Hello, It works now ! The only problem is that the acceleration seems to be a bit different than the original GRBL. I set the "x max rate" to 4000mm/min...

I just changed the line 1082 of stepper.c from **TIM_TimeBaseStructure.TIM_Prescaler = 3;** to **TIM_TimeBaseStructure.TIM_Prescaler = 2;** and now works a bit faster.

I set the speed to 1000mm/min and made the machine move for 1000mm. It stopped after 1:34" so it was 34" late... I am doing the changes you suggest and...

Now everything is good! I changed the PLL_M to 8 and everything is fine! Thank you very much for the help. I really appreciate it!

It was my first "touch" on the STM32 but you are right, they are complicated a lot. Thanks again for your help Nikos

Hello, I cannot clearly see the error you get from the screenshot, I suspect it has to do with the **Serial.c** Have you followed the **Step 1**? https://github.com/SourceRabbit/RabbitGRBL/wiki/How-to-Compile-with-Arduino-IDE "Copy the...

Ok. The error has to do with the Serial.cpp and has to do with the **Step 1** of the How-to-Compile-with-Arduino-IDE Have restart the Arduino IDE or the computer?

@Christo-Fourie I can arrange a remote desktop session in order to setup the environment on your computer and debug the code. If you are in, perhaps you can find me...

@Christo-Fourie Solution No.2 Use the v1.0.6 esp32 package with the Arduino Boards Manager
