So my idea is to use my bbb as a Linux mini pc, with a cnc program to handle the gcode and then through multiple channels send the info in either pwm or step\dir to the m4f. The m4f would be there to handle all the inputs, and control the h-bridges powering the 3-5 servos. each servo would have its own quad encoder- decoder feeding position back to the m4f. the m4f would handle positioning judgments, then relay position back to the bbb. I would prefer this method because the bbb would have control over each servo with less latency I would think. Is the m4f up to this challenge, or would there be a better choice? I would like to stay away from the classic attiny drivers. Any input would be apreactiated. additionaly I would think this design would be good because with slight changes to the driver side, you could control steppers, or any other type of servo ac, dc, etc, or even steppers with encoders. thamks
