Flushing Colors WOW


Ok I get that we need to flush out the nozzle. Well dua. But why so much? Is there a setting to change this. I mean look there is enough material to do 2 more Benchy’s just in scrap. I haven’t gotten to the purge/wipe block yet, come on there is by weight 2 times the meterial in the block as the Benchy. Could we not have made this thing like a cross hatch or something. Whats with a solid fill we don’t do that on any part.
Someone please tell me we can fix this.
I was able to make a smaller tower and turn it off but the flush I am sure there has to be a setting from all the topics I have read. But I can’t find it. :confused:

This Bambu wiki should help

Thank you. :+1: Great information. I have to say this is the best forum.

I did a multi-color print and while the multi-color capability is nice, that is what generates all that waste. Imagine that you took that Benchy and unwound it so you had this long string. That would be like one long blue string with intermittent, TINY brown segments. Every single layer has blue and brown filament. on some layer lines you may have multiple blue/brown interfaces. In many cases a single layer has multiple color changes. EVERY single change from brown to blue to brown you get a purge cycle. Not sure what the green, black and white colors represent but if the bottom is white with the text being black which it sort of looks to be the case, those transitions are also going to get you a purge cycle.
When you slice that Benchy do you get the dropdown that tells how long it will take how much filament and how many layers?
In all that data will be a value for number of color changes. Slice that same Benchy and really look at the data. See how many color changes there are. That is where all the waste comes from.
Printer has to come up line by line. That also causes all the color changes.
The more you go from blue to brown really runs up your time to complete the print too. Down where you have the cabin and gunwale trim you have several color changes per layer. You throw in the time it takes to leave the print, travel back to purge area, purge, travel back to print and tally that all up the nozzle is off the print probably longer than it is on the print.
