Hi,
I want to take attention to our new product. It is Control System PiDiCNC build on Raspberry Pi 2 and LinuxCNC.
For now we have done with first board for stepper motors based on FPGA. It can drive 4 steppers motors by Pololu DRV8825 directly from
this board or by external stepper driver STEP/DIR type. Max speed is 750kHz. Other features are 5 binary inputs,
3 binary outputs (each can be configured as BIN/PWM/RC servo), 1 relay output, 1 analog output (0-10V, 12bit) and 12 leds. All functions
are available from LinuxCNC by our HAL components. In this moment we made only few boards for testing but commercial production comming soon.
Next boards what we are working on are Analog Board for servo motors, encoders and additional Analog and Binary IO board.
Few slides and video with additional information:
