"Stupid Strong" CNC Build - PART 4 - THE ELECTRONICS
HTML-код
- Опубликовано: 21 дек 2017
- How to build a DIY CNC machine completely from scratch. I designed the machine in Fusion 360 from the ground up and had a local water jet cut the parts.
The frame is built from 1/2" aluminum plate. Fully supported linear rails reduce the flex and NEMA 23 stepper motors drive the anti-backlash ball screws for the best possible performance on a budget. I used a TinyG motor controller in this project.
In this episode I work on the electronics including the stepper motors, Chilipeppr, and the Tiny G.

If you want to skip the programming part, the first cut starts at 9:15
Thank you SO much for this video! I cannot tell you how much this has saved me on my own TinyG build. The Chili Pepper code instructions you gave were extremely easy to follow, and there is no way I could have set up my machine without them!
Dude…. I totally dig your style! Ive watched atleast a thousand DIY CNC project vids, and this is in my top 10 for sure!
Curious to know how your backstory, and how you first became interested in diy CNC….
My back story is crazy lol !!!
For decades, Ive been a pro musician / song writer-producer but always took an interest in tech / engineering… Now I have my recording studio equipment covered in dust blankets, and have a room full of 8020, motors, controllers and cables everywhere! LOL! Not sure how I got here! Hmmm
Cheers!
Honestly it’s not that confusing when you watch this video a second time it’s actually pretty clear thank you for this video 😁
Great job1
1:23 - L = live
1:46 - You were Lucky, some of those anti-Static bags are conductive!
I have said at loud the same thing as you :D :D
"Most" of those anti static bags are conductive 🤣! I have never seen anyone use one as a work mat before 😬
Amazing job! Well done!
Great job Mike!
oooo very cool machine, great job!!
Was waiting for this vid🙂
Chilipeppr is an amazing tool for CNC! The guy who created it, John Lauer, helped me set my first CNC router up and is possibly the reason I now have a RUclips channel. He asked me to post a video once I had the CNC cutting wood and that is the first video I ever uploaded. I agree with you that the information floating around the web for the TinyG is such a mess, but once you get it figured out it's not too bad!
That's amazing!!. Thanks for supporting the community!
Beautiful one! What experience of aluminium plate tabletop? Im in decision about plate like you or T-slot.
if you finetune your steps per mm for x and y, do it with a piece as close to full bed size to minimize tolerance errors. Maybe even cut three pieces and calculate the average size drift. Nice Job.
You can also find all those settings by clicking the little gear on the right side of the page , a few icons to the right of the red feedhold button i believe.. instead of typing in the code settings.
For power, instead of bulk cable and a plug, consider an extension cord and cut off whichever end you don't need. Typically easier and cheaper.
I would like to see more of the financial planning videos. Also, is Lauren having the baby in the states or back in Costa Rica? Would love to see more of those type of videos!
Assuming you confirm that the machine itself is square by checking diagonals, you can adjust the number of steps in the drivers to get to a perfect 50*50mm. Great job so far
Purchasing a 345 Block will give you a perfect surface to test part size and the squareness of things in general to test against.
Thanks!
good job bro
Instead of wiring a plug, the home stores sell appliance repair cables. They've a plug on one end and bare wire on the other.
GRBL has fewer features (limited to 3-axis, no built-in web server), but is significantly easier to setup, configure, use and the documentation easier to follow. It also has dozens of open source software options for controlling it, none of which require a separate JSON server. Something to look if you want a toolchain that can be explained to normal humans. Full disclosure, I develop Universal Gcode Sender which runs GRBL controller boards.
3 cheers for GRBL, been running it for a couple (or more) years now. But I do not use UGS. The last time I looked, it didn't have features that I wanted, which is built in probe functions. This is invaluable for me as I use my router for (almost) nothing but isolation routing of PCBs. So I've been using bCNC. I'll go take a look at UGS again to see what has been updated recently though.
Ian Ide the UGS nightly platform build now has a probe module if you want to give it a try. I try not to push my software too much, there are lots of great GRBL interface options.
Does UGS run well with Debian? Well I spose I can find out, it is java based after all.
Hmm, I might have a look through the source (if it's available) and add some buttons to it. Being the creature of habit that I am, I probably wont bother. I have a feeling that I'll start digging into it and find out that the layout was done in some platform that I don't have installed which will make things just that much more bothersome.
I have been known to be lazy when it comes to editing some one else's projects.
Edit: yep Netbeans and Mavin.. I definitely wont bother, heh
Why is it so difficult to download UGS? I keep trying but never get something I can actually run on my pc.
hi Mike. good lessons so far. saw your vids. but what about seperate motor drivers like DM556 (to run NEMA 23, 4 amps)with mach 3 breakout board? or have you tested on Carbide3D or Vectric? What if in case of belt drive (3 mm pitch 3M HTD 15 mm belt & 16 tooth timing pulley),. Why I am putting the questions....? you know ?
I have been trying to build a 4 x 2 ft machine which will have a Makita spindle and Two simlantaneous Y motor, belt drive, except Z (with ballscrew) on secured V- rail. Can you guide me on software. I am having no previous CAM experience. I have a vinyl cutter that runs through Flexisign v8 software, that much I know. Strongly, I feel the need of plug and play type software.
Hobbyist like me have lot of troubles in synchronization with some particular software. I am also very new to Mach 3- a very messy interface. I have seen Carbide motion is clear enough, but not tested. I also have seen Vectric aspire, But the fact is the design and CAM-ing shall be on same platform. Just like converting any image into 3D paths and CAM starts on a "go" button. easier said than Done! But no Linux please. If you have little time in hand, then show me the way....
what would it take to cut 7075 aluminum??
Pretty good name for a cnc machine)
Sir please give name witch bod do you use
You should plane the waste board and set it as the z min
How close us your workshop to your house?
If it's under 30km with line if sight at a reasonable antenna height, you should consider seeing up a Ubiquiti link (really reasonably priced, no licensing) between the two. You can have internet access at the second location without an additional monthly fee. It would also make an awesome video.
I have two Ubiquiti access points that I've been dying to setup (actually, I have 3, two 5Ghz and and 2.4GHz for connecting to a network I can't hard wire into), but can't build the antenna until I move as we currently rent.
BTW- This video series is pretty neat, keep up the good work
I know this is an old post, but I too have used tons of Ubiquiti, such a great product for wireless point-to-point shots. It is how I get wireless to my garage.
Can you give the FULL specs of the power supply that you used, not just the Volts. Like Input Volts & Amps and Output Volts & Amps
What i dont understand is why other projects motor drivers are huge and they need a huge enclosure box for the electronics. Also they have different voltages for different things. Its so confusing. Is this build strong enough electronic wise?
I've moved from a mach3 parallel setup to grbl but I regret it now i know I can't get the accuracy I want using grbl
Very cool and, I wanna start my OWN machine but,alas, I better fix my car's brakes first. :-(
With right turn spindle you should mill in the other direction.
Good to know, thanks.
And climb cutting leaves a better finish =)
But you need to have a strong, stable machine. Climb mill is better but not for diy router.
It isn't strong. Dial indicator gauge will tell you the truth.
the amazing power of free software. no I'm not being facetious. Amazing. bad documentation, sure, but I remember how terrible linux documentation was 10 years ago.
What you remember is different than my recollection of things. But 10 years ago I already had 12 years of Linux experience, so that probably colored my view of things somewhat.
10:45 dont change nothing you have all correct. lead is 5mm. it just cutting forces and bend. change tool diameter offset or drawing if something and if axis not alignment then it show on part.100% sure z axis not aligment
I want to see all the potholes and dead ends.
ground neutral and live*
Try line, not live. If you are going to correct someone try to be right next time.
At first minutes i think i understand..after minute i sleep..
I would not suggest keeping circuit boards of any kind on their static bags, the static from static bags is on the outside so it could cross to solders, just saying ruining electronics sucks
Is there a way to not watch a 5 minute advert before your video starts?
I don't understand why you made the work area so small, I know you made it bigger it would've cost more but if you're going to build your own CNC machine you should make it have a decently large work area.
I built this to fit on the 24” work bench in the mobile workshop. Intentionally compact. Making it triple the size would only cost 10-15% more.
don't put the circuit board on that mitalic-y plastic bag! why do people keep doing that, the outside of it is just conductive enough to ruin your board
Weren't you penguin from Batman 2?
