Is it perhaps related > to the period of the servo loop? It shouldn't be. All the outputs are written every cycle whether they need it or not. The code that generates the error is here: https://github.com/LinuxCNC/linuxcnc/blob/af15a4d90e1d51d5309db65fe1c9511e486df411/src/hal/drivers/mesa-hostmot2/tram.c#L196 But I seem to recall that the driver maps llio_write (and presumably to llio_queue_write) to different functions depending on the connected hardware. How are you enabling the amplifier? Can you show us the code that causes the problem? Also, which firmware are you using? -- atp "A motorcycle is a bicycle with a pandemonium attachment and is designed for the especial use of mechanical geniuses, daredevils and lunatics." — George Fitch, Atlanta Constitution Newspaper, 1916 ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
