I said “perform like” maybe you skipped past that part? So what is closed loop vs what Centroid did with the Acorn? I never really understood the difference with the Linux system since it’s running on a pc not the control board? I thought it had to do with the pc controlling the motion vs the controller board? Doesn’t the BBG processor handle the actual G code movement vs the windows pc on other controllers? Or does closed vs open have nothing to do with what controls the motion? I honestly haven’t read that much about either other than everyone always is like “you have to have closed loop this or that “ I understand closed vs open on steppers since the encoder keeps absolute position of the motors or spindle. Please explain to me what a closed loop controller is as well as the benefits, also tell us how the Acorn works since apparently I’m incorrect assuming that the BBG on the Acorn handles machine movement and apparently it’s there for some other unknown reason.
Thanks
