My stepper project:
Original ft plotter with two steppers.
The controller is a Raspberry Pi 3 with motor/stepper head with as OS Windows 10 IoT and as integrated development environment MS=Visual Studio 2017 community (C#, VB.NET, Python.NET C/C++). Behind this model the old FT Roboter and a more recent FT Robot.
At the left the FT-Bot (design C.van Leeuwen) that has been used during the Robot skills in Canada some years ago. Here is in use to demonstrate the use of a SLI. An SLI is an in C/C++ writtenlibrary that contains several RoboPro elements.
