I’m seeing two things with the new setup that I’m going to attempt to fix. First, there is noticeable ringing on flat faces, especially at high speeds. This is to be expected when you greatly increase the mass of the head with a direct drive. Second, there appear to be some very slight layer registration problems. I’m not sure if this is because I turned off backlash compensation or because something in the belt setup is loose. I hope to figure that out tomorrow, too.
On the positive side, because the k-factor can run at or near zero with direct drive, the print head can move and accelerate faster around sharp features which reduces print times.
