fadal mill, I can just use a G2 or G3 command and an r' value with an end point on radii under 90 degrees. Its much easier than the I and J line code.

[@darbo1067]

That was well done. Please make more!!! The only lines I need more info on would be block N5 and N15.

[@danieljusticiero]

Excelente, muchas gracias, esta muy bien explicado. Now I am a follower!!

Funny I took a 6 months worth of CNC study and this showed me exactly what it took a while 6 months for me to understand

[@Imbuiltlikethat]

This was really good

[@robertallnutt3717]

Thank you for excellent tutorial

[@billkellogg1403]

Excellent!! How disappointed when I found it was your only video!!

[@Sheikmaney]

Wow this was very useful thanks 🙏!!!!

[@anommouse1609]

i just made a coding sytem like a message coding but i was looking up g-eazy and hit gc by accident and saw this way above my knowledge never herd of it so.. thanks ig

[@stucapco9111]

Always nice to see a simple explanation broken down. Well done. Wait, it gets much worse. Preparatory and misalliance code groups can be nested. Good solid start here. Loose the line numbering and redundant modal calls. We're going to get this bad boy down to size. Nice clean explanation however. I liked it. I learned G-code out of manuals the size of telephone books. Well done!

[@Raptorman0909]

Very nicely done -- thanks..

[@PROBERevealer]

If you still there ! hope you would make more VIDEOS like that. God Bless

[@victorinborsciov6817]

Helpful indeed.Thumbs up! Don't let this video be "One time wonder"

[@josephp.polnaszek9134]

I like this video and wish you would put together more of them. How about; Peck drilling, Bolt circles, Profile milling, Single point threading in the knee mill. Thanks and keep them coming. Joe
