1) Tom, the THC part seems incredible! And it rises a lot of questions because in Your HAL file You have: # Load realtime hal components for THC loadrt mux2 count=19 loadrt mux8 count=14 loadrt sum2 count=14 loadrt comp count=15 loadrt limit3step count=14 loadrt ddt count=14 loadrt minmax count=14 loadrt not count=14 loadrt mult2 count=14 loadrt hypot count=14 loadrt and2 count=14 loadrt debounce cfg=1 In wiki I did not see any file for a diagram, but HAL file comment says: # Define Singals (see block diagram for comments) Any chance You might share something, because now I do not see a chance to understand the logics, how is all the THC thing working. 2) I have another 2 questions about the servo motors. Do I understand correctly from the link in wiki page that You have brushed DC servo motors? And what is approximate travel distance on x and y joints for a full turn of motor? 3) Any particular reason to run the servo drives in step/dir mode? In Granite Devices homepage I see that the drives accept also pwm signal, which can be created in Mesa card just as easily as step signals. Thanks and congratulations on finishing such a nice and pretty sophisticated project!
