[2.0] MKS Gen 1.4 TMC2208 - MONITOR_DRIVER_STATUS only last Driver Enabled

[TiToMoskito]

I followed this german guide (http://3d-druckerei.blogspot.de/2018/03/blog-post.html) to integrate my TMC drivers into Marlin. And it looks like only the last driver "E0" is activated.

This is a limitation in the software serial library where only the last communication attempt works. Your driver should work fine but the reading capabilities are limited for now. So it's a known problem with some ideas for a solution for now.

Okay thank you very much 👍

@Rexima Did you use the pinout as described in that guide? I thought we could not use that particular config as some of those pins don't support Rx

@Rexima problem solved? then maybe hit the close botton below
