Slow after changing extruder
-
Or "WHat accel / jerk / speed setting have i messed up now?"
I replaced my old extruder with a Orbiter 2.0, and used the recommended settings from their wiki.
BUt, for some reason my printer is now extremely slow on (especially) gyroid infill. And I can't figure out what I may have misconfigured.

M566 E300
The orbiter jerk is quite low. With pressure advance there's going to be some direction changes for the extruder and it'd going to have to slow down to your jerk setting for that.
Have you retuned your retraction pressure advance settings after changing extruders?

Groaaaan.. I stared at only the extruder settings as such for too long. I THOUGHT i had disabled PA and was going to re-tune after shake down.. Yeah, need to retune that and prolly go a bit higher on M566 orbiter says "Up to 600mm/s"
Thank you.

@janjoh your pressure advance value 0.25 looks way too high for an extruder mounted on the hot end, which I presume your Orbiter is.

No. Flying extruder. Approx 20cm of bowden above a Smart effector.
HOIWEVER. Something must have been really off with the previous extruder, because "The Ellis Guide" gave me 0.25 PA.
As it looks now, i seem to be in the 0.04 range. (and yes, i am CERTAIN that the old extruder landed at 0.25 and not 0.025.. I promise)
-
In the end, i ended up at PA of 0.12
