Thank you everyone!!!
I changed the Blob test to extrude 200mm of filament while moving 30mm on the X axis. This now makes amazing looking weld beads.
I can confirm that this fixed my issue. The M592 compensation does require an XY movement.
Looks like i can push a crappy hotend and a Titan Extruder to around 10 mm3/s.
Thanks everyone for your help!, I really appreciate the immediate responses and feedback.
I checked my Config-override.g and i do not call M592 (only in my config.g)
When i request "M592 D0" in the console, i get a return of "Drive 0 nonlinear extrusion coefficients: A=0.044, B=0.0000, limit=1.00".
Thanks for the asking me to check that.
Fantastic question. I am using CNCKitchen's Blob Test.
I had to modify an excel sheet i found online to make it work for a delta printer, but i am moving up 10mm while extruding 200 mm of filament.
Example: G1 Z10.5 E200 F12.473
This makes me wonder if a Z axis movement is not enough to activate the compensation....
Thanks in advance!
My 3d printer uses a Titan extruder and a standard brass nozzle.
I was performing some flow-underextrusion testing and found that the Titan Extruder has a very linear slip based on extrusion speed.
mm/s UnderExtrusion
1 0%
2 -3%
3 -3%
4 -7%
5 -11%
6 -15%
7 -18%
8 -21%
I learned about M592, did some calculations and want to add an "A" coefficient value of 4.44%.
I added "M592 D0 A0.0444 B0 L1" to my configuration file, as seen below.
Every time that i power cycle and attempt to do additional Flow-UnderExtrusion testing, i get the same results as before i added M592.
Am i using the wrong extruder number in M592? or is there some additional things needed to activate M592?
I have also upgraded to Firmware V3.4.6
