Trinamic stallGuard2™ and coolStep™ 

We are currently building products based on TMC2130. Awesome chip! SPI is really nifty.

Fantastic technology. No end stops simplifies a lot of designs

very cool idea.

Nice design

There is a lot of talk about making end detection accurate and repeatable, especially for the Z axis of 3D printers. How does using stallGuard as "crash detection" fare in regards to this? Is it suitable for a Z which needs say 50um of accuracy and high repeatability, or only suitable for X and Y which are only used as reference points to move away from?

ich dachte man sagt Moin!
