TMCStepper VS Marlin-2.0.X-MKS-Robin-Nano

Now take a look at the header file of the library TMCStepper you want to use, https://github.com/teemuatlut/TMCStepper/blob/master/src/TMCStepper.h

(...) /** * Beta feature! * Create a 50/50 square wave step pulse optimal for stepper drivers. */ //#define SQUARE_WAVE_STEPPING /** * Enable M122 debugging command for TMC stepper drivers. * M122 S0/1 will enable continuous reporting. */ //#define TMC_DEBUG /** * You can set your own advanced settings by filling in predefined functions. * A list of available functions can be found on the library github page * https://github.com/teemuatlut/TMCStepper * * Example: * #define TMC_ADV() { \ * stepperX.diag0_otpw(1); \ * stepperY.intpol(0); \ * } */ #define TMC_ADV() { } Any thoughts?

My problem is that the library I'm using for the TMC2208 is made for the AVR architecture which means the ESP8266 seems to be incompatible with the code. I belive I have a few options.

The library is called TMCStepper, and this issue suggests softwareserial cannot be used. I have tested it myself and can confirm this. Solution would be to get an ESP32 that has multiple hardware serial connections.

I looked into the code and it turns out that TMCstepper makes use of basically 2 functions to write to the register (here lines 187 and 281), so should the example given above not work you have a second option !

Hi. I flashed firmware from this repo https://github.com/le3tspeak/Marlin-2.0.X-MKS-Robin-Nano to my Sapphire Pro z TMC2209 but my Z axces engine don't work. Who have working firmware to the Sapphire Pro z TMC2209?

No need to be paranoid about updating firmware on a Sapphire Pro ... I am using this repo https://github.com/le3tspeak/Marlin-2.0.X-MKS-Robin-Nano/releases ... it is a Marlin 2.0.6 version ...

I am not quite sure but I think you have to uncomment line 947 in your Config.h

There was already existing a Firmware by l3tspeak on github which was not including configurations for the Hemera nor the Dual-Z Revision, but the BLTouch is already included (As I remember). But I didn't tried that BL-Touch yet. I had no need for that yet.
