Multi Extrusion - Prime tower too dense about curaengine

[Riffo]

Still have this issue in latest version of cura. Any chance the extrusion rate could be reduced when doing priming with 3 colours? am happy to make a bigger tower if required, just frustrating not being able to use it, trying to do off bed priming still for now to be able to use

I'm sorry, but multi extrusion simply does not has the focus right now.

i guess my problem, "Wipetower position" is a duplicate of this.

Riffo, did you find another slicer thats better for this? - I'm going with kisslicer for now, although I have retraction problems.

It seems as though the prime tower code depends on there being only two colors. My guess is therefore that the wipe tower in your clip has 1.5 times the volume it should have.

With two colors, we switch color once every layer, and so the wipe tower gets one layer each switch. With X colors, we switch (X-1) times every layer.

The problem could be solved by turning down the extrusion rate for the wipe tower, but then we would also need to adjust for the layer thickness.
I think a better solution would be to have (X-1) separate wipe towers.

This shouldn't be too hard to code; maybe someone else can find the time?

Hi @Riffo, I'm closing this ticket as we have integrated a new prime tower that addresses the issue you pointed out. You can try it on the last 5.7 beta.
