Slow and weird at 140mm/s on curvy/circular path

@cubexupgrade:
I never used firmware retract but it can be a good solution to manage this slider. Is it better to use it vs slicer ? And is it necessary to use it with pressure advance control M572 ?
The main reason I added firmware retraction is to handle mixing hot ends such as the Diamond. With these, all the filaments need to be retracted the same amount, regardless of the current mixing ratio. Firmware retraction in RRF does that.
Use of pressure advance is entirely separate. However, if you use a lot of pressure advance then you should reduce retraction, because at high printing speeds pressure advance will already do some retraction at the end of an extruding move that is followed by a non-extruding move.

Sorry i'm little newbie with this kind of code…
I will post more picture, the back is clean but the front less cause it have lot of curve.
I will do more print of this with less mesh to have a reference.
Thanks DC42 for your explanation. I will do some test.

I didn't setup a minimum layer time for cooling.

Sorry to butt in on the end of this thread but having just rebuilt my delta to fix an issue (unsuccesfully by the look of it) before swapping over to the DuetWiFi, from the 0.8.5 board, I've got a print running and decided to check for underuns as I to use S3D and have 0.9 steppers.
I got MaxReps: 5, StepErrors: 0. Underruns: 229 over about a 5 minute window.
Sliced with 3.02 of S3D at only 90mm/s.
Only noticed this as I wanted to baseline things before swapping
Copy of the gcode file zipped in dropbox https://dl.dropboxusercontent.com/u/28032744/chatimage/caselid.zip if that helps. -
S3D 3.0.2 is before the "reduce small segments" fix, you should probably update to 3.1. (I'm still running 3.0.2 and not having any big issues since David patched the motion planner queue, but it depends a lot on the STL poly count.)

Hi RC,
I've been using 3.1 since it was released, went back to 3.0.2 just to back track changes made since this "sloop error" arrived, thought i had found it but appears not. The machine has been pulled apart and rebuilt with careful attention to squareness and spacing. The small 30mm test cubes still lean the same as prior to the rebuild which points to something else.
Checking m122 after the print finished (about 2hrs) i had this…
MaxReps: 6, StepErrors: 0. Underruns: 5504Guess I'll bite the bullet today and drop the Duet WiFi in place with the latest firmware

If you haven't started that yet, you might like to try the 1.15 beta 3 release for the wired Duet that I just put on github.

sorry David, was sort of warmish today so got on with it, going to update the other thread with some details.
Cheers
