This project wouldn't have been possible without the help, patience, and mentorship of my employer @macgyvermodels. Big ups to Simon for giving me the opportunity to do what I love. - วิทยาศาสตร์และเทคโนโลยี
Damn, I'm late to the party because I forgot to hit the bell.
Everyone learn from this guy 🤌
@@NoEngineerHere we must learn from the best engineer that isnt an engineer , or so he claims
same haha
Bro wozit ..I love the idea of jack screws. ... I have never seen it before 🎉🎉
@@NoEngineerHerewhich one oil use to spray on this job ?
Will you please tell me the name of this product
OK I'm hooked. To the moon, my friend!
To the moon! So glad to see you here 🙏
"There might be a few small changes to my approach the next time around. For example, I might spend a little bit more time just buying a machine from an existing manufacturer." LMAO
Hahaha yeah, this applies to every major project I've ever done. "WHAT!? $XXXX for one? Screw that, I reckon I can build my own!" *6+ months of pain later* "well, sure would have been cheaper and easier and better to just to buy one of these..."
I am an engineer and I don't think I could pull this off. Awesome project!
Same here, i would spend five years planning every small detail, then decide on the least terrible design whithin the budget and get frustrated half way into the build :D
@@peterpan6406 yep me too!
I'm not an engineer and I could pull this off with at least 10 times worse results
Most of the times i just start a project with a general idea and figure it out on the way.
I’m sure you could overdesign the shit out of it though
Nothing makes you want to buy a CNC more than watching what it takes to assemble your own or actually doing it yourself.
"Let's make some chips!"....Straight out of the TOT playbook 😁
Cheers
Mate, I’m an engineer and I have to say..there’s more capability in 2 videos than what they teach at the cookie-cutter, factory-style engineering degrees they pump out these days
Well done.
I look forward to more videos
That potato though xD
Great build, great humor, can't wait to see more!
Had a lot of fun with the fixturing on that. Thank you!
@@NoEngineerHere But did you cook the first chips?
@@bitp1mp I was hoping he would show up in the next scene or something eating the chips but it never came 😭🤣
Man really went from less than 600 subs to 25k in less than two weeks.
Cheers mate, you deserve it.
Came here from that other Aussie with the apron.. You're basically the down under version of This Old Tony.. Keep the honest projects coming!
This is great, your channel is going to blow up if you keep putting content out like this. Any reason you used the oil/sand mix vs. epoxy granite?
Thanks mate!
Mostly transportability; if I ever have to move I can empty the sections out to lose the extra weight. Once I get a more permanent workshop (or a forklift of my own) I'll definitely go with something more solid!
@@NoEngineerHere That makes a lot of sense! Adam Bender has a great epoxy granite mix video with store-bought stuff - for your future reference! Can't wait to see more - I definitely vote to make upgrade parts with the CNC!
@@NoEngineerHere Over the last two weeks since you posted your first video I've been doing a deep dive on every hand made DIY lathe and mill on youtube. I also had thought of using sand & oil or ball bearings & oil for a similar reason of being able to break it down for portability if needed. I can't wait to see what your new spindle solution looks like! Great work.
@@NoEngineerHere You should do a video about ruining a video by adding music. Never mind you just did.
This video was great and the music was a nice addition. No need to be a downer for no reason
Absolutely loved both your videos so far. Excited to see what’s next!
Hey thanks man! Me too 😁
Channels like this give people confidence in doing things out of the ordinary & excel them into doing things they never would’ve dreamt of doing, thanks for sharing 🙏
The mill looks great. In the machining clips the motion of your machine is dwelling at the end of every segment in the program. This is either a setting or some kind of servo dynamics that may be causing this. On the square and hex it is understandable to slow down on the corners but it was also doing this on the circular milling as well. As a person who has watched many, many hours of different machines running this looked a little disconcerting to me. The motion should be smooth even at high feed rates. This could also have to do with the unusual surface finish. I don't think it is the ball screws that are causing that finish. Backlash shows as a definite line in circles but not on prismatic shapes. Your measured relatively accurate sizes. So I think there is something in the servo setup that causing that and the dwelling in the motion of the machine. Just a observation, otherwise it's really working good. Maybe you could look at the spindles like Stefan Gotteswinter put on his new mill. The one he is using can also change the tool.
It could be down to the controller, I'm just using grblhal on a teensy 4.1 at the moment, will be upgrading to something a bit more professional grade at some point soon - mostly for ATC support, but also simple things like a run-from-line function. Thanks for the info! :-)
@@NoEngineerHere We have a '90s mazak mill that has similar troubles and that is caused by the machines own computer just not being fast enough to read what a modern computer sends it, so yours is most likely a baud rate/ data flow of a controller just not being fast enough to send ahead data it's getting
@@KittyCatInAMicrowave the same thing happens in the world of 3d printing... when you have your feedrates set so high the controller can't put out the necessary bytes of calculation per second you get jerky uneven motion. This can actually be calculated. Sometimes the software is also manually limited to a certain number of commands per second. Both worth looking into.
@@NoEngineerHere Hello NEH, Terrific build!! I built a 3m by 1.4m cnc router and your detailing in getting the axis's right is on another level. I was using one of the Mach3 controllers but went over to UCCNC, the difference in machining quality ( even in wood ) was astounding, very easy to setup, has more capability than I can use and isn't that dear.
@@skillenmcnotI was about to say this! Encountered the problem many times back when printer controller boards were still basically Arduinos on breakout boards :)
I went through the same process in 2018, a smaller scale and without even trying to film it and document it as you did. You, sir have my respects, that's an awesome DIY CNC machine you got there, enjoy it!
It's rare to see the build skills being at least equalled by the video editing, music and humour - well done! Looking forward to more content.
Great project! Just wanted to say there's black sand that is 2x heavier than normal sand. It's the same black sand that consists of hematite/magnetite that gives gold prospectors a headache. Normal sand has a SpGr of 2.26, and black sand >5.20! That stuff is heavy!
Brilliant build and great story telling! You asked for opinions on your next step... I'm in the middle of my own build, and when I reach this stage, the plan is to add some bits and bobs to make the machine more productive, like an ATC, and 4th and 5th axis.
Great minds
love everything. the squiggly text, pace of the scene cuts, the humor. i cant wait for more :D
I’m just finishing up a similiar build, but its been a year in the making. I had many similar learnings, like upgrading the spindle. I settled on using an AC servo. I too used jacking screws on the base of the column but I like the idea of the epoxy. People always ask me what I’m going to use it for and now I’m going to tell them “to make chips”. I think I’ll use stainless steel screws however to hold the stock 😂.
Nice one! I could give you some little hints: make an external plexiglass housing will reduce the noise and keep yourself alive, then you can make dual spindle mill, one slow for steel and another for aluminium, try single flute bit on aluminium and always choose 7075 as aluminium, you'll never regret, bye bro
Spindles like that (22kRPM 2-pole, I presume) are usually designed for woodworking, or smaller diameter tooling. If you start using larger bits (>6mm) to gain rigidity/accuracy, you may want a slower speed, 4-pole spindle. You can run high-speed spindles at lower speed via VFD settings but you will lose torque.
Yeah they really don't like going under 10k or so
always here for some self depreciating aussie content. amazing work, with an eye for esthetics as well.
Thanks for bringing us all along with this project!
That sure is a beauti. Well done on the new machine you did a fantastic job. You want to either sell the plans or sell a product you make on it for your subscribers to purchase and fund future projects. Cheers J
Thanks man! Intending to keep it pro bono for a little bit, but there are things in the pipeline!
What a beautiful hunk of a machine! Honestly, I'm amazed you managed to put together something this precise and still make it entertaining as well!
Absolutely mad! My utmost respect for your work and effort!
the quality of your production is astoundingly accomplished. both the video itself and your cnc!
That was really impressive! Awesome build!
That is NOT how you use a micrometer though! I was taught to use the small knob at the end to tighten until it clicks.
Nice.
In regards to the ballscrews, you should be able to remove backlash by having two nuts on them, and then adjust the distance between them to take up the backlash.
Fantastic another aussie machinist to add to my collection
I look forward to more videos from you!
Looking forward to upgrades for sure
Excellent video! The quality of these are really good; the editing, the sound quality, the humor, and especially the build itself. It's hard to believe that these were your first videos.
I'm looking forward to more videos, and seeing how you go about upgrading the mill.
Definitely look into liquid cooling for when you start going at the harder steels too, hopefully that'll keep you from breaking too many end mills.
Rad! So stoked that this series continues! I feel like an enclosure would be a massive quality of life improvement for ya. Also really curious as to what your goals are for the cnc, are you wanting to do production runs of products? One off projects? Big/small things? Useful or goofy stuff? Anywho love where you are going with this and can't wait to see where you go with it!
nah, gut to have a cnc to flex on woman......they really care about this, trust me😂
IMPROVEMENTS!!! my favorite part of any project. I am so glad I found your last video
Brilliant project! I look forward to your upgrades!
Besides all the good stuff, nice tunes going on, mate! Classy stuff!
Love it you have a good sense of humor and nice attention to detail.
I love this channel
Brilliant! Love the build. Looking forward to more content.
LOVE your dry presentation - honestly refreshing
This is an excellent video, you should feel proud of your accomplishment. I look forward to future projects.
I am an engineer (retired) with some machine tool experience (1970s). I enjoyed your presentation and your self deprecating delivery. Keep it up!
@NoEngineerHere Similar to others mentioning about the odd dwell pausing as the machine gets to corners. Like they said its just the sheer amount of G-Code that the teensy is trying to digest.
One of the biggest helps I've found for this is by changing the settings of whatever program your using to generate the toolpaths to output arc (G02 and G03) moves that use I and J terms instead of using linear moves on arcs.
Many programs and post-processors default to using linear moves even if you're actually wanting to move in an arc, so they fit hundreds of tiny linear moves to try and 'describe' an arc or a circle instead (resulting in literally hundreds of lines of code) rather than using two arc moves that takes only two lines to describe a circle!
Not only does using arc moves speed up your CNC movement by reducing the code throughput (if that was a limitation), but you also get better surface finishes on curves since they are now made up of arc's rather than lines (the accuracy of those linear moves can be adjusted upwards but that just means MORE code and even slower machine movement).
Please ignore if you're already using arc moves but hopefully this might help.
That's a BEAUTIFUL machine by the way and you should be immensely proud!
You are inspiring me to pick up my conversion project again....At least I located the once forgotten pieces. Awesome machine! 👍😁
This is incredible! I wish you spent more time on the build. Also the motors and programming.
I can't wait to see the new spindle
Mate, your channel is bound to blow up. Excellent quality and personality.
Nice work.
Great build.
Thanks for sharing.
This is a massive inspiration for me. I am an engineer, and I find machining absolutely fascinating. Maybe I’ll try to pull this off one day….
Ive built my own cnc mill.. Its concrete and steel with a 1.5kw spindle gear reduced to 8000 rpm . While I learned a lot and its super rigid , Ive never gotten the accuracy of an out the box tormach or mr1 cnc. Well done on your project.
Thank you for showing you indicating the part to the spindle. Not a lot of people I’ve seen would show that but indicating is such an important part of machining.
Great couple of videos, the machine looks amazing! Can't wait for what's coming next.
That's really good You should be very proud, getting consistent 1/1000th of an inch accuracy is great, take the W bro bro
Love your video style and editing. Great job!
man why your first two videos feels like you've been a youtuber all your life ?
Maybe I was born this way
Now all you need is power and accuracy. Lovely build. Always jealous.
You are a legend and a scholar, truly inspirational!
That's awesome! Between when I was training to be a welder and when I decided to learn game development, I wanted to get into Mechatronics, so this is right up my alley!
Absolute banger of a video. Looking forward to the next one!
TH-cam has been trying to convince me for a couple months to watch your videos. Glad I finally mustered the courage, great content sir. I had to pause to laugh at the chips joke for about 30 seconds. 🤣 Cheers, keep it up.
Phenomenal, mate. Absolutely love them
Really glad to see taking time making table and axis both parallel and co-planar. Lot of DIY videos skip the co-planar step at least on camera they do.
This is amazing. Great job
Amazing job, congratulations
You don't learn a lot by buying. Great job!
Love your videos so far! Keep it up!
Your humour is top tier - also good to see a fellow aussie working on this type of project
This channel is a riot. Thanks for the videos.
Dunno much about CNCs but the narration…..spot-weld-on!
That's the language i undestand by far! Great content with an unique combination of flavours. Congratulations!
I work at a shop that builds these... a different style but many of the same parts, bearings, rails, ball screw etc.... super impressed w your work! Great vids
At 1:10 I was waiting for the “bell end” sign to switch to him, lol
I look forward to your next video, your content is fantastic
Nice. I exactly know the feeling of spending my last money which I don't have, on a totally unnecessary project wchich I can live without. And in the end, the better and cheaper solution is already there to buy, and I knew about it in the beginning. Approved.
Mate the thought of having a project to just get stuck into for 6 months straight, and loving it as well, is a fken dream
Life was simpler then
@@NoEngineerHere hopefully it was fun and not annoying as fuck haha
super impressive build. also super impressive video quality from a guy with only 2 published videos ! keep it up
Amazing work!! Love the deadpan humour.
Excelent job! Keep going!
man you really got a crazy fucking skillset. I wouldnt be able to build something like this in a lifetime
I love this, brand new channel with promising ideas with a "I will post several high quality, interesting videos for a couple of months, disappear for about two years without any notices whatsoever, then post a video without any explanation of what happened" type of vibe, I am excited to see what is coming!
You've made a great build with your first DIY CNC. The surface finish is decent, especially considering you've yet to tune the acceleration/deceleration and speeds/feeds. That said, I sincerely hope your better half is more understanding than mine.
It has taken years for my wife to finally see some value in the "money you've [I've] wasted on tools for your [my] shop." It's only because she realized I could make items that "Jeep people" would purchase at inflated prices.
Of course, she does have a valid point. While I purchase computers, machinery, and cutting tools that I use frequently, I also buy some that I *might* use someday. My theory is that it's better to have it and not need it than to need it and not have it.
It was a bit of a sore spot while I was building it, but seeing how well it's done here, she's coming around 😅 I think her tolerance might be too high now though, I can't go unchecked for too long....
YOU'RE GREAT MATE! Great music, machine, production, chat, etc.
Keen for your next video from another Melburnian
Congrats! Great work!
impressive build. i love it !!
Epic build and your sanity survived intact, relatively speaking and remember that normal is a cycle on a washing machine...
congrats compared to other peoples take on diy cnc mill this si the best one Ive seen
The humor is the right amount of sarcasm that belongs woth these types of projects!!! Love your videos, you're about to be the biggest DIY channel i can feel it!
Im running that same spindle with 4mm end mill, in alum at 9500rpm. 1300mm/min Adaptive clearing, 1.2mm chipload. Works well, isnt too loud.
It's a monster, a very precise one at that.
I love it when a plan comes together.
Damn, you've done a 1000% improvement from your first vid. Holy shit bruz you gonna be a youtube star!
Great video! And yes we want more. :)
Hi a simple upgrade to your machine would be to change all the balls in your linear rail slides to ceramic. I have found the the steel balls, even is the more expensive ones are not round. Quick way to check just place a few balls on a flat surface. An additional benefit ceramic ones no lubrication is required. Also you may want to check speeds and feeds for the various bits that u are using. Manufacturers will have that information on their web page. Thank you for your videos.

Looks great! Do a little work on the motor tuning in the control (acceleration ramps) and you'll likely also see an improved surface finish. It looks like it was in exact stop mode, so it was trying to stop at every corner or arc termination, then slowly accelerating up to speed, slowing back down, and stopping again. For good surface finish a consistent feedrate is important, so increasing acceleration and reducing the stopping will give nicer cuts and run jobs much faster.
I wish I could get to starting literally any of the projects I want and even successfully finish at least one of them
Awesome video and an impressive machine
I do hope you covered one side of the column bed joint with a mold release in case you need to move the machine in the future.
I can easily see this becoming my new favorite channel.
