How Do We Stop This Motor After FEW Rotation Also One Motor Should start BIT later can u help on this

@TheBoredRobotLLC

3 жыл бұрын

For the rotation question, keep a counter of how many steps the motor has taken. If you know the number of steps per rotation, you can stop the motor after a certain count has been reached. Otherwise you'll need an encoder. To start one motor a little later, the simplest way is to have a "while" or "for" loop inside of the setup() that only runs one motor for a certain number of steps. Then run the same simultaneous code in the loop(). There are a number of other ways to do this efficiently as well.

Hi I want to control 14-15 motors I that possible? Thanks

If you want to control all of them independently, you certainly can't get away with an Arduino Uno. You would have to look into more professional options, possibly a mega, or multiple boards.

Hi - thanks for this! Interesting - with a standard CNC shield with DRV8825 driver and 3 Nema 17 steppers, I actually changed from millis() to micros() which actually gave me full range of speed control . (Couldn't get it to run under millis()) So - able to run the three simultaneously at different speeds - perfect! On the board you set MO/1/2 via jumpers so no control there after set up.

That driver should work for stepper motors. You just have to confirm that the current of the motor doesn't exceed the limit of the driver. I used this driver, because it just happened to be the drivers that I had laying around when I decided to make the video.

@@fernandopalacio4026 Hi Fernando - moving of 2 axes is already in the library. What I did was to expand that (copied the routine) and added code to take account of a third axis. Basically as you go from one step to the next you see which axis has furthest to travel. This axis stays at the normal speed. The other 2 axes then have their speeds reduced by the ratio of their distance to that of the longest distance. In the same routine I also move 3 servo motors. So from a file with the robot going from step to step I have the full position moves for each motor line by line. The total move sequence is set into an array and the relative calculations made. Sorry, but I don't know how to send the code.

Thanks for the question. The point of this example was to show how to avoid using a delay, as it will delay the entire program and you won't be able to run the motors at different speeds. What I'm actually doing is keeping track of how much time has passed and saving it to a variable. If a defined amount of time has passed, I send "HIGH," and reset this variable. This is done independently for each motor.

In order to change the speed of the motors over time, you might want have another set of timer variables to keep track of the absolute time. Then you would adjust the motor speeds depending on how much time has passed. I would not use delays in this case.

@@TheBoredRobotLLC Ok. Thanks. Are stepper motors right for this? It’s a roll roll gimbal, with one axis rotating through several revolutions and the other axis going from about -80 to +80 degrees. I have a mental design for the gimbal, but am unfamiliar with motors or controls. I have equations that represent the rotation speed of each axis as they work together. Can I put the equations in to the software so it can evaluate the speeds real time? Or maybe the derivative for the relative changes in speed. .

Hi, great video. I'm very new to arduino and having a bit of trouble understanding the basic language used in arduino. Im used to programing cnc machines but cant grasp this. I'm trying to get a motor on each end of a shaft, and then rotate it at 120 degree intervals, can I get the 2 motors to rotate in different directions but by the same amount using arduino? Have you got a text document for the programing anywhere that I could use to understand this (I've watched video but not clear enough to copy). Many thanks

I wrote a blog entry to go along with this video: www.theboredrobot.com/post/simultaneously-controlling-stepper-motors-with-arduino For your problem, are you trying to have two motors spin the same shaft? If so, you use the same step signal to initiate the movement for both motors. For the direction, the "DIR" pin on the controller should be sent a HIGH value for one of the motors and a LOW value for the other motor. I don't know the application, but perhaps an alternate solution would be a single motor on one end and a stable bearing on the other end of the shaft.

It depends on how you want to wire it up. With that many actuators, you would probably run out of pins. But since they are all going at the same speed, you may get away with sharing pins for multiple motors. I recommend planning it out with a circuit diagram first.
