Beaglebone performance

Hello,

Gcode file: www.dropbox.com/s/q6pc4gpf4kry373/20_01.NC?dl=0

Raspberry pi3 runing: www.dropbox.com/s/fpwfrnhwtzxk6qk/20170322_000744.mp4?dl=0

I try this gcode on Raspberry PI3 and the graphics performance is very poor... can someone test on Beaglebone and post some video

Beaglebone video performance is typically even worse than RPi.

You could try a GUI which doesn't have the OpenGL preview, such as Touchy.
