Stringing: Retraction and Travel speed
-
I get it now - I guess I have to turn the wipe off.. and correct the {REPLACE "G1 E0.0000 F7200\n" "G11\n"} to use relative values
-
@drammy did that help solve the stringing?
-
@phaedrux Not particularly, I see there is a setting in Simplify3d to retract whilst wiping so I need to test turning that off and then I should be able to use wiping.
I'm running out of ideas of how to remove the stringing..
I've found that, with this specific material, if I slow the retraction down there is less stringing but still a significant amount. I'll take a pic when this print is done
-
@drammy have you seen this yet? Your dilemma inspired me to create some macros to ease retraction tuning.

@phaedrux I hadn't seen them; I'll start using them straight away. Thanks again!
I've come to the conclusion that the filament I was using was simply terrible filament. I've stopped printing the model I was trying to (1st pic below) and have just taken delivery of some Filamentum Extrafill PLA which has shown absolutely no stringing whatsoever with your settings. The 2nd pic is the temp tower test I did (literally the very first print with this new filament)
Note: I did dial down the retract speed for the first print 7200 -> 2400. I am new to this filament and not being familiar with it led me to lower the retract speed until I learn more about its viscosity. I didn't want it snapping with high speed retracts.
Looking at the 2nd pic suggests to me that I need to introduce some negative R values as the point after a retract seems to over-extrude a bit. The whole print is generally over extruded but that's the next task now I know the print temp..
