Please always remember that each video you made like this, there are thousands of people learning from your great experience. I highly appreciate your efforts, and wish you all the best my dear.

"Taking some big steps today" ....I see what you did there, and I appreciate it.

Well, short of you coming to my house and connecting everything together, I believe you just made it as simple as possible!!! Thank you! You got yourself a new subscriber!!!!

I dare say that is 'The' place to learn engineering .A fine balance between theory and practice. I wish all teachers were like this. My respect and gratitude to you sir. I really appreciate the graceful ageing you have undergone and how you share this knowledge with the rest of us. Surely age will catch up with us sooner , but to be able to achieve what you do is no simple task. You are truly an inspiring teacher. May God bless you . AMEEN.

I have watched several of your videos. I had an extensive knowledge of electronics that went to waste working for the Boeing company. I did my time. I am diving straight into this stuff to get up to speed. I have several related books courtesy of my librarian wife. They are useful but the videos are just faster to go through and quite specific for a given result. I have some of the components already ordered for my idea. They are due here in two days. Thanks for making such good quality videos! I really appreciate I don't have to rinse some awful background music out with Stevie Ray Vaughan on 11 afterward. You speak clearly and at a tempo that is easy to follow. I'm sure there is considerable effort producing them. It is much appreciated.

Thank you for explaining the sequence of operating of the stepper motor, as a novice it helped me a lot. Good to have someone like you to help out. Thx.

Yay ... thanx to your video I have my NEMA23 (hybrid) servo motor with a 2HSS60 operational with the control of an Arduino Uno. I am in the process now to set up the limit switches and connect this to a linear track such that I can dial in a specific speed and create simulation for testing image recognition and machine learning on an overhead camera viewing a section of the track. . Your videos are excellent and your videos and advice helped me understand steppers/servo controls from every aspect. Bravo!

This video is insanely well done. Stellar format, excellent content, and concise presentation. Definitely helped me out!

While a total novice with electronics, I understood everything you explained. Much of the information you presented, I was looking for. Thank you!

Hello and thank you very much for your videos!! I just want to remark that the voltage shown by the manufacturer is also quite important since it means that the maximum rms voltage drop per coil must be the specified according to the calculation. It doesn't matter if you use a driver that supports higher voltages since it will have some internal regulator or PWM approach to apply the right voltage to the coil. This is important if you build your own driver. If you apply 12 volts directly to any winding you will burn the motor! The maximum voltage drop means that the maximum current is flowing through!

Best vid yet that I've seen for steppers with the controller and Arduino. Good job, obviously a new subscriber.

As always, you have produced another GREAT video and learning experience. You should be very proud of every video you produce. They are the cream of the crop when it comes to educational videos.

I'm retrofitting my old CNC router machine and your video helped me understand a TON about how the components work with each other. I just realized I will need a bigger motor driver THANKS!

Many, many thanks for all of your knowledge sharing. You are a great teacher! I enjoy all of your videos and deeply appreciate all of your time and effort. Please continue to teach and share. The world needs more good people like yourself!

Thanks really appreciate your video. Your coding instructions did not work until I discovered some stray stranded wires had crossed pins on my Arduino, fixing that, everything worked. Thanks again.

You are very good at demonstrating things , u r a good teacher indeed , thanx for making this video, u cleared most of my doubts .

Teaching in a very good manner. Understanding the things even i no nothing about stepper motor.

Dude you are so cool. Thank you for doing this for us.

I have been watching quite a few videos about electronics and Arduino. I did not find any that has a quality that comes even close to what you are presenting here. I am very thankful and consider this a true motivation to continue my approaches. I also mentioned this on a different occasion. Often video in English appear to be hard to understand for non native speakers. This is absolutely not that case with your videos. You are doing a great job in using very clear language that is easy to understand if you are somewhat familiar with the language!

You have THE BEST Arduino channel on KZfaq! Thanks for all the videos!

bro is literly the best teacher ever he just did a full semester in 29min

3:50 you saved my life thank you. i bought a motor without driver and the motor takes 2 and the driver 24 volts and i had no idea how thac could make sense and i was scared to test my mowotor with the driver.

That is the cleanest an most organized shop I have ever seen. Nice video and great explantion.

The quality and organisation of your presentation is only surpassed by your teaching skill. Keep up the amazing work.

Very informative. After I get a chance to build my 3018 I will come back to your vids. Thanks.

watch it a second time after two years. works for me! 👍

your explanations make me wish I had a professor like you at Uni

Great video, one important thing to note is the max stepper speed for an Arduino uno is limited to 4000 steps/second due to the 16MHZ clock speed.

That smirk about bone crushing torque! I would have said it with at least my eyelids wide open. Anyhow, I must admit, these videos are really well made. Very well programmed and designed. Anybody wishing to put more effort in a certain project have all the details here. They would know what I mean when they go out to buy steppers and drivers. One more thing, you remind me of a very loveable character from seasame street. Big love to you to.

Perfect. Your tutorials are very helpful in building confidence of making CNC.

Thank you. This is my first stepper motor circuit. Moving to bigger things now

Make sure you double check the steps per revolution DIP switches on your driver if your motor does not turn or only turns slowly .... don't ask 😁😁😁 HBS86H with Nema 34 is finally working. Thanks for the video!

This was a very helpful video and I appreciate how clearly you explain it, including how to read data datasheets.

Thanks for making the electronics simple and straight forward. I believe i could build a CNC of virtually ANY SIZE with your tutorial.

That's for this video. I'm building a rotary axis for my milling machine for gear hobbing, helical milling, and indexing and while I know what I'm doing with the mechanical build but electrically I've got no clue. I've got myself a NEMA 23 motor and controller as well as an arduino uno.

Thanks for the tutorial,looks like we are moving closer to a ESL for the lathe lead screw I am always following.

You are my best teacher i ever has. Thanks a lot.

Loved this video! It greatly helped me get my setup which is identical working great. I would love to see this setup activated with only 1 push button switch for on and press again for off. Also having the stepper run based on time like 30 seconds at a push of a button then turn off. Also ignore all switch inputs during the 30 second run. I think this would make a very good video and help a lot of people besides myself! Love the channel! Keep up the great work!

Just I started to work with the stepper motor. Its great opportunity for me to startup easily with your explanation. Thank you very much for your information.

There are informative tutorials and those that gonna left you with a great feeling to be perfectly prepared although you gonna put things together for the very first time. You always create the latter ones. Thank you so much. Your techno skills AND your didactic skills are impressive.

You have a great style of instruction - methodical, clear and focused. Thanks for your effort.

My new favorite youtube channel! Such a great content.

This explanation is gold. First try, it worked perfectly. Thank You.

Thank you so much for the explanation and for this video! Just saved my electrospinning project!

So happy I landed on you Channel - top quality instructional video! I am subscribed! Thanks

3:50 was such a revelation :D I always wondered what that means!

The reason a high voltage is used driving a stepper motor is because the supply needs to overcome the back emf generated as a result of the fast switching of the inductors. If the back emf becomes large enough then the motor will not turn, or lose steps since it cannot uphold the torque. At lower speeds and still the high voltage, the controller current limit so the motor's current rating will not be exceeded which will damage the motor. The biggest speed enemy of any frequency driven motor is the rate at which the metal core can be magnetized and then again magnetized in the opposite direction. Amorphous metals are usually used for fast pole changes with the least energy required.

Curious about the description of doubling the amp rating when half stepping, which seems to make sense as described, but then when the torque specs were shown with the 36V supply rating the amps were still listed as 4.2A. I'm just a little confused. EXCELLENT tutorial for a person new to this. Thank-you.

The method of expression and visuals are great. Thank you so much.

Thanks soooooooo much for your detailed and informative video. you are a good teacher for the beginners(like me), speaking clearly and slowly. appreciate that...

Mr. Spock explains electronics. Beam me up! Great stuff! Thank you so much.

This is insanely valuable teaching!!!

Exactly what I was looking for, very helpful in building my milling machine power feed. Thank you your time and effort is appreciated!

Many thanks for your easy to follow videos.

Bill, This is yet another very clear video on what is a difficult topic for some. Keep up the great work!

Very useful. I've been caught by the ENA input on these large driver modules, assuming that ENA needs to be driven in order to ENABLE the motor, whereas driving that input seems to do exactly the opposite!

Wish I had a teacher like you :) . You are doing wonderfull job on all of your videos. Greatings from Czech Rep.

Love you... you helped me solve my project related problem.... ❤️

Hello, This is an excellent work to help to start ; Thanks for your time in showing all of this. Very good lesson and speach that even a French can ! Many thanks - Patrick

I've never heard about AccelStepper library and I discovered because of your video. Thank you.

Bill, I have an arduino project here - - I have a 500 gallon pvc plastic water tank in my yard, to a pump, to water drip my yard. I want to measure the water level and alarm if it gets critically low. I also want to disconnect power to the pump to the yard. This is a watter pressure demand pump and turns on when water is called for by opening the hose. The question - - a water level sensor is required, that is non invasive..can not drill into the tank. If there a sensor that can be mounted on the surface of the tank and then with a change of density of the tank shell and water, detect that water is missing at this sensor point? It needs to take into consideration the mass of the plastic shell and water versus just the shell itself ( no water). Love your series and I watch all of them. You explain very well and teach enough theory to tie it all together. Bob - Brecksville, Ohio

Very informative in detail . Sorry to say for beginners it can be clothier to reality if in explanation was been used three motors .

These videos of yours are a gem.

Thanks for your great lecture. it's very useful for me.

finally a video I can learn something from....thank U so very much.

hello Bill I am learning electronics for a CNC plasma cutter. Torch Height Controller is a bit of a problem to me. I have a lot to learn about CNC in general as an entry level. I could bother you big time for the next few years if you only want me to. I need to learn real stuff not just as a hobby, it is my job already. Your pedagogical teaching style has a big value. waiting , thank you gabi

".... Newtonmeters if that means more to you." Yes, it does, because it is a SI Unit, meaning the only units in which engineers should be communicating in. ;)

the mister rogers of electro-mechanics...and i enjoy the heck out of it.

Great video... Complete clarity on hardware and software architecture and clear communication is the best part of this video. Thanks alot... Can you deliver once video on how to design a DC battery bank capacity for the same application instead of a DC power supply? This will hep us on how to select the appropriate V and Ah for the same application and what electical precautions need to be taken while driving at full capacity and what challenges we can face? Will be happy to hear from you.

Definitely a video with torque, thanks Bill. What do you mean about big? Big starts at 100Nm. Joking, big is relative:) In addendum to your great safety advice: Have a kill switch in range when building and playing with your apparatus. And use your brain before that, keep moving parts enclosed and out of range of your fingers or other body parts, best by design. Often, a well thought-out mechanical design can make some electronic frills unnecessary. You'll need all those considerations when using an Arduino for your end product because this is no industrial device. It can't provide latch-up protection of outputs nor a full blown reliable brown-out detection over its complete specs.

Very good video ! Clear and to the point step by step ! Thanks for sharing !

You are blessed, man!! Very useful video and channel. You have one more follower

Sir I am very thankful for your teaching method.Please keep it up

That thing looks like it could easily break your wrist. Thumbs up, thanks :-) love your videos!!

Your content and presentation & delivery is prefect..... you really nailed everything !! Thanks !! Keep it going !!

Great video thanks. Very clearly explained and gave me the information I need to start a project that will use a stepper motor to drive a wood lathe spindle.

Educational and useful video. very nice. I really like.

Coding issues- in your sketch, you execute the analog read and map function before starting the timing pulses. The read takes ~100uS; as much as both the timing delays at highest speed! Map is also computationally intensive. Better to do the calculation inside the pulse, and subtract the read time from the delay. Map is not really required- reverse the pot polarity, and do pd = 2 * analogRead(spd); Set first delay to pd (it has already taken 100uS to do the read) and the second to pd + 50. Smoother, better range, and less code.

Thank you for a very clear and easy to follow step by step information. Realy helpfull...

I appreciate the effort in making the video, the explanation of how the motor and driver operate, and the quality of the guidance for assembly. Some questions about the set-up: How did you choose the resistor? Why did you wire the POT, DIR, and PUL all together and how does the Arduino dictate changes in DIR and PUL? How do you choose a safe power supply given the motor driver and motor?

I learned more in the past 30 minutes then I have in the past 5 years designing and building a CNC Router. It's too bad that I already bought a higher end Stepper Driver with a builtin Breakout Board. This would have saved me more than a few hundred dollars had it been available 5 years ago. I wish you would explain how to hook up multiple steppers to an Arduino. Then I could troubleshoot my system without having to ship it out of country for diagnostics.

Nice video! Thanks for sharing

VERY GOOD topic, I have been wanting to build a welding rotation holder tool. THANK YOU!

the greatest workshop on yt!! Thanks man!

Thank you for this very nice and clear explanation, it helped me very well. I am using the same stepper motor Nema23 and it is really powerful. My arrangement is Estelcam via an Arduino Mega and the driver DM516T.

Set playback speed to 1.25. Thank me later.

Nicely done. Really appreciate it!

Thanks you for your teaching !

I have been involved in industrial electronics through years in factory maintenance. I have a good hold on the price of some of this stuff. You must either be involved with someone that supplies you with equipment like this or you are incredibly flush for cash. Not that I am dissing what you are doing. You are doing a fantastic job, but man I would so like to be able to afford some of this stuff.

This is an _amazing_ video. Thank you, sir.

Thankyou I got this working, now to modify for my purposes.

Great content. Thank you so much.

Thank you for your nice explanation!

Very informative. Thanks again!

I love the layout of your workshop. I'm going to have to copy some of it; especially having a bench supply built into your desk/shelf.

btw: you should make sure that the highest frequency your arduino puts out is matching your driver. my driver a.e. has a input frequency up to 200khz so i had to change the fifty in "pd = map((analogRead(spd)),0,1023,2000,50);" to a five "pd = map((analogRead(spd)),0,1023,2000,5);" check that or your motor wont spin at full speed.

Fantastic Video. Thanks for the help.

Thank you for the lesson. Great content explained very well.

Minor correction: you use holding torque and stall torque interchangeably. Holding torque and stall torque are different values. Stall torque will be less than holding torque, and is not usually given on a spec sheet because it depends on many other factors. Designing dynamic systems around 80% of of rated holding torque is m/l safe for intermittent motion, or less for constant motion. If you try to design a mechanism around the holding torque value, you'll either upgrade the motor because it can't actually haul the load, or because it released its magic smoke and has to be replaced anyway. Take a look at what Trinamic driver chips do to a stepper motor's rated specs. PFM.

Loving your workshop!
