Granted this is old but I still dont see an update in product. Is there a way to stop the tower at a certain level OR cause the brim to print for each color(they by purging for color changes ) as brim does have a final height setting?
I have tried a couple ways to eliminate color bleed but it seems the tower is the only way that works but, when I am printing a logo with a depth of only .6mm(three or 4 layers) and then 25mm of single color I hate to waste the whole towers worth of material. A 20x20 tower seems to be required to completely clear the darker colors from the extruder before the white.
Also, for the purger line at the beginning. it seems to mix when I only select extruder 0(white) then the first lines of the white area of the print are tinted the other color (dk blue). with a big purge block20x20 I get rid of the blue but waste a lot of white. I have also tried printing the blue first then back to white but inevitably i get a line or two of blue on the plate before the white prints(fail).
what i'd like to do to solve it and not waste a bunch:
print white brim, white first two layers, then dk blue and white mix brim outside of white brim, then first two layers of that process, then dk blue brim out side of other brims then first two lates of dk blue...then repeat at white......etc. then I could stop the brim at layer 6(or what ever) and not keep printing waste for the rest of the height.
