Hi there -
I'm trying to learn about how to control stepper motors from this forum.
I need something as-close-to-silent as possible and my understanding is the TMC2209 is the best driver to experiment with this.
However, despite many posts about this driver and a handful of Google searches - I'm finding it hard to get a simple run-down tutorial of how to do this. Can anyone give me a clear-cut example of doing this with an Arduino Nano, a NEMA23, and a TMC2209, for instance?
Thanks!
You may have noticed in your Google searches that NEMA23 just refers to the mounting size of the motor, NOTHING else. No examples can be given without knowing the motor's electrical specifications, and the power supply specifications you will use with the selected stepper motor.
Go thru these:
Sorry, my bad. It seemed to me that 2209s tend to max out at 2.8a - and prefer to run more along the lines of 2a. I was planning somewhere around 12v for a motor. I'm think that puts me somewhere around 2.5kg of holding torque, but if there is a way to get more torque with those specs, I would be open to it.
To get more torque, increase the voltage of the stepper power supply to the maximum the controller board can handle.
Hi all -
I wanted to thank @LarryD for the great info - I have the motor up and running right now.
For other folks who might come to this thread, I found this link to answer most of my questions directly, including code and schematics: https://www.youtube.com/watch?v=7spK_BkMJys
I did have one other brief question, for anyone who has worked with these drivers. I do not seem to get a logic level voltage output from the VIO pin and I'm curious if anyone else has had the same experience.
As a solution, I shared the 12v power supply at the Vin of the Arduino, which I believe has a built-in regulator - and it all seems to be working fine now - but I'm still wondering about what might be happening. Thanks!
