Hello, I’ve wondered if there’s a way to just print with a new color without prime tower or purge, in order to have a gradual change of color. Kind of like those filaments that change color over the span of a few layers?
I was thinking trying doing that too - with some either random painted layer colour changes or bands, perhaps with some alternating changes near the transitions so that they fade in. Your can turn off the prime tower (on the other tab), plus also probably easiest to just set the multiplier at the bottom of the flushing dialog to a really low value like 0.01 or 0 - as this seems to set all of the totals to zero.
You should be able to turn off (most) of the purge by setting the flushing volume multiplier to 0 (or something close); but I would not turn off the prime tower if you are doing multiple colors or filaments (unless you are doing a full bed print and just want to yolo it). This could negatively impact the quality and strength of your print (and it the worst cases, cause a print failure)
When a nozzle is at or near temperature, doing nothing, even for a second, it has the potential to ooze out a little bit of filament. This can pose problems such as having an “air gap” where it anticipates filament, and/or a tiny “blob” that it ends up sticking to your part somewhere. Priming is intended to solve this. You could reduce the prime tower size and volume (the defaults are overkill) but take great care if you decide to turn it off.
