![]() ![]() Now you are ready to embark on an exciting journey of controlling stepper motors using the powerful TB6600 driver in conjunction with your Arduino. 3) write a set of routines that convert the rotary positions into the on-time parameter. 2) write a set of routines that read the rotary positions. ![]() In the 4.5A type, the driver step first becomes 1/8 and then stops because it doesn’t have a 1/32 step.īy following these steps and understanding the code, you’ll be able to effectively interface the TB6600 stepper motor driver with your Arduino and harness its full potential. 1 Answer Sorted by: -1 simple: 1) write a set of routines that drive your servo motor via interrupts: you will need to specify the on-time for each servo channel. Finally, by increasing the step, the motor speed decreases and its resolution increases. By doing this, the driver step in 4A type, first becomes 1/8 and then 1/32. For example, first we set pin S1 and then S2 to off. Every click moves the motor a set distance. Instead I want the rotary encoder to move the motor a set angle on the step of the encoder then stop. the 2 stepper motors The rotation velocity can be adjusted by the code switch. Next, we want to change the step manually by the driver switches. The main issue I am having is the rotary encoders are giving a constant movement in the motors in between steps of the 12 step encoder and stopping on the complete step. wiki:Dual bipolar stepper motor shield for arduino (DRV8825) is a stepper. The motor then rotates by creating a square pulse with the step pin. The rotation direction of the stepper motor is clockwise in 4A type and counter-clockwise in 4.5A type. The rotary encoder I am using is this one.Connect pin 8 to DIR (CW) and pin 9 to PUL (CLK). think its been turned one click forward and then one backwards). This happens with all methods I've tried where one way will turn fine, the other it will bounce (e.g. (New position is number of steps motor should be turning) Moving 2 clicks clockwise.Īdding the stepper line, moving 2 clicks clockwise gives me.įinally if I turn the encoder 1/2 a click at a time slowly it reacts as expected. The position of the shaft varies depending on the amount of its rotation. With the help of two sketches, we will show you two different ways to read the rotary encoders. If I remove the t(newpos-curpos) line it shows as it should in console examples. You need to know the position of the shaft to use the encoder. I have tried multiple different examples and best I get is it works in one direction, this method uses the Stepper class from libary and does not work in either direction. The upper arrow rotates it one step clockwise, and the lower arrow rotates it one step. but turning clockwise it will show counting up, anti-clockwise counting down.Īs soon as I add the code to actually move the stepper motor it goes to hell. Stepper motor NEMA17 driven by driver TB6600 (12V source) should rotate endlessly at a certain speed. Operation Rotation - You can rotate the knob by clicking on the arrows. ![]() If I use code for rotary encoder on it's own just outputting to serial console it appears to work fine albeit a click jumps up 4 positions. However I am having a frustrating problem when combining both. I intended to do this with an arduino nano connected to a stepper motor and using a rotary encoder to simply translate a turn on encoder to a turn on the stepper motor (with adjustments for speed to follow). I am designing a remote electronic focus control for a telescope (to avoid having to touch telescope during focusing causing wobble). ![]()
