Modify Jerk & Acceleration: Question

Postby Sean » Thu Mar 19, 2015 6:47 am

So I have tweaked my jerk and acceleration in the "Configuration.h" of Marlin to try and improve print quality. I was getting some ripples around where the head changed directions. It seems to have made some improvement. However, it appears that I might be over extruding a little on the infills where the head suddenly changes directions to go the opposite way (around the perimeter). Is it possible that there is something else that I needed to change with the extrusion parameters somewhere else to compensate for the slower acceleration and jerk? That is to say, is the extrusion still coming out at a rate that is matched to the old settings? Thanks for any help!
