- NYC CNC did a good vid on the same topic, different application a few years ago: • Use Arduino to Control...
THANKS FOR POINTING OUT MY MISTAKE! "count less than or equal to pulseset" caused it to turn 2401 steps. You can see a little ridge in the part where it goes too far. Fixed by removing equal. "count less than pulseset"
Wiring connections
Arduino Pin 8 to stepper driver pulse +5V
Arduino Pin 9 to stepper driver direction +5V
Arduino Ground to stepper driver signal ground Pulse -ve, Dir -ve, enable -ve
Arduino +5 volts to on/off switch to stepper driver enable +5V
Helpful hints:
1. Pick the size of motor you need for the torque/power you need. Don't know? FIND OUT!
2. Determine the voltage and current of the stepper motor.
3. Determine the stepper motor driver that will power your stepper motor with some extra fudge factor (this stuff is cheap). Big Easy driver or Adafruit motor shield for small stuff. "CNC stepper driver" for big stuff.
4. Determine the power supply you need for the input power, voltage and current your stepper needs. Add extra fudge factor.
5. Get an Arduino. (Like you don't already have 3 of them kicking around).
6. Cut and Paste the code to the Arduino IDE; upload to Arduino.
7. Hook up wires per the diagram on the stepper driver box and the Arduino Sketch.
8. Hook up a switch from +5V from Arduino to the "enable" terminal of the stepper motor.
9. Hook up all 5V signal ground from the stepper driver (negative) to the arduino ground.
10. Set the stepper driver DIP switches for the max current, holding torque and steps per revolution you require.
11. Triple check your work. Cross your fingers and toes. Plug in the power and hit the "enable" switch.

Three videos in as many days, it's like a dream!! Keep up the good work!

Must be on a sabbatical :)
Anyone ask him why there are dicks drawn on the "computer" screens yet?
That's the watermark for an unregistered version of AveCad. It would be weird it if there wasn't a dick on it tbh
That's not as much of a curiosity as is the question "where are the vices??"
lol
To check for A and B wires, just touch them to each other (2 at a time). A- to A+ (or B to B) will put the brakes on the stepper motor when you turn it by hand. No meter needed...
Mat Helm or read the label on the stepper.
Your's still have labels? Wow, you must be rich..... ;p
The label says 红色和绿色是一对黄色和蓝色的b边对
Not really helpfull is it?
It has the color code on the motor..
4th line down on the motor label, colour codes in English
I really like how laid back but also honest you are. Feels like my dad explaining cnc to me. Love it.
Please do more of these educational videos. I like your tear downs but these are super duper helpful with your entertaining and no nonsense approach. I was struggling to wire one of these suckers up and you helped me understand it (and understand that the PWM signal from a beaglebone isn't powerful enough to trigger it)
Thanks for admitting mistakes and not giving up, its what makes this channel so great. Talent means nothing without persistence.
If you want an exact half a revolution, then your code needs some tweaking, as now it goes 2401 steps in your while loop, because 0 to 2400 are accepted conditions. If you start from zero, your compare has to be count < pulseset, so drop the equal sign.
I have no idea why I watch these because 99.999% goes right over my head, yet I never not watch. I love the way you take a problem and bust your nuts until you get it to work. Thanks for putting your work out there. Keep them coming, and I shall keep my penile appendage firmly entrenched in the metallic gripping device.
So many uploads in the last couple of days, awesome!
I have absolutely no use for the knowledge I absorb from these videos but they are so well done and interesting to watch. thank you!
gravylookout same!!!
gravylookout, I'm glad I'm not the only one. The lingo is worth watching the vidjeo.
You never know when something will be useful.
Nice Hitchhiker's Guide reference!
i love the approach of gradually getting up to a cnc like setup its like watching the evolution of mechanical engineering but whith all the gadgets that are currently available not a first there was this then someone added this timeline approach. as someone who loves to tinker but has limited time at home i love your channel as it gives me so many idea's and reduces the learning curve on so many projects the fact that the audrino can do so much at its price point just amazes me but with enough code and the right shield things can happen. keep up the great work
Dude, watching your video automagically has me compelled to expand my machinery like a gas. I've got to add a rotary axis to my kit. That will eventually become two, then ten. Your clips are boss!
aww waking up and seeing a new Ave Video #GoodSundays
MrJunkiePlay aww going to sleep on a Monday morning (1:00am) farking CHOOCH AvE flogging me with another video arggghhh
absolutely amazing :)
hehe :P well its now 3 pm hey nice sunday i would say
indeed lol

@@ryankimball6030 Hmm, pretty sure I was 20 during this comment, but sure! Hope you are enjoying grammar and mechanics class.
@@CProgrammer3088 that was a total accident. I butt-commented. Sorry.
@@ryankimball6030 in that case I apologise sir. Have a good one!
Just wanted to let you know that I have been enjoying the increased frequency of vidjos thank for the laughs in the shop
I love the direction you took this video. Some of my favorite content on your channel :-)
Congrats on 400K
That while loop will actually do 2401 iterations!
Yep, take away the = or start count at 1
yup, seeing "
This was fun video, love the hands on approach to seeing what the electro-pixie powered wonder twister does. What a useful little rig in a machine shop, there is a host of things you can use this for, like milling your own fastener head cutting to using the linear actuator to make a bottle decapper to open your beer.
That's awesome! I have been doing lots of research on using the Arduino for a simple, small milling table and ill tell you what... Iv learned more from watching your channel then most others. Keep it up brother!
You can go straight to G-code with CNC. No CAD. No CAM.
Look at grbl shield: which STILL won't drive the big steppers directly. But it looks like a simple CNC system, from 1 to 4 or more axes.
Doing it with less is fun and instructive, so even if you go for slightly more complexity, then you'll solve problems much faster.
Nice video.
With a little modification you could take that square stock and make it round stock and sell it and make a fortune
I think a lathe would be much better suited for that purpose; speed, cost and stock length abilities.
theomnipresent1 really?
@@theomnipresent1 No this would be much more efficient than a lathe.
Wow, thank you. I have a project in mind using powerful stepper motors and this vid gives me lots of the data I need.
Awesome video.
I've often thought I wanted to drive a large stepper motor but I had no idea how to do it. I still don't really have an idea but I feel slightly better about that.
Congrats on 400,000 Subs AvE :-)
The Satie music was very relaxing.
But also a pain to play haha
so many videos in the past few days!!!!! LOVING IT!!!
One of the best presentations of Ardo and Rasputin doin its thing I've seen on the 'net.
Hopefully some kids actually watch this, become curious and start doing stuff with it.
Seriously, really cool to see this kind of usage of basic computer chips and computer I/O code integrated into our basic machinist world.
Stick your pixie in a vice!
Hey +AvE. A small refactor to your Arduino code and you could specify rotation in degrees - might be easier to update when you come to edit your code down the line rather than having to remember 4800 steps = one revolution. Also, your while loop might have an off by one issue, counting from zero to less-than-or-equal-to (
Very detailed and well. Thank you.
It's cool watching you work through this. You're smart man.
The first 5 minutes of this video gave me flashbacks, to my struggles with the same type of stepper motors and drivers. I ended up in much the same spot. With a bit of chewing gum and bailing wire and a few automotive grade diodes you can tie multiple power supplies together in "cereal" to up your voltage on the cheap. I was only brave enough to go with 2 25V 15 A supplies. Great work, and a great video. Also nice computer graphic.
It ain't "big" until they have to upgrade the transformer for your street.
Yes, a home gamer can feel the need for 60kW.
Godfrey Poon i seen a dude setup a fab shop in his shed, all them welders and other stuff running
sounds like my cars stereo...
arnt loud till your running a higher out put alt from a different car you made work...like 4 batteries.......
can never have too much powaa
Sounds like something PhotonicInduction would do/need... :D
+Bainanaz Ah yeah, that's my scenario also.
A plasma cutter, big air compressor, carbon air arc gouging, etc, and then I made an induction furnace. I just wanted to cast some iron, you know.
Ain't no such thing as too much powah.
1.21 gigawatts.
Old toolmaker tip. If you mount your rotary axis parallel to the spindle axis, you can smooth out that surface finish, rigidity permitting.
Good to know! Thanks.
I've been fighting a DC motor circuit w/ feedback for a telescope mount forever. Finally chunked it and went with a geared nema17 stepper. Ain't looked back since. Love the little Uno's.
even if I have NO idea what you are talking about in those kind of videos were electronics are involved, I still enjoy watching them.
damn next video already? :D this channel is pretty skookum, chooching along nicely
This is an awesome build. Why didn't you mill with the rotary table axis vertical? I would expect a better surface because the bottom of an end mill doesn't cut flat, but the side does.
Sir, you are truly a pioneer. I love your content. Fabri-cobbling!
Great job getting it all to work! Thanks for sharing your experience
Spends minutes to check which wire is which, while it's right there on the label of the motor. Oh never change AvE!
likely does'nt trust those labels and need to see it for himself that they are correct. proby been down that path before where incorrectly labelled.
I have to say in his defense , I would have given up on the first line where it said A+(chineze font) A-(more chineze font).
plus im sure he is trying to teach us about steppers .. that's the point of the video ... aint it ?
Agree. Teaching us what's inside without a tear-down.
And not every stepper you find still has a label even if it left the factory with one.
@@forthereg The wire colors are clearly marked in simplified Chinese and English. 红/绿/黄/蓝 = Red/Green/Yellow/Blue that and 黑/白 (black/white) and maybe 棕/紫 (brown/purple) will get you a ways.
That is clearly Dr Evil's rocked on your hand-drawn computer monitor.
Unless rocket is a euphemism.....
This Old Tony is awesome. Glad to see he's getting a larger audience. I binge watch your vidjeos and his
You rock man-thanks I really dug the lay explanation of the coding and the void loop calculation/timings
"AvE creates CNC machine while vehemently denying it."
That's right, all you made was a Numeric Controller that runs off a Computer. NCC is not CNC at all ;)
He did there, eventually.
Finally it is ONC ordinateur numérique commande
not CNC
@@lpjunctionbéni-oui-oui
There no G code.... so he’s holding on to that.... or so he says lol
It seems like you're using a Computer (arduino), with Numeric input, to Control a milling machine ;)
Lets not call it a CNC though ;)
well done Chris, got up to 400000 subscribers . nice work man, hope to see this channel get to half a milion
Nice job,looks like a good setup for a automated tig welding lathe/positioner
Thanks for laying it out simple for us :)
My fiance gives me a massage while I watch, as she calls them, "skookum choocher" vidjayoes. So, thank you very much sir for this flurry of content.
quick question, where do you buy the bulk of your electronics from?
as in your bread boards, leads, aurduinos and that sort of stuff?
thanks
GoofyRiot He gets a lot of bits from adafruit, check out their YT channel,
Chinese fleabay is cheaper but sometimes the pixies fall out and the instructions are painful,
the beauty of adafruit is that they have simple instructions and a huge online community to help with the head scratching
Yep we have a WIN!! nice work!
Great Vijeo! I've been looking into microstepping for a project idea... this hit the spot!
Loving the Wyle E. Coyote schematics hahaha
God damnit, I need to get myself a mill and a lathe.
Nick I just started on this trail... I need to do questionable things to fund it...yolo?
Jeff Streak "yolo?" yeah, I'm a day trader too. /r/wallstreetbets
Depending on where you live and quantity/quality $500 for each shmoo deposit.
Nick, Good place to start is Taig. Mill or lathe. I have the CNC mill, does some great stuff. Can have a super setup for $2200ish.
Excellent video! The right amount of explanation and demonstration.
thanks dude. this is something I really wanted to see. I have been wanting to buy those wantai drivers for a while now. Again, thanks for showing us this.
Weren't you worried about throwing chips into the ICs and breadboard?
Did you run into any/what did you do about losing steps during operation?
so take it easy on the cuts or else you need to add error correction into the program? shit could get tricky fast.
AvE you must be proud. Awesome vijeo. Three (3) uses of HPHT. Awesome topics, machining, Arduino, electronics, C programming, fun, fun fun! And >400K subs. Learnt so much in a 27 minute YT.
Lol amazing vid. Very clear. I love the recap at the end.
Other pretty cool controller is "smoothieboard" way more capable, onboard stepped drives for reprap 3D printing or nema17 size steppers, but also has breakouts for pulse and direction to use external stepper drives without much more fuckery, also has Ethernet and can host its own website (eg pronterface for 3d printed control from web) I'm working on re-braining industrial embroidery machines with smoothie, some docs off smoothie site
I suppose if you need a reliable supply of hardware a case can be made for Smoothieboards, but most one off hardware hackers can get their mitts on a defunct PC that is at the same time more capable, and less expensive too. I know I have LinuxCNC running on a PC that I picked up for $5. It'll totally piss all over a shit stain Smoothieboard too.
Paul Frederick smoothieboard... that word I do not think it means what you think it means. A crapped out PC makes the G-code, it does not drive the steppers. You then need something with enough comms, pins and CPU to turn G-code back into stepper commands. And these days all the cool kids are 3d printing their own custom cases with temperature sensing pink to purple dicks sticking out of the top, so you can stick that dick in your vice whilst still retaining full mobility around your 'shop
JBFromOZ
I have 3 TB6600 stepper drives hooked up to a BOB I made. So that cost another $30. My whole CNC machine only cost twice what just a Smoothieboard does. Motors, drives, PC, frame, linear guides, actuators, spindle, all of it. Every nut, bolt, and screw!
that bridgeport mill just sounds like it's on deaths' door
his Bridgeport isn't in great shape but it's honestly not real bad. the horrible noises are likely from a lack of rigidity in the overall setup. rotory setup is clamped to the table, I don't think it has a brake, work is held in its chuck, etc etc. that all stacks up. thump thump on it with a big ass EM like that and it's gonna get the whole thing rattling around like crazy.
some things that help with that kind of thing (short of a stouter setup) smaller EM, more rpms, more consistent engagement, smaller cuts done faster.
Pretty sure the entire table has visible play in it
Another awesome video AvE. Keep up the good work!
Another incredibly inspiring video, learned a ton.
Now you just need a stepper to drive the knee and the table and you can enjoy your favorite libation while the machines make chips! Just try not to let them get sentient.
Whelan lol. Have you seen the jankiness? I say encourage it to become sentient.
What song is playing in this video?
Translate . . . .Why cant I hear the song. . . I'm catching on to this UT chatter, he didn't have his volume on , you tubers are so funny.. . .keep it up for the rest of us
You should at least recognise the death....sorry, I mean the wedding march. The other tune (piano piece) was Gymnopedie No1 by Erik Satie

I have an RSS feed on my blog and it picked up your video. What a gem of a find!
one of your best AvE, congrats on the 400k
Why is it i've never seen AvE and This old Tony in the same room?
Some things, if you get them too close together, they will explode...
thank God for smart people because this stuff is way beyond my comprehension
You are not alone. BuTTTT - if you take your time, you can actually do this. Don't sell yourself short.
It is so relaxing watching milling with some piano.
Incredible timing, I just added 50 Nema23's to the shopping cart today:) The drivers are a lot more expensive than for the little ones. But i need the POOWEEERR!:) 10x for the walkthrough (and the mistakes, so we don't have to repeat them:)!
"The confuser." :-))
Just get a bloody CNC machine :D
Just watched the whole video how is that any easier than CNC?
The learning curve of what you have done is is pretty high and you could just make the CNC gcode for that pretty easy by hand.
Plus the reward for getting into CNC is much higher.
Dave Webster u mean just build a cnc already :)
bryan gorski haha yeah thats what I meant to say!
I just rebuilt a 4 Axis engraving machine (suregrave) last month from its dead proprietary controller to gcode and the process of getting upto speed wasn't to bad once you get going.. maybe 50 hours total from start to being fairly competent in the basic operations.
***** thats exactly how I did it TBH but I found some hurdles along the way. If i'd stayed with imperial and not hit issues then you could drop that to about 15 hours.
I see in your notes you wrote "solidworks". I used to use that. Fusion 360 is the new truth and the the light! Free to hobbyists and start ups! $300.00 american per year if you buy it! So cheap, or free! Go right from modeling to programming and generating (god forbid GEE CODE) gcode. Solid works is $3500.00 for single seat license and $1700.00 per year (every year) to use. Plus you have to buy an external programming gcode generator on top of it. I am not being paid to say that, I have their software and I use it. I just think it is the new hotness based on price and useability. You should check it out.
I love the arduino demo. Great job! Great technical breakdown to follow at home!
I love Vijeos like this because they give me that cool kid knowledge when im sitting in the back of my robotics elective with the head bangers and the wacky tobacco boys
You've got a problem? Yo, I'll solve em. Check out the beat while the stepper's revolvin.
GRBL goes into arduino... and you control 3 axis...
Teacup in arduino - and you control 4 axis. Even with a UNO...
G code converters are free.
Is it problematic to use 3D-printer firmware for CNC? I use grbl and it works quite good, but Teacup seems to have some additional neat features. Does it also run on G-code?
Yes, Teacup uses G code. But I am pretty much where you are - tried GRBL on 3 axes, was about to test Teacup, but the machine was very noisy, thus ended up buying a quiet small 3D printer (Davinci mini) instead.
Autodesk has some nice CNC software, though. It supports all types of multi axis machines - 3, 4 ,5 axis CNC for free (student license)... it's amazing. And should be compatible with Teacup.
Do you mean Fusion 360? Yeah, that is great, but still not tested with my CNC. I like milling more than printing, you can work more acurate and with different materials.
Do you mean the machine was very noisy with teacup or in general?
Yup. Fusion 360. never used it though. Not yet.
The machine I got is some old 3 axis stand from the lab. They wanted to throw it. I took it. The thin weights 50kg or so... had to carry it 50 meters, open a door and drag it through two tight doors... and it's one loud son of a diddly... weeee woooooglelele wooooo hooooooglelelelle kr kr kr kr kr kr woooo!! it's crazy loud... but sturdy. I love it. The woman hates it, though. We got a small apartment, and the thing is big, like a 50x50x15 cm platform.
Nice, I hope it's tough and rigid. My mchine is relatively light and also mostly made from spare parts I could gather.
a few points; The current in the stepper determines the torque, the voltage on the driver determines how fast you can reach that current, i.e. how fast you can run the stepper and still have torque. You can run that stepper with 12V you just can't run it very fast.
And if you want to run the stepper fast you need to ramp the speed up and down, there's a limit to how much acceleration you can have before you lose steps
fantastic. what a great dude this bloke is. a real star.
Can't beat a bit of Erik Satie.
He was a character as well.
u should put your confuser in a container to keep the crap out
First off, Love your videos AvE! Please take my comment with a grain of salt. I know you said you didn't want to waste time learning a new way to code and you already had a arduino to make it chooch and stuff.
Even though I don't understand how the data pixies and code bits actually work on this project I've been thinking about it for a while now and I think this project could've been made much simple-er with a small PLC with maybe some small limit switches or timers. In my opinion, ladder logic is much more intuitive and/or user friendly to learn compared to any other code that I have tried.
Anyway, it was fun watching this video. Maybe one day i'll find out what this arduino thing is all about!
Looks like it's time for joining the cnc crowd. 😀. It is much easier then you think. Love the videos!
XD its written on the stepper motor 14:00
I'm getting worried now. You on adderall or something?
I was just waiting for one of those chips to land on the unit and short something out. Glad it didn't happen! Love these videos AvE. We have a two year old and a 1 month old, I know what you mean about free time.
I'm so stoked that I understood about 25% of this.
It's not a very good idea to put the arduino so close to where the metal chips are falling. Could ruin your boards/drivers/motors/day.
Do you really think the resident Emperor of the Empire of Dirt would have it any other way?
Rhetorical question, I suppose?
couldnt find a siemens plc and waste less time?
Where's the fun in that?
Dam, now I have to go back to the dumpster and get the dedicated power supply that goes with the stepper motor and gearbox I found. They pitched some old equipment where I work so I scavenged everything I thought I would need to experiment with a stepper motor. Great video Ave.
At 4:12. AMEN brother. Every idea I ever have ever again needs to be prefaced with at least a fleeting memory of those wise words.
Dude, gcode is stupidly easy. Just learn it already.
0calvin exactly. you can fit everything on a piece of paper and then use it as a key whenever
0calvin, Gcode may be easy, but it's rarely practical to program by hand, so most people probably just trust a program to translate for them.
Makes the most sense to me. I've forgotten gcode for that reason.
Generic Name That's true. I actually hand code on my mill about 75% of the time. I still have to glance at a reference guide sometimes, though, I'll admit. I think for the simple, repetitive tasks that AvE has been doing, such as this video and the lapping machine, writing something in gcode would have taken a lot less time than writing the code for an Arduino.
Yep this is a bit like reinventing the wheel but ending up with a not quite round wheel in the end. Entertaining though.
Yes calvin, that is very true.
12:08 sounds like me....right heyar
I always learn so much from you...thank you!
Amazing. Thank you SO much for putting this video up AvE - this is exactly what I need to help me finish my injection molder :D
+Eaton Asher cool ! Any chance we can get a run down vid?
I'm glad I chose to google d'orbital stellarator when I saw it on that tub and thought "the hell is that?". Well played sir, well played!
Metal chips in your breadboard is a good way to get glitchy! :) great vijeo. Mucho entertainingo.
That was "g-code"? It looked like 'C' programming to me.. probably a hybrid.
Well done video that could be adapted for many purposes! I am glad you explained how to check the motor wires in case the label is wrong or missing. It is a big help if we are repurposing something from the junk heap or out of another product. I enjoyed it warts and all! This was like sitting in a buddy's garage drinking a brew and tinkering with stuff. Keep it real!
The fact that you used Erik Satie's Gymnopedie makes me appreciate you all more Chris.
