I am building a CNC controlled ultrasound device for medical research, I want to use a smoothie board for this controller but I cannot easily find if it can do a few necessary things (easily). For the experiments it will need all used axises to be able to be moved with a keyboard strike, to a varying precision, or sent arbitrary G-code from a command line, and preferably controlled by the computer. Is this possible or are all operations limited to the execution and code contained in the SD card? This may be a very stupid question but everything I have read so far has led me to believe such.
