MPCNC with TMC2209 driver

I bought a set of TMC2209 drivers from Amazon to replace the DRV8825 drivers on my OPEN-CNC-Shield. Background was that these drivers should be much quieter, have more adjustment possibilities and have a better cooling behaviour.

Here is the video:

My conclusion

The expectations have been confirmed. Especially with a laser on the MPCNC, the fan of the power supply is virtually all that can be heard. Also the drivers, even without active cooling, were still cold after 20 minutes of lasering. The DRV8825 would have overheated without active cooling and would have had step losses.
