  - My OMC 1.8° motors, on the other hand, performed very well even at moderate currents.
 
-- We are derating the motors/drivers for margin of safety. Rated currents are the absolute maximum *in ideal conditions*. In reality, things like chamber and driver temperature come into play. Margin of safety is also standard practice.
-- TMC2209 drivers are rated to 2a RMS, but I would not exceed 1.4a RMS.
+- **Different stepper drivers have different maximum currents**.
+ - See [:page_facing_up: here](https://learn.watterott.com/silentstepstick/comparison/). Try not to exceed ~70-80% of the rated maximum of your drivers (and remember that higher currents need more stepper driver cooling).

 ## Determining Initial `run_current`:
 Start with around **40-50%** of rated current.
