Arduino with AccelStepper library and TB6600 stepper motor controller

[@F111BMATHIS]

This is it! So PUL+, ENA+, and DIR+ all to 5V, type in a "C" to serial monitor to get all the commands. Command example would be "R 2000 1000" Rotate +, 2000 steps? at 1000 speed? Still figuring it out, but I love it!

[@CuriousScientist]

Why don't you watch the video and read the code? I explain the answer your question at @14:58... The motor will only move once with this code, since it moves on an absolute scale. You might want to use "P" if you want to move let's say 1000 steps, then pause and do something else, then move 1000 steps again.

[@ortizenrique]

Nice implementation, I just had one problem with it, I had to remove the default case in the serial switch otherwise it will only move one step regardless of any command I give to move at any direction, regards!

[@CuriousScientist]

Thanks! That's interesting, I will check it. I uploaded the code as it is presented in the video, so it was working for me with the default case as well.

[@sshah876]

Awesome tutorial, after movement or so the motor is hard to turn by hand it appears that it is consuming current and is getting hot, looks like that disable output function is not working in my setup, don't know what could be wrong, my setup is same as yours do we need to use the enable input in the tb6600? second question is can you embed your limit switch in this code ?. cheers

[@CuriousScientist]

Thanks! Check my more recent videos. I have implemented 2 limit switches and also an option to turn the power on\off via switching the enable pins on the motor drivers.

IF build own cnc router, some basic rules have, you need first minimum nema 23 3Nm /450 Oz torque motors, then stepper motors drivers etc, DM554 or 556 4 or 6 mean max current for motor, need be drivers more handle current than motor maximum have not burn driver, normal used 3-4Ampere motors, power supply need be if use 3 pcs 4 ampere motors maximum need be 3x4=12 ampere power supply minimum. then need cheap 10-20$ breakoutboard, paraller port or USB port, parallerport better safe board, and parallerport pcie card to computer, 7-14$ and best easy FREE software controller all machine linuxcnc, i use version 8.2.4 worst cnc can build whit arduino and cnc shield but not have millin cnc only draving pen plotter or laser or 3D printer used. windows and USB port can use only mach3 software and not have real time controller and thats mean not have safety. better use factory quality safe controller thats can use only linuxcnc and paraller port controller have true real time controll and safe.

[@davidstewart5291]

Great video. You are putting up video of projects that are the next thing on my mind. But there is a bit of an issue that I really want to clear up. In the first part of the video, you moved the stepper by 1500 steps or 3 cm. But in reality the stepper moved something like 3.6 or 3.8 cm. Even after taking into account the fact that you used a cardboard to attach the linear bearing to the moving block, this is a significant gap. What extra thing should I do to precisely move 3 cm? I am aiming for an accuracy of 0.01 mm. I am going to build a similar configuration but use TB6560 and also a backlash prevention nut. I am also going to use the same type of lead screw.

[@CuriousScientist]

Hi and thank you! The lines on the aluminium profile were not perfectly 10 mm apart and also I recorded everything with a tiny action camera, so there is always some distortion. If you use an anti-backlash nut, and you do not overload the lead screw mechanically (which would lead to skipping steps), it will be very precise. If you want more precision, you can use a lead screw with finer threads, for example with 1 mm pitch. The one I use is a 4-start 2 mm pitch lead screw, so one turn results in 8 mm linear displacement of the nut.

[@-RullySianipar]

where do i put the tb6600 ENA+ pin to arduino pin? can you give us the wiring pls?

[@CuriousScientist]

You only need it if you want to manually enable/disable the power to the stepper motor driver. In that case, you can pick any GPIO pins. Then you just need to tell the accelstepper library this pin (see setEnablePin() function) and then you use the enableOutputs() and disableOutputs() functions.

Ok tks. I loaded the code for this video, but when the engine stops (With "S") it gets stuck and consumes approximately 0.650a. The stepper.disableOutputs () function; shouldn't I prevent this? The ENA- pin in the photo of this video appears connected to the arduino. In your blog the photo says that it is not to connect this pin (ENA-) or am i mistaken?

[@CuriousScientist]

For some reason, my reply disappeared. The disableoutputs depend on the board you use. It will not always work. The wire goes into one of the holes in the PCB of the Arduino. I just use it to hold the Arduino in the breadboard. It is not in an electrical connection. If you watch it carefully, you can see that it is just a hole and not an electrical terminal.

[@paulocella9745]

HI ! In the code comments you write: "// We only use non-blocking commands, so something else (should also be non-blocking) can be done during the movement of the motor." does the command below block the code ?: Serial2.print ("tm0.en = 0"); // (using arduino Mega and Display Nextion - serial2) Serial2.write (0xff); Serial2.write (0xff); Serial2.write (0xff); I have a stepper motor control project and a timer, based on your code, and when I send this command to the Nextion display , for stop the timer, the motor stops momentarily. Would you help me? tks!

[@CuriousScientist]

Hi Paulo and thank you for your kindness! ;) Anything that keeps the microcontroller busy is blocking. This can be anything such as reading a sensor, sending data through the terminal, printing values on the LCD...etc. So, I would say that the above code is _blocking_ for sure. The idea behind the non-blocking instructions and stepper motor control is that while there is time between two step pulses, the microcontroller can do something else. The higher the speed of the stepper motor, the smaller the distance (time) between two step pulses. Therefore, you have less time to do something else. The reason why your stepper stops for a little moment is probably because the above set of commands take more time than the time between the two step pulses. Serial.print/write or any serial related command is relatively time consuming, so if your stepper is not "slow enough", you will always experience the little stops. Do you really need to send the "0xff" three times? There, you can cut back some delay. But, to run the motor and the display at the same time, Arduino is not necessarily the best solution. You can use 2 Arduinos. Wire them together. The master takes care of the screen, sensors....etc. The slave just receives the commands from the master and performs the stepping. I already implemented this, but haven't yet made a video about it. Since this can be interesting and useful for many people, I might make a video on the topic soon.

THANK YOU SO MUCH, THAT IS THE BEST CODE FOR STEPPER MOTORS. Would you please give some advice on how to give the required Torque to the motor? My guess is to make a lookup table. I have an MST342 Stepper and I want to make a closed-loop to damp the vibration on a 100 kg flexible robot. The controller that I have designed calculates the amount of Torque to be given to the motor. also, there is no encoder on the motor.

Thanks! You need to be able to measure the torque somehow to be able to control it.

[@amirmkr547]

@@CuriousScientist Can Arduino measure the torque by the current, since in DC motors T=c*I and c is a constant?

[@CuriousScientist]

If you know the value of the constant, then you can just use an external circuit that can measure the current with high enough precision and program the formula so you can calculate the torque. Looks straightforward.

[@amirmkr547]

@@CuriousScientist I don’t want to use external circuit, since they are already built and packed. For stepper motors there is a curve between full-step/s and Torque and that’s in the nominal current. In my case that’s 7nm in 1000 fstep/s with nominal 9.5 phase current. I guess there should be some way to program Arduino to adjust the current to give 5 nm in 1000 fstep/s.

[@CuriousScientist]

I would think that those curves are also a function of load to some extent. Different load would require torque that would also result in different speed, I guess. I am not entirely sure. But if you trust the motor and you say it will have the torque at a certain speed, or the other way around, then it is just simple mathematics. Since you dictate the speed, you can use the value of that variable to calculate the torque.

Hi! Sorry, but I won't go through your code, as I do not have time and resources to do these kinds of works for free. However, one part of your sentence struck me and I think I know what is your issue. You said you use the stepper.disableOutputs() to stop the motor. That is not correct! That just disables the outputs but does not stop/finish the instruction. It just "removes the power" from the outputs for the stepper motor. The rest of the command will be suspended and it will be continued once you enable the outputs again, because the motor still haven't reached the target position. The correct way is to use stepper.stop() to stop the motor because this command resets the target position to the position (or very close to that) where the command was given. Also, avoid using Serial.println when running the motor as it will slow down your motor.

Sure, it is absolutely possible. And it is done in the same way as you just described. You tell the code to go a certain distance with a certain speed, and then just change the parameters. But 420 RPM is somewhat high, so you'll need acceleration and maybe even a larger motor depending on the load.

bro did u use arduino 1.8 software for code

[@CuriousScientist]

For presenting my code, either I use the general Arduino IDE, or sometimes I also use Visual Studio. For developing more complex code, I use Visual Studio with Visualmicro.

Thanks for the amazing effort that you put in those videos. How do you calculate the linear velocity of the power screw? Do you multiply the pitch*rpm*pi/180?

[@CuriousScientist]

Hi and welcome! The linear speed is calculated in the following way: You know that you stepper motor has to do a certain number of steps to rotate the shaft 1 full turn (360°). Usually, this is 200 steps. Supposing that you use a "full step" microstepping, 200 steps of the motor will rotate the shaft of the stepper motor 1 turn. If you for example want to reach 60 RPM, that is 60 turns per minute -> 1 turn per second, so 200 steps/second. Now, we move to the lead screw. The lead screw's most important parameter here is the pitch. If the pitch is 8 mm (usually a 4-start lead screw) it means, that one turn of the shaft will cause 8 mm linear displacement of the nut. So, for example 200 steps will move the nut 8 mm. 200/8 = 25 -> 25 steps will move 1 mm. Now you know the steps to move 1 mm as well as the speed. 25 steps/s on the motor is 1 mm/s on the shaft. So, with full step microstepping, the magic number is 25. Example: you want to move 14.3 mm -> 14.3 mm * 25 steps/mm = 357.5 steps. Similarly, if you need for example 10 mm/s speed, then you need to move 10 mm/s * 25 steps/s = 250 steps/s.

What was the approximate total cost for the project?

[@CuriousScientist]

You can easily estimate it yourself because I published all the parts I used. Sorry, but I don't have the time to summarize it.

[@mattivirta]

stepper motor 5-50$ ,driver 8-14$ ,power supply 10-30$ ,arduino 3-12$ ,hardware what need build. screws,linear rails,bearings, etc.

[@paulocella9745]

how to configure the motor to run continuously in one direction and stop only at the "S" command?

[@CuriousScientist]

Check my other stepper motor-related videos, you will find the answer in one of the videos/source codes. Also, if you watch my videos carefully, you will be able to write any kind of code for stepper motors easily.

[@aashishsahu5448]

have you code for three motors? this is only for one

[@CuriousScientist]

You can easily expand it to three based on my other examples.

Hi, I am an electronic engineering college student living in Korea, and Arduino has a problem with slowing down, so can you check the code?

[@CuriousScientist]

Hi! What do you mean?

@@CuriousScientist We're having a hard time writing Arduino codes that accelerate each using five motors. Can you take a look at our codes?

[@saeidkasraeian190]

Help me please 😭 I have a project like this with some differences. If the 0 position was in bottom and by pressing the button once it starts to Go up and down.i forgot explain that there are two micro switch in top and bottom.when object hits every micro switch it will change the direction until i press the button for second time.and by this the object goes to 0 position automatically and finish.🙏 Please tell me how programming it. Thanks a lot 🌹🙏 For more information when I press for second time, the object might be very point of the path.imagine we don't know where is the object.and when we press the button for second time the object goes to homing point or zero point.

[@CuriousScientist]

Hi! Watch my other, more recent tutorials, I talk a lot about limit switches and their usage in different cases.

No. The max RPM value of a NEMA 17 is around 1800 RPM.

@@CuriousScientist thnx sir coz i try many times to change the code but cannot do any change

[@CuriousScientist]

You should keep in mind that stepper motors are for precision operation and not really for high speed operation. Use some DC servo if you need such high speeds.

[@andrewdollins2321]

No that is not a good library it is not giving you accurate positions it is overshooting by alot.

[@CuriousScientist]

Are you sure it's not your system? I haven't noticed any positioning issues with the library yet.
