Off the top of my head (guessing). From: http://linuxcnc.org/docs/html/config_emc2hal.html it states that motmod loads this way: " loadrt motmod [base_period_nsec=period] [servo_period_nsec=period] [traj_period_nsec=period] [num_joints=[0-9] ([num_dio=1-64] num_aio=1-16])] " It may be that the period naming isn't free form? Also the periods should be whole multiples of each other, but I think the periods will be rounded on loading rather that giving an error? This shows a free form thread naming without motmod: http://linuxcnc.org/docs/html/hal_hal-examples.html " loadrt threads period1=1000000 name1=thread " I don't know if the two lines can live together. -- Kirk Wallace http://www.wallacecompany.com/machine_shop/ http://www.wallacecompany.com/E45/index.html California, USA ------------------------------------------------------------------------------ Protect Your Site and Customers from Malware Attacks Learn about various malware tactics and how to avoid them.
