• CNC Build Part 1: Cont...
I walk you guys through how I build my base and linear rails for my new CNC machine from raw materials. It's not that difficult as long as you have patience, and a plan!
I like the approach of using common non-precision materials to make a precision machine. A man after my heart!
He can now CNC parts to make this machine more precise.
@@rsz90182 indeed
One recommendation I have from building something similar. Sand the steel smooth where the bearings ride, it helps a lot. The steel is rough. Once I sanded it got much smoother and quieter. Cool build though
Sanding would help. The steel has mill scale on it. It's pretty hard stuff and rough. it is difficult to sand. Just clean the scale off in a bath of muriatic acid and the scale dissolves, leaving smooth, clean steel behind. Only takes a few minutes in the acid.
I cant thank you enough for taking the time to make and post this series.
Thanks for watching! I sincerely hope it helps!
11:13 That moment of clarity lol "It should be pretty good man~ :)". Great build ideas. Im looking forward to the next videos. Thankyou!
I'm a machinist and I love this series. I can't wait to build
Glad to hear it man! You could pick it apart if you wanted to, lol. Thanks for watching, good luck on your build!
Tip from a skateboarder. To break the bearings in before using them, use an old desk fan, pull the blade off and put the bearings on the spindle. I wrapped my bearings in paper then again in duct tape and ran the tape to the desk to hold it in place, turn the fan on low to medium and keep an eye on the heat of the bearings, lubricate as needed. I'd let mine go like that for about a day, take em off and enjoy.
Awesome that thing is a beast!!!
this is cool to see someone doing a build on the cheap but making a good cnc
.3mm depth sag is noticeable when I use engraving bits (20 degree). But you can put paper shims on the table under the workpiece. Great machine! Subscribed and rang the bell!
No need to continue to qualify each step. We are in!
Hey thanks for sharing Ideas looks owesome and lo w cost just refining my Ideas to built one
Love your videos. Keep them coming. Hoping to see your subscriber #s skyrocket.
Phil Lemke Thanks man! I appreciate it! Things are going pretty well, I think it just may happen with a little luck and persistence. Thanks for watching!
This might be weird but it gives more possibilities than a standard cnc, 3d printer syled cnc
Perfect , so nice , well done man
asghar rezaei Thanks brother. It turned out pretty good for a cheap little machine.
this is what i was looking for, because i didn't find the right supply for any type of LR if i found the rod i got problem to find its linear bearing, also for other type of linear systems and deals also isn't fair .
Maybe shim the 90deg ends to fill up the loose play instead of doing dual motors. Love your videos and budget builds, they've got me digging for more info and building materials-lists.
FantasticMrFish I don't actually have to shim them because the y axis rails aren't bolted down yet, so I can set the distance there. I tried to get rid of the slop so bad on my other CNC, and it's just too easy to put another motor on. Plus the kit came with 4 motors and drivers, win win.
Thanks man, I try to keep my content and my builds interesting. I'm going to be posting at least once a week on my CNC progress, until it's boating weather anyway. Thanks for watching!
HA! Glad to see someone actually do this, I have been toying with this idea for a while now, I intend to use car windshield gearboxes/motors to run the rails, recycled of course haha
Yeah I love builds like that! Gotta be cost effective!
Only reason I went with the electronics setup I did is it was pretty cheap to buy the whole kit, and everything is purpose built to work together.
@@StrangeGarage Oh yeah, pretty solid strategy, I just happen to be good friends with a junkyard owner. I like to see how low I can get the project cost on stuff like this haha
I used angle iron for my linear rails. I had a different technique. I made a skate which attached to my grinder which allowed me to make to 45degree angles on one edge. This because my v rail. Google mechmate linear rails skate for a better idea. Thanks for this video
Dude you are good
Exlent sir.genius.
use some muriatic acid to remove the mill scale and then oil to prevent rust. The steel will have a better tolerance and run smoother.
Aloha Sir,
Very cool!
Mahalo,
Maverick Mike.
Nice 🙂
Nice way to resolve things. You are more engineer than some of my colleges
Thanks man, I'm an amateur engineer I guess, lol.
Nice build... maybe clean up that angle iron...it’s probably why it riding rough.
I do like your build. Minus taping with a drill can u. Post plans /specs. Somehow been looking to getting in to cnc but wanted to make a cheep one before I invest more into it
Is it also locked for upside or just Locked by its Waight and Gravity !?
Your videos are excellent, especially showing critical areas & pieces. Just 1 question but only because I can - Q. Is there any reason I could not mig weld my table & gantry or did ya'll use screws, nuts & bolts, etc because that's what most people have available to them? I ask because (for me) mig welding it all would be dead simple & ensure nothing ever loosens up. I will add tho, I'm thinking mig as stick or gas welding (I have all 3) profuces the least amount of heat & thus no warping of the steel.
Again, TY so much for your time & efforts in making this excellent series! Couldn't ask for anyone to make building a cnc any easier.
I appreciate your views my friend, I do all this for the interaction with you guys.
Great question: I excluded welding from this build for 2 reasons. 1 being that most people don't have welders (which they should if they plan on having a CNC machine). I knew If people saw me weld this thing up a lot of people would stop watching because they don't have a welder. 2, I wanted to mitigate warping down to the most finite level.
I also LOVE that I can make adjustments. If something is off I left myself plenty of chances to adjust everything. If I feel confident in my alignment at some point, I can zap a TIG fuze and make it permanent.
Alright this is what I wanted to see! cool... next... this is the terminator cnc 5000
Is it possible for you to share dimensions fir the frame, it might help me for my final year project. I will be thankful for this.
If you're going to make it stronger you should put a gear cogging
U should put a piece of all thread on the bottom of the trolley from one side to the other would hold tension on the inside bearings so u would only need 1 drive motor on that axis
I tried that on my last CNC machine, it really didn't work. The gantry would rack side to side, totally killing accuracy!
@@StrangeGarage I just started watching the playlist on this build looks pretty cool. I wouldn't mind building 1 myself some day
Thanks for the next video in the series man. You continue to amaze me with your skill base and presentation skills.
Here's what I garnered from your build relative to materials and some questions. 3/16 plate cut to dimensions 30 X 18 for your machine base. 6mm ID / .67in (17mm) OD hobby bearings. Are the bearings 606zz? What are the size dimensions for the angle you used, is it .12 thickness x 1.5 and lengths of the sections that ride on the rail? The screws and bolts are easily figured out and your sketch is very helpful. Thanks again man, This is going to be an awesome CNC machine I am certain.
Ted H Ted H oh, don't give me too much credit. Don't want me to get too cocky.
Great questions: the angle profile you nailed, 1.5" X .12 wall, the length of the carriages is 6". I went with these dimensions so that the final "functional" workspace would be 12" X 24", so 18 X 30" works out to accommodate that.
I kept all of the hardware the same (except on the carrige) for convenience, they're 8-32 X 1/2" CS FH.
I'm excited about this too, this thing is already pretty sweet!
Thanks SG, Just wish we lived closer to one another as I would love to meet you and go out for a beer on me.
I am going to start sourcing materials and build mine per your design as I am a total novice at CNC.
Are these the main screws? www.homedepot.com/p/Everbilt-8-32-x-1-2-in-Zinc-Plated-Flat-Head-Phillips-Drive-Machine-Screw-8-Pieces-803751/204274665
Ted H We're lucky we have the internet man, we never would have heard of each other at all without that.
Those are the exact screws. I would reccommend, however, that you hang tight for the machine to progress before you start buying stuff. I want to make sure you like the design and the capabilities.
I could not agree more my friend. I certainly will heed your advice however, completely trust in your abilities to build a quality CNC machine, especially given your experience having built one already. It's only human nature to learn as we go along and most of the time we get better with experience. For me, this makes life exciting and greatly contributes to the success of my business.
Patience is a virtue I need practice at so no hurry at all from me man. I currently have a lot of irons in the fire and spring turkey hunting and fishing seasons are right around the corner.
Ted H Man, you just wrote the preface to the book of my life! My last machine was built with NO plan. This new one is actually coming together FASTER than the last one, and I'm filming the whole time, that's how important having a plan is! Also the plan is making it a 100% better machine!
Man, I'm in the same boat. My wife is hinting that she wants to go out on the boat next week, and I'm trying to get some CNC stuff done, so I feel ya on the busy department!
Hey SGM, what is the best way to align the bearings? Thank you for the video! I love the thrifty build.
Bruce Williams That depends on what kind of alignment you're asking about. The way I get them to grab the rail tight is I loosen up one top bearing, put it on the rail, and shove a wooden shim between the carriage and the bearing, then tighten the bolt back down.
I hope that's what you were asking, if I'm wrong just correct me and I'll try again:)
Thanks, that make sense. So there is some adjustment to make up for any errors. It looks "skookim".
By the way, looked at your about and it said you are a tailor, that's cool.
Bruce Williams Yes, always leave yourself a way out! I make the holes about .020" oversize specifically for adjustment! But you can do that at any time.
Bruce Williams Lol, nah, my name is Taylor. The "job" that I do varies from day to day, but I've done many different things for many different institutions.
how do you go about the rusting of the bearings?
Rusting? I'm afraid I don't understand the question.
I have a question. Where do you get your CAM software? Is it expensive? Sorry if you covered it already on a different video, I didnt go through them all yet.
No worries. Fusion 360 has built in cam. So you can build your 3D model and generate g code in the same software. Fusion can be downloaded from the Autodesk website.
@@StrangeGarage I'm about to go through your vids right now looking for hardware for the build. Would you recommend a different cnc package (motor, circuit board, etc)? It was a package right? Happen to have a link? Fusion 360 come with the package? Thanks man.
@@justingodin7806 Honestly the kit was pretty good. I'm sure you can dump buckets of cash on a better kit, but for the money I'm completely happy.
Fusion 360 is free for beginners/start ups. Literally anyone can download it from the Autodesk website.
what bearing did you use 606z?
Yessir.
Hey Strange. :)
Ford's Tool Reviews What's up man. Good to see ya.
What is the cost of this machine..?
About $500. The cutting tool is another story. Routers are cheap, but I purchased a 3 HP spindle with a VFD, which is better than a router but also $300 by itself.
Perfect....it would be grateful if you share some plans or 3d model for it.
Thanks

Pains me to watch u tap with the drill
Never broke it. With the chuck set right and the appropriate hole size it's hard to go wrong.
Sorry, I meant the "with the clutch set right".
All the machinists out there moaning and groaning over less than a quarter mm / ten thousandths of an inch. We are hobbyists and don't need that level of precision for most projects. If we did we would probably have the money to spend thousands of dollars on a high precision machine. Most of us are just looking to get by without having to pay someone ridiculous amounts of money. Maybe that's why they complain so much. They feel like we are taking money from them?
Talk less do more
But for THIS amount of money 🤣🤣🤣🤣🤌
