It would be nice and maybe somebody already have thc configuration so I could reduce number of trial/error iterations. Does anybody know for working thc comp with linuxcnc/machinekit and possibly on BBB so I could check configuration?
I am looking into THC comp (*machinekit\src\hal\i_components\thc.icomp*) I see there are few parameters available to influence THC comp operation - namely: // Parameters pin io float *vel_scale *"The scale to convert the Velocity signal to Volts"; pin io float *scale_offset *"The offset of the velocity input at 0 volts"; pin io float *velocity_tol *"The deviation percent from planned velocity"; pin io float *voltage_tol *"The deviation of Tip Voltage before correction takes place"; pin io float *correction_vel *"The amount of change in user units per period to move Z to correct"; So I plan to instantiate thc comp within my hal with: newinst thc thc0 vel_scale=0.00037866834 scale_offset=119000 velocity_tol=3 voltage_tol=2 correction_vel=0.0001 But what would be the values of those parameters? Also for using thcad 10V I would need encoder and it seems I would need to use: http://www.machinekit.io/docs/drivers/hal_arm335xQEP/ so: loadrt hal_arm335xQEP encoders=eQEP0 but where do i specify what are source pins that encoder is counting them in component?
