Insufficient extruder speed have big impact to print quality

Post by Jarda3d » Wed May 01, 2019 4:44 pm

I was try to print faster (see my print profiles) and there are insufficient in speed of extruder with smooth continuous feed. See volumetric speed.

I was do some measurements.... Springs unloaded or up to compressed near the max...Like that

Code: Select all

G92
G1 E20 F340
So the HQ profile is fully enough for default Titan extruders on A10M. But for High speed profiles is extruder feed too slow. Yes, Titan extruders are 3 times stronger than ordinary, but it is not sufficient to feed plastics with that power.

With near fully tightened spring reliable speeds are not over 80mm/s with 0.3mm x 0.56mm layer (about 120 with fresh new spring tightened, so have little paranoid reserve to spring wearing and plastics material).

There are dual drive extruders with belt (thingiverse, aliexpress), which I want to try it. So if you want to have bigger speeds, then extreuder driver need to be changed. You can have tuned profile, but if extruder is weak, there is that trouble.

So if you look to quality, firstly check if extruder is neough to feed your speed.
