Combing or retract, both ?

[Hergonoway 1]

Hi,

(I'm French, sorry for my english)

Printer info : Bowden extruder.

I'm currently slicing with 2.3 Beta, while combing option is enabled I've a side effect on large pieces : While traveling long distances tiny droplets of plastic are drop along the path, when the nozzle arrive at its printing destination there's not enought pressure so I'm in under-extrusion for the next move.

I tried to find my way by disabling the combing option and use retraction instead for moves over printed parts, but there's too many retractions in a short time.

Is there a way to have something between these 2 options, like enabling combing, but force retraction when travel move is over a certain distance in mm ?

I second that.

Or perhaps a Prime Nozzle after combing.

There used to be 'Retract while combing' plugin for legacy Cura. Did not try it but sounded very useful.

So technically there's no current solution for this problem ?

:( too bad Cura Beta slices well

You could try disabling Combing, enabling Retraction and increase the minimum distance before retracting .

let's bring back this topic, so still no improvement from cura about this problem ? :(

combing lack of option is still problematic for long bowden extruder.

Or maybe something like prime after a long combing move ?

Or if combing is off, cancel retraction under a certain distance IF the move doesn't cross the outer wall.
