Speed affects extrusion rate with pellet extruder
-
I've been testing a Dyze Pulsar and I've noticed that the print speed very much affects how much plastic exits the nozzle. I've done some testing by printing 3-inch cubes with the same profiles, but varying the print speed, weighed them. I came to the conclusion that as the speed increases, so should the extrusion multiplier. I've created fast/medium/slow printer profiles in Simplify3D V5 that work well. However, as I was trying to create a post-processor that would modify the extrusion distance based on the feed-rate, I wondered if this was a capability of the Duet?

@p8blr you probably want to look at non linear extrusion and calibrate that

@droftarts Can you explain or link me to an explanation of this equation: (1 + min(L, Av + Bv^2)) ?
I read through the forum posts linked in the M592 description but I still don't understand the theory behind that equation, let alone how to determine the A and B coefficents.
Thanks.
