but I feel like my settings for my extruder accel/jerk are perhaps limiting how fast it can respond and pull back the filament before it oozes? Does that make sense?
Here are those values:
M566 X900.00 Y900.00 Z12.00 E120.00 ; set maximum instantaneous speed changes (mm/min) M203 X6000.00 Y6000.00 Z180.00 E1200.00 ; set maximum speeds (mm/min) M201 X1000.00 Y1000.00 Z20.00 E250.00 ; set accelerations (mm/s^2)
Yes that makes a lot of sense. Your Z axis is also really slow which can add to blobbing on layer changes.
Try these values
M201 Z200 E3000
M203 Z600 E6000
M566 Z60 E3000
Increased the values and it appeared to help slightly but not much. When originally calibrating my E-steps I dialed them way back and it helped the quality of my cube print. On the benchy I still get the feeling that I am over extruding because of all of the blobs. I have a Benchy on right now, and mid print I just took the extrusion factor down to 90% and there is a very clear and astonishing improvement in print quality.
I'm going to take my E-steps down 90% in the config and try again... I think this is the biggest culprit.
