Arduino BIG Stepper Motor control. Rotary Axis for milling machine.

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.
Long term projects here: / ave

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...

[@TheWireEDM]

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.

[@fuzzy1dk]

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

Hi AvE, love the show, i'm in Canuckistan myself just outside Torona :) Re the stepper (Incase anyone else wants to follow along) and to save them blowing up shit unless they want to. The stepper is a nema 23 not a 34. big difference in many ways. the 70V is the controller max, the stepper spec is 3A and 1.6uH (Inductance), The volts that the supply can be is calculated from this but if you put 70V right to the motor it would let out the magic smoke big time as its resistance is only about 1ohm, they operate on reactance. The calc for optimal torque is simple enough to do with the old slide rule 32 * VL = VMAX where VL is the inductance so simple 32*1.6 = 51V, so the limiting factor is the stepper, not the controller. 48 is more than enough though for most cases, 70V will probably cause the stepper to overheat, as would the apparent 4.5A you were pumping into it there :), based on the clamp meter reading. 70V would not produce any appreciable increase in torque vs a 48V psu, either way None of the 70 pixies is applied to the motor in a DC Volts sense, its a pulse so the inductance of the motor limits the current for a very short period, the controller cuts it off at the right time before it fries the motor. lastly, microstepping makes the movement smoother (Changes the shape of the pixies applied to the motor toward a sine wave vs a square wave which is the case with no microstepping. At low speeds it makes little difference, at high speeds it helps alot Microstepping rarely does anything for accuracy though when above about 8 or 10 microsteps The GeckoDrive folks have some great info on how to work all this shit out if you or your viewers are interested... here:- www.geckodrive.com/support.html/

I can't stop myself from posting this. As a CNC machinist G & M codes are really easy to learn. Each machine is a little different. But for the most part it takes 10 minutes to write a program without using drafting software at all. You're obviously a very knowledgeable guy take a couple of hours and learn G codes. It's the Mcodes that normally do you in. M codes are machine function codes like turn on cutting fluid pump / turn off cutting fluid pump /rotate left / rotate right that type. G codes are the numerical ones that work with the input numbers. G0/G00 =rapid movement to a certain spot (NUMBERS) G1/G01 interpolated movement to a certain spot (NUMBERS). Dude it's easy.

[@BerndFelsche]

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.

I bought the same 4th axis from China but had to completely rebuild it. They used tiny little MXL pulleys and belt that had a ton of backlash and no rigidity. To tension the belt they slid the motor pulley farther on to the shaft which is a really crappy way to tension a timing belt because it causes misalignment. I'm glad to see that they are making a beefier version that will actually work for light-duty CNC machining because the version I bought wasn't even robust enough to use as the 4th axis on a laser despite the fact that they marketed it as a CNC 4th axis.

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 (

[@jobturner7925]

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.

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!

[@1pcfred]

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.

[@JBFromOZ]

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

[@1pcfred]

Bit late to the party here, but having recently dove back into Arduino skullduggery, I've found that the "glitching" with the aforementioned DIY electroonics---particularly when return signals are needed---was due almost entirely to dirty signals coming from the Arduino board. For reference: Using the genuine item here, not the any of the myriad of fly-by-night knock-offs of the Arduinos available on the intnerdwebs. Adding some electronic smoothing circuitry to the return signals made my day. This was after banging my head on the table constantly thinking it could only be the dodgy USB cable powering the cobble-rigged-setup.... which, in fairness, was partially to blame as well, switching to better quality USB cable & signal smoothing tweaks did the trick. Resistance test your USB cables! Doing so set a light bulb off, which lead to taking a closer look at input/output signals elsewhere. Making sure your supply voltages are stable is also key. #FocusYouFark

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.

The optimal combination of motor properties for this project would vary considerably from those best suited for a CNC machine or blender. If you were doing something similar, how would you go about it? PS -- If it doesn't already exist, someone should really make an electric motor flowchart or web app.

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?

[@TomasSab3D]

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.

[@CatNolara]

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?

[@TomasSab3D]

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.

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.

Metal chips in your breadboard is a good way to get glitchy! :) great vijeo. Mucho entertainingo.

[@AdamCchannel]

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.

[@ProfRonconi]

Do you really think the resident Emperor of the Empire of Dirt would have it any other way?

[@AdamCchannel]

Rhetorical question, I suppose?

[@WrankledEngine]

Sir, you are truly a pioneer. I love your content. Fabri-cobbling!

[@SaintBrick]

I'm getting worried now. You on adderall or something?

[@mausball]

AvE, I use the TI DRV8711 at work a lot. External fets mean you can pick your power. It's got a TON of tunability. It's a wonderful controller, and programs over SPI. If I ever get around to building a CNC mill, the NMEA 24 motors will be driven from homebrew 8711 drivers.

[@cakeswithbutterandsteroids7700]

couldnt find a siemens plc and waste less time?

[@franknewling1139]

Where's the fun in that?

[@ChrisKoch]

I love the direction you took this video. Some of my favorite content on your channel :-)

Dude, gcode is stupidly easy. Just learn it already.

[@SeaCowsBeatLobsters]

0calvin exactly. you can fit everything on a piece of paper and then use it as a key whenever

[@HaloHunter2552]

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.

[@0calvin]

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.

[@datalorian]

Yep this is a bit like reinventing the wheel but ending up with a not quite round wheel in the end. Entertaining though.

[@HaloHunter2552]

Yes calvin, that is very true.

[@slavko321]

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:)!

[@StormbringerMM]

Man the hobby shop machining trail is almost as expensive as my date nights with El Chapo - you, Tony, Joe, and Abom are a bad influence! Thanks for the vid - from the other side of kanukistan - also congrats on breaching 400 thou

[@Hackerspacetech]

I have an RSS feed on my blog and it picked up your video. What a gem of a find!

[@markmorton2519]

Tip for your next not a CNC build ;) - Rather than Ohm-ing out the stepper leads to find the pairs just short two leads and give the shaft a twist, if they're paired it'll be a lot harder to turn.

[@justinhillpac]

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.

[@pondbear71]

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

[@Justone177]

Don't blame Tony for this, you know you wanted to have fun!

[@rotoole6875]

Lol amazing vid. Very clear. I love the recap at the end.
