What is the problem?
Printing is slow and extremely jerky. Circular movements are exceptionally bad. Surfaces are ugly, printed parts are unusable, printing time is much longer than from SD card or Repetier. CPU load never exceeds 20%, there are no low voltage warning nor other errors or warning in syslog/dmesg/messages.
What did you already try to solve it?
Using different USB cables, no success. Works like a charm using same USB cable and GCODE when running Repetier on my dual core laptop. I think Tinker Board S has enough juice to push text through VCOM port and send some JSON junk over the network, so there must be something else wrong.
