I'm using a Wemos D1 R32 with the Hujer OnStep Shield.   Here's my Pinmap line from my config.h file:

#define PINMAP             MaxESP3 //    OFF, Choose from: MiniPCB, MiniPCB2, MaxPCB, MaxPCB2, STM32Blue,             <-Req'd

I renamed the Pins.ShieldESP.h file  to Pins.MaxESP3.h and placed it in the /scr/pinmaps directory.  This is working for me, and I'm using TMC2130SPI drivers.
