Hello, I’m back to a Project I stopped half a year ago due to school. I have a TMC 2209 V2 driver and a 4.8V stepper motor that I want to control. I wired it up uploaded the code. It’s supposed to make a step every 2 seconds then, pause for two seconds etc. But its just vibrating for two seconds and then pausing for / swconds. Need some help. Thx:)
Here is a picture of the setup:
I moved your topic to an appropriate forum category @rotten200.
In the future, please take some time to pick the forum category that best suits the subject of your topic. There is an "About the _____ category" topic at the top of each category that explains its purpose.
This is an important part of responsible forum usage, as explained in the "How to get the best out of this forum" guide. The guide contains a lot of other useful information. Please read it.
Thanks in advance for your cooperation.
Will do next time. Sorry for that

Please post a link to the datasheet of "a 4.8 volt stepper".
Thanks! In my eys it's a hybrid stepper made for 20 mA current. The TMC2209 is not a matcihng driver. It's designed for Amps. A H-bridge would be better using 5 volt supply.
Which motor wire is connected to which TMC2209 pin?
Set the TMC2209 current limit to 0.2 Amps, step voltage up to 12.
How are microsteps set?
Post your code.
A current controlled driver needs a supply voltage of at least two or three times motor voltage.
You have a 4.8volt/0.2A motor, so the driver needs at least 12volt.
Make sure you set the driver to 0.2Amp or less.

I switched Motors to a KL17H248-15-4A.
Red- 1A
Green- 1B
Yellow- 2A
Blue- 2B
Put the current up 24V and still nothing.. I think i wired something incorrectly but I dont know what.
Thanks. I didnt know how much that motor could handle 
.
I switched motors und gave it 24V. Still nothing..
The driver "gives" it a constant current of 200mA (when adjusted correctly).
Then motor voltage automagically falls into place.
There must be at least four wires between the Arduino and the driver.
Logic voltage, ground, step, direction, and maybe enable.
I only see two wires in post#1
