Dear Forum, I see, I have to set the maximum velocity and acceleration in ini file at more than one place, like in [DISPLAY], [TRAJ], [AXIS_X], [JOINT_0]. I can also see in [JOINT_0], I need to set two times, one for Max velocity and acceleration and another for STEPGEN MAXVEL and MAXACCEL (25% larger than MAX_VELOCITY and MAX_ACCELERATION).
I don't have an idea what to set here. I keep it default like MAX_VELOCITY = 25 and MAX_ACCELERATION = 750 and follow the guidelines for 25% increament for stepgen velocity and acceleration. Some time I get error of max vel clipping/touching when I change the parameters of STEPSPACE, STEPLEN, STEP_SCALE, etc. And I really don't know how do they calculate. I decrease some value and get ok. My driver supplier don't tell me the value settings for STEPLEN, STEPSPACE, DIRSETUP, and DIRHOLD. And I need help to set them properly. Servo period is the heart beat of computer, I need help to set the value for that after doing latency test. Currently, I have set only SERVO_PERIOD = 1000000 in [EMCMOT] section, no other period setting is there. I just kept the default. Please explain the importance of above parameters settings. I am facing following error problem, my CNC stage is not moving at commanded high velocity due to these limitations. Thanks & Regards Suraj Kumar. _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
