Hello, I'm new to linuxcnc. I want to port linuxcnc to ARM9(IMX257) . but when i test linuxcnc with a nc program on my ubuntu pc in simulation mode(configs/sim/axis_mm.ini, G64 P0.005, max_velocity is 200mm/s, max_acc is 1000m/s2), it is very slow compare to Power Automation CNC(PA8000, based on windows) with same max velocity and acceleration. PA8000 has looking-ahead with 200 blocks. I googled internet, someone said that linuxcnc G64 lookahead is only one segment 'deep' . Is it possible to increase more lookahead blocks?
