Multiple stepper motors with joystick, TB6600 and the accelstepper library

[@ianbeaver9627]

Several people have asked in the comments where to find the links to the circuit diagrams and the code etc and this had me foxed for a while too. 'In the comments as always' the Curious Scientist said. But I read all the comments and all I saw was other people also complaining that they could not find the links to the code or circuits etc. 'In the comments' said the Curious Scientist repeatedly. This post is just to let other subscribers know that the trick to solving this problem is that the very top comment, immediately after the video, yes the one with the blue 'Curious Scientist' logo, on my screen at least, has a 'SHOW MORE" button. Click on that and all is revealed.

[@CuriousScientist]

The problem is (and I am not trying to criticize or offend anyone) that people just usually so impatient or lazy. They want everything to be "spoon-fed" to them. I always publish the schematics, the code and often add extra resources, but many people are too lazy to check the description of the video and click on the link. I cannot do anything else but telling them over and over to always read the description. :D

[@Meccanokinematics]

Great vid. The resonance fenomenon van be avoided by using TMC drivers. I have been using all kind of drivers for my projects, like A4988, DRV8825, M415C, HY-DIV268N and a couple of other ones. They all had in common, that they can't cope with the resonance and electrical noise. TMC drivers however are absolutely silent.

[@CuriousScientist]

Thank you! Yes, those drivers are more silent, I have them in my 3d printer and they make a huge difference. They also come with some extra features as compared to the other mentioned drivers.

Dear Sir, your work is fantastic! Could you please tell me how to integrate 2 limit switches ( in other words 2 "if" statements ) into your sketch in order to stop the motor from over-running in each direction but still allowing to bring it back from the "limit"-position? Thankyou in advance.

[@CuriousScientist]

Hi! You can stop the motor after a limit switch is hit and then make it go back until the limit switch is released.

[@diegomonzon]

Thank you for your tutorials, they are all super useful. I am replicating this one with an ST-M5045 driver, a nema 24 motor and a 10k potentiometer. It works, but the speed is not as fast as in your video . I tried changing the stepper.setMaxSpeed(5000); //SPEED = Steps / second and it doesn't change anything. I also tried changing the multiplier (5) in stepper2.setSpeed(5*(Analog_Y-Analog_Y_AVG)); It does get to my max speed faster but the max speed stays the same. Any help is very appreciated.

[@CuriousScientist]

Hi! Thank you for the kind words! If your stepper motor is not as quick as mine, check the following settings: - Check the microstepping - I always use 400 steps / turn. - Change the acceleration (this will not work with the runSpeed() and setSpeed() functions however - use the run() and setMaxSpeed() instead at the corresponding places) - Change the max speed. - Better power supply. (I am running tiny motors, they are easier to speed up) Let me know about your progress later!

[@annamimmocaliandro]

Hi, could you please tell me if it is possible to vary the speed of the steppers? if so, which code in which line should be modified? Thank you

[@CuriousScientist]

Hi! You adjust the speed by tilting the arm of the joystick. Or what do you mean? I explained the whole code line by line, pay attention to my explanation. I don't have time to rewatch the video/search through the code for you and search for the lines.

[@echearista]

Great tutorial! I have a question... the same power supply for both tb6600 are independent? Is there a problem if I use the same for both drivers?

[@CuriousScientist]

Thank you! Of course, you can power the drivers from the same power supply! Just make sure it can provide enough power for both drivers/motors. I used independent power supplies only because of convenience. It was easier with the cabling for me. :)

Hello I don’t know a lot in electronics but what settings do you have on your drivers ? And if I need to increase a microsteps what should I change in the code ? Thanks

[@CuriousScientist]

Hi! Microsteps (and current) are set on the driver. I don't remember the settings, but it is probably written in the code I published. You can check the current needed in the datasheet of the stepper motor you use and the microstepping is entirely up to you.

[@Paravision1]

Thank you for all the tutorials!! I'm trying to remote the joystick via rs485. I've substituted the A0 pin for "int Analog_X = Serial.parseInt();" I can get the joystick reading from the Master arduino on the slave in the void ReadAnalog() fine, but for a reason that I don't understand, I can't use the "int" value from the Serial.parseInt() in the other void events or equations. So the Interval Values are always zero. Any pointers would be gratefully received. Many thanks

[@CuriousScientist]

You are welcome. Did you check if the master sends the values to the serial? Then, are you sure that you define the variable at the beginning of the code and not inside a function? I suspect that you defined the variable maybe twice, once in the beginning, once inside a function. And since you redefined it, its value became zero. But it is hard to say anything helpful without seeing the actual code. (Please don't paste your code in the comments because it destroys the comment section and I cannot read the comments properly).

[@Paravision1]

@@CuriousScientist Thanks for the help. Half way there now! The calcs are working, so stepper is moving with joystick via rs485, but much slower.

[@23szendre]

Nice, thank you for this tutorial! What do you think, it is possible to make a setup like this with 3 stepper motor using an TMC2208 Stepper Motor Driver?

[@CuriousScientist]

Thanks! It would work with "any" number of drivers and motors as long as you have enough pins on your Arduino for that. All you need to do is to define the motors one by one in the beginning, then refer to them in the code appropriately. The accelstepper library works with this particular driver too since it just needs the "step" and "dir" pins. As I added a second motor to the code in this demo, you can add a third, fourth..etc. (AccelStepper stepper1(1,8,9); AccelStepper stepper2(1,10,11)...etc.). Just follow the same strategy. Let me know if you need more help!

Very nice video.. I found it just in the right time for a project I'm working on.. I have one question though, I used the code exactly as it is and just changed what needed to be changed however I don't seem to notice that this library does acceleration or deceleration for high speed movements. Is there a method or a function to accelerate other than setting max speed and setaccelerate?

[@CuriousScientist]

Ummm, if you would have watched the video carefully enough and read the documentation of the accelstepper library, you would know that the runSpeed() function does not use accelerations.

Seems like you haven't read the documentation of the Accelstepper library. Read it and you will see why it is used. It is not a pin definition, it indicates that a stepper motor driver is used, so step and direction pins will be used in the argument.

[@DorfyBoi]

I'm controlling mine via http requests over pygame and a joystick from a client pc. It's pulsing the motor based on how fast the packets are being sent. so the motor cant move fast at all. what method can I use to get the motor to pulse fast, whilst using my x_axis -1 to 1 values?

[@CuriousScientist]

How fast is fast? Stepper motors are not that super fast, they are made for precision and not speed. With proper driving, 2-3000 RPM is achievable, depending on the type of motor and driver.

If you want to control the 3 axes with this approach, you do not need any g code as you have the full control over the joystick and you directly drive the motors. However, it might be a bit challenging or uncomfortable to have all the 3 axes on 1 joystick. X and Y can be on 1 joystick, but for Z, I would use another joystick, or 2 buttons (z+ and z-). I have never worked with any g code related things, so I am not familiar with it.

Hi! All necessary information can be found on my channel and on my website. If it is still unclear, start with a simpler and smaller project.

[@ipadize]

i have a TMC2208 and when i use the joystick to control it i notice that it runs really rough. When i run the Stepper with the Accelstepper Library then its really smooth and quiet. I think thats due to the setSpeed/runSpeed command, i think it would be better if we would calculate the commanded speed but also with acceleration/deceleration.

[@CuriousScientist]

Do you use the same microstepping? It can make the stepping rougher, especially with the lower divisions. The acceleration would be a little bit tricky with the joystick, but could be doable. However, I would write a code for it from scratch.

[@ipadize]

@@CuriousScientist i have set it to 1/16. i just did try out 1/2 step and dividing the maximum speed by 5 and when i hit the maximum speed then the motor runs nice but whenever i dont hit the maximum it runs rough. maybe i need to filter the joystick values but then i still dont have acceleration.

[@ipadize]

also the TMC2208 even at fullstep has a sinusoidal wave output to the stepper unlike for example the a4988 which has a rectangle output

[@CuriousScientist]

@@ipadize what do you mean by the maximum speed, do you mean the setMaxSpeed()? That is the global maximum you can reach with the motor by accelerating or manually increasing the speed to the maximum speed. If your microstepping is 1/16, one turn will need 3200 steps. So, when you are not maxing out the joystick, you are at the lower end of the speed value for the motor. I am not sure, because I haven't used that driver before, but maybe it needs more current when it is forced to move with such microstepping. The acceleration would need a totally different approach, this code is written based on the idea that the user is manually accelerating by gradually moving the joystick to one of its end position. If the joystick is moved in that way, the acceleration is done manually by the user. I do not really see the need for acceleration. Why is it so necessary?

[@ipadize]

@@CuriousScientist yes i mean the setMaxSpeed. Whenever i hit that limit the output to the stepper motor is clean but when its under this limit then the output is "dirty". I have a homing routine at the start which has acceleration and runs completely clean so i think its inaccuracy from the joystick or missing filtering of the values. When the values are stuttering and there is no acceleration then the output will also stutter and make the stepper run rough. I will probably look at the step pin with my oscilloscope. i currently build a focus stacker for my camera which will have a linear and a rotary axis (for macrophotography, there is a shallow depth of field so by using a stacker i can take pictures in different positions of an object and then a software will render these images and basically the object will be sharp from front to back). Acceleration for jogging is not necessary but its nice to have. For the moves between images i will just use moveTo() and run().

That's a hefty motor indeed! First of all, we have to make sure that the power supply you are using is capable of supplying at least 3 A. But 5 A would be even better to have some safety margins. Then, yes, you need to play around with the DIP switches. Make sure you flip them to a position where the driver can provide at least 3 Amps. There are many different drivers out there labeled as "TB6600", so always refer to the text on the enclosure. But as I can see, "OFF-OFF-OFF" on the 4-5-6 dip switches should provide high enough current.

Hi! First of all, copy-pasting the code is not a good idea because it is really hard to read it. Second, don't expect me to troubleshoot the source code for free, I am not a free support service. Check the cables, connections. Make sure you use the enable pin for the motor driver. Make sure you have the right polarity on the motor. Try swapping the DIR and STEP pins.

Thank you for your quick reply. the enable pin for the motor driver must be hight and connected: on your diagram "Let's discuss different stepper motor drivers" it is not connected. to help me solve this code you asked how much? now I have an error code: C:\Users\Laurent\Documents\Arduino\sketch_feb10a_2022_02_10_stepper_library\sketch_feb10a_2022_02_10_stepper_library.ino:11:9: error: #include expects "FILENAME" or #include .........stop for tonight

@@endurobikeparts3092 Not all drivers/boards require it, but some do. I can't see your circuit, so I cannot tell how it should be connected. If you follow my tutorial, it should work as I show the working example. You can see in the video that it works. For business inquiry, you can contact me via email.

hello, this morning I redid all the possible tests; with a DM542.....arduino uno.....arduino nano driver. I checked my voltages 5V and 12 V. checks all my connections.....connected like your example. with the complete code and also the simplified code for an engine. Nothing happens, it doesn't work for me... I'm going to try a simpler code with the Stepper.h library to see if I can get my Nema 17 to run..... It doesn't matter that I ask you again, I have to find the problem I have with my components..... thanks again for your advice.

Good luck with the project, I hope you will make it work!
