Re: Improvements by using TMC2130 driver.

Yes, you are right. Both ICs are from the same family. The main difference is a different pinout and slightly different configuration setup via pins. Due to an additional used pin on the TMC2224 it is possible to switch between stealthChop™ and spreadCycle™ by pin configuration. The TMC2224 can be c...

Re: Improvements by using TMC2130 driver.

Your are right, in special situation the microPlyer is delaying by a full step. microPlyer is used to compensate other side effects that occur when using very low microstepping as e.g. fullstepping. When using fullstepping the system can start to oscillate which can have an even higher impact on the...

Re: Improvements by using TMC2130 driver.

Hi ABH, thanks for effort to integrate the SPI interface to the Marlin Version of Raise3D printers. The microPlyer™ is interpolating the next step with the frequency / speed of the previous step. During acceleration when the next step is shorter than the previous one, the interpolated step cannot be...
